New Source for G4HUP PAT boards.

FYI, someone has began producing the original G4HUP boards by Dave Powis (SK). They are once again available, being offered at, G4HUP boards

Thanks to Chun, G7NQL/VR2UPP for bringing that information to my attention.

The Blog...

Fellow Amateurs, I've lost most of my interest in blogging. I have decided to cease writing on this blog.  However, I have received positive feedback regarding several of the technical articles I've written.  Therefore, rather than delete the Blog, I have condensed it down to those articles that drew the most interest from the amateur community.  I plan to close down my station this year (2017) and relocate.

An IF Based Panadapter for the FTDX-1200

UPDATE: 6/23/2017: It has been brought to my attention, that Dave Caki, KD2C, is offering similar boards, he can be reached at  

NOTICE: Due to the sudden passing of G4HUP in February 2017. The availability and future of the G4HUP PAT board is uncertain at this time.  There has been speculation, that one of Dave's friend may carry on the product line, but at this time nothing is known in that regard. 

In the interim, I am actively seeking a suitable replacement board.  If something is found, I will update the blog with that information.

There is a kludge to tap the IF.  Rather than using the active buffer board with the filters, a small disc capacitor can be soldered to the same leg of the relay noted below. Some amateurs have tapped the IF that way. It's not something I prefer, because we lose the benefits of the buffer, but it will function and provide a signal to input into an SDR. I haven't heard of anyone sustaining any damage to their radio using the kludge, but proceed at your own risk.  A German amateur has the details on his QRZ page.

Recently, I've been contacted by several individuals regarding my installation of an IF out connection for a Yaesu FTDX-1200, utilizing the G4HUP PAT board.  A key building block to achieve a working IF based SDR Panadapter.  Similar to a FTDX-9000 I previously modified, the FTDX-1200 does not come from Yaesu with a factory installed IF out jack.

Both the FTDX-9000 and the FTDX-1200 share the same IF frequency of 40.455 MHz. The correct G4HUP PAT board to purchase for the 1200 installation is the model PAT50M (G4HUP PAT board). If someone is not accustomed to working with small surface mount components. I highly recommend ordering the assembled version, and also an installation kit from Dave, G4HUP.  The installation kit contains all the parts necessary to install the PAT board into the transceiver.  Several individuals on the web, have directly tapped the IF on the FTDX-1200, without using the PAT board.  IMO they do so in a haphazard manner.  Directly tapping the IF, offers no protection or constant signal from the IF chain in your expensive transceiver.  I recommend the PAT board for reasons set forth in this article published in RadCom.

The addition of an IF out jack on the FTDX-1200 is not too difficult.  Unlike the FTDX-9000, it is not necessary to remove any circuit boards or dissemble the radio beyond removing the cabinet.  The installation is straight forward, and only requires a wire to be soldered between the PAT board to one leg of a relay, a wire soldered to a test point to provide DC power to the PAT board during receive, and a convenient ground connection to the PAT.  The last connections are the two ends of a length of Teflon coax between the PAT board and a rear mounted SMA socket.  All connections are made on the component side of the transceiver's main board.

First, remove both halves of the cabinet and set them aside. Next, I recommend that the chassis is carefully drilled, and prepared to receive the rear mounted SMA connector.  I found a convenient spot on the FTDX-1200 near one of the rear corners of the chassis.  However, before you mark the spot to drill the hole.  Ensure the planned location for the connector and hardware, will clear the circuit board, and any protrusions that are inside the chassis.  During drilling, it's handy to have a friend vacuum the loose aluminum shavings, to prevent them from accumulating inside the radio.

Once the chassis is prepped to accept the SMA connector.  I recommend to refrain from installing it until after the PAT board is installed, and the Teflon coax has been installed onto the SMA connector. It's just easier to attach the coax while the connector is on the bench.

The first connection between the PAT board and the radio is for the IF tap. The connection location in the FTDX-1200 is on relay RL1007.  A small wire will be soldered from Pin 3 on RL1007 to the PAT board. The PAT board is marked "IN" on one end. There are three solder pads on that end of the board. The pad in the center is where the IF TAP wire will be soldered to the PAT board.  Dave G4HUP, highly recommends using the small wire from the kit to make that connection, and to use double sided tape supplied in the kit to place the PAT board as close as possible to the IF connection in the radio. There are metal shields on the circuit board that are close to RL1007. The shields make a good solid base to secure the PAT board in the radio. Just ensure the PAT board will not short out against the shields. I found that using a thicker material (Velcro) worked just as well to secure the board. It also provides a bit of spacing between the shield and the PAT board to prevent any short circuits.

Component side board layout, showing tap point on RL1007.  The connection is made right to the third leg from the left on RL-1007 (facing the front of the radio).

The next connections are to provide DC power and DC ground to the PAT board.  Towards the bottom edge in the middle of the PAT board, there are two solder pads. The one closest to the bottom is for ground and the one above it is for DC power.

The technical supplement for the FTDX-1200, indicates there is an RX9 line that terminates on the main board at TP1002.  A connection to TP1002 will provide 9 volts DC to the PAT board during receive. The ground wire from the PAT board can be soldered to any convenient DC ground point.

Location Area of TP1002 on the main board...

Component side board layout, showing DC positive RX9 point on the main board (TP1002).  (Facing the front of the radio).

The final connections are made using the Teflon coax provided in the installation kit, between the PAT board "OUT" and the rear SMA connector. If not already done, solder the coax center conductor to the center pin of the SMA connector, and the shield to the outer body.  Install the SMA connector in the rear chassis hole that should have been previously prepared.  Carefully route the coax through the chassis up to the PAT board.

Leaving a generous amount of slack coax between the PAT board and the SMA connector. Cut the coax and solder the center conductor of the coax to the middle "OUT" solder pad on the PAT board, and the shield can be connected to either one of the solder pads above or below the center pad as shown below.

The PAT board installation should be complete. Double check all connections, and reassemble the radio. In regard to the SDR radio. Myself and several other hams I know, have had good experience using the RTL dongles from Nooelec. They seem to be higher quality than the run of the mill Ebay/Amazon RTL dongles.  I certainly have not experienced some of the issues and poor performance noted by others using the generic RTL 2832 devices available on Amazon and Ebay.

A Panadapter using HDSDR and a RTL 2832U dongle.

In relation to the modification I recently performed to a FTDX-9000MP, adding a dedicated IF out port to support a computer panadapter.  A software package and SDR receiver is also required to complete a working panadapter system.  In researching the subject, I noted that many amateur stations have acquired a sufficient panadapter using the program HDSDR, and a simple RTL 2832U SDR USB dongle.  I decided to utilize that same method as well, and have been pleased with the results.

In addition, I also use Ham Radio Deluxe version 6.2, as my main rig control and logging program.  In my station, HDSDR serves as the panadapter display program, and slaves the SDR receiver's frequency to the main VFO of the FTDX-9000.  The below information and settings in HDSDR are in relation to the HRD/HDSDR combination. There are some minor differences in the settings for HDSDR, when HRD is not used, but I have not noted those settings.


To complete the hardware, I purchased an RTL 2832 SDR receiver from the company Nooelec, RTL Dongle.  It includes a 0.5 ppm TCXO and the newer 820T tuner.  That combination has proven to be adequate, and the particular dongle I purchased, also included a well made aluminum enclosure to assist with shielding.  Additionally, I ordered cables with the required connectors, to ensure I was able to connect the RTL SDR between the radio and the computer.

HDSDR/RTL Dongle Drivers:

Once the hardware is in place.  HDSDR and the correct driver for the RTL 2832U SDR receiver must be downloaded. To install the driver and HDSDR, follow the instructions provided on the HDSDR Hardware page for the RTL dongle, Instructions RTLSDR.  The basic instructions should get the SDR receiver communicating with HDSDR.


Once HDSDR is installed and the RTL SDR receiver is functioning, several settings need to be adjusted to ensure proper operation.  Below are the current settings in HDSDR I am using in my station to provide a panadapter for a Yaesu FTDX-9000MP.  Some of the settings may be specific to my station, because as noted above, I also uses Ham Radio Deluxe as the main logging and transceiver control program. HRD handshakes with HDSDR to provide the panadapter tracking. Some settings, such as the soundcard and bandwidth, may be dependent on the individual station's computer.

First, to the right of the Tune frequency display on the main GUI for HDSDR, there is a button labeled ExtIO.  Depressing that button, causes a small box to appear, and displays information about the device in use.  If the device driver was installed correctly, it should show a RTL2832 as the "Device".  In my station, the sample rate was automatically selected as 2.4 Mpbs, as was the Buffer Size (16kB).  In the lower right corner of the ExtIO pop up box, there are three check boxes. The boxes labeled RTL AGC and Offset Tuning should be checked and the Tuner AGC box should remain unchecked.

The other operational settings are adjusted by using the buttons located on the left bottom corner of the screen. Those buttons activate sub-categories and menus as follows:

Sound Card Selection (F5)
RX Input (from Radio): Line In (IDT High Definition Audio)
RX Output (to Speaker): Speakers/Headphones (IDT High Definition Audio)

Bandwidth (F6)
Input: 2400000
Output: 12000

Settings listed in the subcategories and menus under Options (F7) should be set as follows:

Select Input:  Generic RTL 2832U and MME 16 Bit Drivers, should be selected.

Visualizations:  The settings in this sub-menu default with eight options selected as shown.

Input Channel Mode for RX: I Left / Q Right, should be selected.

Output Channel Mode for RX: AF to Both Channels, should be selected.

Clicking Input Channel for Calibration for RX, brings a pop up box as shown below, the setting for Mode: located in the top right corner should be changed to AUTO. All other settings are kept at default.

Swap I and Q Channel for RX Input, should be checked.

Misc Options: Normal Process Priority (default), should be checked.

Mouse Wheel: Directions Inverted and Mode Tune, should be selected.

RF Front End + Calibration is set as shown below. These IF frequency may be specific to my SDR receiver:

Recording Settings /Schedule is set to default.

DDE to HDSDR is set as shown below:

CAT to Radio (Omni Rig) is set as shown:

All CAT to HDSDR settings are at default.

An IF Based Direct Sampling Panoramic Adapter for the Yaesu FTDX-9000...

FTDX-9000MP + HDSDR + Ham Radio Deluxe....

As an owner of a Yaesu FTDX-9000MP.  I've always felt fortunate to have such a beautiful transceiver included in the line-up of the HF transceivers in my station. It truly is a work of art in design, performance, and quality of hardware.  Nevertheless, there has always been one item that is not factory installed on the FTDX-9000, one that I felt should have been included. That is a connector to obtain a signal from the first intermediate frequency path in the receiver.

I've always enjoyed experimenting with new trends in technology. Recently, with the introduction of moderate priced RTL SDR dongles, and several freeware programs. A useful real-time panadapter has quickly became a common addition to many ham radio stations. Naturally, I also wanted to add that capability to my station as well when using the FTDX-9000. There are methods to implement a panoramic adapter when using a modern transceiver that does not have IF out capability.  However, some of those are cumbersome.   I believe the most effective method is based on a signal directly from a transceiver's immediate frequency after the first mixer.

During a QSO,  I mentioned to a knowledgeable friend, Greg K3EWZ, that I was investigating a way to add a panadapter to the FTDX-9000 platform.  However the problem I was facing, there was no IF out connection on the FTDX-9000.  Greg was kind enough to provide technical guidance about the circuits in the FTDX-9000, so I could implement an IF out signal connector for the FTDX-9000.

A high impedance interface board with filtering, and adequate reverse protection is required to add an IF output signal connector to a transceiver.  A search for information, led me to the web page of Dave Powis, G4HUP.  Dave produces several high quality surface mount Panoramic Adaptor Tap (PAT) Boards, that also includes the necessary low pass filter and reverse protection to fit many different transceivers.  The first IF frequency of the FTDX-9000 is 40.455 MHz. Therefore, I ordered a fully assembled "PAT50M".  The "50" designates, the PAT board includes a 50 MHz low pass filter.  I also ordered a generic socket installation kit. The kit included most everything required to install the board.  However, because of the large size of the FTDX-9000 chassis. It's also necessary to obtain additional Teflon coax to reach between the tap board and a rear mounted SMA connector. I used RG-316.  However, RG-178A is recommended by Dave, G4HUP.  Dave also sells several other interesting items, and has additional technical information about the PAT boards on his website.

Note: Please see the addendum at the bottom of this page for additional comments and recommendations received from Dave, G4HUP, regarding the installation of the PAT board.

The procedure to install the Panoramic Tap Board (PAT) necessitates performing some minor disassembling and alterations to the radio. That includes removing the main receiver (RX-1 board), and drilling several small holes in the back of the radio's rear chassis to install a SMA female connector.  Anyone considering this modification, should obtain a copy of the Technical Supplement (TS) for the FTDX-9000. A PDF copy can be downloaded from several sites. Information in the TS is critical as a reference, and should be kept on hand for review before and during the modification as necessary. The procedure below is specifically for the FTDX-9000MP. There may be differences between the various FTDX-9000 models. Individuals should verify through review of the technical supplement, that the information provided herein is applicable to their particular transceiver. 

The block diagram for the "MP Type" reveals, that after a received signal passes through the mixer circuitry, the first IF 40.455MHz signal is routed through the Mixer Switch Relay (RL-1010). Then, the signal branches out to the input of three relays, the beginning of the roofing filter switching matrix for bandwidths of 3KHz, 6KHz or 15KHz.  It is at that point the first IF signal chain should be tapped, after the first mixer, but before the roofing filter(s). The schematic diagram for the RX-1 Unit is consistent with the block diagram, reflecting that Pin 3 of RL-1010 is physically connected through a branch circuit to Pin 3 of Relays RL-1011, RL-1012, and RL-1013. A review of the RX-1 Parts Layout page in the TS (RX_1-3), shows the physical parts placement of the relays on the component side of the board (Side A) at section G-1.

Another consideration to installing the PAT is to provide the required power to the board.  The recommended voltage is between 8 and 12 volts. The circuit diagram shows an interconnect line designated as RX9, representing that line is high during receive, providing approximately 9 volts.  That line terminates on the component side of the RX-1 board at TP 1014.  The RX-1 Unit Parts Layout diagram shows TP 1014 at section H-3.  TP 1014 is simply a small solder pad. To provide power to the TAP board, a small wire is soldered between the PAT and TP 1014.  That is the only connection that will be made on the component side of the board. The other connections are on the solder side (side B) of the RX-1 board.  The area on the solder side of the board where the connections will be performed are shown on the RX-1 Parts Layout diagram for "Side B", in sections 1-B and 1-D.

To begin, the bottom cover from the FTDX-9000MP must be removed.  Loosening the screws for the side covers helps ease bottom cover removal.  Once the bottom cover is removed, that area reveals several boards, including the two identical receiver boards (if so installed). The RX-1 board of interest is installed in the center of the radio, and is for the (main) VFO A.  To remove the main receiver board. It is first necessary to remove a few other components.  However, before removing any components. I highly suggest that multiple photographs and detailed notes are taken to ensure that adequate information is available to assist when reassembling the radio. The FTDX-9000 has multiple connection points on the RX-1. Some connectors look identical, and making an error is possible, unless there is adequate references beyond what is provided in the technical supplement.

To remove the RX-1 board, working from the front of the radio, there are two metal shields that have a conductive tape bridge between them, one shield is mounted on the VFO A RX-1 board, and the other is mounted to the VFO B RX-2 board.  It is not necessary to disturb the tape. Rather, remove the five screws that secure the shields, remove them as a unit, and place them to the side.  No other components will be removed from the VFO B RX-2 board.

Shields on RX-1/RX-2

The next component to remove is the BPF-1 unit from the VFO A's RX-1 board.   It is mounted under the shield that was just removed from the RX-1 board. The BPF-1 is installed on two pin style header connectors, and is secured by two hexagon fasteners.  First, remove the two hexagon fasteners, and then remove the BPF-1 by gently lifting both sides of the BPF-1 equally to release the board from the connectors.  Once the BPF-1 is removed, the screws that secures the RX-1 board to the chassis are accessible.  Next, remove the screws, disconnect the associated wiring from the on-board sockets, and remove the board from the chassis.

BPF-1 on RX-1

Once the RX-1 board is on the work surface, installation of the PAT board can begin. As described above, there are only three connections that must be soldered to the RX-1 board. One on the component side at TP 1014, and two on the solder side, the IF tap point and a ground.  Referring back to the technical supplement, RX-1 Part Layout Diagram, Side B, at B-1. The layout shows the tap point where the center conductor of the RG-178A coax that is included in the generic socket kit will be soldered to Pin 3 of RL-1010.

Below is a photo of the actual tap point on the RX-1 board. There are the eight pins on relay RL-1010 shown in the photo. From this orientation, the connection is made to the top row, second pin from the right.

Once the tap point has been identified, the PAT board should be installed close to the connection point.  I used Velcro to attach the PAT board to the RX-1.  After the PAT board is in position, the RG-178A coax provided in the connector kit can be installed from the RX-1 tap point to the PAT board.  It is unnecessary to solder the shield of the coax cable to RX-1.  Only the center conductor of the Teflon coax cable should be soldered to the RX-1 board.  The PAT board conveniently provides  two grounded solder pads for the coax shield on each side of the signal input solder pad.  Only one is used, and provides flexibility in orienting the cable during installation.  The second connection from the PAT board to the solder side of RX-1, is simply a DC ground. Any convenient attachment point that goes to ground can be used for that connection. 

As noted above, the final connection that involves soldering to the RX-1 board is the 9V+ DC supply point. That wire is soldered to TP 1014 on the component side of the board, and the remaining end is soldered to the PAT board. I found it was easier to solder the wire to TP 1014 before attaching the wire to the PAT board.

Final connection before installing the RX-1 back into the radio is an approximate 28" length of RG-316 to the PAT board's output solder pad. Once complete, the RX-1 board can now be installed back in the radio, while carefully routing the unterminated RG-316 towards the rear panel SMA attachment point.

The installation of the SMA female connector is fairly straight forward. Simply install the SMA connector in the rear panel. Solder the center conductor of the RG-316 to the center pin of the SMA connector, and solder the shield to ground connector supplied in the generic socket kit.  I installed the SMA on my FTDX-9000 in the left corner of the rear panel, which seemed to be the most open area available on the rear of the FTDX-9000's chassis.

The G4HUP PAT board is working extremely well, and am pleased with the addition of an IF out connector for the FTDX-9000.  I am still experimenting with various software pan adapter programs, most recently as shown in the top photo, HDSDR+Ham Radio Deluxe+Yaesu DMU all working together.   Bandwidth coverage is more than adequate. As an example, on 20 meters when using the FTDX-9000 and HDSDR,  I can expand the panadapter to a span of nearly 2.4MHz (13.000MHz to 15.400MHz).  Side by side testing of the main receiver against the unmodified identical sub receiver, does not reflect any adverse affects from the installation of the G4HUP PAT board.

Second view, showing activity during a recent CW contest at the bottom of the 20 meter amateur band.

ADDENDUM: I received the following useful comments and recommendations from Dave G4HUP, the designer of the PAT board mentioned above.  His comments should be considered when contemplating the addition of a PAT board/IF out connector to the FTDX-9000.

Dave notes, that based on the expansive spectrum of 2.4 MHz I can view with the Panadaptor.  It's assumed that I tapped the IF signal path before the first IF filter.  In doing so, there may be unwanted mixer products visible in the display, and can be identified as signals that tune in the reverse direction of genuine signals that are present in the display.  Although I have not yet noticed the anomaly of erroneous signals using HDSDR and the modified FTDX-9000mp.  I cannot guarantee that will not be an issue for other individuals that perform the modification.  During previous testing by Dave on a Yaesu FT-897. Tapping the IF signal before the IF (roofing) filters, resulted in mixer products that rendered the panoramic adapter display unusable for the user.

Consideration of using a different tap point within the IF signal path may be more appropriate.  He recommends, that if the PAT board input is connected after the IF filter, the visible spectrum is less, but all signals present in the display would be genuine.

In relation to the installation. He recommends not using coax for the input connection to the PAT board. Rather, recommending using some of the fine wrap wire supplied in the connector kit. The wire is lower in capacitance than coax, and reduces the risk of excessively loading the tapped circuit.  Additionally, the PAT board should be mounted as close as possible to the tap point using the double sided adhesive tape supplied in the connector kit.

Finally, he recommends a better coax to use in this type of installation from the PAT board to the SMA connector is RG-178A rather than RG-316, which is 1mm smaller in diameter, and therefore easier to handle.

Update: I recently installed a PAT board in a Yaesu FTDX-1200, because the FTDX-1200 is another radio that does not provide an I.F. out connector on the rear panel.  In that configuration, similar to the installation I performed on the FTDX-9000.  I also tapped the IF path after the first mixer, but before the roofing filter.  Additionally, instead of using coax for the input connection on the PAT board. I used fine wire as suggested by Dave, G4HUP.  That installation also did not reflect any erroneous signals or mixer products on the panoramic display.  The owner of that FTDX-1200 is extremely pleased with the results.

Tower Passes Final Inspection

As a conclusion to the series of posts about the installation of the tower, the final inspection of the tower occurred, and it passed without any notable issues.  Right now, I am more into working on my mobile, therefore the tower will sit idle as I focus on the mobile project.  I have a tendency to work on multiple projects at the same time, so it is not unusual for me to jump from one project to another. I recently acquired a new mobile HF rig, a Kenwood 480SAT.  More on that later.


The tower project moves forward...

How much does it cost to purchase and install a new heavy duty tower? That is a question many radio amateurs ask when considering a support structure for their antennas. Therefore, I am documenting my tower purchase (US Tower HDX-572) and installation to show my out of pocket expenses and experience. I am performing the tower installation myself, therefore I will save some on labor. The tower will require a building permit, I will include those costs too. So far I have my plans in hand, cost $600.00.

Next stop,the Warren County, Va building department.

Today, August 6th, I dropped off my plans and building permit application. The application cost $61.00, so far so good, the permit technician was quite helpful. A pleasant change from my prior experience with another permit technician who was a little rude.

Total: $661.00

Good news, the county approved my tower as proposed, so it is on with the show. It's Friday August 27th, 2010. I visited a local concrete tool dealer who also works with rebar. I asked for a quote to build the rebar cage that is required for the tower. I provided a copy of the plans and the phone number to U.S. Tower, just in case they may have any questions, no price on that yet.

It is also time to get started digging the 5x5x8 hole. At eight feet deep, digging through Virginia clay and rocks by hand is out of the question. Therefore, tomorrow a rented backhoe is being delivered to handle the digging chores. The cost for delivery, pickup, fuel, and rental for two days came to $541.50. I also needed wood for the form and marking paint, cost on that was $24.37.

Mother Earth Intervenes:

We attempted to dig a 5 foot square hole as required for the tower. However, we ran into a large shale deposit which required additional digging. The hole has now grown to 5 X 8 X 8. The unfortunate thing about shale, it has a domino effect when disturbed, so it basically caved in on one side, causing a void when we attempted to dig out the hole. Now, I have to go back to the engineer to see what needs to be done, if anything to compensate for the additional size hole.

September 1, I inquired with U.S. Tower about the over excavation. I was informed that I could either frame up the one side, pour the concrete, wait a week, and then carefully back fill/pack the excessive void, or I could just fill the void with concrete. I have opted for the later. I hope the county inspector agrees after reading the email from the P.E. at U.S. Tower. In regard to the rebar cage, the subcontractor (Action Concrete of Winchester, VA) has quoted a price of $380.00 plus tax ($19) to complete the cage.

September 10, Today, I order the tower and associated hardware, with shipping the total came to $15178.00. I also picked up the rebar cage, they did an excellent job, better than I could have ever done. Next step will be the drainage gravel, framing the foundation, and concrete.

This weekend, September 18-19, I spent most of the time trying to get the rebar cage set into the foundation, and constructing the concrete form. U.S. Tower mailed the base and foundation bolts to me in advanced. I needed additional lumber to make the form, and some drainage rock. The lumber came to $23.52 and 30 bags of drainage rock was $116.87.

After installing the drainage rock, I discovered that the rebar cage was not sitting deep enough in the hole. To remedy this issue, I had to hand dig out several inches of rock to square up/deepen the hole. I spent several hours working at this with little progress, so I decided that an electric jack hammer would be required to complete this task within a reasonable amount of time, rental price was $69.30.

Total to date: $17013.56

10/1/2010: Today, the project was inspected and approved by a county building inspector. Next, comes the concrete and delivery of the tower.

10/11/2010: The concrete arrived today, it took approximately 11 yards of concrete to fill the void in the ground for the tower base, I used 3500 psi concrete with fiber reinforcement. Myself, my wife, and my sister-in-law, served as the concrete crew for this stage of the project. Both have been very supportive and helpful throughout all stages of the project. I could not have done it without their assistance. The cost of the concrete came to $1184.40, and rental for a concrete vibrator for one day was $43.00.

10/17/2010: Not much new to report on the tower project, except that we removed the concrete form from the base. As a word of advice, always put thought into how the concrete form will be removed after the pour. I had a very difficult time removing the wood form from the base. I literally had to split the wood along its grain in bits and pieces to remove it from the base. It took several hours to remove two sides of the form from the base because it had become entrenched with concrete on both sides of the board.

I was informed by U.S. Tower and the trucking company that my tower should be delivered on Tuesday, November 2. In anticipation, today I mounted the T-Base plate onto the foundation base. The base fit without any issues. As another word of advice, make the holes in the wood frame for the threaded rod somewhat larger than the rod, I had a lot of trouble removing the frame from the rods after the pour because the wood had swelled from the moisture.

The tower arrived today, without any issues getting it off the truck. I was not sure if I could move the tower with my Kubota tractor, but I managed to get it into position. The bill of lading shows the shipped tower with the raising fixture weighed 1848 pounds.

11/24/2010, The tower is now mounted on the base, leveling the tower was easy using the leveling nuts, and the T-base has been grouted. Except for grounding and wiring the remote, the tower project is mostly complete. Next, I will be considering which antenna(s) to purchase.

Except for grounding, the project is at a standstill until next spring. The tower project was a lot of work, but it gave a sense of accomplishment too by doing the work myself, and I learned a few things too along the way. I had to purchase a couple of bags of concrete grout to complete the base, cost was $16.78

The cumulative tower project total was $18257.74

Here are some photos of the tower installation project:
