Reference Material

This page contains a list of reference documents. Some I have put together, and some publicly available produced by others or by manufacturers.  I found these documents very helpful to me and a good reference material when needed.


  • Wiring Diagram between YAESU FT1D and Kantronics KPC 3+
    • KPC3 TNC to TRx MIC-SPK Wiring Diagram
      • This wiring should help connect your VX-8DR or FT1D to KPC 3+ TNC for operations such as APRS Digi and iGATE, WinLink RMS Express (both user and SysOp mode).
      • Note also you will need a solid external antenna connected to the HT if you really want to get that coverage range.
        • In my WinLink RMS Express user mode, operation, I hooked up my YAESU FT1D to my J-Pole Antenna (no gain roof top installed) and was able to operate RMS Express via a nearby repeater w/ a much larger antenna coverage.
        • In my WinLink RMS SysOp mode operation, I connected my FT1D to my 11db gain Comet GP-9 antenna and was able to operate in the SysOp mode very successfully.
      • Note also that you will need to ensure your connection between KPC 3+ TNC to your PC via the serial port on the TNC.  Please refer to the pages 30 to 43 in the Kantronics KPC 3+ Manual : KPC-3PlusmxRevG
      • Refer to my TNC-To-Go Project for added details

  • Tip to install velcro’d batteries and other objects into tightly constrained container areas
    • Application : Solar Powered battery power to-go stations;
      • Here’s an idea to install velcro’d batteries into tight areas in containers (such as into ammo cans while building solar powered to-go boxes) w/o having to wrestle in.
        • Take a few printer papers; place the papers on the Velcro sides of the battery; place the battery snugly into place along w/ the paper overlaid on its velcro’d sides;  once you have placed the battery into place, slide out the papers one at a time ensuring that the Velcro makes strong contact w/ the container’s Velcro.  repeat the paper removal till all sides of the battery’s Velcro are secured.  Same thing w/ your multiple batteries;  This idea is especially useful when placing objects into tightly constrained areas/enclosures w/ objects w/ multiple velcro’d surface areas 🙂
        • The printer papers provide the needed insulation btwn the two Velcro surface areas, while giving you the needed room to fit your batteries into place w/o having to wrestle them in.

    Hi John,

    I tried to get in touch withyou ,but didn’t find an email adress. anyhow.

    I find your poject “Remote Control Motorola XPR+SLR RIGs”.

    I was looking for a solution to connect to my FT-991 through the LAN.

    On one of your pictures I saw that you also own a FT-991.

    Have you ever tried to connect to it using vitual here?

    I would like to get your feedback on that.

    Thx & 73

      hi Juergen – sorry about the delay. I used to have an FT-991. However, I had sold it to a good home. I since purchased an IC-7800, which is my primary HF rig. For FT-991, I also recommend pairing the virtual here w/ the FT-991’s RS232 command set. I had started a project to do some “custom” rig control w/ it, but, did not have a chance to wrap up that project. Ideally, a solution would allow you the operator to select a “use case” from a drop down and then, the radio settings will automatically be configured to work that “use case”. An example would be, let’s say you want to work PSK31 or JT65, each of these will be available as options in your drop down, when selected, the FT991’s “data” settings will be configured to work just perfect for that user scenario. Pairing this up w/ Virtual here, you could potentially control that rig as if it were your local USB COM PORT

      just an idea. Best wishes
