FGB-5000 Mini VFO Display

Home made small utility (beta) may be useful just to see a status aglange of which is the RX and which is the TX VFO and the correspondig frequencies. I’m not a professional programmer so this is just one toy for my need and for my learning purpose.


  • PC with Windows 7, 8, 8.1 or  Windows 10. It should work also on Windows XP and Vista (never tested).

  • Microsoft Dot Net 4.0 Framework libraries (normally already installed in 99% of the computers today). If you don’t have it, you can download and install it for free from the Microsoft official web site at : https://www.microsoft.com/en-us/download/details.aspx?id=17851

  • CAT interface connected to the RTX (just a serial cable is enough).

  • RTX Yaesu FT-5000 (with latest firmware) connected to the PC via serial port (or via USB Serial Port emulator).


At hardware level, if you already have a computer connected to the RTX (for example for same Cat control program as Ham Radio Deluxe) you don’t need anything else.

Once downloaded, just put the EXE somewhere, where do you prefer, no need to install. You can run it just with a double click, No external libraries needed. If you don't like it, just delete it and it's gone (no need to unistall).



Select the serial port attached to the FT-5000.

Select the same baud rate as in the FT-5000 menu 032.

If your serial interface (or adapter) and your cable support hardware handshake, then you can flag RTS and set menu 034 di enable (most case this will be non flagged and menu 034 will be disabled).

Set a refresh rate. Faster polling (100 ms) will gives you a responsive interface but will require more CPU. Slower polling (2000 ms) will update less frequently but require almost nothing as PC resorces.

Click Connect.

You will see VFO-A TX and RX frequency on the left and VFO-B TX and RX frequency on the right.

With default colors (changeable), the RED backgroud means that this is the TX frequency on the corresponding VFO.

Green background means that this is an enabled RX frequencies on the corresponding VFO.

Grey background means that that Rx or Tx VFO is not in use.

In the following picture, you can see :

Your TX frequency is 14.200.000, using VFO-B

You RX frequnces are 14.195.000 with VFO-A and 14.200.000 with VFO-B.


You can enable/disable Rx and Tx of each VFOs, clicking on the corresponding RX TX push buttons (same behaviour as in the RTX).

In the following picture, you can see :

Your TX frequency is 14.195.000, using VFO-A

Your RX frequency is 14.200.055 using VFO-A WITH RIT (RX Clar is enabled).


You can enable/disable RIT or XIT clicking on RX Clar and TX Clar buttons and adjust Rit/Xit using the track bar. The new frequency (dial + rit/xit) will be updated in the VFO-A display.
