Hello, it seems to be a great software, thanks for it.
Anyone using it with DX Patrol upconverter? Is it possible?
Thanks

Good idea, but unfortunately the connectors on the CT-62B cable are made of non-removable molded plastic. I can't get inside to desolder anything. Anyway, Frank says there is no TX GND internal connection on this cable.

TX and red means that the FT-817 is in transmit mode. Otherwise there ist a green RX icon. The PTT state is detected by PTT GND signal from FT-817.
Low state of CTS or DSR or DCD or RI from TTL/USB-Converter will be indicated as TX.
So if it should be green RX during receive and red TX during transmit, what does green TX mean? I'm now seeing 432mhz in the IF QRG field (changes when RX frequency is changed) and a green TX icon.
-
TX red = PTT active = FT-817 in TX mode
TX green = PTT not active = FT-817 in RX mode
If you press PTT on FT-817 color of TX icon changes from green to red.
-
TX red = PTT active = FT-817 in TX mode
TX green = PTT not active = FT-817 in RX mode
If you press PTT on FT-817 color of TX icon changes from green to red.
OK, I was confused because in your post #1 the icon was green RX (see attached), but I see you changed it to green TX in later versions.
Guess I will have to try another cable. In the meantime, I'll have to use my laptop and SDR Console, which has better audio and spots from DX cluster on the waterfall, but I'd prefer to keep my laptop free for work purposes.

Partial success today. I tried a third TTL/USB converter and finally the FT817 tx frequency changes when I change the rx frequency on the raspi!
The only issue now is that the icon does not turn red on transmit. I tried connecting TX GND to CTS, DSR, and DCD, none made any difference, icon stays green on TX. I even tried directly grounding CTR, DSR, and DCD, still no red icon. But this issue does not seem very important. The only thing that changes when the raspi detects that the FT817 is transmitting is that the speaker is muted or the volume is lowered, correct? I can live without that.
Odd that the icon always stayed red with one converter and now always stays green with the other.

Yes, thats correct.

What is this RS-232 is used for?
Is it possible to run it with other upconverters?

It controls and readout data from the up converter (power, temperature, voltage etc.). In the actual version you can control Kuhne MKU2424 and AMSAT UpCon6W converters.
