the IF QRG box just has a "?", it no longer shows 432mhz.
"?" in the IF QRG field means that there is no communication to FT-817.

Hi,
in Post #200 , your converter is a silicon labs 2102, in post #206 it's a prolific. Are you sure you have checked the prolific with sdr-console or did you only verify that the silicon labs is working? Try the silicon labs under linux as well as the prolific under windows just to be sure.
-
Working fine with SDR Console, maybe the CT-62 CAT cable is not Linux compatible?
You use the Yaesu CT-62 USB CAT cable? In this case the PTT detection will not work because the TX GND signal is not connected internal.
So you have to use USB/TTL-converter with TX GND connected as described.
-

Yes, that was my error, I had changed the baud rate. When I set it back to 4800 the 432mhz reappeared in the IF QRG field, and the icon changed back to red TX. But the FT817 was not actually in transmit mode.

The converter in post #200 did not work with either the raspi or SDR Console on windows laptop. I changed cables, and the converter in post #206 works fine with SDR console but is not working with the raspi. There is apparently some type of communication, because I'm seeing 432mhz in the IF QRG field and a red TX icon. But the raspi is not changing the frequency on the FT817 and, even though the red TX icon means the FT817 is in transmit mode, it actually is in receive mode.

With the Yaesu CT-62 USB CAT cable? Then the TX detection will not work (see #214 obove).

Yes, I changed to a Yaesu CT-62 USB CAT cable. It just does not work with PTT? It should work to control the TX frequency on the FT817? It is not doing any control at all.
Previously, I used the USB/TTL converter in post #192, which also did not work.
-
During TX (if the TX icon is red) there will be no frequency updates.
That makes sense. Is there a way to stop the TX icon from going red? Maybe the pin that needs to be connected to TX GND is somehow permanently grounded, which would cause the raspi to think the FT817 is transmitting.
-
Try to desolder the wire TX GND and see what happens.

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.
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?
