Scott, I had assumed the Virtual Serial Port (VSP) into PSDR would be limited to just transporting the relevant CAT commands for TX and RX but, looking in Setup, it seems it can support PTT via the RTS line, which is what comes out of RemAud Server. Some more experimentation is called for next weeke...

Scott, Yes, the PC connected to the radio generates a hardware PTT signal which is configured in RemAud Server. Usual one-transistor interface, driven from (in my config.) pin 7 (RTS) off the D9F connector. Would be cool if this same functionality could be achieved over a Virtual Serrial Port pair, ...

Scott, Many thanks. My post does indeed sit better in this section of the board. I actually fixed my issue before I saw your reply. The part of the PSDR setup I was referring to in my initial post was in 'Setup - General - Hardware Config', not quite as I wrote:-( Within that tab, there is a 'Hardwa...

Hi all! Having a fun time trying to get my IRB working with a '7000 rather than a conventional transceiver at it's heart. It's 90% there, but I have one silly on the ANAN PTT and TX Audio. In outline, my setup is a PC in the shack running: 1. PowerSDR OpenHPSDR mRX v3.4.9, networked to the Anan, tak...
