Hi, Dave.
Thanks, once again.? Bingo!? Everything is working now once I swapped out the RS-232 interface cable I had been using (first rig had only this typoe port for control and the PC had a real D25 serial port) but following your detailed instructions I removed that and now have a USB-A - USB-B cable between the radio and the Mac.? I even changed JS8Call and WSJT-X to use the flrig.rig as the "radio"and they both work as expected.
The only thing that I have still an issue with is that there is nothing appearing in the waterfall.? As seen in the screen snip, here I am monitoring Angelo, WA2UJR, who was coming in very strong.? I tried everything that came to mind to have a visible waterfall but no joy.? Any thoughts on what I'm missing?
Thanks once again.
Gary
