Has anyone gotten FLRIG or cocoa modem 2.0 to work with a Yaesu FT-991 on an iMac? I need one of them to transmit with the SSTV program MultiScan 3B, which doesn't have its own PTT feature. (I have my radio connected directly to my iMac via USB. I have FLDIGI and WSJT-X working fine.) I'm having problems using the PPT feature thru the USB Audio Codec? With FLRIG I just keep getting it to activate my 991's mic. I can't get cocoa modem to work at all. Thanks.
