CAT PTT does not allow MIC-2 to be used for Maestro w SO2R SSB?

I had nothing but problems with Foot Switch PTT using the FTDI chipset cables to the PC and I tried a bunch of them, I had a Prolific chipset cable in my USB Comport box and have ran it for about a year now with ZERO problems being used for my Local PTT switch or Foot switch.

The USB Prolific cable will NOT work on the Radio's USB port so you may want to label it to keep it separated

I think that the REAL FTDI chipset cables RTS/DTS has lost something in the past few years that Real COM ports use for Modem support I think it is the Correct pull up voltage / Current.

Hi Kari, i try to do the same with but with smartsdr not maestro, the result is that the MOX is blue while pressing footswitch (over FTDI USB2serial) no TX power but you can see audio level-compression moving so the audio reaching radio but no power out. Typical one of three times TXing while pressing foot switch. Running latest 3.1.12

Just received my new 6600M model and want to use my B model Maestro with it remotely like I did with the old 6400M. CW works fine but no SSB. Can't select a mic. It jumps around when I'm trying to select "M-Line".
