Sorry, but have not been able to make the EXT Serial interface work with OmniRig.? At present, YCAT and the radio will talk nicely with each other.? Very frustrating because, at one time, YCAT, the radio and SDRConsloe were all three talking together.? Tomorrow, I'll try to replicate that and take notes on what I did.? Progress is sometimes elusive.
