Early on, I tried the delay you suggested Paul; adjusting it to see if there was a sweet spot, with no results.
Matthew, your interpretation of the manual is quite correct. If you send a command then read the buffer for a reply, there is none - the radio just does what it is supposed to. The only time there is something in the buffer is when you are looking at the Status Flags. Of course I have no working software for that.
For the record, the only code that worked was the exe made of QT/C++ that copied VFO-A to VFO-B. Any LabVIEW nor Python version worked - that is about a dozen different efforts.
Well, we beat a dead horse pretty well, didn’t we? I am thankful and honored you two put so much effort in trying to make this work. There is a positive out of this too. I learned some Python!
Thanks guys. Very much!
