Sussed! Faulty RS232 lead. It's a wee bit too short and the sharp 90 degree bend into the rig had caused pin 4 wire to come adrift.
My fault entirely but you guys have been very helpful since having had the software switches and set-up verified by at least six of you it had to be the hardware interface - 'when you have eliminated everything else whatever remains is the answer'. What is noticeable is the complete lack of EMC issues with serial port cw keying compared to the homebrew SO2R box which included the parallel port keying circuit and bucket loads of ferrites. I can now return those to the storage draws. Thanks and cheers, Terry G4MKP ....with Fw 2.23 loaded now! Thanks Dave G4AON. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
