Hi Glenn,
Your config looks like a mix of the old RIGCONTROL style with the newer RADIO style. Per choose one OR the other method but not both.
If you prefer the older RIGCONTROL method it may be as simple as removing the "RADIO 1" from within your port definition. Personally I would also move the BW500 just before or after the SESSIONTIMELIMIT rather than after the **** terminator for the RIGCONTROL section.
To use the newer method remove the RIGCONTROL statement and create a new RADIO 1 block outside of the port definition. Move all of the rig timing and scan parameters into the new RADIO 1 block and terminate this new block with "****". The end result should be a global RADIO 1 block that is referenced within the config section of your VARA port with the RADIO 1 that you already have there.
I hope that helps...
