I recommend the HRD support forum at http://forums.ham-radio.ch/.

The author of the program and several knowledgeable people are usually quick to respond.

The first thing they will ask you is the version and build of HRD you are using, and they will suggest you upgrade to the latest, if you have not already done so.

Good luck and 73, Bill NZ5N
