OK, I see a pattern here. I have a Kenwood TS-690S and can NOT get HRD (v5) to communicate with my radio. I posted to HRD's forum several times asking for help and received no answers. After browsing this forum I see that I am not the only Kenwood owner that can't use HRD. Rather than asking why I can't get it to work, how about asking who has gotten it to work? I would be interested in knowing if there are any Kenwood owners that have successfully gotten HRD to work with their radios. Please let us know what radio you have and what you did, if anything out of the ordinary is required share that as well. So far I have found several posts indicating that the "TS-x50" series (the TS-690 is the TS-450 with 6 meters) has issues. Is there any way to get the software creator to respond to our questions?
