I wonder if anyone has had any luck doing this. I have a ft-100 and 706mkIIG for radios. HRD will talk to each radio. I cannot get the second radio recognized by the program. would like to tune downlink with one radio and the uplink with the other radio using one instance of the HRD program. Any help or suggestions would be appreciated. Reply off list if you wish to do so. 73, Bruce ke0lx willmarbrowns@q.com
