I've recently become interested in Digital Modes on 2 meters. (Trying to communicate with my son 8 miles away .. HF NVIS has been problematic). I tried to find some cheap SSB 2 meter rigs to test the

I saw a thread a week ago or so about the gps lock on the UB4. I made a 45mm dipole with a 25mm twisted feed line and have the unit outside with a good view of the sky. I am not getting any Sat data a

I've seen this covered in past threads but this instance has to do with a rig that's been working for almost a year. Went to activate a park, and the headphone audio was crackling as soon as I powered

Just received my QCX-mini (20m) kit. It came with the microcontroller labeled T1.09, but I see the current firmware is T1.09a. The Firmware History indicates the “a” rev only effects 160m operation. I
