Greetings from Idaho. My name is Steve Galbraith . My callsign is KB7ITU. I am one of 6 digital trainers for the area. We use the digital modes for emergency communications. I knew that the digirig was beginning to get popular so decided i should buy one and learn how to help others set it up. What a breeze. In 10 minutes I had it working with my kenwood ht and in another 10 minutes I had it woking on my kenwood tm-v71a. If you are going to use it on VARA FM you will need , in some cases to cutt the trace between the two pads marked att. The audio is a little too high for that mode. Once I cut the trace it worked with no problem. What a great product and price.
