Hi jmcconomy, The GMRS V-1 is a nice radio. I have one and use it often. To program the radio using chip is not hard once you understand what info goes where. I will try to explain it so I don't confuse you. For example using a repeater on channel 18. If the input is 467..625, the output is 462.625. If you have a PL tone of 555.5 (not a real tone, just used as an example) , here is what you would enter in chirp. Repeater channel 18 for the GMRS V-1 is line #18 in chirp. Frequency = 462.625 Tone Mode = TSQL Tone & Tone Sql = 555.5 ( enter actual tone from MyGMRS.com) Cross Mode = Tone-Tone That should get your repeater channel programmed in. If you have any other questions, I will try to answer them Hope this helps and enjoy your radio.
