Newbie here, first post actually! I picked up one of these radios recently and have noticed a couple things. 1) The GMRS-V1 starts with channel 0 instead of 1 so if you are using this radio with your more typical GMRS radios like Cobra, Motorola etc. your channel numbers are all off by 1 channel, i.e Ch. 1 on a Motorola is actually Ch. 0 on the V1. I'm hoping this can be reprogrammed with CHIRP but haven't tried it yet. 2) The scanning function for CTCSS tones doesn't work very well, or I'm doing it wrong. I suggest having a printout of the CTCSS tones of whatever other radio you are trying to communicate with as there isn't a standard it appears across the many consumer GMRS units. Obviously if you are using the V1 with another V1, neither of these issues matter, nor are they deal breakers when using with units for other manufacturers, just something to be aware of should you purchase a V1.
