I recently purchased a pair of Baofeng GM-15s and pleasantly surprised at the feel and quality, considering paying less than $60 for the pair. I will be heading off to an annual hunt and much of the group communicates via Garmin Rinos and a variety of Midland GPRS handhelds. I dug out an old GTX to find out if the two radios could play together. GM-15 to GTX, no problem. GTX to GM-15 no luck. I assume that is associated with the Midlands "Groups"(?) Is this something that can programed into the Baufeng so I can use these two new radios on the hunt and communicate with the other radios? Thanks, CJB
