Hi, first time poster. Took my Midland FRS GXT-1000P and tried twice with its "preset channels" (23-50) to talk to my BTech GMRS-V1 using both CTCSS and DCS. I programmed my BTech with what Midland told me to do (using same code for both Rx and Tx per BTech's instructions) and nothing. Devices work fine without privacy codes when in channels 22 and below. Apologies if this has been covered previously and/or multiple times before. And, yes, as one website suggested, I tried it with privacy codes 38 and under.
