Guest nodoze Posted February 26 Report Share Posted February 26 Between the BTECH AMP-U25 & AMP-U25D amplifiers which is better for the For GMRS-PRO? In reading this reddit thread it sounds like the data is APRS compatible: Does using APRS mean you need the AMP-U25D (digital version)? If price isn't a consideration, any thoughts as to which is better to go with (AMP-U25 or AMP-U25D)? I do like that AMP-U25 has "Out-of-Band Transmit (Pass-through the HT's power to the external antenna while amp is powered off)" but to get that it sounds like you have to give up "DMR and P25 Phase 2 modes" which I don't know if the GRMS-PRO needs those...
