Adam,
Thanks for your answer. Do the P7100 and P7300 radios have the same battery and speaker/mic? The reason I'm asking is our company makes stakeout equipment for police that interfaces with a portable to send alarm messages. We do a lot of Motorola interfaces and Kenwood interfaces, but rarely Harris/MACOM. We have a dept. in NY that has a Harris XG-25P. They say it is a newer radio. We've never encountered that radio, but have done a MACOM P7100. But, I think they are different than the P7300 or XG-25P in both the speaker/mic and battery packs. I have all the wiring information for the P7100, but not for the XG-25P.
