In somewhat of a pickle in trying to decide which Midland GMRS mobile radio set to go with. I like the MXT400 as it has a stated 40 watts of power. The MXT275 rings my bell because it is so small it can be easily mounted almost anywhere and all the controls are on the mic, but it has an advertised 15 watts of power. Not being an expert on these small mobile units, I'm not sure how much of a difference 25 watts of power between the two will make. I have used CB radios on long car trips between vehicles before and found them to be very handy. I'm expecting a bit more trans/recv distance with the GMRS radios and would like to get the most I can out of them. Hoping someone with a lot more experience with these type of radios can tell me which will give me more bang for my buck. Tks.
