I'm still kinda puzzled by his comment about "software can change a FRS radio to Wideband". I guess that is possible through the Microphone and charging jack port but is there software out there for the Midland LXT600 series FRS radio so that can be done? Maybe Chirp actually can get into a Midland LXT600 radio and change the deviation on that radio to wideband? I'm not a Chirp guy and I will never have a need for the Chirp software and a radio that is programmed with Chirp.
Oh well, moving on and wishing I was packing the Jeep for a run. The Jeep clubs I belong to make their runs on Tuesdays, Wednesdays, and Fridays and never during a weekend and there is nothing this week I believe there is something scheduled for the following week. Enjoy your weekend run
Literally all factory FRS radios are fixed and not programable. FRS channels are 12.5 KHz from channel 8 through 14, the rest are 20 KHz.
Those LXT600s are decent radios but not programable and comliant with FRS rules.
Baofeng and anytone can be programmed, but they don't comply with part 90. A lot of people use them thogh.
Broken audio can be a lot of things especially antennas or connections. I doubt it is your XTL.
I presume also you know there is a limit of 50 watts to be legal on GMRS, and that is channels 15 and up. Problem running 100 watts, is people are going to hear you but not enough power to talk to you. (I know, people will do it anyway)
Check all your connections/antenna, have you group do the same and have a fun runnabout.
