Midland MXT400 to BTech GMRS V1



Hello. I am a bit of a 'new' GMRS user (Licensed: WRAM363). We've been using them for communication for our family fine with non DCS/CTCSS settings. However, I'm interested in expanding my knowledge/use for emergency preparedness, etc. I have a Midland MXT400 in my truck and one for home. I've got a few handhelds from Midland and Uniden for normal GMRS. I just got a Btech GMRS V1 as I am interested in extending range by using repeaters (and have permission from a few to test). One of the repeaters that I was given permission for uses DCS 125. I am a little perplexed by the DCS/CTCSS settings though. I figured I'd try a few things "locally" to test it out. Still not much luck. I set the two radios as below and can't seem to get them to talk. 






Midland MXT400 Setting: RPT 22 set on DCS 18 (which they say translates to 125 according to their manual)
Btech GMRS V1 Setting: RPT 22 set on Transmit and Receive for D122i which they say translates to 125...I’ve also so tried D125s with no luck
I've also tried using another repeater frequency/setup using CTCSS:





Midland MXT400 set to RPT 20 using PL code 141.3
Btech GMRS V1 set to the same
No luck Midland to BTech and vice versa.

Thank you for the reply KB2ZTX. After reading your reply, the light bulb went off around the TX/RX frequencies on the radios vs repeaters. When using a repeater channel on the Midland and BTech...it must go through a repeater to complete the TX Freq - RX Freq/TX Freq - RX Freq chain (Radio 1 OUT > Repeater IN/OUT > Radio 2 IN).


This guy, while not using GMRS frequencies, does a pretty nice job of explaining how a repeater functions.
