I know this post is quite old; however, I was doing some research on MTX115 receive issues. I just purchased a couple of Ailunce HA1G radios. I was trying them out around the house and my MXT115 radio will receive the signal (indicated by the signal bars); however, I get the first couple of words of the transmission and then no other audio. I confirmed that there are no encoding tones set on the MTX115 and the Ailunce HA1G and there are none. I can receive on a Midland handheld, Baofeng handheld, and Retevis mobile without any issues. Just strange to me and something I have yet to resolve.
