Midland MXT115: Brief audio

[ladysmithgwl]

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.  I also thought that there may be some type of frequency "drift" causing the loss of audio on the MXT115.  All of the other radios were receiving fine and I programed the GMRS frequency into a scanner and the scanner received the HA1G just fine.  Just strange to me and something I have yet to resolve.  Anyone with a similar issue or ideas?

Separate the transmitting radio from the mxt115 radio by a greater distance and see if the problem continues. Your MXT115 might be desensing (going deaf temporarily because of a strong nearby signal.)

Sounds like a failing capacitor or Zener diode.

An issue with the Midland 115 radio is what I have pretty much concluded myself.  Threw this out there to see if anyone else may have experience this or had ideas which I hadn't considered.  Sounds like mine isn't the only one that has experienced issues.  Unfortunately my radio is long past the warranty period.  I have been thinking about a 40 watt radio for my truck.  Maybe now is a good time.

Thanks for the answer.  I did have them separated by about 500 feet.  Not a great distance but more than enough to me.  Of course when I figured out I was having a problem, I had them closer trying to diagnose and solve it.  I need them to work relatively close together because I use my handhelds with the mobile in my truck when I have my wife spotting me with backing our trailer.

500 feet certainly should have been enough.  In that case I have no idea what is causing the MXT115 to stop receiving after the first few seconds.  Is it only transmissions to the MXT115?  Are transmissions from it to other radios okay?

Yeap, all other radios are ok.  Very weird.  I thought it may be a Midland issue; but, the Midland GMRS handheld that I have receives without any issues.  A head scratcher to me.

I definitely think it is/was a 115 issue.  Went on a camping trip about a week ago and still had this radio in my truck.  I was on a camping trip and had repeater information programmed into the radio.  I was able to "trip" the repeater and receive just fine.  But, on the transmit side, there were audio issues with the radio.  Very brief audio and then drop.  Of course this is different than my very brief receive and then drop which started this thread.  Something weird going on with the audio on this radio.  I have since replaced it with a Radioddity DB-20G.  So far I am happy with the DB-20G.  I just have to find the sweet spot with the squelch setting.  I can go down to 2 and don't heard the static; however, after receiving a transmission sometimes the squelch remains "open".  Trying to go as low as possible to not adversely affect the reception range.
