I got two new pairs of GXT800 in April and already two of them will not tx or rx,this is an intermitant problem.has anybody had the same problem?

It is very unusual, but not completely out of the question, that this problem would be due to a defect. Most of the time when we hear of problems like this it is due to radio settings. First, you should double check that both radios are set to the same channel and privacy code, and that group mode is off (unless you are specifically trying to use group mode).

If you’ve double checked everything and you are still having problems, you’ll have to send the radios in to Midland for repair or replacement. You’re in luck though, Midland has the best warranty (3 years) in the consumer radio business and they are very easy to work with.
