A friend of mine just currently got a job with the local animal shelter as the dog warden and the 911 center wants you to talk to them on 39.90 mhz. He has a midland landmobile model 70-0375B commercial radio that will work but when attempting to transmit, it will for about a second and then stops and throws error code E3. I have a slight radio background but i have no idea about what the error codes mean or what to do to fix it. can some one please help??
