Thank you so much for anwsering. I'm aware of the scanning feature on both radios. I was attempting to make them work on the lower channels. Niether radio was in scan mode. I am also aware of the fact that the Tera has no FRS frequencies. I removed all the privacy codes on the tera with the programming software. I turned the privacy codes off on the Midland as well. If I turn the radios on when on the same freq. I can transmit with the Tera to the Midland no problem. If I then turn the radios to a different freq. I can no longer transmit first with the Tera. I must transmit 1st with the Midland and then I can transmit fine with the Tera. Now when the radios have had the frequencies changed and I try to transmit with the Tera, the Midland does not show show RX on the screen. I can hear a hum from the Midland, but no sound and no RX is present. I guess this must be something simple, but for the life of me I can't get my head around the problem.Please, if you read the post, give me your ideas and I'll try them out in hopes of finding the solution. Thanks again for your help.
