Kenwood tk-8160H-K, 450-490Mhz, programmed to the GMRS frequencies. It won't transmit but will receive. When push the PTT the radio displays Kenwood and resets to the channel display. I have it powered directly to the battery (fused) and I still cannot transmit. When I push the PTT the radio briefly displays Kenwood and resets to the channel display. Suggestions are welcomed, thank you.
