President Grant DX is staying in transmit mode even with microphone and cord unhooked from radio. It has the 999 board. When turning radio from off to on, it takes about a second then goes into transmit mode, also I can heard what sounds like a roger beep tone, which stays on continuously. Radio does show wattage output on the watt meter when hooked to it through antenna. What's your thoughts? Diode, transistor, roger beep circuitry? Has anyone ran into this issue before? Thanks for...
