Why does Icom IC-208H transmission continue even when the PTT is released?
If the transmission continues even when the PTT is released on your Icom Transceiver, the one-touch PTT function may be activated (turn the function OFF).
Why some memory channels cannot be selected via the tuning dial on Icom Transceiver?
If some memory channels cannot be selected via the tuning dial on your Icom Transceiver, the memory channel number may not have been programmed yet. Select the channel via the microphone keypad to check whether the channel has been programmed or not.
