Why is transmitting impossible on my Icom Transceiver?
- KKimberly DurhamSep 8, 2025
If your Icom Transceiver is unable to transmit, ensure that the operating frequency is set to a ham band.
Why is transmitting impossible on my Icom Transceiver?
If your Icom Transceiver is unable to transmit, ensure that the operating frequency is set to a ham band.
Why doesn't the programmed scan stop on my Icom IC-7400?
If the programmed scan on your Icom Transceiver doesn't stop, it might be because the squelch is open. Set [RF/SQL] to the threshold point. Alternatively, [RF/SQL] might be assigned to RF gain control, also causing the squelch to remain open. In this case, reset the [RF/SQL] control assignment and set it to the threshold point.
Why doesn't programmed scan start on my Icom Transceiver?
If the programmed scan on your Icom Transceiver does not start, it could be because the same frequencies have been programmed in scan edge memory channels P1 and P2. Program different frequencies in scan edge memory channel P1 and P2.
Why doesn't memory scan start on my Icom IC-7400?
If the memory scan on your Icom Transceiver doesn't start, it's possible that fewer than two memory channels have been programmed. Ensure that you program more than two memory channels.
Why doesn't select memory scan start on my Icom IC-7400 Transceiver?
If the select memory scan on your Icom Transceiver does not start, it's likely that fewer than two memory channels have been designated as select channels. Designate more than two memory channels as select channels for the scan.
