Why doesn't programmed scan start on my Icom IC-7000?
If the programmed scan on your Icom Transceiver does not start, it is possible that the same frequencies have been programmed in scan edge memory channels. Program different frequencies into scan edge memory channels.
Why won't the memory scan start on my Icom IC-7000 Transceiver?
If the memory scan on your Icom Transceiver does not start, ensure that you have programmed 2 or more memory channels.
