Why does memory scan not start on Icom IC-7200?
Memory scan might not start on your Icom Transceiver if fewer than two memory channels have been programmed. Ensure that you program two or more memory channels.
Why is the Icom Transceiver sensitivity too low?
If the sensitivity of your Icom Transceiver is too low, and you can only hear strong signals, check that the antenna is properly connected (reconnect it to the antenna connector), the antenna feed line isn't cut or shorted (check the feed line and correct any issues), the antenna is properly tuned (push TUNER to manually tune the antenna), the attenuator function is off (push P.AMP to turn it OFF), and that you've selected the correct antenna for the operating frequency.
Why are my transmitted signals distorted on my Icom IC-7200?
Transmitted signals from your Icom Transceiver may be distorted if the microphone gain is set too high (adjust it to a suitable level in quick set mode) or if the compression level is too high when the speech compressor is ON (set the compression level to a suitable position).
Why is the receive signal distorted by strong signals on my Icom IC-7200?
If the receive signal on your Icom Transceiver is distorted by strong signals, it could be because the noise reduction is activated with a level that's too high (set the noise reduction level for maximum readability), the noise blanker function is activated (push NB to turn the function OFF), or the preamp is activated (push P.AMP to turn the function OFF).
Why Icom IC-7200 displayed frequency does not change properly?
If the displayed frequency on your Icom Transceiver isn't changing properly, it could be because the dial lock function is activated (deactivate it by pushing SPCH) or the internal CPU has malfunctioned (reset the CPU).
How to fix the frequency shift of the RIT function that cannot be added/subtracted in Icom IC-7200 Transceiver?
If the frequency shift of the RIT function cannot be added or subtracted on your Icom Transceiver, it might be because the XFC (transmit frequency check function) is turned ON. Turn the XFC OFF in the Set mode.
What causes distorted receive audio on an Icom IC-7200 Transceiver?
Distorted receive audio on your Icom Transceiver might be due to selecting an incorrect operating mode. Select a suitable operating mode.
What to do if receive signal is distorted by strong signals on Icom IC-7200 Transceiver?
If strong signals are distorting the received audio on your Icom Transceiver: * Adjust the noise reduction level for maximum readability, as the noise reduction might be ON and set too high. * Turn OFF the noise blanker function by pushing NB. * Turn OFF the preamp by pushing ATT.
Why is no contact possible with other stations on my Icom IC-7200 Transceiver?
If you cannot contact other stations using your Icom Transceiver, the RIT function might be activated (turn it OFF by pushing RIT), or the split function might be activated (turn it OFF by pushing SPLIT).
What to do if programmed scan does not start on Icom Transceiver?
If the programmed scan on your Icom Transceiver doesn't start, it might be because the same frequencies have been programmed in scan edge memory channels. To fix this, program different frequencies into the scan edge memory channels.
