What to do if no sounds come from the Icom Transceiver speaker?
If you're not getting any sound from your Icom Transceiver's speaker, check the following: the volume level may be too low (rotate [AF] clockwise), the squelch might be closed (rotate [RF/SQL] to around the 10 o’clock position to open it properly), or the transceiver could be in transmitting mode (turn off the transmit mode).
Why doesn't programmed scan start on my Icom Transceiver?
Programmed scan may not start on your Icom Transceiver if the same frequencies have been entered in scan edge memory channels P1 and P2. To fix this, enter different frequencies in Scan Edge memory channels P1 and P2.
Why doesn't memory scan start on my Icom IC-718 Transceiver?
Memory scan won't start on your Icom Transceiver if fewer than two memory channels have been entered. Make sure to enter two or more memory channels.
What to do if the displayed frequency does not change when rotating the main dial on Icom IC-718?
If the displayed frequency on your Icom Transceiver doesn't change when rotating the main dial, it could be due to the dial lock function being activated (push [LOCK] to deactivate it), a Quick Set mode screen being selected (push [SET] to exit the Quick Set mode), or the internal CPU malfunctioning (reset the CPU).
Why is it impossible to transmit with my Icom IC-718?
Transmitting may be impossible with your Icom Transceiver if the operating frequency is outside the selected ham band. To resolve this, set the frequency within the selected ham band.
Why is receive audio distorted on my Icom IC-718?
Distorted receive audio on your Icom Transceiver can be caused by several factors: * The operating mode is not selected correctly (select the correct operating mode). * The IF SHIFT function is activated (rotate SHIFT to the center position). * The Noise blanker function is activated (push [NB] to turn OFF the function). * The preamp is activated (push [P.AMP] to turn OFF the function). * If installed, the Noise Reduction function is activated and the [NR] control is set too high (set the [NR] control for maximum readability).
Why is the output power too low on my Icom IC-718 Transceiver?
If the output power of your Icom Transceiver is too low, it could be due to several factors: the [RF POWER] may be set too low, so adjust it to a suitable position. Also, the [MIC GAIN] might be set too low, so adjust that as well. Ensure you have selected an antenna suitable for the operating frequency and that the antenna is properly tuned by pushing [TUNE] for 2 seconds to manually tune it.
Why are transmitted signals distorted on my Icom Transceiver?
Distorted transmitted signals from your Icom Transceiver may be due to the [MIC GAIN] being set too high; adjust it to a suitable position. Also, the [COMP] function may be activated; turn it OFF.
Why is transmitting impossible on my Icom Transceiver?
If transmitting is impossible with your Icom Transceiver, ensure that the operating frequency is set to a ham band.
How to resolve distorted transmitted signals on my Icom IC-718 Transceiver?
If the transmitted signals from your Icom Transceiver are distorted, first, check the [MIC GAIN] and set it to a suitable position. If the [COMP] function is activated, turn it off.
