Why the [ANT] switch does not function on Icom Transceiver?
If the [ANT] switch on your Icom Transceiver isn't functioning, make sure the antenna switch in set mode is set to 'Auto' or 'Manual'.
What to do if no sounds come out from the Icom Transceiver speaker?
If you can't hear any sound from the Icom Transceiver speaker, try these steps: First, rotate the [AF] knob clockwise to increase the volume. Next, adjust the squelch by turning [SQL] to the 10 o’clock position to open it. Lastly, ensure the transceiver isn't in transmitting mode by pushing [TRANSMIT] to receive, or check the SEND line of any connected external unit.
Why is received audio unclear or distorted on my Icom IC-7800?
To troubleshoot unclear or distorted received audio on your Icom Transceiver, try the following: Ensure you've selected the correct operating mode. If the PBT function is activated, push [PBT CLR] for 1 second to reset it. If you're receiving a strong signal, turn OFF the noise blanker by pushing [NB]. Deactivate the preamp by pushing [P.AMP] once or twice. Finally, adjust the [NR] control for maximum readability if the noise reduction is activated.
How to fix Icom IC-7800 if output power is too low?
If the output power of your Icom Transceiver is too low, try these solutions: Rotate [RF PWR] clockwise. Adjust [DRIVE] to a suitable position. Also, set [MIC] to a suitable position. Ensure you've selected an antenna suitable for the operating frequency. Finally, manually tune the antenna by pushing [TUNER] for 1 second.
Why is the sensitivity too low on my Icom IC-7800?
If the sensitivity of your Icom Transceiver is too low, and only strong signals are audible, try these solutions: Ensure the antenna is properly connected to the antenna connector. Select an antenna suitable for the operating frequency. Manually tune the antenna by pushing [TUNER] for 1 second. Finally, deactivate the attenuator by pushing [ATT] several times to select 'ATT OFF.'
What to do if no contact possible with another station on Icom IC-7800?
If you can't make contact with another station using your Icom Transceiver, it might be due to the RIT or ?TX function being activated. Push [RIT] or [?TX] to turn these functions OFF. Also, check if the split frequency function and/or dualwatch are activated; if so, push [SPLIT] and/or [DUALWATCH] to turn them OFF.
Why is the transmit signal unclear or distorted on my Icom IC-7800 Transceiver?
If your transmit signal is unclear or distorted on your Icom Transceiver, adjust [MIC] to a suitable position, ensuring it is not set too far clockwise.
Why doesn't frequency change on Icom Transceiver?
If the displayed frequency on your Icom Transceiver doesn't change properly, it could be due to a few reasons. The dial lock function might be activated; push [LOCK] to turn it OFF. A set mode screen might be selected; push [EXIT/SET] several times to exit the set mode screen. The internal CPU may have malfunctioned; try resetting the CPU.
Why does the displayed frequency not change properly on my Icom IC-7800 Transceiver?
If your Icom Transceiver's displayed frequency isn't changing properly, here's what to check: * Push [LOCK] to turn the function OFF if the dial lock function is activated. * Push [EXIT/SET] several times to exit the set mode screen if a set mode screen is selected. * Reset the CPU if the internal CPU has malfunctioned.
Why repeater cannot be accessed on my Icom IC-7800 Transceiver?
If you are unable to access a repeater with your Icom Transceiver, ensure the split frequency function is activated by pushing [SPLIT] to turn it ON. Also, check if the programmed subaudible tone frequency is wrong and reset it using set mode.
