Why is Icom Transceiver transmit signal distorted?
- PPatrick DuarteSep 10, 2025
If your Icom Transceiver transmit signal is unclear or distorted, the [MIC] might be set too far clockwise. Adjust [MIC] to a suitable position.
Why is Icom Transceiver transmit signal distorted?
If your Icom Transceiver transmit signal is unclear or distorted, the [MIC] might be set too far clockwise. Adjust [MIC] to a suitable position.
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.'
Why is Icom IC-7800 Transceiver received audio unclear?
If the received audio on your Icom Transceiver is unclear or distorted, consider these possible causes: the wrong operating mode might be selected, so choose a suitable one. The PBT function might be activated, so push [PBT CLR] for 1 second to reset it. If you're receiving a strong signal, the noise blanker might be on, so push [NB] to turn it OFF. Also, the preamp might be activated, so push [P.AMP] once or twice to turn it OFF. Finally, if the noise reduction is activated, adjust the [NR] control for maximum readability.
How to fix Icom IC-7800 when power does not come on?
If the power doesn't come on when you push the power switch on your Icom Transceiver, there might be a few reasons. First, check that the AC power cable is correctly connected. Next, ensure that the internal power supply is turned ON. Finally, if the circuit breaker is tripped, identify the cause and then reset it.
What to do if no sound from Icom IC-7800 speaker?
If you can't hear any sound from the speaker of your Icom Transceiver, there are a few potential causes. First, the volume level might be too low, so rotate the [AF] control clockwise to increase it. Second, the squelch might be closed; turn the [SQL] to the 10 o’clock position to open it. Lastly, the transceiver might be in transmitting condition; push [TRANSMIT] to receive, or check the SEND line of an external unit if one is connected.
What to do if programmed scan does not stop on Icom Transceiver?
If your Icom Transceiver's programmed scan doesn't stop, set [SQL] to the threshold point.
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.
