How to fix Icom Transceiver when power does not come on?
If your Icom Transceiver's power isn't coming on, first, ensure the AC power cable is correctly connected. Then, check if the internal power supply is turned OFF and turn it ON. Also, inspect the circuit breaker; if it's tripped, identify the cause and reset it.
What to do if there is no sound from Icom Transceiver speaker?
If you're not getting any sound from your Icom Transceiver's speaker, first, check the volume level and rotate [AF] clockwise to increase it. If that doesn't work, ensure the squelch isn't closed by turning [SQL] to the 10 o’clock position. Also, make sure the transceiver is in receive mode by pushing [TRANSMIT] or checking the SEND line of any connected external unit.
Why is the received audio unclear on Icom Transceiver?
If the received audio on your Icom Transceiver is unclear or distorted, first, select a suitable operating mode. If the problem persists, reset the PBT function by pushing and holding [PBT-CLR] for 1 second. Also, turn the noise blanker OFF by pushing [NB], especially if you're receiving a strong signal. Deactivate the preamp by pushing [P.AMP] (MF3) once or twice. Finally, adjust the [NR] control for maximum readability if noise reduction is activated.
How to fix Icom Transceiver when output power is too low?
If you're experiencing low output power on your Icom Transceiver, rotate [RF PWR] clockwise. Also, adjust [DRIVE] and [MIC] to suitable positions. Ensure you've selected an antenna suitable for the operating frequency. If needed, manually tune the antenna by pushing and holding [TUNER] for 1 second.
How to fix unclear transmit signal on Icom Transceiver?
To resolve an unclear or distorted transmit signal on your Icom Transceiver, adjust [MIC] to a suitable position.
How to fix Icom Transceiver when displayed frequency does not change?
If the displayed frequency on your Icom Transceiver isn't changing properly, push [LOCK] to turn the dial lock function OFF. If the issue persists, reset the CPU.
How to increase sensitivity of Icom Transceiver?
To improve low sensitivity on your Icom Transceiver, start by reconnecting the antenna to the antenna connector. Ensure you've selected an antenna suitable for the operating frequency. If needed, manually tune the antenna by pushing and holding [TUNER] for 1 second. Lastly, check if the attenuator is activated and push [ATT] (MF4) to select “ATT OFF.”
What to do if no contact can be made with another station on Icom Transceiver?
If you can't make contact with another station using your Icom Transceiver, check if the RIT or ?TX function is activated and push [RIT] or [?TX] to turn them OFF. Also, verify if the split frequency function is activated and push [SPLIT] to turn it OFF.
Why repeater cannot be accessed on Icom Transceiver?
If you cannot access a repeater with your Icom Transceiver, activate the split frequency function by pushing [SPLIT] to turn it ON. If that doesn't work, reset the programmed subaudible tone frequency using set mode.
What to do if programmed scan does not stop on Icom Transceiver?
If the programmed scan on your Icom Transceiver doesn't stop, set [SQL] to the threshold point.
