What to do if the displayed frequency does not change properly on Icom IC-910H?
If the displayed frequency on your Icom Transceiver does not change properly, it could be because the dial lock function is activated. Push [SPCH•LOCK] to turn the lock function OFF. If the issue persists, the internal CPU may have malfunctioned, and you should reset the CPU.
What to do if Icom IC-910H Transceiver received audio is distorted?
If the Icom Transceiver received audio is distorted, it could be due to several reasons. First, ensure you've selected the correct sideband (USB/LSB) by pushing [SSB/CW] for 1 second to switch between them. Secondly, if you are receiving an FM signal, push [FM] to select FM mode. Also, try turning off the noise blanker function by pushing [AFC/NB]. Finally, you can adjust the noise reduction level in the NR set mode using [SET] and [AFC/ NB•NR] for maximum readability, or turn OFF the function by pushing [AFC/NB•NR] for 1 second.
Why is the sensitivity low on my Icom IC-910H?
If your Icom Transceiver's sensitivity is low, start by ensuring the antenna is properly connected to the antenna connector. If it is, check whether the attenuator is activated and push [ATT] to turn it OFF. Another potential cause is the S-meter squelch being activated. In this case, rotate [RF/SQL] to the position where the noise just disappears.
How to fix no sound from the speaker on Icom IC-910H Transceiver?
If no sound comes from the speaker of your Icom Transceiver, there are several possible causes. First, check the volume level and rotate [AF] clockwise to increase it to a suitable listening level. Second, verify that the squelch is open by rotating [RF/SQL] to the 12 o’clock position. Finally, ensure the transceiver is not in transmitting condition by pushing [TRANSMIT] to receive, or check the SEND line of an external unit, if one is connected.
Why is the output power too low on my Icom IC-910H?
If your Icom Transceiver output power is too low, the first thing to check is the [RF PWR] setting. Rotate [RF PWR] clockwise to increase the power. Also, check the [MIC GAIN] and rotate [MIC GAIN] clockwise to increase it.
How to access a repeater with Icom IC-910H?
If you cannot access a repeater with your Icom Transceiver, first ensure that duplex operation is activated by pushing [SPLIT•DUP] for 1 second to turn duplex operation ON. If that doesn't work, check if a subaudible tone is needed and is activated. Push [TONE] to activate the subaudible tone or select a suitable tone frequency in the FM set mode using [SET] and [FM].
What to do if no contact possible with another station on Icom IC-910H Transceiver?
If you are unable to make contact with another station using your Icom Transceiver, it might be due to split frequency or duplex operation being activated. Push [SPLIT] momentarily or for 1 second to turn these functions OFF. Also, check if the RIT function is activated and push [RIT] to turn the RIT function OFF.
How to turn on Icom IC-910H Transceiver if power does not come on?
If the Icom Transceiver power does not come on when you push [POWER], it could be due to a couple of reasons. Check that the DC power cable is properly connected, and reconnect it correctly if necessary. Also, inspect the fuse, and if it's blown, identify the cause and replace it with a spare. Fuses are located in the DC power cable and the internal PA unit.
Why programmed scan does not start on Icom IC-910H?
If the programmed scan does not start on your Icom Transceiver, ensure that VFO mode is selected by pushing [V/M 1]. Also, if [RF/SQL] is assigned to RF gain and the squelch is open, reset the [RF/SQL] control assignment and set it to the threshold point.
Why memory scan does not start on Icom Transceiver?
If the memory scan does not start on your Icom Transceiver, first ensure that memory mode is selected by pushing [V/M 1]. If it still doesn't start, check that memory channels are programmed, and program desired frequencies into memory channels if they are not.
