Why transmitting is impossible on Icom IC-910H?
If transmitting is impossible on your Icom Transceiver, the PTT lock function may be activated. Turn the PTT lock function OFF in the TRANSMIT set mode using [SET] and [TRANSMIT].
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.
What to do if no announcement when SPCH is pushed on Icom IC-910H?
If there is no announcement when [SPCH] is pushed on your Icom Transceiver, first, ensure that the optional voice synthesizer unit, UT-102, has been installed. Also, check that the announcement level is set to a suitable level in the SPCH set mode using [SET] and [SPCH], and that the announcement language is set to “Eng” (or JPn) in the SPCH set mode using [SET] and [SPCH].
What to do if memory scan does not start on Icom IC-910H Transceiver?
If the memory scan on your Icom Transceiver does not start, ensure that memory mode is selected by pushing [V/M 1]. Also, check if any memory channels are programmed and program the desired frequencies into memory channels.
Why mode select scan does not start on Icom IC-910H?
If the mode select scan on your Icom Transceiver does not start, ensure that mode select scan mode has been selected by pushing [SPCH•LOCK] for 1 second on the desired operating mode programmed channel. Also, program more than two channels with the desired operating mode, if only one channel is programmed with the selected operating mode.
How to start mode select scan on Icom Transceiver?
If the mode select scan does not start on your Icom Transceiver, first ensure that mode select scan mode has been selected by pushing [SPCH•LOCK] for 1 second on the desired operating mode programmed channel. Also, make sure that more than two channels are programmed with the desired operating mode; if not, program additional channels.
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.
