What causes distorted transmitted signals on Icom IC-910H?
If transmitted signals from your Icom Transceiver are distorted, it's likely that the [MIC GAIN] is set too far clockwise. Adjust [MIC GAIN] to a suitable level.
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 no announcement when SPCH is pushed on Icom IC-910H?
If there is no announcement when [SPCH] is pushed on your Icom Transceiver, first check if the optional voice synthesizer unit, UT-102, has been installed, and install it if it hasn't. If installed, ensure the announcement level is set to a suitable level in the SPCH set mode using [SET] and [SPCH]. Finally, verify that the announcement language is set to “Eng” (or JPn) in the SPCH set mode using [SET] and [SPCH], and change it if it's set to “oFF.”
Why no sound from my Icom IC-910H speaker?
If no sound is coming from the Icom Transceiver's speaker, first, ensure that the volume level isn't too low by rotating [AF] clockwise to a suitable listening level. Also, check if the squelch is closed and rotate [RF/SQL] to the 12 o’clock position to open it. Finally, verify that the transceiver is not in transmitting mode by pushing [TRANSMIT] to receive, or check the SEND line of an external unit.
