Why won't the received call sign set to the operating call sign on my Icom ID-31A?
If, even when holding down, the received call sign will not set to the operating call sign on your Icom Transceiver, the call sign has not been correctly received. Try it again after the transceiver has again received its call sign.
What to do if the frequency cannot be set on Icom ID-31A?
If the frequency cannot be set on your Icom Transceiver, the Key Lock function may be activated. Hold down [LOCK] for 1 second to cancel it. Alternatively, the memory mode, Call channel mode, or DR mode may be selected; push [V/MHz] to select the VFO mode.
How to fix contacting problems with another station on Icom ID-31A?
If contacting another station is impossible on the Icom Transceiver, a different tone or code may be used for the tone/DTCS squelch. Check the tone/DTCS by performing a tone scan.
What to do if Icom ID-31A repeater does not transmit a reply after my call?
If the repeater does not transmit a reply after your call, it could be due to a wrong repeater setting. Ensure you set the correct repeater. Alternatively, the transceiver might be out of the repeater range, or your transmission isn't reaching the repeater. In this case, correct the repeater frequency, frequency offset, or duplex setting. You might also try accessing another repeater.
What to do if Icom Transceiver repeater replies ‘RX’ or ‘RPT?’ and the call sign of its gateway repeater after your call?
If the repeater replies with ‘RX’ or ‘RPT?’ and the call sign of its gateway repeater after your call, it may be because your MY call sign has not been set. In this case, set the MY call sign. Also, your own call sign might not be registered to the D-STAR Server, or it could be incorrect. Register your own call sign to the D-STAR Server, or confirm the registration of your own call sign. Finally, your calling station call sign might not be registered to the D-STAR Server, or it could be wrong. You should ask the server’s administrator about your calling station’s call sign.
Why doesn't a memory scan start on my Icom ID-31A?
If a memory scan does not start on the Icom Transceiver, the VFO mode or Call channel mode may be selected. Push [M/CALL] to select the memory mode. Also, only one or no memory channel may have been programmed; program two or more memory channels.
Why can't I transmit using the VOX function on my Icom ID-31A Transceiver?
If transmitting using the VOX function is impossible on your Icom Transceiver, the VOX Level may be set to OFF or too low. Set the VOX Level to a suitable level. Also, the MIC Gain may be too low; set the MIC Gain to a suitable level.
What causes the displayed frequency to be wrong on my Icom ID-31A?
If the displayed frequency is erroneous on your Icom Transceiver, the CPU may have malfunctioned, so reset the transceiver. Also, external factors may have caused a fault, so remove and reattach the battery pack/case.
What to do if Icom Transceiver repeater replies ‘UR?’ and its call sign after your call?
If the repeater replies ‘UR?’ and its call sign after your call, wait for a while, and try it again.
