If the operating frequency on your Icom Transceiver isn't changing when you rotate , the Dial Lock function is likely activated. To disable it, hold down to turn OFF the Dial Lock function.
What to do if Icom Transceiver repeater is busy?
If the repeater is busy, wait for a while, and then try again.
How to fix Icom Transceiver gateway repeater cannot be found?
If the Gateway Repeater cannot be found, check the Network settings.
What to do if my Icom IC-905 Transceiver connection is wrong?
If the transceiver connection is wrong, check the connection between the transceiver and the router.
What to do if the call sign has not been added to “Allowed Call Sign List” in the Icom IC-905 Transceiver?
If the call sign has not been added to “Allowed Call Sign List” in the transceiver, when “Allowed Call Sign” is set to “Enable,” you can either: * Set “Allowed Call Sign” to “Disable” in the INTERNAL GATEWAY SETTINGS screen. * Add the Remote D-STAR transceiver’s call sign to “Allowed Call Sign List” in the INTERNAL GATEWAY SETTINGS screen.
What to do if the Terminal/AP call sign that is set in the Icom IC-905 has not been registered in the RS-RP3C as the access point?
If the Terminal/AP call sign that is set in the transceiver has not been registered in the RS-RP3C as the access point, register the Terminal/AP call sign that is set in the transceiver in the RS-RP3C as the access point.
Why Icom Transceiver power does not turn ON?
The Icom Transceiver might not be turning on due to several reasons: the power cable might not be properly connected (reconnect the DC power cable correctly), the external power supply could be off (turn on the external power supply), or a DC power cable fuse might be blown (find and repair the cause, then replace the fuse).
What to do if there is no sound from Icom Transceiver speaker?
If you're not hearing any sound from the Icom Transceiver speaker, it could be due to a few reasons. The audio level might be too low, so rotate the control clockwise to increase the listening level. Alternatively, the squelch might be closed, so adjust the squelch level. In FM mode, the Tone Squelch function could be on, so turn it off. Lastly, in ATV mode, ensure that the “ATV Audio Sub Carrier Frequency” is set to something other than “OFF.”
Why is the sensitivity too low on my Icom Transceiver?
If the sensitivity of your Icom Transceiver is too low, and you're only picking up strong signals, it could be because the attenuator is activated (turn off the attenuator), the RF gain control is set too low (increase the RF gain until “RFG” disappears), you're using an unsuitable antenna (connect an antenna suitable for the operating band), or the squelch is closed (adjust the squelch level).
What to do if Icom Transceiver automatically switches to transmit while receiving?
If your Icom Transceiver is automatically switching to transmit while receiving, it could be due to the VOX function being enabled (disable the VOX function). Alternatively, the transceiver might be receiving a SEND signal from the software on your PC (confirm the “USB SEND” setting).
