    Why frequency cannot be set via the microphone on my Icom Transceiver?
    • C
      Curtis YoderAug 17, 2025
      If your Icom Transceiver's frequency cannot be set via the microphone, it might be due to several reasons. First, check if the frequency lock function is activated and deactivate it by pushing [SET(LOCK)] for 1 second. Another possibility is that the microphone keypad lock function is activated; you can deactivate it by pushing [FUNC] then [#(16KEY-L)]. Finally, the priority watch might be paused on the watching frequency; push [M/CALL(PRIO)] to cancel the watch.

    How to fix Icom Transceiver when no power comes on?
    • D
      Dan WashingtonAug 22, 2025
      If your Icom Transceiver is not powering on, there are a few potential causes. It could be due to a poor connection with the power connector; check the connector pins. Another possibility is reversed polarity in the power connection; re-connect the power cable, ensuring correct polarity. Finally, a blown fuse could be the culprit; replace the fuse if it is damaged.

    Why is the sensitivity low on my Icom Transceiver?
    • U
      uortizAug 25, 2025
      If you're experiencing low sensitivity on your Icom Transceiver and can only hear strong signals, the issue might stem from a poor contact or short circuit in the antenna feedline or antenna connector solder. Inspect these components and, if necessary, replace the feedline or re-solder the antenna connector. Alternatively, the squelch attenuator function could be activated. Adjust the [SQL] to a position between 10 and 12 o’clock.

    What to do if no sound comes from the speaker on Icom Transceiver?
    • M
      Mary WilsonAug 27, 2025
      If you cannot hear any sound from the speaker of your Icom Transceiver, there are several possible causes. First, check if the volume is too low and rotate [VOL] clockwise to increase it. Also, the audio mute function might be activated; push any switch or key to deactivate it. Another reason could be that the squelch is set too tight; set the squelch level to the threshold. Lastly, a selective call or squelch function, like pocket beep or tone squelch, may be activated; turn the appropriate function OFF.

    Why does scan not operate on Icom Transceiver?
    • E
      elizabethalvarezAug 30, 2025
      If your Icom Transceiver's scan function isn't working, there are a few things to check. Ensure the squelch is properly set to the threshold point, as an open squelch can prevent scanning. Also, verify that you have more than one memory channel programmed and that other channels are not set as skip channels; program additional channels or cancel the memory skip function on the desired channels. Finally, if priority watch is activated, cancel the watch to allow the scan function to operate.

    Why is no contact possible with another station on Icom Transceiver?
    • T
      Terry LopezSep 2, 2025
      If you're unable to make contact with another station using your Icom Transceiver, it could be because the other station is using tone squelch. In this case, turn the tone squelch function ON. Alternatively, your transceiver might be set to duplex; set it to simplex instead.

    Why does transmission automatically cut off on Icom Transceiver?
    • M
      Michael WalkerSep 5, 2025
      If your Icom Transceiver's transmission is automatically cutting off, it's likely that the time-out timer is activated. To resolve this, set the timer to OFF.

    What to do if transmission continues when PTT is released on Icom Transceiver?
    • M
      mburnsSep 8, 2025
      If your Icom Transceiver continues to transmit even after releasing the PTT button, the one-touch PTT function is likely activated. Turn the function OFF to stop continuous transmission.

    Why some memory channels cannot be selected via the microphone keypad on Icom Transceiver?
    • S
      sheenamillerSep 12, 2025
      If some memory channels cannot be selected via the microphone keypad on your Icom Transceiver, it is possible that the input channel number has not yet been programmed. Rotate the tuning dial to check whether the channel has been programmed or not.
