What to do if my Icom Transceiver displays “NO POSITION” and “NO TIME”?
- J
  Jeremy RyanAug 12, 2025
  If your Icom Transceiver displays “NO POSITION” and “NO TIME” instead of the position and time, this could be due to a couple of reasons. First, the GPS signal might not be received correctly. Ensure that the GPS antenna connection is secure and properly positioned. Also, verify the NMEA input connection. Alternatively, the position and time may not have been manually entered. In this case, you should manually enter the position and time.

  If your Icom Transceiver does not turn on, there could be a bad connection to the power supply. Check the connection to both the transceiver and the power supply. Also, the fuse may be blown. If this is the case, repair the underlying problem and then replace the fuse.

Why does my Icom Transceiver have little or no sound?
- M
  Melissa HollandAug 20, 2025
  If you're getting little or no sound from the speaker of your Icom Transceiver, it might be because the squelch level is set too high. Try setting the squelch to the threshold point. Alternatively, the volume level may be set too low. Adjust the volume to a suitable level.

  Raven HuffmanAug 23, 2025
  If your Icom Transceiver displays “??” instead of the position and time, it could be because 23.5 hours have passed since you manually entered the position, or the GPS position is invalid. To resolve this, enter the current position and time.

  Jennifer LawsonAug 27, 2025
  If you cannot transmit with high power on your Icom Transceiver, it could be due to a couple of reasons. Some channels may be set for low power or receive only, according to regulations. Try changing channels. Alternatively, the output power may be set to low. Push the [HI/LO] button to select high power.
