What to do if Icom IC-R8500 power does not turn ON?

  Robert DeanSep 9, 2025
  First, ensure the DC power cable is securely connected. If that doesn't work, check for a blown fuse and replace it. When using an AC adapter, make sure the jumper connector is connected to the [DC13.8V] jack on the receiver's rear panel. If using an external 12 V DC, connect it to the [DC13.8V] jack, as the [DC IN] jack is only for the AC adapter (AD-55/A/V).

How to improve the sensitivity of my Icom Receiver?
- L
  Lisa SimpsonSep 1, 2025
  If the sensitivity of your Icom Receiver is low, check the following: 1. Ensure the coaxial cable isn't cut and fix it if it is. 2. Verify an antenna is connected. 3. Make sure the connected antenna is matched to the receiving frequency. 4. Check that you're using the correct antenna connector for V/UHF and HF antennas. 5. In set mode, confirm the proper antenna connector (SO-239 or phono (RCA)) is selected for the HF antenna. 6. Ensure an RF attenuator isn't activated by pushing [ATT 10 dB] or [ATT 20 dB] to cancel the function.
