Why is there no sound from my Icom IC-R8600 speaker?
If you are not hearing any sound from the speaker of your Icom Receiver, here are some things to check: * Make sure the audio level isn't too low or set to 0%. Increase the audio level. * Adjust the squelch level to open the squelch if it is set too tight. * Turn OFF the Tone or Digital squelch if either is ON. * Disconnect any headphones connected to [EX- SP] or [PHONES]. * Check the external speaker cable and repair it if disconnected.
Why is the sensitivity too low on my Icom Receiver?
If your Icom Receiver's sensitivity is too low, and you can only hear strong signals, try these solutions: * Turn OFF the attenuator in the FUNCTION screen. * Set [RF GAIN] to 100% to ensure it is not reduced. * Repair any defects with the antenna or coaxial cable and reconnect it to the antenna connector. * Connect an antenna suitable for the operating frequency. * Select the appropriate antenna connector. * Set the squelch level to open the squelch.
How to fix Icom Receiver when it does not power on?
If your Icom Receiver isn't powering on when you push the power button, check these potential causes: * Ensure the power cable is correctly reconnected. * Verify that the external power supply is turned ON. * If the DC power cable fuses or circuitry fuse is blown, find and repair the cause of the problem and then replace the damaged fuse with a new one. * If you're using the optional AD-55NS or SP-39AD, make sure the supplied DC power short connector is connected to [DC 13.8 V].
Why is SSB audio unclear on my Icom IC-R8600?
If the received audio in SSB mode is unclear or distorted on your Icom Receiver: * Try toggling between USB and LSB to select the correct sideband. * Touch [PBT1] or [PBT2] for 1 second to clear the settings if the Digital TWIN PBT function is activated.
