the noise is an INTERNAL noise generated by the VFO multipler or possibly the marker generator ...

unless is has the CB,........ err,.............. Mars mod and the band pass filters are 'effed up

Does indeed have the mars mod, but i have never transmitted there.
does nto have the TV mod.

how do bandpass filter break?
Why does this only happen on HF and not 12 meters and above?
I will also add i have noticed when i turn the radio on the external speaker makes an annoying POP sound, and when headphones are plugged in the POP is so loud you cant have the headphones on! the power supply is pushing a steady 14.3VDC. when i get home ill try the rig on a battery and shut all the power off in the house. This really sucks because i dont abuse or misuse this radio.

Okay just tryied it with headphones and it sounds much worse and it seems 20m shows the worse clipping. I also tried it on a battery and it still does it so I dont know what is up.

Before I do that, I have a cable since I use the radio via H.R.D. Can I back up my programmed frequency's some how ? I don't have any software and it would really help to get freeware....cause I have a feeling im going to be slapped in the face by icom with a huge repair bill.

Woa the reply woke me up. Let me try it right now. I did forget to unplug that cable.

Yes ! I unplugged it and the noise dissapeared. The cable also seems to add 2dBi noise on receive. So how do I remove noise from the cable ?
