Re: 440 Band Off Frequency

Dennis Klipa


I had this problem on one of my IC7000. We noticed that it was ever so slightly off frequency on HF.  It was usable on VHF but not UHF, but I didn't use it there.  Turns out the primary oscillator (not the right name but I can't think of it right now) was off frequency.  The amount it was off on HF and even VHF was small.  However, to get to 440, the main frequency gets multiplied several times and so does the error and my radio was way off on 440 just like yours.

I sent it in to Icom repair in Michigan.  Matt repaired it.  If it is off a little, it can be adjusted.  In my case he needed to replace something that wasn't cheap.  So if you don't use it on 440 you might not want to bother. I suggest you talk to Matt at SAR Technical Services,  269-429-2334.

Hi all,

I've a interesting problem with my 7000: Seems that the 440 MHz band, FM mode, has gone off frequency 5 kc low. In order for, say, 446.300 to have clear audio, the VFO needs to be at 446.305.  The problem is consistent on the 440 band.

This is not a problem on the 144 MHz band.

I've already performed the master reset procedure.

Any ideas?

All the best,
