Re: 440 Band Off Frequency
toggle quoted messageShow quoted text
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.
