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,

The IC-7000 oscillator is very temperature dependent.
You have to re-adjust the reference frequency in the OTHER menu
when temperature changes a lot and causes frequency drift
in the higher frequency ranges, especially VHF and UHF.
Find a commercial station in the VHF or UHF,
tune in SSB with an offset of 500 Hz and adjust
the difference tone to 500 Hz using a smartphone app.
Im am using the app "Spectroid", but there are many others.
Alternatively you could use a guitar tuner at 440 Hz.
If the frequency iy stored in memory, the whole procedure
takes less than a minute.
