Hi all,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.
