Here in the UK the MF AM broadcasting stations have a very tight

tolerance regarding transmission frequencies. This is due to multiple
re-use of the same frequencies and the need to avoid heterodynes.
Do you have a strong local station to use as an accurate frequency source?

Is there any way to use something like a function generator to calibrate
the REF adjust on my IC-7000 without having to tune to WWV? I have a 10m
dipole on my roof and can't get the WWV signal at all. I have been
playing with WSPR and PSK31 and was just reading my manual again. There
isn't a lot of info under REF adjust and I was wondering if someone can
help me understand what is going on a bit better.
I can see wanting to zero beat WWV in the field, but didn't know if
there was some way of accomplishing the same thing with a function
generator, oscilloscope, and spectrum analyzer in a basement? :)
