Is your HF rig Calibrated?
I was curious to know if what I was seeing on my HF radio display was what I was hearing
or when someone gives me a frequency would my radio be spot on?
we here is the answer: YES of course it is has a superhet.
but the other way is TUNE TO WWV 15.000 OR 10.000
this told me my radio was spot on.
for more information about this please
thanx so Ria N2RJ for more information on this. She is full of ham radio information
