Re: Frequency calibration V5
|
So i picked up one of those NanoVNA¡¯s on amazon and it can generate a constant signal on any given frequency.? I¡¯m wondering how I can use that to set the BFO / calibration.??
Cory:
Unfortunately, the nanoVNAs are not accurate frequency generators, sometimes?as much as 10 kHz off.

I have yet to find a concise YouTube video or guide on how one actually knows when the BFO and calibration are both set correctly.
my guess is for BFO I¡¯m looking for the setting where the ¡°tone¡± generated by VNA goes away¡ª meaning the frequency on the dial is now sitting right on top of what would be the carrier.? But I could be completely wrong.
but seriously, the descriptions of ¡°zero beat¡± I read online don¡¯t click with me... ? this stuff is all just math... surely somebody can describe it that way.
