I am 100' from my WSPR beacon, which is getting over 700 spots per day.
The instructions beautifully built the rtlsdr_wsprd
GQRX loudly hears both my WSPR beacon and the pico-cw-beacon in my attic attic, both on 10m
I calibrated the both transmit beacons with a pico frequency counter GPS standard fro vu3cer Dhiru Kholia (neat stuff)
https://github.com/kholia/pico-cw-beacon-drs
and

I have to believe that I have a calibration of the receiver step to add in. a 600 hz band is so terribly tiny. How may I confirm the crummy cheapest rtl-sdr is within a few Hz of correct?
