Festival of Frequency Measurement 1 October 2019

Robert, VA3ROM

Thunder Bay Ontario Canada 48.452682 -89.20975 216 m ASL

At start of event SFI=68 A=14 K=2 and at end of event SFI=68 A=14 K=0.

File 1 created usging Fldigi 4.1.08 + PowerSDR (KE9NS version) + Flex-1500 SDR + GDPSDO + ground-mounted vertical (resonant on 30 m band).

File 2 created using Fldigi 4.1.08 + SDRuno + RSPduo (no GPSDO) + 80 m 1/4 wave sloping dipole orientated and sloping down from north (6 m AGL) to-south (1 M AGL).

Everything ran fully automatic so no problems encountered thanks to a couple of days of preparations to setup receivers, antennas and software and emergency backup power (just in case).

I was also able to record WWV's received dBm and SNR values with the SDRuno software if that data would be of any value to see how it would relate to frequency shifts of the time signal over time go hand--in-hand or not.
