I followed the WSPR doc instructions on my orange Pi PC2 running Armbian.
I plugged in a RTL-SDR.com version 3 dongle and attached the antenna connection to my 3 foot high 8 Wire Discone antenna.
10 minutes later I was picking up a WSPR signal from Alice Springs Australia. Like 3000 km away from Philipines.
I was stunned. But I checked on the WSPR net website and there was the confirming line on the map stretching from Australia to Philippines.
My question is does these instructions which allow for Q mode (basically a underclocking of the dongle) only apply to the generation 3 RTL-SDR dongle with a TXCO crystal or can I use a $9 Blue rtl dongle from China and use the PPM correction (-52 in my case) to correct the frequency.
