2200m Op32Rx Decodes (No correlation or deep search used!)
630m WSPR/FST4W
Grabbers are not active all of the time and will suffer interference when I am transmitting on LF.
The 2200m receiver is a modified SoftRock Lite II SDR kit. LO is injected at 408 kHz from a Leo Bodnar GPS reference clock and divided by four in the SoftRock quadrature clock generator. There is a 20 dB preamp with bandpass filtering before and after.
