Given that it is roughly a 3000 km path through the aurora zone between me and New England, I was surprised to see signals that good.

The RX is a modified Softrock Lite II with HDSDR processing the I/Q output and providing audio baseband. The audio is hard cabled to another soundcard which feeds WSJT-X and ARGO in parallel. The audio bandwidth is currently set for 3.5 kHz giving me a "tuning range" of 136 to 139.5. However HDSDR lets me "see" a spectrum from about 80 to 172 kHz, not that I can see much there besides switch mode power supplies!
