This weekend the CQ World Wide 160-Meter Contest was held. I do not participate in CW contests but it was a good chance to listen to it using my new toy, the Airspy R2 and the Spyverter HF converter. Also with SDR you can have a nice view of what is going on in the band.
The screenshot shows 1810 to 1870 kHz and that part is very crowded. Also the huge differences in signal strength can be seen. The reception with this combo is very good, filters can be set very narrow and in this way almost all stations can be heard without interference from nearby stations.
