Web SDR can be very attractive because of monitoring some bands. The University of Eindhoven has two receivers online with the following bands: 80 m, 40 m, 6 m, 4 m and 2 meter. I can check easily if there is any propagation on e.g. 6 meter. I don’t have to search myself, just in one view I check the waterfall of the web SDR. I compared my antenna and receiver with the receiver and antenna of the University of Eindhoven, using WSPR on 40 meter. A good station to watch is DL6NL which is transmitting on 40 meter with 50 mW. I was using an end fed wire as sloper, and the University of Eindhoven a multiband vertical. Eindhoven received him with -23 dB. I received him with -24 dB. I live 100 km further away than Eindhoven. Conclusion: my receiving capability is OK with the end fed wire for 40 meter.
