A 40m WSPR weekend

40m from 7am-7pm local time
With the Solar cycle heading on a downward trend I have been reading how 40, 80 and 160m may be the bands of choice for QSO's. Since my MFJ 1788 will only venture down to 40m and at the best of times I have found it to preform like a wet noodle on this band. I decided this weekend to give WSPR a go on 40m using 1 watt to see what results I got. My 1 watt signal was picked up throughout Canada and the U.S. There was a one off to Spain but the consensus from WSRP.net was on 40m my DX was going to be North America. There was one odd report which repeated itself over and over, it was from WY1R saying he was hearing me on 6m?? Not to sure what that was all about. I also was checking with PSK reporter looking at WSPR mode and funny thing was there was never any hits for my call?

    Hi Mike,
    That’s a great indicator of 40 m daytime skip. A big band up through the centre of the country where you weren’t heard. You could be heard in California but Not Wyoming, North or South Dakota, Colorado, Nebraska, etc.
    Spain was a good catch.

    30 m should give you some more dx especially around sunrise and sunset. 160 m over here has been doing well.

    Good evening Ron, I plan to give 30m a go this weekend for some dawn and sunset feedback.

    You don’t need a whole watt for wspr! With my 10mW output from a Raspberry Pi on 60m (5MHz) I have been reported recently as heard 2000+km away in OH, and also in LA, TF and OY (all over 1000km). The antenna is a simple 20 metre long wire fed by a Wimo UNUN “magnetic balun”. BTW I used a LPF kit from hans summers.

    hope to see you qrpp!

    Good evening Andy, in the past I have used mW power but this time I was using my balcony mounted MFJ 1788 that at the best of times is very poor on 40m. I used 1 watt to see if the loop would preform over the top.
