|Results 630m WSPR RX till now.|
I attended a clubmeeting lately were PA2DTA showed some kind of direction finding receiver. It was capable of receiving in what I think the medium wave range. One of the things he showed was the difference between a attached longwire and a small dipole made with windings on a ferrite rod. I have to admit the dipole received a lot better as it didn't receive electric noise. However it was directional and that is nice to track a station but isn't when receiving WSPR signals around you.
Would I receive WSPR signals on 474,2KHz? Yes, not as many but I did! I think this design could be much better as just a single wire outside the house. Thinking of a bigger loop outside the house. The only problem is the directivity. If you call it a problem of course as you are able to null out the QRM/QRN. It would be nice to experiment with it in the future. It also shows that you are able to pull WSPR signals out of the noise with a simple antenna inside the house on the 630m band.
