Last night I setup the FT847 on 144.370 which is the FSK441 frequency and set the WSJT software running in monitor mode to see what would happen. When I looked at the 'log' this morning there was plenty of interest and quite a number of stations heard:
PA0BWL (tropo or backscatter?)
EA3AXV (one of the outstanding signals for me - copied many times)
S50C (another outstanding and consistent signal)
YO2LAM (probably the best DX)
PA5KM (tropo or backscatter)
Well, I probably should have spent some time trying to make some QSOs, but actually I was quite happy to see what I heard and I am delighted with this haul. The antenna here is just the little 5 element, so this was probably more about strong short reflections rather than longer but quite weak ones that you get when you aim closer to the horizon with a long yagi.
It's not all over yet though and it will probably be worth setting the receiver going again this evening.
