10m WSPR yesterday
10m unique WSPR spots yesterday |
Quite a productive day on 10m yesterday with both Es and F-layer DX about. Best DX spot of my 2W was from FR1GZ on Reunion Is. and my best spot was of CX2ABP (11127km) in Montevideo, S.America who uses 5W.
This morning I have returned to 6m but G4IKZ, my faithful local reporter is not on!
Sunspots and HF conditions
Today the sunspot count is 155 (good) but 20-30MHz conditions are expected to be poor. Mind you they were meant to be poor yesterday yet CX2ABP was a decent signal on 10m WSPR last evening.
So far this morning 6m has been disappointing with just locals spotting me and no Es seen, as yet. It was quiet on 6m yesterday , which was why I spent most of the day on 10m.
We are now in basically summertime conditions so we can expect F-layer DX to be mainly N-S with fewer E-W openings on 15, 12 and 10m. Of course Es livens the summer months and some quite exceptional DX is possible on rare days. This is one of the pleasures of summertime DXing, you can never be sure, even on 6m or even 4m. The latter is band I’ve rarely used.
Back on 10m again for an evening look
CX2ABP(11127km) in Montevideo (GF15wc) has just been spotted here at -25dB S/N on 10m WSPR even though propagation is supposed to be “poor” and he is using 5w.
10m really is my favorite band of all. Propagation supposed to be “poor” yet here is a South Anerican 11127km away on QRP! Now he is -21dB S/N and getting better!
UPDATE 2015z: Weak highly Doppler shifted signals near the bottom of the WSPR band suggest there is some 10m GDX about too. With luck, this may decode before too long? It needs a period with low Doppler.
UPDATE 2050z: CX2ABP has now been spotted 4 times in the last 38 minutes and he is now -18dB S/N which is 7dB stronger than at first. Again, it may be just co-incidence but his best signal corresponds with when Doppler on his signal is lowest. It is as if ALL stations with any drift or Doppler are best when Doppler (or is it drift?) is lowest.
UPDATE 2111z:: Nothing seen since 2038z, so I suspect the band has died out for the day (or the software has ceased working again!). Maybe I should go back on 6m looking for GDX again? I’ll leave it on 10m for another 20 minutes just in case.
UPDATE 2132z: Gone back to 6m GDX hunting. All quiet here so far this evening.
A morning on 10m
For a change, this morning I went on 10m rather than 6m. I had to disconnect the antennas early on because of a passing thunderstorm, but these are the results up to now with 2W out. Basically a fair scatter of 10m Es WSPR spots given and received from across Europe. No DX from outside Europe seen (yet). Hopefully will see some South Americans later.
Sunspot count today is 132 (quite respectable) and 20-30MHz propagation is “normal”.
10m unique WSPR spots (2W) this morning |
Southern Europeans are exchanging WSPR spots with S.Africa (TEP?) at around 8400-8500km, but N.Europeans are missing out.
Tempted to 10m tomorrow?
Knowing my luck, if I QSY to 10m tomorrow then 6m will be in excellent shape, possibly with some long distance multi-hop Es! Despite this, I may start on 10m on Saturday morning and see what happens. I could QSY back to 6m later I guess. Today on 6m has been mixed: some reasonable Es and quite a few locals and semi-locals spotted and spotting me.
Sunspots,10m and 6m
Sunspot count is 102 today (higher than of late) and 20-30MHz propagation is forecast to be “good”, so better than of late. 10m could be better for F-layer propagation today.
So far, it has been quiet on 6m again with just locals spotting me on WSPR – G4IKZ (18km) and G4KPX (14km). No sign of Es yet at 1040z.
There’s a new radio hobby magazine in town!
Recently, a number of hobby radio magazines have either retired, or have merged into a digital mix of several. Filling that void is the new The Spectrum Monitor, a creation of Ken Reitz KS4ZR, managing editor for Monitoring Times since 2012, features editor since 2009, columnist and feature writer for the MT magazine since 1988.
