ZL2IT (18569km) running 5W was spotted here on 10m WSPR this morning at 0946z, not long after turning the rig on. He was not strong at -25dB S/N. As yet, no reports of my 500mW from Australia or New Zealand today.
Just Europeans spotting me so far this morning. Distances seem to suggest F-layer propagation, although I am unsure about some of the closer stations e.g. Italy which could be back-scatter or even Es. Every day now my 500mW is copied right across Europe.
UPDATE 1105z: Just spotted LX and DL on 10m WSPR. This far too short for F2 propagation. I suspect this is Es as there are now lots of closer EU stations being copied. No Doppler evident on these signals.
UPDATE 2200z: The day ended with reports of my 500mW WSPR from no further than the USA. In 2 years time I'd be thrilled to bits with this! Today, the USA and Canada are easy even with 500mW.

Last transatlantic spot of my 500mW on 10m WSPR?
| WG2Z (5600km) was spotting me well at 1842z but no-one else from the other side of the Atlantic has since then. Only time will tell if this was the last one tonight. I shall stay on 10m WSPR for a few more hours yet. G0LRD (25km) running 50mW s now the only station being copied currently. UPDATE 2004z: WG2Z at 1842z does appear to be the last USA station spotting me today. The last USA station that I copied was also WG2Z in the immediately preceding time slot. The 10dB difference in power seems to make no difference: once the path closes, that is the end of it. UPDATE 2042z: Still just G0LRD (25km) running 50mW being copied now on 10m WSPR. I shall probably go QRT at around 2100. UPDATE 2155z: Now QRT until after breakfast time tomorrow. |
Our varied hobby
One of the great things about amateur radio is the number of different ways in which the hobby can be enjoyed.
For over a year now my health has been poor because a brain bleed in September 2013. Before then, I enjoyed QRP QSOs (mainly SSB), construction and field experiments from VLF to optical. Since my stroke I have been clumsy and (until recently) not allowed to drive. Very very slowly, normality is returning but I think it will be way into 2015 before I can call myself well.
In the meantime, I still manage WSPR and other digital modes from home. I can even, albeit briefly, manage our local 2m FM net and the occasional VHF/UHF contest. Some people enjoy satellites, MS or moonbounce. Others just like to ragchew on 80m.
We must rejoice that there are so many different, yet equally valid, ways of enjoying ourselves. We have a great hobby.

10m WSPR - too easy right now?
Conditions on 10m really are good right now and in a few years time it will be hard to believe how good they really were. Enjoy the good times - it may be a very long time, if ever in some of our lifetimes, before we see such F2 conditions on 10m again. Yes 10m is ALWAYS fun in the spring and summer months when Es is good but right now F2 propagation on 10m in the daytime is very good and worldwide DX is possible.

VLF amateur radio
Being involved in VLF amateur radio is a very specialised activity requiring special (but low cost) kit to be successful. Casual listening is highly unlikely to be successful. Long distance reception of amateur VLF signals usually involves looking for signals using Spectrum Laboratory software locked to a VLF MSK signal so that very narrow bandwidths can be looked at for hours or days on end.
Most amateur VLF tests are done on 8.27kHz as this is unallocated spectrum in many countries.
News about amateur VLF activity can be found at https://sites.google.com/site/sub9khz/ . There has been very little amateur VLF work done this year but amateur VLF signals have crossed the Atlantic.
Tests using utilities assisted earth-mode do not involve big loading coils. Just under 6km has been achieved with just 5W using this mode, before I had my stroke! The kit was simple too. See https://sites.google.com/site/sub9khz/earthmode .
One of the things I am really looking forward to, when fit again, is some more field work with VLF using earth-mode.

Sunspot number - Dec 4th 2014
Sunspot number today currently is 124 and 10m daytime propagation remains good. 10m is again open across the Atlantic, and my 500mW 10m WSPR is reaching further afield too.

VK5MR
I may have missed being spotted on 10m WSPR this morning by VK5MR (South Australia) as he was spotting G stations well this morning, but well before I came on air at around 1000z. Looks like I need to have everything on and working an hour earlier to be spotted.
UPDATE 2105z: Time to go QRT on 10m.
UPDATE 2215z: Finally went QRT on 10m WSPR at 2210z.

Last stateside spots of my 500mW 10m WSPR tonight
Canadian VE2MLS (5422km) and W3CSW (5886km) spotted me at 1728z. At the moment these look like the last spots from across the Atlantic.
UPDATE 1920z: No further reports from across the Atlantic since VE2MLS and W3CSW at 1728z, so these were almost certainly my last transatlantic reports this evening.

27 unique WSPR spots so far today on 10m with 500mW
So far today (it is 1530z as I write this) 27 different stations have reported my 500mW on 10m WSPR. Most are stateside stations in the USA and Canada. This has been the pattern for weeks and weeks now.
Every day, the 10m band opens across the Atlantic around lunchtime and usually closes to the USA and Canada just after teatime. 10m is a wonderful band to be enjoyed by all at its best. It is still fun at other parts of the cycle too, but FAR more quiet.
UPDATE 1600z: Best DX is now N6RY (8756km) just south of Los Angeles on the west coast of the USA.
UPDATE 1930z: 32 unique 10m WSPR spots received in the last 12 hours with 500mW - not a bad day, but no "super" DX spots today.
