10m WSPR GDX

Today, during the day, a couple of GDX stations have been copied around 170km range, but these are no longer being seen. To me, this suggests I am copying these stations on back-scatter as once good F-layer goes, so does the GDX. Of course, it could be that these stations are no longer on 10m as the DX seems to have now gone.

UPDATE 2212z:    Only real locals spotting me or spotted by me. No GDX seen this evening, supporting to F-layer back-scatter as the most probable means of the GDX spots earlier in the day. I'll leave 10m WSPR running overnight to see if any GDX is copied. This, of course, requires others to be active too and currently there are very few active UK stations.

UPDATE 2252z:  Just re-synced the PC clock to internet time, so the WSPR should be spot on overnight. However, I am not really expecting to see other than locals until breakfast time, but any DX or GDX in the night would be very good. TX is on about 20% and RX (looking for others) about 80%.  Running 500mW, on the FT817 currently, so I can both TX and RX.

Last stateside 10m WSPR spot of my 500mW

WA4WW (6969km) was the last stateside station to spot me today at 1622z, quite early, at -22dB S/N. The last USA station spotted on 10m WSPR here was WB1FIG around 20 minutes later. He was also -22dB S/N. As I mentioned before, more power really does not seem to matter much. What is more important is that the path is open e.g to the USA. What I'm saying is running 5W, 50W or even 100W would make little difference if the path is closed and the MUF was not high enough. Maybe a few minutes?

First 10m stateside reception of my 500mW WSPR

My first report on 10m WSPR today was at 1150z by KE6BID (5295km) who spotted me at -21dB S/N. This station is located west of Boston, -23dB S/N.  New England, USA.   This is early, boding well for the day on 10m.

Apart from the USA, most stations spotting me are in Russia and nearer Asia. G8KNN (local) is also spotting me.

UPDATE 1241z:   Several other stations (the usual suspects!) spotting my 10m 500mW WSPR now in the eastern USA.

UPDATE 1245z:   M0ITF (170km) is being spotted here on 10m WSPR. Good to see some GDX. I did not check the waterfall in time to see if this was pure tropo or maybe aircraft reflections or F-layer backscatter. Nonetheless -19dB S/N was a decent report for 5W on 10m at this distance. In years go by I'd regularly work this sort of range on 10W with 10m SSB, so pure tropo is quite possible.

UPDATE 1450z:   Spotted CX2ABP (11127km) at 1442z on 10m WSPR at -23dB S/N. He was running 5W, so I am probably still too weak to copy at his end in South America.

UPDATE 1630z:   CX2ABP (Montevideo, Uruguay) has now been spotted here 9 times today already at up to -19dB S/N.  He has not copied my 500mW yet.

Sunspot number and 10m conditions - Sunday Nov 30th

Sunspot number today is 156 and 10m daytime conditions are expected to be "good" again.  As yet, my 10m 500mW WSPR has not been spotted at very great distance although the 10m band opened to the USA earlier than yesterday.

GQRP Club and SPRAT

I have many times said that if all radio magazines had to go, then GQRP Club's SPRAT would be the very last to go. This quarterly magazine is low in cost, very high in simple projects to build and the back page always has GQRP Club sales items.

Of ALL the magazines I see, SPRAT is without doubt the best. Back numbers of this excellent magazine are available on a DVD.

This is a little (sized) magazine but it is excellent value. The best in fact.

Last stateside 10m WSPR spots today

W3CSW (5886km) was the last USA station to spot my 10m 500mW WSPR this evening at 1802z. The last 10m WSPR USA station I copied was also W3CSW at 1808z. He was using 10dB more than I was! It seems that 500mW is quite enough usually if the band is open.

G0LRD (25km) - his 50mW is being consistently copied here.
G4IKZ (18km) - is copying me consistently all evening.

10m WSPR - stateside today

W3CSW (5886km) was the first stateside 10m WSPR station spotted here today at 1230z. My 500mW was first spotted in the USA also by W3CSW at 1246z. Yet again, the USA and Canada are coming through pretty well on 10m WSPR.

Special prefix for Cornwall?

I need some clarification. OFCOM are suggesting the use of GK and similar prefixes for Cornwall a county in south west England. The K stands for Kernow the ancient name for Cornwall. Is this actually happening?

Sunspots

Sunspot number is 166 and 10m propagation is again forecast to be "good".

UPDATE 1632z:   Although, yet again. the 10m band was open to the USA and Canada, my 500mW has not (yet) been copied in South America or further afield today.

10m overnight

Overnight on 10m WSPR just local spots with DX spots only starting after 0730z with spots of Russian stations over 5100km from NO square. More recently, LZ1OI is now spotting my 500mW.
