Multi-band WSPRing?
Now I have my fully stand-alone 10m WSPR-AXE unit, I should be able to WSPR on MF (with the earth-electrode antenna) or on 6m at the same time. I have yet to try this out but this means I can WSPR on 2 bands at once should I want. 6m might be fun although I've had no success to date lately on 6m.

10m WSPR-AXE reports
So far this morning (it is now 1045z) I have received 50 separate reports using my 10m WSPR-AXE 500mW beacon (sent to me by W5OLF). The little, fully self-contained, beacon (no PC needed) works very well indeed. After about 20 minutes settling time, the drift is essentially zero. Some of the reports below show the beacon still settling. I thoroughly recommend this unit. It is such FUN to use and see all the reports coming in. Just a single small PCB and it fits in a small enclosure. With my poor voice, it is an excellent way of enjoying the hobby and checking propagation - all at very low cost too. What I like is that it is all on a single PCB. Although the Ultimate 3 kit from Hans Summers covers more modes and is less expensive, it is on several PCBs and is slightly more complex. The W5OLF WSPR-AXE beacon matches my needs perfectly.
UPDATE 1148z: Spots this morning being received from right across Europe from Finland (OH) in the north to Italy (I) in the south and Ukraine (UR) and Bulgaria (LZ) in the east, plus Israel (4X), all with the tiny WSPR-AXE 500mW unit. Further afield later?
UPDATE 2000z: Apart from the very many spots from the USA, no other DX was spotting me. I was hoping for a spot from Australia, but that will have to be on another day. Judging by my reports so far, I think this is just a matter of time.

QRP radios
I continue to be surprised by how few affordable QRP radios are on the market. The FT817ND continues to be the favourite, but recent exchange rate changes have not been matched by decent falls in the UK retail prices. I think we are still being ripped off by dealers in the UK. The IC703 is no longer made and the KX3 from Elecraft is very expensive over here. There are a few lower cost Chinese HF radios appearing. Overall, there remains little choice in QRP transceivers at sensible prices. I am sure the KX3 is a very good radio but for the same price I can buy 2 FT817 transceivers, and these are all mode and to 70cms.
A multi-band, all mode, 5-10W radio would be a killer in this age where people take lots of holidays and are on the move frequently. I still fail to understand why the big Japanese manufacturerers have not got a raft of low cost units on the market. It seems a gold mine opportunity is being wasted. Maybe I have misread the market?
I know if there was a new, attractively featured, QRP transceiver on the market now at a sensible price I'd be in the line to buy. I am sure very many others would be too.

10m stateside
Conditions on 10m today definitely seem poorer than yesterday. I am still using my little 500mW WSPR beacon by W5OLF. There were spots all day from UR/SWL56 and this afternoon from 4X1RF (3519km), all afternoon. So far, 4X1RF has spotted me 20 times.
My first USA spot was WG2Z (5600km) at 1220z. Since then I have had USA spots from several USA stations, but I think fewer than yesterday. The W5OLF WSPR-AXE 10m 500mW beacon really does work, without a PC. I am still in awe that something so small and beautiful is copyable so far away. It would fit in an Altiods tin - a real favourite with QRPers.
The beacon is still on and running, but I don't expect any magically far DX between now and switch off, which will probably be around 1830z.
UPDATE 1902z: I am just about to turn off my little W5OLF 10m WSPR beacon. The last stateside station to spot my 500mW was KB9AMG (6300km) at 1712z - no other spots since. Definitely conditions on 10m were not as good as yesterday. Still, yet again the 10m band was open to the USA and 500mW was quite enough. Worse report was -25dB S/N with most reports in the teens suggesting even less power would have been enough.
UPDATE 1910z: 10m WSPR beacon is now off.

Using my W5OLF beacon again on 10m WSPR (500mW)
Since about 5 minutes ago, I am again WSPR beaconing using 500mW from the tiny W5OLF 10m WSPR beacon. It is still settling, but already being spotted well in southern Ukraine by UR/SWL56 (2283km) at -14dB S/N.
UPDATE 1055z: At the moment only UR/SWL56 has spotted me. It looks like conditions are NOT as good as yesterday?

How do they ever make a profit?
On the internet you can buy a dual-band handheld with antenna, battery, chargers(2), earpiece and belt clip for just £25.29. At this price I find it unbelievable they can make a profit. I think it is even cheaper if you buy a batch of 3.

70cm UKAC this evening (5W QRP)
70cms 5W QSOs this evening from home - best DX 105km |
I worked 8 stations in 3 grid squares before I HAD to stop. I heard a station in IO81 but failed to work him as my beam (5el hand rotated) was way off. Best DX was just 105km. Had I managed to stay in the contest longer, then I am sure more QSOs would be in the log. My normal 70cms range seems to be up to about 200km.
Conditions seemed poor and activity was lower than in the summer. I guess better weather brings out more portable stations. Most stations worked were fixed i.e at home or on club premises. At this time of the year people prefer to stay home. I cannot blame them!
Last USA spot this evening
WG2Z (5600km) seems to have been the last station in North America to spot my 500mW W5OLF WSPR beacon at 1716z. Since then, just local G4IKZ (18km) has been spotting me. I am very impressed with Jay's little beacon - it works very well.
UPDATE 1900z: Went QRT on 10m WSPR at about 1900z as all DX seems to have stopped now.
