Reduced 10m power from 2W to 1W on WSPR

The Ultimate 3 WSPR beacon kit (on order) gives about 130mW out from a 5V PA supply on 10m. Using a 12V PA and more FETs in parallel should lift this to >1W out, so today I have been using 1W out to see what spots I get. Actually, so far, results are much the same as with 2W.

UPDATE 1244z:  10m band just opened to the USA. Absolutely no problems getting stateside spots at 1W rather than 2W.  Tomorrow I shall use 500mW. Stateside spots ended for me at 1716z.

10m - wide open again

Yet again my favorite band is wide open to Israel, S.America and to North America. Conditions on the band have been excellent for weeks.

UPDATE 1730z:  Band still open transatlantic, 1 hour after dark here, but sounds dead at 1800z.

Bandplan annoyances

Do people who write band plans never actually operate? This morning I saw the latest RSGB band plans in Feb 2014 RadCom and almost tore up the magazine.

For example, and yet again, 10m AM which to my certain knowledge has occupied 29.0-29.1MHz  for YEARS and YEARS and YEARS is not even mentioned and 144.55MHz,which has been the 2m AM centre of activity for many years is mentioned begrudgingly just in a footnote as if AM  was disgusting! Yet we have a FAX calling frequency! Why is the RSGB so blatantly anti-AM?

Frankly I am appalled. Idiots.

10m transatlantic - yet again

10m is again wide open across the Atlantic again this afternoon. In fact, since coming out of  hospital on Jan 3rd it has been wide open more or less every afternoon that I have checked. Sunspot count remains good.

1710z:  10m band was still wide open across the Atlantic, then someone turned the lights off here!

Australian QRP reports on 3 bands

Today VK6XT copied my 2W WSPR signal on 10m at 14719km. This now means my QRP WSPR has been copied in Australia on 10, 20 and 40 m these last few weeks. HF conditions are clearly in good shape of late.

VK on 10m this morning

10m is again in great shape with a couple of VK spots in with the other stations this morning. The following are the unique stations spotted on 10m WSPR. In most cases,stations were actually spotted multiple times.

10m still good transatlantic

Although I did not get on the band until mid afternoon.the band is again wide open with plenty of USA and Canadian stations coming through plus a CX station from S.America.  Sunspot count is still well over 100 which helps.

Update 1815z: 10m is still wide open almost 2 hours after sundown here is Cambridgeshire.  Conditions are good. Now at 18.35z the spots have stopped so I suspect that is it  for this evening.

More on the Ultimate 3 kit

Hans Summers G0UPL has answered my questions so I am going to buy a kit for 10m WSPR use. As it stands the 10m output is 131mW from a 5V PA supply, but this can  easily be increased. I think 2W is a more useful level. At well under 40 UK pounds including GPS this is good value.

Update 1600z:  the 10m WSPR beacon was ordered today but not the GPS unit which is out of stock. This kit will be a test of my current abilities (building wise) following the stroke.

Ultimate 3 WSPR beacon with GPS timing


Image is at http://www.hanssummers.com/images/stories/ultimate3/1/2.jpg
Hans Summers has a new beacon  kit that allows full "stand alone" (no PC needed) WSPR beaconing. It is available for just  £17.50 with a low pass filter for any particular band plus £14 for the high sensitivity GPS module and patch antenna. I believe power out is around 150mW but this can be increased. As I understand it, it means, for example, a 10m WSPR TX beacon that does NOT need a PC can be made for under £40 even building a separate PA and putting it into a nice box. The unit also does other modes like QRSS and HELL.

See G0UPL's website at http://www.hanssummers.com/ultimate3.html .

I shall have to build one to free up the FT817.

10m GDX and DX

After last evening when even 20m was dead as a dodo,10m WSPR was lively this morning both for GDX and DX. I suspect the GDX (184 and 121km) may have been back scatter although the Doppler (3Hz) suggests possible aircraft scatter. All the more surprising not to get G3WKW the other evening (134km). The DX exchange was with a DL station in the Canary Is (West Africa). This could be F layer or  winter Es.  Sunspot count 134. Later 4X1RF spotted me at just over 3500km. The first USA station (an N2) was seen at 1322z today (7088km). 10m looks in good shape today. It was still open (for me here) to the USA/Canada at 1728z. At the moment (1900) the WSPRnet database is down, so I cannot check if 10m is open to the USA for others.

10m WSPR until around 1300z today.
