6m TEP in the Far East and 10m propagation today

Looking at the 6m spots on WSPRnet.com I note the many trans-equatorial spots of VK4TVL by JF1PSS (6176km) with some being of incredible strength (+11dB S/N ) and no drift at all. The VK is running 20W, but even 2W would be enough. Local time looks like early evening.

Over here, I can see no South African or other African WSPR stations active making 6m TEP attempts here a waste of time.

Later unique 10m WSPR spots of my 2W until 1744z.

No great DX here this morning on 10m with EA8/DL9XJ best DX at 2981km  (single hop F layer). There are also a couple of GDX stations at 162 and 184km.

The first transatlantic spot was at 1108z when W4HFZ was copyable at 6819km. He was using 5W. There are other 4 area stations being copied too. The pattern this afternoon is similar to previous days on 10m.

My best DX today is FR1GZ (9724km) at 1550z. Just now I was spotted by VE6ODQ (6640km) in DO34ir (Athabasca).

XP3A - Nook, Greenland on 10m WSPR

For some reason (Win 8.1?) I have had issues today uploading my WSPR spots (that is of others) to the database. I have restarted the software and reset the clock and now all seems to be OK.  Among the first uploads was a strong signal from XP3A in Nook, Greenland at 1932z.. Although strong (+4dB S/N) there was -4Hz Doppler on the signal, perhaps because the signal was coming through the Auroral Oval?

XP3A's QSL card

This was the first time I have seen/heard Greenland on 10m WSPR but I was lucky enough to work Greenland on 15m SSB handheld with my FT817 in my back garden some years ago on just a base loaded whip with  a counterpoise!   I think the mode then was double hop Es. It was an easy QSO. Being able to move the antenna for best signal helps.

Interestingly, a VE4 was suffering -4Hz Doppler just now (signal again passing through auroral oval?). I often see large Doppler shifts on signals crossing the Equator (e.g. on FR1GZ) and I assumes this is due to moving F layers (spread F) as signals cross the magnetic Equator. I would expect TEP signals to have considerable Doppler too.

Phlatlights

When I have repeated my over-the-horizon NLOS optical (red LED) tests at 481THz using LEDs bought from Hong Kong, I must remember to try my Phlatlights which are about 10dB stronger.  I bought these nearly 2 years ago and have not yet fired these up! The ones I have already have heatsinks so it should be quite easy to use these for QRSS3 tests. In theory it should mean aiming a little less critical or greater range when "on-beam".

At 8.7km over the horizon with a clear sky, QRSS3 signals were about 10dB S/N with the 10mm HK LEDs, so with Phlatights and the same optics (100mm lenses) signals should be much stronger. More tests for when I am fitter.

10m today - still good

All afternoon I have been receiving WSPR spots for my 2W WSPR transmissions.  Up to now ALL spots have been from transatlantic stations in the USA. The band is still in good shape.   The sunspot count is drifting gradually downwards (94 today) but, for now at least, HF conditions on the higher bands like 10m remain generally good.

This weekend I may make a start on my Ultimate 3 WSPR beacon kit (see image above on Hans Summers' site).  This is a complete (no PC needed) beacon kit for modes like WSPR and QRSS3 and very reasonably priced even if buying the GPS timing kit too. Mine cost £37 including postage from Japan with GPS.

I feel a bit better than I did and less clumsy. We'll see.

10m yesterday - a remarkable day

10m yesterday was quite remarkable here.

Nothing at all was seen until mid-afternoon and then the band just opened wide!  K9AN (6505km) last spotted my 2W signal at 2308z, which is after midnight local time and HOURS after the band has normally died out. It had been dark for hours. One wonders if this was F2 or even multi-hop Es? I wonder what was happening on 6m transatlantic?  I must check.

Even this morning conditions are encouraging with US7ISA (2634km) spotting my 2W as early as 0750z - very early and much earlier than stations were coming through yesterday. This is eastern Ukraine. Probably F layer but could, I guess, be early Es propagation.

5MHz band - RSGB notice

See http://rsgb.org/main/blog/uncategorized/2014/04/08/important-update-5-mhz-band/ .

The primary user is carrying out some exercises in the next few days and amateurs (secondary users) are asked to use the channels we have carefully to avoid interference to the primary users.

So far, I have only used the band for WSPR on a couple of occasions. It was fun.

Successful 481THz garden tests

Today I repeated my optical tests across the garden receiving signals on my RX with both 600 ohm phones and Spectran software with QRSS3. This time the tests were very successful with signals at least 40dB over noise when scattered off distant bushes (0.34Hz BW).   I think we are nearly ready for the NLOS tests again!

10m late starting today

10m WSPR this afternoon

10m was very slow to get going today and it was not until 1404z that OZ7IT was spotted on WSPR.  Then, there was some some choice DX such as TJ3TS (5478km) and PY2RN  (9550km), the latter who spotted my 2W first at 1446z and several times later in the afternoon.  A few hours later K9AN (6505km) was coming through. Most DX is N-S and transatlantic almost absent. There were some more US stations on later.  ZS6PCO (9100km) was spotted at 1712z. After 1834z most spots are of my 2W from stations in the USA.  It is almost as if someone turned the switch on late today!

Some of the early evening 10m WSPR spots by stateside stations

UPDATE 2130z:  10m is still wide open to the USA. This is quite remarkable after the appalling conditions in the morning.

Later in the cycle, when there are far fewer sunspots, the band will come to life only very briefly and sporadically. In many ways these will be MORE interesting times. This is as long as WSPR operators hold faith with the band even when days go by with not a signal to be heard. I have regularly heard S.Americans on SSB in the solar minimum years. WSPR should be a lot easier.

481THz QRSS3 beaconing across the garden

Last night I fired up my 481THz optical kit with poor results: I think the RX unit may have a flat PP3 battery? On the Spectran display the QRSS3 signal bounced off trees and bushes should be very easy to spot, but for an unknown reason, I was struggling.  I shall recheck all the kit today. The kit has to be well focused and working well to work DX non line of sight (NLOS), which is my plan soon.

My stroke symptoms (poor balance and clumsiness) are really not helping: tasks that were very easy last year are very hard this, well at present they are.  Before my wife and I venture out into the dark fens, I want there to be a good chance of success, which means good and thorough preparation.

All quiet on 10m so far today

Overnight I left my 10m WSPR kit running to see what happened overnight, The last logged station was EA8/LA3JJ at 2018z last evening, so no overnight openings and no GDX around. Perhaps people turn off 10m at night. I usually do and QSY to a lower frequency like 472kHz.

It is now 1247z with a sunspot count of 106 and the 10m band is still quiet with me: no WSPR spots of my 2W signal and no spots of other people yet either. If conditions were good I would have expected some activity from the East already. In southern Europe conditions look better.

See later post for what happened in the afternoon when the band came alive.
