HAARP to be saved?
The (controversial) HAARP project in Alaska is closing and the facility being dismantled, but scientists are trying to save it. See http://www.adn.com/2014/06/03/3500302/scientists-make-last-ditch-effort.html?sp=/99/100/&ihp=1 . There have been all sorts of conspiracy theories. One of the objectives was to generate uW or mW level ELF signals (to communicate with submerged nuclear submarines) by heating the ionosphere with AM modulated HF signals.

“What a shame if they have to tear it down, they just finished the build out to the full array a couple of years ago!
Anytone and Wouxun Chinese radios
Steadily, the Chinese are entering the amateur radio market. In addition to the “back shed” HF radios, there are now several neat looking VHF/UHF dual band radios and a quad band mobile (Anytone AT5888UV) for 10, 6, 2m and 70cm. See http://www.eham.net/reviews/detail/11197 for reviews of the quad bander.
See also the Wouxun KG-UV8D 5W dual band handheld with a large screen available from UK dealers for under £100. This is even cheaper on eBay.
Anytone also offer a couple of 28MHz radios at bargain basement prices. They are around £199 or less.
The Chinese are coming. Watch out Icom, Kenwood and Yaesu! Your easy ride is nearly over.
I give the Chinese less than a year to come up with a good FT817 replacement at a decent price. Yaesu seem totally uninterested, so I bet the Chinese will be. The market for a good FT817 replacement is certainly measured in hundreds of thousands of transceiver units. Enough to wake anyone up, apart, it seems, from Yaesu.
IF Yaesu is working on a replacement for the FT817 it had better be quick about it as the “window of opportunity” is rapidly closing. Band conditions are slipping, the KX3 is selling widely (but expensive over here in the UK as is the Argonaut VI) and the Chinese are coming up fast on the outside.
Doppler on locals and a VERY quiet day on 6m
Today, so far, it has been exclusively local G4IKZ (18km) on 6m WSPR One thing I have noticed both on his spots and those by G4FFC (45km) yesterday is that when there is a lot of Doppler my reports are poorer. I assume the aircraft reflections sometimes result in destructive interference and an effective drop in S/N.
This month, so far, sunspot numbers have been lower (70 today), although 20-30MHz propagation is described as “normal”. I think the slide downwards is starting, sadly. But, even next autumn 10m should still be good though – we are a LONG way from the minimum yet. I think long distance 6m F-layer propagation openings will be few unless one is lucky enough to be closer to the equator and may catch TEP openings. CN8LI and stations in Israel were managing to catch 6m TEP openings quite recently, as were some VK and JA stations.
UPDATE 1700z: Just G4IKZ (18km) spotting me since I switched on 6m WSPR at 0556z – a very very quiet day on 6m so far today: no Es and no GDX seen here, so far. There is at least one “wandering” signal that has been seen several times drifting across the band but with too much drift to decode. Strong, but no Doppler. At one point it was stable enough to decode but the signal faded out after 1 minute. I think this was an Es signal. May never know though. I am tempted to QSY to 472kHz WSPR this evening unless things markedly improve on 6m.
UPDATE 1808z: another new local(ish) station has just appeared on 6m spotting me: M0MVB (30km) up in the Fens. Still no 6m Es here.I presume M0MVB is just in from work and just turned the gear on.
UPDATE 1925z: Still no 6m Es here today. Tomorrow can only be better.
UPDATE 2050z: I stuck with 6m, but only locals today. Very disappointing indeed.
Quiet 6m evening
Apart from G4IKZ (18km) and G4FFC (45km) all has been quiet on 6m WSPR since the 14 spots exchanged with CN8LI (2113km) – last spot 1558z.
On 2m late afternoon stations were calling “CQ sporadic” on SSB, although when I listened no DX was heard from Europe. I think the Es MUF must have exceeded 144MHz briefly.
Quiet 6m morning
Apart from G3RCE (GDX tropo) there has been no EU DX here on the band all morning. There is some doubt that OZ7IT, in the early hours, was Es, but if it was Es it was indeed very early at 0438z. I shall stick with 6m for a while to see what happens.
UPDATE 1328z: Right out of the blue CN8LI (2113km 5W) was spotted at a strong -11dB S/N . Magic Band does it again!
UPDATE 1420: Now CN8LI spots my 1W ERP at a massive +5dB S/N! During the afternoon we exchange spots 14 times at colossal strengths even though I run 1W ERP only.
2m UKAC results
Last night I went on 2m SSB with 5W in the monthly UKAC activity contest. After 1 hour and 40 minutes I had to stop as my voice was gone (stroke). Best DX missed was GI6ATZ in N.Ireland. I called him a few times without success.
In all 16 QSOs were completed showing that modest power and antenna from the home QTH is enough to enjoy the contest. Had I stayed on longer I’m sure I would have worked more squares. Quite a few stations in northern England worked too on the small, hand rotated, 3el beam, from the home QTH.
Looking at the map, I should have turned the beam towards the SW. Hardly likely I’ll come other than close to the bottom, but that was not the point – it was good fun taking part.
