Concentrating on one or two bands?
With limited space for antennas, it seems sensible to concentrate efforts on just a couple of bands only. As my favorite band is 10m, I am tempted to erect a more efficient antenna for this band and maybe put up the 6m V2000 only during the Es season. My problems are (a) a lack of mobility because of my stroke and (b) choice of compact, efficient antennas. At present I can cover 40, 20, 10, 6, 2 and 70cms, plus 630m rather inefficiently with my earth electrode antenna. Perhaps, whilst my health is not too good, I am better sticking with what I’ve got? I know that on 10m my antenna could be better but the Par end-fed covers 3 bands (10, 20 and 40m) and my 2W QRP has reached VK on WSPR on all these bands and doesn’t do a bad job.The Par is is almost impossible to see in the air.
6m GDX tonight
No Es here on 6m WSPR since I QSYed to 6m around 1500z. There has been some GDX again, G8JNJ/A (184km) was spotting me at -24dB S/N at 2128z. Doppler was low suggesting tropo without aircraft reflections, or aircraft crossing the path at right angles (so little/no Doppler).
Again I am bitterly disappointed with the lack if USA/Canadian east coast stations on WSPR. As of 2145z there were still ZERO stations active on WSPR from that area. Come on lads! Give we Europeans a chance of being spotted over there!
Unless there is some interest from the east coast USA/Canada on WSPR very soon it will be time to abandon 6m WSPR this season. I have been spotted all over Europe, in N.Africa and in Israel (3519km) with just 1W ERP in the last few months. I was hoping for the USA or Canada on WSPR this season. If there are zero stations at the other side there is no point in continuing.
New Chinese multi-mode HF rig – Xiegu X108
Steve, G1KQH has sent this link about a new Chinese multi-mode transceiver. See http://www.brickolore.com/ . Prices start at 2800 Yuan apparently. It is called the Xiegu X108. There is a video and some pictures of the rig.
To my mind, this still looks like a “back shed” radio, rather than a mature, well engineered and thoroughly well tested radio. I may be wrong. I am still waiting to see when the Chinese launch a proper Yaesu or Icom competitor. These will come but I’ve not seen one yet. Maybe in the next 12 months?
Ten-Tec Argonaut VI
See http://www.tentec.com/argonaut-vi-qrp-1-10-watt-transceiver/
Despite missing some key bands, all reports are this is a very good QRP radio from Ten-Tec. However at $995 in the USA (similar in £ in the UK with import duty and VAT tax) it is simply too expensive to ever consider.
All I can say is are Ten-Tec in financial trouble? The true market price here in the UK must be less than £700, so they are about £300 adrift in my estimation.
Even in the USA $995 for a rig with no 60m, no 12m and no 6m is way over the top. Just compare with the FT817ND for example. Even the Elecraft KX3 is much better value, in my view.

10m Es – more and more
It is now 2015z and on 10m the Es keeps on coming. This is a good, solid and widespread Es opening.

| Recent 10m WSPR spots this evening |
UPDATE 2110z: 10m Es still going strong a few minutes ago.
UPDATE 2145z: Es seemed to have stopped (here) at about 2100z. Oh no it didn’t! IK1WVQ was spotted at 2134z and 2142z.. HB9JOI spotted me at 2138z. The Es is still going strong.
UPDATE 2220z: Although Es has been good on 10m all day and F2 was good to FR1GZ earlier, there has been no F2 to South America on 10m WSPR at least not yet. This was surprising. EB3EPR is still spotting me at 2218z.
UPDATE 2232z: Bed time, but 10m WSPR still running overnight, unless the PC does an update and closes the software again!
DK6UG, DC3RJ and EA1KV by Es on 10m WSPR
As teatime continues, yet more Es 10m propagation is evident.
DC3RJ (817km) is the latest who spotted me at 1754z. Earlier EB3EPR (1248km) spotted me twice. Now EA1KV (1304km) and DK6UG are spotting me at 1806z.
Some weeks ago I was questioning the propagation to a GM reporter on 6m, but realise now the distance is comparable with parts of Germany, so an easy Es single hop.
UPDATE 1840Z: HB3YHB (793km) was spotted at 1838z on 10m WSPR.
More 10m GDX, Es and F2
During the afternoon G4FFC (45km) and M0BOB (74km) were both copied on 10m WSPR. These are both outside local range and I would class these as GDX (just). Both show some Doppler so may be helped by aircraft reflection.
On F2 FR1GZ (9724km, Reunion Is) was being copied until 1512z, so good F2 propagation. I wonder if we’ll see South Americans later?
Es disappeared (here) at 1404z but may return this teatime.
UPDATE 1740z: EB3EPR (1248km) spotted me at 1736z and 1746z so Es is back (it is teatime!).
