10m - my favourite band of all

There is something very special about the 28MHz (10m) band. It is hard to put my finger on why I enjoy 10m so much - probably it is the great variety of propagation - but it is, for most of the sunspot cycle, more fascinating than any other HF band. April-September 10m seems to support Es and there is a second Es peak at Christmas/January.  F2, especially over N-S paths seems to be present right to the sunspot minima. GDX (inter-G DX) seems to be possible by tropo or aircraft reflection at almost any time to at least 200km. Of course it is useful for local QSOs too. In all, it is a great band to be enjoyed all year around and at any time in the sunspot cycle.  In the quieter years it behaves more like a VHF band but not completely so with F2 still possible. Es seems to enliven the band for quite a bit of the year too. Another bonus is that antennas are small.   Please, never give up on this splendid band.

UPDATE 2100z: There is still 10m Es and 10m F2 propagation.  PT2WWV (8873km) has recently spotted my 2W WSPR (2050z) at a very strong -9dB S/N.

Yaesu launch FT991 in Japan

Ever alert Steve G1KQH has spotted that Yaesu launched the new FT991 at the Tokyo Ham Fair in Japan as a replacement for the FT897D. See http://qrznow.com/yaesu-ft-991/ .

This looks a very neat, small, multi-band, multi-frequency rig, as long as the price is sensible. In Jaoan, they usually sell a QRP version too. It would be good to see a 20-30W version in Europe too. This would compete well with the (now stopped) IC703 rig by ICOM.

The image is linked from the http://qrznow.com/yaesu-ft-991/ site. The image is NOT resident on this site. Please follow the link for details of this rig. I have no further details.

There is no sign of a replacement for the FT817ND rig. I think Yaesu must have abandoned plans, which is a shame.

10m in good shape yet again

Today Es has been good again on 10m. FR1GZ (9724km) was spotted this morning and PT2WWV (8873km) was by spotted by F2 several times already by WSPR.  I have been monitoring 10m most of the day and will continue this evening.

Sunspot count is a decent 124 and 20-30MHz propagation is "normal". I was NOT surprised to see PT2WWV a little while ago by F2.

I have been spotted by several stations around Europe today (Es). Today seems like another excellent day on 10m WSPR.

UPDATE 1945z:  Still plenty of Es about on 10m WSPR.

10m F2 again this evening

Recent 10m WSPR spots
Right on schedule PT2WWV (8873km) was spotted 4 times (already) after tea today on 10m WSPR (1904-1928z).  I think this is pure F2, but there is an outside chance it is Es and F2 combined (first hop Es then F2) as EA5CYA was also putting in an appearance by Es on 10m WSPR. Conditions on 10m have been good N-S of late.

UPDATE 1945z: PT2WWV again spotted. Plenty of 10m Es too.

UPDATE 2020z: PT2WWV has been spotted 9 times already by 2012z.

UPDATE 2115z: PT2WWV has been spotted 14 times so far this evening here and he has spotted my 2W already 3 times. I am afraid that 630m (472kHz) has been abandoned for a few nights whilst 10m is so good. 10m WSPR will be left running during the night.

Sunspots

Sunspot count today is 139 (good) and 20-30MHz propagation is "normal" so there is a fair chance of F2 today on 10m.

10m Es today

The main (N. Hemisphere) months for Es are May, June and July but Es has been good on 10m right through August and I suspect September will still be quite good on 10m. Actually, I suspect 10m Es will be present probably every week throughout the year but at a much lower level.  If stations "stick with" 10m into the quieter months, I suspect far more openings will be detected than in the past. Of course this coming autumn, winter and spring we'll still have F2 to enjoy, probably to all parts of the world on 10m.

10m F2 this afternoon/evening

Not unexpectedly, FR1GZ (9724km) was spotted here by 10m WSPR at 1520z. I was expecting to spot him earlier. OK2SAM (1283km) has been spotted by Es many times this afternoon. LU7YW is on and may spot me later with luck. He seems to be RX only.

UPDATE 1925z:   PT2WWV (8873km) was spotted by F2 3 times after teatime. He has spotted my 2W once.

UPDATE 1940z: As 10m is still open to South America, I have decided to stick with the 10m band and NOT move to 472kHz until later tonight, if at all.

UPDATE 2105z:  PT2WWV (8873km) is still coming through at 2056z. He has spotted me 5 times and I have spotted him 14 times this evening so far. I suspect the band will be open a while longer. There is still a lot of Es around too. Today 10m has been very good.

LNR Precision 5 band HF transceiver - the LD-5

Steve G1KQH has found a link to this new transceiver https://www.facebook.com/pages/LnR-Precision-Inc/229134337165152?hc_location=timeline. It looks a bit like the Elecraft KX3 but I hope it is much less expensive as it only covers 5 bands on TX.
LNR are the people that make the Par line of antennas now. They hope to start taking orders in September. Apparently they had quality issues in China with the 4-band version.

10m, 6m, 630m (472kHz ) WSPR

Overnight, I was on 472kHz but spots (given and received) were from people I'd seen before. No new reports/reporters. After a very brief pause on 6m (just G4IKZ spotting me at 18km) I have now settled on 10m for the day. EA5CYA (1376km) was spotted at 0940z and 0954z by Es. Otherwise quiet so far.

Sunspot count today is 128 (decent) and 20-30MHz propagation is "good".  I think today it is likely we'll see F2 propagation on 10m WSPR today as long as there are WSPR stations active in the right places.
UPDATE 1035z: EA5CYA still there on 10m Es.

UPDATE 1206z : The 10m Es opening is now quite widespread with several different central and eastern European countries in evidence.

UPDATE 1256z:  The 10m Es opening seems to be towards Scandinavia now with spots from SM67464 and LB9YE.

UPDATE 1315z:   OZ7IT and I are exchanging 10m WSPR spots.

Back on 472kHz again

Since about 1930z I have been on 472kHz WSPR using the strapped feeders to my V2000 VHF/UHF vertical and 2m halo. So far just the usual suspects spotted and spotting me i.e. no-one new.

It is likely that in the next week my amateur radio operation will be compromised as we'll have grandchidren here and their parents. For some of the time my shack will be a bedroom. I shall try to run 472kHz WSPR until Tuesday if I can. 10m by day and MF evenings and overnight.
472kHz unique WSPR spots in the last hour.
