Sunspots and 10m - Fri Jan 15th 2016

Solar flux is 104 and sunspot number 36 (K=3) today. 10m propagation is expected to remain "poor".

Australia on 20m WSPR

As we had visitors, I decided to use the WSJT-X V1.6 on 20m WSPR this afternoon. As well as lots of USA spots, I was spotted in Australia twice. Obviously the low Par antenna does a very credible job on 20m. Best DX was VK3AXF (16850km).

Sunspots and 10m - Thurs Jan 14th 2016

Solar flux is 103 and sunspot number 26 (K=3) today. 10m propagation is again expected to remain "poor". 10m is not likely to be great today, at least not on F2,  although wintertime Es may liven things up again.

Yet more wintertime Es on 10m WSPR

All afternoon, 10m WSPR has shown plenty of evidence of wintertime Es with lots of spots from middle Europe.  December and January are the peak months in winter for Es although May, June and July are the best for Es.

Sunspots and 10m - Wed Jan 13th 2016

Solar flux is 106 today and sunspot number 29 (K=2). The forecast for 10m propagation remains "poor". More in hope than expectation, I have been on 10m and 6m WSPR since breakfast. Overnight I was on 630m WSPR but just the usual stations, again.

We are definitely on the slide down the solar cycle, but 10m becomes more interesting, not less, as the sun goes "off the boil". Es enlivens 10m for several months each year and the band still supports QRP SSB DX N-S even in the worst years. 10m is a great band if you like a challenge and WSPR in the declining years on 10m should help to winkle out those fleeting openings. Never give up on this great band, our biggest HF band by far with space for most modes.

UPDATE 1010z:   No spots as yet on 10m or 6m WSPR although it is still very early.

Sunspots and 10m - Tues Jan 12th 2016

Solar flux is 109 today. Sunspot number is 41 (K=3). 10m propagation is expected to remain "poor" although, like yesterday, some wintertime Es may liven things up a bit.

10m and 6m WSPR

Overnight I was on 630m WSPR where I gave and received spots to/from the same few stations. At the moment I am in 10m and 6m WSPR but I hope to go on JT9-1 (probably on 20m) later in the day.

10m and 630m WSPR

My 10m WSPR beacon is still running and I am also active on 630m (5mW ERP 20% TX, 80% RX no preamp and earth-electrode "antenna").  At 2000z I shall QSY to 144.575MHz FM for the East Cambridgeshire net. As my voice is not good, I try not to speak too much and usually finish by 2030z. I shall go back to 630m WSPR after I finish on the net.

UPDATE 2255z:  I see that David G0LRD (25km), who very kindly came over and erected my 2m Big-Wheel antenna,was spotting me on 630m.  I shall remain on 630m (472kHz) WSPR overnight although I went QRT on 10m WSPR some hours ago.

G0VQH and 472kHz RX

Jenny tells me she uses orthogonal loops and an active antenna on 472kHz located at the far end of her garden, which must be quiet electrically.  It certainly works very well as she decodes far more than I do on 472kHz RX. If my health permits, I must try an active RX antenna on the band.

10m Es

There was wintertime Es about today on 10m WSPR with spots (lots) of my 500mW WSPR beacon from Germany and Hungary. At the time of writing, 1540z, there have been no DX spots and nothing at all on 6m.

UPDATE 1556z:  I think there are definitely fewer stations on 10m WSPR and 6m WSPR, so the value of going on this mode diminishes. It needs a decent number updating to WSPRnet to get the real value from the mode. It is a pity there are not more people on WSPR. JT65 and JT9-1 really are 2-way modes and need me to be actually in the shack.  SSB is hard work for me at present and even CW requires my brain to work overtime! As I said before, I propose to use 2-way digital modes far more this year.

UPDATE 1756z:  HA4ULB (1456km) is still spotting me on 10m. I have also been spotted in Italy: classic wintertime Es.

Sunspots and 10m - Mon Jan 11th 2016

Solar flux is 108 and sunspot number 73 (K=3). 10m propagation is again expected to be "poor". Currently I am active on 10m and 6m WSPR.

472kHz compromise antennas

Looking at nearby G0VQH's list of WSPR stations successfully decoded on 472kHz WSPR it is clear Jenny is copying far more stations than me. Even with my preamp in circuit and maximum sensitivity I am simply not copying, at all, some stations. I think it is time I tried an E-field probe on this band on RX. It is a combination of antenna (in)efficiency and directivity I think that is stopping me copying more on MF now.  I'm not sure what Jenny is using on MF but it clearly works well.

Sunspots and 10m - Sun Jan 10th 2016

Solar flux is 106, sunspot number 84 (K=1) and the forecast for 10m remains "poor" today.  I am not expecting great things of 10m today.

Back on MF

As I don't have to be in the shack for WSPR (I can monitor in the lounge, or even in bed!) I have returned to 472kHz (630m) WSPR.  It takes a few seconds to pop in the shack if anything is amiss.  I am able to use a different PC in the lounge and my iPod Touch in bed.

UPDATE 1846z:  Nice no see I was spotted by a new reporter this evening M0TAZ (79km). DK7FC (669km) has been spotted as usual.

Sunspots and 10m - Sat Jan 9th 2016

Solar flux today is 109 and sunspot number 80 (K=2). 10m propagation is again expected to be "poor".

10m WSPR earlier today

EA8/DK5HH (2951km) spotted my 500mW 10m WSPR beacon at 1202z today. I think this was single hop F2 propagation. Although not super-DX, it does show that there is still life on 10m. WSPR is ideal for "smoking out" short transient 10m openings.

Sunspots and 10m - Fri Jan 8th 2016

Solar flux is 95 today and sunspot number 29 (K=2). 10m propagation is expected to be "poor" so I am not hopeful of decent results on 10m today.  We are definitely seeing the effects of falling solar activity sadly, although at times 10m is good so never give up on the band. This is exactly where WSPR is useful. At present I am active on 10m WSPR and 630m WSPR.

472kHz WSPR

I am back on 472kHz (630m) WSPR (5mW ERP 20%, RX 80%) and will remain on overnight.

UPDATE 1004z 8.1.16:  No surprises overnight.

20m WSPR and JT9-1

As I was busy with other things all morning I was active on 20m WSPR. We are out most of the afternoon so JT9-1 may have to wait until I have more time in the shack.

Sunspots and 10m - Thurs Jan 7th 2016

Solar flux is 101 today and the sunspot number 38 (K=3). 10m is expected to remain "poor" again today.

Presently I am on 20m WSPR using the new shack PC running WSJT-X V1.6 and the Par end fed 3 bander, which is low on 20m. Already VKs have spotted me.
