10m - closed now?

It is now 1857z and there has been no Es here now for over an hour. In the periods I was monitoring 10m, no F2 propagation was spotted. No GDX seen either in the last few hours.

I will QSY to 472kHz shortly I think.

I was thinking of buying a dedicated 10m rig, but unless my voice rapidly soon improves  (SSB, FM and AM are hard work for me because of my stroke) this is probably a waste of money at the moment. For now I shall stick with 2-5W on digital modes, which I can manage with the FT817 rig. JT65 and JT9-1 are my best bets. PSK31 is quite hard as it requires (near) real-time keyboard skills. I rather dislike PSK31 with macros -  you can usually tell when someone is using macros - I much prefer real QSOs. At least JT65 and JT9-1 use very formulaic formats for minimal data QSOs. QSOs are very very basic, but for me this helps at the moment. One reason I enjoy WSPR is it tells you about conditions on a given band and once set up, it just runs with minimal intervention. Some will (rightly) say it is computers talking to computers. At the moment, this is close to what I need. JT65 and JT9-1 are proper 2-way modes.

New band tried with "compromise" antenna.

This afternoon I tried 80m WSPR with the "compromise" antenna (V2000  + 2m halo with strapped feeders) with some success. On 80m I copied M0BLP and PA0WMR although there were very few stations active. I was not copied by anyone. I was going to try 160m but decided there was too little activity.

Later I used 40m and 20m with the Par end-fed.  On 40m, just one transmission resulted in 10 spots in 7 countries. The next transmission resulted in not a single report, probably because I was sitting on the frequency of a very strong station who was TXing at the time?

I later returned to 10m, and spotted EA5CYA (1376km) and LZ1OI (2145km) by Es around teatime. The Spanish station was pretty strong but the LZ was much weaker.

Sunspots and 10m

Current sunspot count is 89 with 20-30MHz propagation "normal". There may be some 10m F2 around on 10m today.  Just QSYing to 10m WSPR now.

Although there will still be 10m Es propagation, I doubt it will be as good as in May, June and July.

UPDATE 1130z:  Already 10m has been open by Es WSPR to CT1JTQ (1843km) and SI9AM (1503km) as well as GDX to G4HZW (209km). Not a bad start and it is not even lunchtime yet.

472kHz WSPR - overnight again

At the moment I am still on 472kHz WSPR having kept the WSPR running through the night. Same stations in the logs - no new reporters sadly - and again GM4SLV (896km) is still giving me daylight spots. Currently I am using the V2000 VHF/UHF vertical and 2m halo both with strapped feeders as my "compromise" 472kHz antenna. Ground is mains earth plus one shortish radial with single ground stake. I may give this antenna a try on 160m and 80m, just for fun.

These are the results in the last hour on 472kHz:

Recent 472kHz WSPR spots

Later I shall QSY to 10m as daytime 472kHz activity is very low.

Spoiling the natural environment, or not?

The beautiful Kingsbridge Estuary

The petition to NOT allow water skiing in the Kingsbridge Estuary is gathering momentum. The last time I looked there were 851 supporters of the "no" vote. If you want to support the campaign, then go to the link and vote. The more people who support the "no" campaign, the better chances we have of preventing this precious habitat and SSSI being ruined forever.

UPDATE 2015z:  856 votes now.  Keep voting!

Back on 472kHz WSPR

After a brief foray on 6m WSPR, I have returned to 472kHz WSPR now. Antenna current is higher than last night (on the V2000 and halo with strapped feeders) and the only difference is the weather. I assumes the ground is wetter. So far, the usual stations although PA3TKF (286km) was a new station to spot earlier, bringing me up to 20 unique spots this summer. Again, I am sure that I should be able to copy lots more stations and they spot me too.

2m WSPR

As I knew G3ZJO and G0LRD were both active on 2m WSPR this morning, I ventured onto 144.492MHz USB dial on 2m. I was immediately rewarded with a spot of G3ZJO (79km). During the morning G0LRD (25km) has spotted me multiple times and I have spotted Eddie, G3ZJO, three times now. Interestingly, Eddies signal was accompanied by up to 6 aircraft Doppler shifted signals. His signal decoded far fewer times than he was visible.

G3ZJO (79km) non-decoding 2m WSPR signals with lots of aircraft Doppler.

In the UK and Europe 144.492MHz USB dial is the frequency of choice, NOT the frequency recommended.  I believe some in Europe have birdie problems on the recommended frequency.

Different 472kHz antenna

Since about 1838z I have been using the strapped feeders to my triband VHF/UHF vertical and halo as my 472kHz antenna.

472kHz WSPR unique spots (of me) so far this summer

Antenna is higher than the Par triband HF antenna with strapped feeder but the antenna current is about the same. If the effective height is a bit higher (it should be) then ERP should be higher too. Initial results suggest in some directions it is down on the earth-electrode antenna but I do seem to be getting more spots at each transmission than on the earth-electrode or Par antennas. G4VJF(151km) is a totally new reporter tonight bringing the number of spots of my 472kHz WSPR this summer up to 16 now.

UPDATE 2032z:   29 active stations on 472kHz this evening.

UPDATE 2044z:   Now 34 active stations on 472kHz.

UPDATE 2055z:   Currently getting about 4 spots per transmission on 472kHz.

UPDATE 2145z:   Now 38 active stations on 472kHz. Will leave 472kHz WSPR running through the night to see how latest (compromise) antenna performs.

Sunspots today

Sunspot numbers are down a bit at 92 (disturbed) and 20-30MHz forecast is just "fair". I think it is unlikely we'll see F2 propagation on 10m today, but you never know on 10m.

Yet again, there seem to be few stations at F2 ranges active on 10m WSPR today. At the time of writing (1302z) there are 32 stations active worldwide on 10m WSPR. FR1GZ is on and he is at classic F2 range.

472kHz WSPR - more on the earth-electrode antenna

Overnight I continued using the earth-electrode antenna on 472kHz. I don't think it is any better than the short Marconi, but it certainly works pretty well, even with a short baseline of less than 15m.

Unique 472kHz WSPR spots this summer on TX

The number of unique spots of my 472kHz WSPR signal has now reached 15 and I have spotted 19 unique stations with my best DX being DH5RAE (995km) using the earth-electrode antenna last night.

Unique 472kHz WSPR spots this summer on RX

The earth-electrode antenna seems far more directional. Several stations orthogonal to the system did NOT copy me (or me them) overnight.
