Back on 6m and 10m WSPR

For the last hour or so I have been back on WSPR on these bands. Just G4IKZ (18km) on 10m WSPR  and G0OQK (98km) on 6m WSPR. No early Es.

Refugees - NOT amateur radio

I am sick and tired of "our" position here in the UK on refugees. We should be working to HELP these desperate people, not treating them as scum.  Those fleeing wars and conflict need our kindness and care, not hate and indifference. We should be working with the rest of the EU to solve this crisis.

Oh by the way we, here in the UK, sell arms to the value of £5 billion to countries on the human rights "black list" of countries. See https://news.vice.com/article/the-uk-is-going-to-send-billions-in-arms-exports-to-countries-on-the-human-rights-blacklist . We are partly to blame for the worse refugee crisis in Europe since WW2.

QRT on all bands

As 6m and 10m have been poor today, I have gone QRT on all bands until the morning. I should be back on 10m and 6m WSPR after breakfast.

No early Es on 10m and 6m WSPR

There is no sign, yet anyway, of Es on 10m here. I shall turn on the 6m station shortly as this was off overnight. Just spots from local G4IKZ (18km) on 10m WSPR so far today.

UPDATE 1222z:  Still no Es seen here on 10m WSPR. The same too on 6m WSPR  where the only station spotted is G0OQK (98km) by tropo and aircraft reflection. Definitely end of the Es season!

UPDATE 1724z:  Still no Es on 10m or 6m WSPR here. No F2 DX here yet on 10m WSPR. A bad 10m day.

2m Big Wheel

Steve G1KQH has requested that I blog this to say how it performs.

As my health is still not good I bought mine from Wimo in Germany, but with some aluminium tubing, some insulating material and a little skill, making your own should be straightforward. Being in the EC, imports from Germany already have VAT applied and there was no import duty. However the Wimo big-wheel, although well engineered, was not cheap. As purchased, it comes partly assembled for 2m but the 70cm version is sold ready made. The well packed antenna arrived from Wimo in Germany in about 7 days. There were instructions in German and English.

My 2m version had to have the elements attached. It is very easy to miss the screw holes and not assemble it correctly. There were no instructions for the mounting bracket, but this was straight forward enough. Overall, even with my poor health assembly took about 10 minutes

When first installed on my temporary mast my SWR (as indicated on the FT817) was rather high. Carefully bending the elements and adjusting the orientation of the matching stub brought this way down and I left it with 1-2 blobs showing on the FT817. The gain is claimed as around 3dBD horizontal.

In use it proved great: I worked all the stations I had previously worked on the halo (and others) with better reports in last night's 2m UKAC session. Best DX was 181km. In 52 minutes I worked 10 SSB stations. I was using 5W pep from the FT817. The antenna is fed with a length of RG213 (9mm diameter) coax. Not having to rotate the antenna is a great advantage. I received stations in Belgium and Holland, but did not work these in the short time I was "on air". I am sure that a lot more squares would have been worked had I stayed on for longer.  What was nice was being able to hear the activity all around and not having to turn the antenna at all. Ideally it should be used in conjunction with a beam, but the big-wheel suits my style of casual operating well.

Would I recommend a 2m big-wheel? Yes!

Sunspots and 10m - Wed Sept 2nd 2015

Sunspot number has hardly changed and is 49 (K=2) today. As we are now moving towards autumn we should be seeing some 10m F2 propagation on WSPR as long as there is activity! 10m propagation is expected to remain "poor" today.

2m UKAC contest this evening

If I can do a temporary erection of my 2m big wheel using the long 2 inch pole just laying next to the window, I may give tonight's 2m UKAC a try. The big wheel, fed with low-loss coax, should be almost 1 S point up on the halo I used last month. It would also be a chance to try out the big-wheel before it is permanently erected on the end of the bungalow. I have been kindly offered help with this, more permanent, erection.

2m big-wheel - temporary erection

UPDATE 1702z:  I have managed to get my big-wheel up in the air temporarily so (assuming it does not fall over!) I should be able to give it a run during the 2m UKAC contest this evening. I am copying the GB3VHF and PI7CIS beacons but the SWR seems a bit higher than I was expecting. Performance is better than the halo, but I am not sure by how much, maybe 0.5 S points or about 3dB? Tomorrow I might see if I can reduce the SWR a bit. It is not bad, but could, and should, be lower. In its final position, above the window on the LHS of the photo, it should be at about the same height. Once erected, I shall be unable to make any adjustments.

UPDATE 1750z:  By altering the position of the stub and and bending the clover leaves very slightly the SWR improved. I think it can be improved more, tomorrow.

Stations worked in 52 minutes in the 2m UKAC this evening with 5W SSB

UPDATE 2035z:  The big-wheel, on its temporary pole, performed very well with 10 QSOs (best DX 181km) with just 5W pep in 52 minutes. Not having to turn a beam is so much better. I may well try this in the 2m contest this weekend, for some of the time before my poor voice says, "STOP!!".

No Es on 10m or 6m WSPR all day, so far

We are definitely at the back end of the Es season now. So far today there has been no sign at all of any Es propagation on either 10m or 6m WSPR. I shall stay on 10m WSPR overnight but will probably go QRT on 6m before 1900z.

UPDATE 2237z:  No 10m or 6m Es seen all day here. Roll on autumn conditions!

Sunspots and 10m - Tues Sept 1st 2015

Sunspot number is 50 today (K=2) and 10m propagation is again expected to be "poor".

Yet another stroke artifact - NOT amateur radio

Yet another stroke artifact seems to be an inability to spot spelling mistakes as easily as before. Sometimes it takes me ages to think how a word is spelt (or is it spelled?). Often it is hours (or days) later that I notice the mistake! In writing this short piece I made at least one mistake whilst writing it.
