6m - early June 2014

Not sure if this is "typical" but these are the unique WSPR spots on 6m today (so far) in both directions June 2nd 2014  Here using 1W ERP from a V2000 vertical triband antenna. Arranged in order of distance. Several stations spotted me many times during the day  (repeats not shown).

6m WSPR here today. Shows unique spots and arranged by distance
A good selection of Es and GDX on 6m today (so far - time now 1620z). Indeed the Magic Band!

UPDATE 1950z:   Out of the blue IK1NET (981km) with 5W is being spotted here at -20dB S/N - late Es. Magic band!

6m - 4X1RF spots me yet again with 1W ERP (3519km)

At 1308z 4X1RF spotted my 1W ERP WSPR on 6m for the 9th time this season. I assume it is Es and not single hop F-layer. I am amazed that 4X1RF can copy me so often. There was no sign of  intermediate distance stations. On 10m Chris regularly copies me when I am using low milliwatts. He has very good ears and must have a quiet QTH.  3519km is a great distance on 6m and I am even more pleased as my antenna is just a V2000 triband vertical fed with lossy CB coax. My FT817 is on the mid-power setting only.

I am still hopeful of transatlantic multi-hop Es propagation with WSPR. Patience! I must stick with 6m and keep everything crossed. If, as I have, worked K1TOL on CW in the past on 6m (summer 2007), then WSPR should certainly be possible as long as there are stations active on WSPR in the USA.  K1TOL has a BIG antenna farm but with WSPR more modest antennas in the USA should be fine.

Julian - G4ILO?

Just wondering if anyone has news on Julian?

It is nearly 1 month since his " One foot in the grave" blog was last updated and his health seemed to be failing back then. I have emailed Julian, but had no response from Julian or XYL Olga yet. Julian has been fighting a brain cancer for a couple of years. I hope he is still fighting it.

UPDATE 1431z:   See https://twitter.com/g4ilo/status/466514524707643392/photo/1 .  I hope Julian enjoys using the new radio. Good news.

6m Es - a good today

It has been a very good morning for 6m Es today with spots (both given and received) from across Europe and Morocco. SQ9SIM was spotted as early as 0742z and other reports continued throughout the morning.

It has also been good for GDX as well. G3WKW is the best so far at 134km  with low Doppler (-1Hz).

In all, a good day so far.

Health update (stroke)

You may (or may not!) remember that last September I was very ill and needed an operation on my brain for a bleed. I was discharged from hospital Jan 3rd 2014 and have been recovering at home, albeit slowly.

Today I had to attend a neuro clinic at Addenbrookes Hospital as an out-patient. They seem very pleased with my recovery, which is good news.  I may be driving again in the next few months.

They are doing a further MRI scan June 30th to see if my remaining giddiness when walking/turning can be helped. In all, it was a good outcome - nothing dramatic to report. Giddiness should continue to improve given time - just be patient - as the brain learns to cope and rewires itself.

Transatlantic 6m?

According to Steve's blog http://ve7sl.blogspot.ca/ there was transatlantic propagation on 6m today but here at least I copied nothing of this on WSPR.

I may have been unlucky but it was probably just that  there were no active WSPR stations where the propagation was reaching or my antenna is not good enough to catch weak, fleeting openings. I am leaving the kit running overnight just in case!

VE7SL's new blog

Take a look at this blog:
Hello Roger - just a note to let you know, and largely due to your inspirational postings over the past few years, I have also started a blog!

I'm sure you can identify with today's post as well.

Hopefully I can keep up the publishing pace as you have over the years.... I can see it will be a challenge.

Hopefully you will enjoy mine at least half as much as I enjoy yours :-)

Es on 6m at last - CN8LI

It was a long time coming today, but at 1648 CN8LI (2113km) spotted my 1W ERP 6m WSPR signal at -16dB S/N. This was the first Es report here in 2 days. It is teatime and Es tends to have a second peak at this time. Es is pretty reliable at this time of year, but the last 2 days have been unusually quiet.  I see I am copying him now on 6m.

6m unique WSPR spots so far today
UPDATE 1950z:  All quiet on the Es front here since 1702z. Just locals and G4VXE (136km) GDX. The locals are G4IKZ (18km) and G0LRD (25km) both of whom are using horizontal beams I think.  Not sure what antenna Tim G4VXE is using.

UPDATE 2045z:   G6AVK (78km) exchanging spots with me now. Signals around -24dB S/N  with considerable Doppler, so probably aircraft assisted GDX.

UPDATE 2115z:  I think the chances of more Es is receding. One drawback of WSPR is you can only copy the stations with WSPR capability. Sometimes there are few active WSPR equipped stations in a particular area. With CW/SSB stronger signals are needed but there are more active stations. It would be useful if there were more active WSPR stations on 6m in Africa and North and South America.


Doppler on 6m with G4IKZ (18km)

There must be more local flying activity at Cambridge Airport on Sundays (private flying?). On my 6m 1624z transmission there was 3Hz Doppler noticeable at G4IKZ - quite a bit when usually I get none at all. For a WSPR signal to be heard, the direct signal has usually to be much stronger than the Doppler shifted signal otherwise WSPR will not usually decode properly. Usually aircraft directions in flight have to be such that no Doppler is apparent for aircraft refection to work as a "path enhancer". I have noticed this with G3WKW in Hampshire on 144MHz WSPR over what is quite a long path. Get just the right flight direction and decodes occur. Otherwise, strong signals and no decodes. Sometimes G3WKW has been there for hours before he decodes on 144MHz.

G0LRD (25km) is just coming in on 6m at 1638z  at a strong -8 dB S/N with -4Hz Doppler, so his signal is arriving off an aircraft currently.

6m - quiet oday

Very quiet, so far, on 6m with just G4IKZ (18km) and G4VXE (136km) spotting my 1W ERP WSPR today as yet. No Es yet.

G4VXE' signal here has variable amounts of Doppler (up to 4Hz) suggesting aircraft reflections are involved. I think other modes (than WSPR) might be better with so much Doppler. The signal is often there but multiple and/pr large Doppler shifts can ruin WSPR signals, whereas other modes might be fine.

I did,very briefly, try 10m WSPR early this morning but QSYed back to 6m instead.

Sunspot count is 55 and 20-30MHz conditions are "normal". Let's hope for lots of multi-hop Es on 6m.

UPDATE 1625z:  No Es seen here yet still.  This is the second day this season without any Es DX signals coming through. Just G4VXE 136km GDX and local G4IKZ 18km.
