472kHz overnight

Last night I went on 472kHz WSPR again overnight. Unlike earlier in the year when I spotted lots of stations and lots spotted me, I only spotted one station last night (a German) and just one station spotted me. At this time of year and through the summer I think I am wasting my time. Maybe I should chose a different band for WSPR overnight now?

Sunspots and 10m - Tues May 10th 2016

Solar flux is 88 today and the sunspot number 68 (K=4). The forecast for 10m propagation remains "poor", although there was F2 propagation on 10m WSPR yesterday.

It is just possible there is life on Mars.

My website and blogs

Every now and again I like to remind people of my main website and blogs. My main website (not updated too often) has details of my projects. The blogs get updated most days and are where I put news or things that are of interest to me.

Back on 10m WSPR

At about 0936z I resumed my 10m WSPR activity. It will take a few minutes before I am ready to give and receive spots.

Let us hope today is better than yesterday, which was dire here. At least the sun is shining, although this has nothing to do with Es!

There has been some work correlating some thunder activity with sprites and Es, but I don't know the details. Es is fascinating and there is still a lot to learn. May, June, July and August are the best Es months in the northern hemisphere with a much smaller peak December and January. Es can occur at any time though, to a lesser extent which is another good reason to use WSPR.

Years ago I remember getting into trouble with my mum and dad when I used the one domestic TV we had to hunt for Band 1 DXTV by Es.  In those days (1960s) you could see all over Europe on Band 1 TV in the summer months. On tropo I could always see the Band 3 819 line transmission (weakly) from Brittany. The antenna was totally in the wrong direction. On a 405 line TV (unmodified) there were 2 pictures side by side.
10m WSPR so far today
UPDATE 1142z:  Some Es on 10m WSPR. No F2 seen here.

UPDATE 1642z:  Much to my surprise, I exchanged spots with FR1GZ (9724km) this afternoon and spotted PU3WSF (10416km) this afternoon by F2.  I was not expecting F2 today.

Sunspots and 10m - Mon May 9th 2016

Solar flux is 83 today. Sunspot number is 42 (K=4) and the forecast for 10m propagation remains "poor".

I have yet to turn on my 10m WSPR. I shall probably use 2W TX on 10m and listen for others 80% of the time. Although F2 is very doubtful, Es is more likely on 10m today.

Declining swallow numbers - NOT amateur radio

See http://www.rspb.org.uk/discoverandenjoynature/discoverandlearn/birdguide/name/s/swallow/population.aspx

Certainly over here in East Anglia there are fewer swallows about than previously.  They have appeared on sightings in Devon, but I have seen very few so far. Swifts seem to be plentiful. I think I have seen as many house martins as swallows and that is just a handful. The RSPB says swallow numbers have been declining since the 1970s. As a harbinger of summer, I hope this is just a blip. Certainly we had a mild, wet winter but spring was late.

Gs only on 10m and 6m WSPR

On 6m WSPR I have been spotted by G4MLA (53km) and on 10m WSPR just G0LRD (25km) spotting me. No F2 DX and no Es here all day on 10m and 6m.

New rigs?

At the moment I am happy with the rigs I have, so I can wait to replace rigs.

At the moment the IC7300 looks a favourite over the FT991, but a decent FT817 replacement at the right price might fit the bill. All decisions on future investments are predicated on the price being right. I want dealers to make a fair margin, but I do not like being ripped off.  On the IC7300, dealers are making a mint out of early adopters who want the rig at any price. Later, the IC7300 price will drop.

I am awaiting Dayton to see if Yaesu really does replace the workhorse FT817. I have my doubts. As you know, 5-10W is quite enough for me.

Sunspots and 10m - Sun May 8th 2016

Solar flux is 87 today. Sunspot number is 51 but K=7. The forecast for 10m propagation remains "poor". With very disturbed conditions it is unlikely 10m will be any good today, although Es may liven things up. I have been on 10m WSPR and 6m WSPR since before breakfast.

UPDATE 0858z:  Unsurprisingly, no spots so far today! Maybe I'll spot, or get spotted by, some locals?

UPDATE 1454zStill no spots at all on 10m WSPR and 6m WSPR. Dire.I may go on 472kHz WSPR tonight.

ICOM IC7300 first reviews

Steve G1KQH has brought to my attention the first reviews on eHam of the IC7300.

Because of the wide front end filters, some have reported front-end overload issues. Software/firmware updates will not fix this as it is an inherent issue with wide front-end filters: nearby BC or amateur stations can swamp the front end and the rig sensitivity nosedives. As long as the overload does not occur it is a fine rig. I can see no good reason why this rig should be any worse than others that use sub-octave filters rather than narrow bandpass filters for each amateur band. Such designs are common nowadays in front ends.

I think sensitivity starts to collapse if the rig sees more than 70mV in the front end. If you have a nearby 1kW station operating in the same band, you could have problems. You might also have problems with multiple very strong BC band stations.

Although without 2m and 70cms, the European version does have 4m, which is good. I still just prefer the IC7300 to the Yaesu FT991. The price needs to drop though!

Eham reviews point to an overload in the front end:

10m F2 DX

PU3WSF (10416km) has been spotted on WSPR 2 times in recent minutes. I shall stay on 10m WSPR a bit longer in the hope that my own signal will reach S.America before the band dies out. Good to see some F2 DX on the band. At this time of year it is possible some of these openings are a combination of Es and F2 further to the south. There has been Es right across Europe all day on 10m.

UPDATE 2135z:  Nothing on 10m WSPR for over an hour now. I am staying on the band overnight, but think we have now seen the end of F2 and Es for the day.

FT817 replacement announcement?

If the rumours are to be believed, this month we may get an announcement at Dayton on a replacement to the FT817. Of course, it is entirely possible we will not!

In my view, Yaesu have "missed the boat" and should have launched such a product on the approach to the sunspot maximum rather than on the downward slope.Yaesu certainly need some "must have" features if they are to be as successful as with the FT817.

Plentiful Es on 10m

It will soon be time to get back on 6m as the Es season is really with us now. There is daily Es on 10m and I expect there will be Es openings on 6m too. I have not seen any F2 DX on 10m WSPR for a little while. It will be interesting to see if 10m opens to the USA this autumn. I think it will on a few occasions and certainly far less often than last year. Any USA 10m spots this autumn will be a bonus.

Stroke update - NOT amateur radio

2.5 years after my cerebellum bleed, I am still suffering. The worst are the poor speech, the profound exhaustion I suffer after most mental or physical exertion and feeling drunk all of my waking hours. To others I look fine. This is part of my frustration: everyone thinks I am fully back to normal, whereas I know different. It is very very hard to accept.
UPDATE 1528z: This afternoon I creosoted (actually a substitute these days) our garden shed. In the past this would have been a quick and easy job, but now it really exhausts me. There is still one side to do tomorrow as well as putting up a different bird box for next season.

Sunspots and 10m - Sat May 7th 2016

I have been on 10m WSPR since about 0715z (2W TX 20%, RX 80%).

Solar flux 89 today and sunspot number 56 (K=2). The 10m propagation forecast remains "poor". although withe the Es season we can expect some short-skip in 10m most days.

UPDATE 0908z:  Plenty of Es short-skip on 10m WSPR already, plus locals.  Today could be quite productive on 10m WSPR by Es. It would be good to see some N-S F2 propagation on the band too.

All quiet on 10m and 6m WSPR so far today

So far, there have been no spots on 10m WSPR or 6m WSPR. No F2 DX and no Es in evidence. This quite different from yesterday when on 10m there was a lot of Es about.

UPDATE 2116z:  EA1FAQ (1249km) was copied on 10m WSPR by Es earlier.  I have now QSYed to 630m (472kHz) WSPR for the night until after breakfast tomorrow.

RRS Sir David Attenborough - NOT amateur radio

The new polar research vessel has been named after Sir David Attenborough and not Boaty which was the outcome of a popular vote. I think this is the right decision.

Sir David Attenborough is a very famous UK naturalist with a world-wide reputation. Most of his life he has inspired others with a love of the natural world. Such a nice tribute.

See http://www.bbc.co.uk/news/uk-36225652 .

IC7300 groups

As you know, I quite like this new ICOM, but not the price. Unless a good replacement for the FT817 comes along I may buy one later when the price drops. Steve G1KQH has sent me details of some IC7300 Facebook groups.

People you no longer hear about - NOT amateur radio

If you live in the UK the names Peter Skellern and Richard Stilgoe may sound familiar. These pianists and singers were popular in the 1980s but I have not heard them or seen them for many years. As far as I know both are still alive, but they seem to have dropped from view. Perhaps they've had a change of career?

Change - NOT amateur radio

It probably happens to everyone and certainly does here. One go along a path that is little changed for years and then something happens to change things - like someone stops working, you move, or someone close dies. I guess we all have to accept that change happens. It is part of life. When it happens it comes as a shock, but one has to move on.

Sunspots and 10m - Fri May 6th 2016

Solar flux is 87 today. number is 55 (K=2) and the forecast for 10m F2 remains "poor" although there is now Es to liven things up in the Northern Hemisphere.

What a difference a day makes - NOT amateur radio

Yesterday I saw my first swift (bird) of the season. Today they seem to be everywhere!

This afternoon there were several feeding on insects high in the sky and there was a house martin high over our windmill. This morning we saw swifts in Newmarket and a number over our village  with a sparrowhawk.

In just one day swifts have gone from being rare to very common.

USA Presidential Election - NOT amateur radio

This is a "democratic" election and I am only observing from afar. Mind you, you need to have millions or billions to have any chance. Neither candidate fills me with joy but I am truly amazed that the republican candidate is so popular.

Come the outcome, the world may be a different place if the USA takes a more isolationist stance in the world again.

Here, in the UK, we are electing some local and semi-local politicians. Here in East Anglia we are just voting for a new Police and Crime Commissioner for which I have received no data at all, so I am not voting for this QUANGO which must be costing UK taxpayer's millions.

Aurora tomorrow?

There is a chance of aurora May 6th according to Dr Tamitha Skov on Twitter. I don't use Twitter much but get a daily email.

Radio Amateur's Exam

It is different these days but I took my RAE on May 13th 1966. Thanks to a link from Steve G1KQH, I can see the paper I took. I have to say I do not recall any of the questions today. It was a long time ago, HI.

Sunspots and 10m - Thurs May 5th 2016

Solar flux is 90 today. Sunspot number is 67 (K=2) and the forecast for 10m propagation remains "poor". Yesterday there was a brief Es opening, but no F2 DX.  Today is likely to be similar - I am not expecting great things, but hope to be surprised.

Daytime WSPRing today

The 10m WSPR beacon has been resynced to internet time. I have decided to stay on 10m and 630m WSPR all day today. 6m was a dead loss yesterday so I am not using 6m today.

UPDATE 0854z:  Overnight there we no 10m spots. 630m (472kHz) WSPR was more productive, although there were few stations copied and my best TX DX on 472kHz (5mW ERP) was just Holland. I have already been spotted in France and Finland on 10m WSPR and by G8LCO (58km) on 472kHz WSPR.

UPDATE 1226z:   Lots and lots of Es spots on 10m WSPR today - so many I have lost count!  On MF just spots from G8LCO.

UPDATE 1505z: 10m WSPR has been buzzing all day with 96 spots so far from all over Western Europe. A good day. No F2 propagation here, but made up with good Es.

4 May 2016

Overnight WSPRing

For a change I am WSPRing on 2 bands overnight.  Firstly on 10m, although I doubt anyone will spot me (!) and secondly on 630m (472kHz) where I am pretty sure I shall be spotted and will spot others.

Although I was on 6m WSPR all day until a few minutes ago, I spotted no-one and no-one spotted me. In all, 6m was a bit of a waste of time!

UPDATE 2115z: Just G4ALH and me G3XBM are shown as transmitting on 472kHz WSPR from the UK. There are quite a few more stations on RX and a few Norwegians on TX that I might copy.

First swifts spotted - NOT amateur radio

To me, swifts herald summer. Today, just before lunch, I spotted my first 2 swifts of the season high overhead. This is about the time I first see them here. There have been reports of swifts in Devon for a couple of weeks.

Hearing these summer visitors screaming in the evening sky brings real joy to my heart. Summer is nearly here!

Swifts have much narrower scythe like wings than swallows and house martins. They are late to arrive and leave early. They spend most of their lives on the wing. Years ago one crashed in the road and I was lucky enough to care for it overnight and handle it. The next day it just flew off!

FCC - so so S L O W .....wake me!

It is hard to believe just how slow the FCC is being over the release of the 137kHz and 472kHz bands in the USA.  Years have passed and neither band is released. The FCC is worried about interference to utilities. For goodness sake! Surely they could release both bands with a tight ERP level initially on a "non interference" basis? I moan about OFCOM but the FCC seems far far worse!

This is from the ARRL site...

"Meanwhile, the Amateur Radio community continues to await action on ET Dockets 12-338 and 15-99 that would spell out service rules for the new 2200 and 630 meter Amateur Radio bands. The FCC was expected to issue a Report and Order last fall. That subsequently got moved back to the first quarter of 2016, which also has slipped.
Regulatory provisions under consideration have included a possible notification requirement by some radio amateurs to utilities that operate PLC systems in that region of the spectrum, prior to their starting operation on either new band. Utilities use unlicensed PLC systems to control parts of the electrical power grid.
Earlier this year, the ARRL has asked the Commission not to adopt overly broad requirements to notify utilities in advance of intended Amateur Radio operation on the pending bands. The Amateur Service would gain access to 135.7-137.8 kHz (2200 meters) and 472-479 kHz (630 meters). Both bands have been used by numerous Experimental (Part 5) licensees, and the ARRL’s WD2XSH 600 Meter Experiment continues."

FCC - the world looks on and is amazed!! Wake up!! One cannot help thinking that the FCC is a pile of bureaucrats who do not understand radio. Please, release these bands in the USA.

Ossett UKAC Operators

I received a very kind letter from Robert G8BUN inviting me to become an Honorary Member at Ossett Amateur Radio Operators as I operate in the UKAC contests. This was very kind and much appreciated. My voice is not good and I am pretty limited in operating time on all speech modes.

10m and 6m WSPR

I went QRT on 630m (472kHz) WSPR about 50 minutes go and returned to 10m and 6m WSPR. Overnight on MF there were no great surprises with just DC0DX (467km) spotted. There are far fewer active TX stations on the band now.

UPDATE 0940z:  No spots yet on 10m WSPR and 6m WSPR.

UPDATE 1048z:  Still no 10m and 6m WSPR spots. 

UPDATE DF4UE (758km) spotted my 500mW 10m WSPR this afternoon. Es I assume.

Sunspots and 10m - Wed May 4th 2016

Solar flux is 91. Sunspot number is 57 today (moderate) and K=0. The propagation forecast for 10m remains "poor" again. Let's hope there is some Es to liven things up on 10m and 6m.

Dad - NOT amateur radio

Yesterday would have been my dad's birthday. He would have been 98 although sadly he died in his late 60s in 1987 from a heart attack. I can't imagine him being 98. He died young but he was otherwise healthy to his end.

I regret not speaking to him about his Pathfinder years in the RAF. There were brave young men on both sides in WW2. Dad did not like to speak about those days. Looking back he was very very brave.

The war years impacted him greatly and he was happy not to be reminded of them. The funny thing is if he walked in the door now it would seem so natural. There is so much I'd want to talk with him about.

If your parents are still alive ask them the questions before it is too late.

Sepura shares - NOT amateur radio

Although a long way below their peak, Sepura (SEPU) shares are rising again today despite a large fall in the FTSE 100 share index. At the moment they are trending upwards. You may recall that this was the company I worked for before I retired 8 years ago. How time flies!

See http://www.lse.co.uk/ShareChart.asp?chart=intraday&sharechart=SEPU&share=sepura

UPDATE 1500z:  At the moment these are 80.5p. They have been climbing for several days in a row now.

More from OFCOM

See http://stakeholders.ofcom.org.uk/?utm_source=updates&utm_medium=email&utm_campaign=1st-tues-0516 for more from OFCOM.

"Ofcom is committed to a thriving telecoms sector where companies can compete fairly and businesses and customers benefit from the choice of a broad range of services."

Yes. 

2m UKAC tonight

A reminder that the 2m leg of the RSGB's activity contest is tonight 1900-2130z. The 2m leg is the first Tuesday of the month. With warmer weather, we can expect more portable stations active on hilltops.

As usual, I shall be on with 5W SSB QRP and my big-wheel horizontal omni antenna. 200km seems about my maximum range, although I rarely stay on for more than 60 minutes as my voice is so poor.

Not having to turn the antenna is helpful. If the station is a decent strength then it is worth calling. I usually go looking for others which I find is the best tactic with QRP. This is usually productive although I keep missing others using the same technique such as G2XV who is quite local!

UPDATE 2100z: In the end I worked 9 stations with best DX 172km. See map below of QSOs. Heard but not worked were stations in Wales, Cornwall and France. I had to give up after 60 minutes because of my poor voice.
