Return to 472kHz WSPR

Well, as I think the opportunity for 10m DX has now gone for the day, I have again QSYed down to 472kHz WSPR. I hope WSPRnet is working this evening and overnight.

It will soon be time to fire up the 6m WSPR station as the Es season approaches. There have already been hints of Es on 10m and soon it will be 6m. In the last two Es seasons 4X1RF (3519km) has copied my 1W ERP 6m WSPR signal several times, although I dispute the conventional multi-hop theory. I personally think this is (maybe) some sort of E layer tilt without an intermediate hop on the ground. I may be wrong.

Back on 10m WSPR

WSPRnet seems to be working again. I have been on 10m WSPR for about 20 minutes so far but I am only being spotted by local Jenny G0VQH who is 15km south of me. No DX yet.
QRP station. Currently on 10m WSPR
UPDATE 1615z:  Apart from a single spot this afternoon by OZ9QV (864km) nobody else at any range has copied me on 10m WSPR today. I have copied Norway and Sweden on 10m WSPR today so there is short-skip (Es?) around.  I'll leave the rig running a bit longer on 10m WSPR in case there are any S.Americans. In the coming months you sometimes get mixed modes on 10m with Es joining with F2 further south and some remarkable distances are possible.   USA DX by multi-hop Es on 10m and 6m is usually later in the summer. In past Es seasons I have copied USA, Caribbean and S.Americans by Es on 6m. I have only worked the USA once on 6m CW QRP but that was by Es. At the time 6m sounded like 20m!

WSPRnet - still broken?

Several times I have tried to enter the WSPRnet database, but without success. It looks like it is broken again. Without WSPRnet WSPR is no good, in my view.

EU referendum - NOT amateur radio

There is a poor quality debate on this matter. We vote on whether or not to remain in the EU in less than 10 weeks but the quality of the arguments is very poor.

The UK has looked towards the EU as a common market and never with a view to a political union. Many in Europe see it as a way to keep peace in Europe. At the moment I am still inclined to vote "IN" but the politicians here are certainly not winning hearts and minds on either side.

The debate needs to be more positive! All I hear are fear and uncertainty.

Late spring? - NOT amateur radio

A few months ago everything seemed to be early. We have seen daffodils in flower right through from late November. Some places have loads of daffodils in flower and even some snowdrops still. Yet, if anything, spring is late here. It is now way in to April but I have yet to see a swallow in this area. My laurel hedge is hardly growing. The grass has only been cut a few times. Odd. Yes there buds coming out, but spring is definitely not early here.

Sunspots and 10m - Sun April 17th 2016

Solar flux has dropped back a bit to 108. Sunspot number has fallen a bit to 51 (K=4). The forecast for 10m propagation remains "poor".

Conditions are not as good as yesterday when I managed to copy an LU briefly.

On the face of it, I should not expect much on 10m today. Of course, this assumes WSPRnet works today! Without it I cannot see where I am being spotted and others will not be able to see me spotting them.

16 Apr 2016

Back on 472kHz WSPR

As the storm risk seems to have passed, I have resumed 472kHz WSPR (5mW ERP 20% TX, 80% RX, earth-electrode "antenna") using the FT817 and homebrew transverter.

UPDATE 1922z:  So far only M0LMH (223km) has spotted me twice. He regularly spots me.

UPDATE 2000z:  Not for the first time, I find myself, yet again, the only UK station transmitting 472kHz WSPR.  I just don't understand why this is when transverters are easy and big antennas are not needed for WSPR.

UPDATE 2220z:  Now WSPRnet is playing up and won't load the database with me!  "Problem loading page". Wonderful. I'll stay on 472kHz overnight but without WSPRnet WSPR is not good. WSPR benefits from the internet feedback/reports that WSPRnet provides. One cannot be sure if reports up to WSPRnet are getting through. As many users have said, we'd be happy to pay towards a reliable service. Clearly the database and its maintainers are struggling currently

QRT - hail!

As there is a hailstorm currently, I decided to go QRT on all bands and disconnect antennas and PSUs. I am probably being over-cautious, but I can go on 10m WSPR another day. In the last few hours it has just been locals and no DX on 10m WSPR.

UPDATE 1700z: See http://www.lightningmaps.org/realtime?lang=en. At the moment the maps show thunderstorms to the north of here. I may go on MF later.

UPDATE 1848z:  As the nearest storm is in the Leicester area, I think it is safe to resume MF WSPR transmissions.

10m WSPR DX

LU8EX (11208km) was spotted here on 10m WSPR this afternoon. Apart from this, spots were local apart from G8VDQ (93km). 

As I have said many times before, WSPR is the ideal mode to spot these brief 10m openings. On SSB it is unlikely anyone would have even realised the path to Argentina was open today. And don't forget, the Argentine station was only running 5W QRP.  With WSPR, only QRP is needed.

There is still a chance of further DX on 10m WSPR, so I shall remain on until after dark.

SteppIR antennas

The designer of the SteppeIR yagi is at W&S next week according to Southgate News.

I am not a great fan of big amateur antennas, but I understand they will appeal to some. As you know, my "thing" is QRP and small wire antennas, but each to their own. What appeals to me is different to what others judge important. There is room in our hobby for many different interests.

See http://www.southgatearc.org/news/2016/april/steppir_at_w_and_s.htm

Broadband - NOT amateur radio

73.72Mbps download speed tested over wifi by Ookla on the cheapest Virgin Media package. Can't complain.

10m WSPR - just a local so far

G4KPX (14km) is the only station to spot me so far on 10m WSPR. This is disappointing as I was expecting more by now. I shall be on 10m WSPR until dark and hope to spot, and be spotted, by more stations including some DX.

UPDATE 1306z:  Still just the single local spot on 10m WSPR today.

ON4KST chat for skeds

Quite a few people us this to arrange skeds on VHF, UHF and microwaves. It is also used for some LF/MF skeds too. There are different forums for different bands.

See http://www.on4kst.com/chat/start.php .

Sunspots and 10m - Sat April 16th 2016

Solar flux is a respectable 113 today and the sunspot number higher at 69 (K=1). The forecast for 10m propagation remains "poor" but I think today will be a good 10m WSPR day.

UPDATE 0924z:  No 10m WSPR spots yet, although it is very early.

15 Apr 2016

RSGB videos

The RSGB has produced some very good videos designed to introduce the hobby to those "outside" it or to explain its vast possibilities to those already in the hobby.

For example, see https://www.youtube.com/watch?v=SH9OtgAcV6g.

Well done!

EU referendum - NOT amateur radio

It is now 10 weeks until people in the UK hold a referendum to decide whether or not to stay in the EU. At the moment I am voting "IN" but I have been appalled by the campaigns so far. What comes across are fear and uncertainty. No-one seems to have anything positive to say! I hope this changes.

FTSE 100 - NOT amateur radio

At the moment the UK share index, the FTSE 100, is down about 0.48% today, no doubt spooked by Chinese growth slowing. The world economy is not that healthy and we could well be heading for another downturn. If the end result is a fairer world this would not be a bad thing.

Rallies in years to come?

The high streets are changing. Have you noticed that there are far more coffee shops and charity shops and far fewer bookshops? This is because of us.

I wonder what radio rallies will look like in the future. Rallies are not my scene really, but I have been to a few over the years. There seem to be fewer trade stalls nowadays and more stalls that are not amateur radio related. As the average age of radio amateurs increases, fewer people will attend and some will stop. The GQRP rally at Rishworth ends this year, no doubt because of the average age of attendees. No, radio rallies will soon be a thing of the past if we are not careful.

My concerns about radio mags and adverts have been shared before, but our hobby is likely to be very different and soon. What can be expected are fewer magazines, fewer adverts, fewer products as the market shrinks.  Our hobby has a problem on many fronts due to an ageing population. We ignore this at our peril.

Back on 10m WSPR ...and some DX

FR1GZ (9724km) has been spotted on 10m WSPR and I have been spotted in Italy. Italian stations are also being spotted here.  My return to 10m WSPR is proving worthwhile.

UPDATE 1345z: CX2ABP (11127km) in Uruguay has been spotted several times on 10m WSPR this afternoon.

UPDATE 1915z:  In all CX2ABP was copied 4 times up to 1808z. What is interesting is the large drift (Doppler?) on the signal. The most probable explanation is that the layers near the equator were moving (spread F?), hence the Doppler.
UPDATE 1920z: I have decided to go QRT on all bands to minimise the storm risk.

Sunspots and 10m. Friday April 15th 2016

Solar flux is 112 today and the sunspot number 46 (K=1). The forecast for 10m propagation remains "poor".  Despite the forecast, I have "good vibes" about 10m WSPR today.

Radio active?

In a few minutes I am going to assess the risk of nearby storms and venture onto 10m WSPR for a few hours if the danger is low. I know there is a risk later but there maybe a window of a few hours. Although I do not like storms nearby, I miss not being active on the radio. I see than I have been on JT65 and JT9-1 far less than I intended this year. Still we have only had 3.5 months, so plenty of time left this year.

UPDATE 1000z:  The risks look low with no nearby lightning shown on the map, so I shall go on 10m WSPR shortly.

Thunder and lightning - NOT amateur radio

For the last 20 minutes we have had thunder and lightning here. According to the time between the lightning and thunder it was about 1 mile away. My radios and PC will remain disconnected. Looking at the map linked below it seems to be tracking NW the worst may now have passed. It remains very dark outside and we can still hear thunder.

See http://www.lightningmaps.org/realtime?lang=en

UPDATE 1830z:  Although the storm risk seems to have passed today, more storms are possible tomorrow, so I may leave things disconnected. 

Innocent until proved guilty? - NOT amateur radio

A recent case has arisen in which a man found guilty of a serious crime has professed his innocence to a number further charges. Mud sticks and innocent people get tarred even when they are later proved innocent.

Personally, I think no-one should be named until they are proved guilty of any crime. The law is an arse if innocent people are found guilty by the mob. I can think of several examples where lives have been ruined, wrongly. If guilty, the courts will find this and justice will be done.

Lightning maps

See http://www.lightningmaps.org/realtime?lang=en .

I find these maps very useful as they give advanced warnings of approaching storms. Even when storms are some way away you can get surges that can damage equipment. With approaching storms I tend to disconnect radios and PCs and unplug antennas and mains connectors.

Years ago, a friend at work got struck (his house) and I have always been a bit wary since. Thunder and lightning can be very nasty.

Sunspots and 10m - Thurs April 14th 2016

Solar flux is 112 today and the sunspot number 41 (K=3). The forecast for 10m propagation is yet again "poor".  It is unlikely I'll be on the band today as there is a risk of thunder and the band will be closed for DX later. I may go straight to 630m after dark.

472kHz last night

PA0RDT (243km) was best DX on TX on 472kHz WSPR last night. In all, three different stations spotted my 5mW ERP. It was a disappointing night on the band.

I have now gone QRT on all bands as there is thunder forecast. I may resume operations later when the threat is no longer with us.

13 Apr 2016

CDARC 2m FM Net

This evening at 1900z I came on the 145.550MHz Cambridge Club net. I had a long chat with M0SND (Waterbeach) who gave me a 59+50dB report despite me running QRP to an omni-vertical. Alex is 92 years old  and was a regular on our Monday 2m net. It was good to talk with him again.

At one time (early 1970s) I was on the committee of the Cambridge club. It is some years since I last went to the club. I am not keen on driving in the dark these days.

See www.cdarc.co.uk  .

Return to 472kHz WSPR

We have been out most of the day at Felixstowe Ferry for a walk next to the sea and a lunch of fish (fresh) and chips at the old fashioned cafe that has been there since 1958.

I have been on 472kHz (630m) WSPR since 1936z. Only spots by M0LMH (223km) so far of my 5mW ERP, but the evening and night are young.

UPDATE 2100z:   LA8AV (1035km) is the best DX on RX so far tonight on 472kHz WSPR.

Steve G1KQH - NOT amateur radio

Steve did look for deals on eBay yesterday and found the Bluetooth smart watch for a little over £4. See yesterday's post. I do not understand how they do it for the price and ship it half way around the world.

Steve also sent me a link in which you can check MOT history.
See https://www.gov.uk/check-mot-history

40m WSPR overnight

No great DX last night with only European spots given and received overnight. On previous 40m WSPR outings I have been copied in North and South America and Australia. No such luck last night!

Sunspots and 10m - Wed April 13th 2016

Solar flux is 113 today. Sunspot number is 34 (K=4) and the forecast for 10m propagation is again "poor".

As there is a chance of thunder, I am not currently active on any band at present. I shall review the situation later.

12 Apr 2016

70cm UKAC

As usual, I entered the RSGB's monthly activity contest for 70cms using 5W pep and my 2m big-wheel antenna. I only stopped on for less than 1 hour because of my poor voice. 5 QSOs were made as shown on the map. Considering the QRP, poor antenna and my limited time, I was quite happy with the results.

QSY to 40m WSPR

After another disappointing day on 10m WSPR, I have QSYed to 40m WSPR for the evening and overnight.

UPDATE 1840z:  UA1ASB (2042km) is the best spot of my transmissions this evening so far. Plenty of spots given and received on 40m WSPR.

That EU referendum - NOT amateur radio

See http://www.bbc.co.uk/news/business-36024492

As a "floating voter" in the coming EU referendum I am not impressed by the £9M government publication going to each home and the negativity of the "IN" campaign.

Surely if staying in is a good thing, there are positive messages, not just more negative comments, that can be shared? My instinct is to vote "IN" but I may well change my mind.  I have a brain and intend to use it. I need to hear positive reasons to stay in the EU. All this negativity is counter-productive.

UPDATE 1850z:  I got this in the last hour. Apparently, if you return the leaflet to the freepost address, the Conservative  Party gets billed for the postage:


Another stroke after-effect

At one time, I just looked at a word and knew if it was wrong. These days I really struggle. As an example, on one of my other blogs I used the word "daffodils". I have to admit that I had to look up the word to see if it was daffodils or dafoddils. I am sure that this lack of seeing spelling errors is yet another post-stroke after-effect. It is more of an inconvenience than a real handicap, but I can see that this has changed. Strokes and brain injuries are odd things. Even 2.5 years after it all happened it is still causing me real problems.

BeoFeng Dual Band Transceiver for £18.99 (or lower) with free postage!

See http://www.ebay.co.uk/itm/BaoFeng-UV-5R-136-174-400-520-MHz-Dual-Band-DCS-DTMF-CTCSS-FM-Two-Way-Radio-/252233483100?hash=item3aba49835c:g:6RAAAOSwL7VWhdxu

Some of the prices for new amateur radio gear is just incredible. At these prices how can anyone make a profit? This is shipped from the UK too.

UPDATE 1235z:  OK, I give up! I have just seen it available even cheaper (£15.75) on eBay!! See http://www.ebay.co.uk/itm/BAOFENG-UV-5R-Dual-Band-UHF-VHF-Two-Way-Ham-FM-Radio-Speaker-Mic-Walkie-Talkie-/262371437743?hash=item3d168e6caf:g:JXkAAOSwJQdW-zkK
 No doubt Steve G1KQH will find the lowest price ones! Once he reads this he will be "on the case".

UPDATE 1246z: Or maybe a smart watch with Bluetooth for just over £7? See http://www.ebay.co.uk/itm/Bluetooth-Smart-Wrist-Watch-Phone-Mate-For-Android-IOS-iPhone-Samsung-HTC-UK-/172150503333?var=&hash=item2814f837a5:m:mIJ9EQ_TPg5B29hjQ8cDS_Q

Alibris amusement - NOT amateur radio

Each and every week I get an email from Alibris with so much off for a very limited time. Do they think I really am stupid? These offers are so often and so regular that I doubt anyone buys from them at the un-discounted prices. I hate these ploys. It is years since I have used them. Their sad marketing tricks do not impress me one bit.

10m WSPR and 630m WSPR overnight

As yet, no spots on 10m WSPR, although it is still early in the day. With solar activity up a bit I am hopeful of some 10m WSPR DX later, although 10m can be fickle and the forecast is "poor".

630m WSPR, last night was disappointing with no new stations copied or copying my 5mW ERP.  It will soon be time to switch to 6m for the Es season.

It is possible some short skip will liven up 10m and 6m. The main Es season in the northern hemisphere is May, June and July but Es can occur at any time. WSPR helps find these brief openings!

QRP

Oleg sent out a reminder about the Tuesday 0900z net on 14.060MHz but I have only just got on the PC, so I was unable to send out a reminder.

Generally there is QRP on, and close to, the internationally agreed QRP frequencies on each band. If you are after QRP QSOs then these are always the best places to look first. If you call a QRO station, the chances are they will not realise you are using 5W or less. The difference is only a few "S" points, so save the Earth's resources and only use the power you need. Besides, QRP operating is real fun.
