G8JNJ/A on 6m WSPR

All very quiet on 6m so far today apart from the usual G4IKZ (18km)  spots. Then at 0914z G8JNJ/A in IO90hx (184km) spots me weakly at -29dB S/N. No Doppler, so aircraft reflection less likely, so presumably tropo?

Sunspot count 126 and 20-30MHz forecast to be "normal" again, so 10m propagation is, again, anyone's guess. Still waiting for first Es openings today on 6m.

Mark Thomas (Channel 4) Secret Map Of Britain

Maybe, like me, you had not seen this YouTube video before. Mark explores some of the places left off some UK maps to preserve their secrecy. In many cases the information is readily available by other means. Apparently the number of places left off maps runs into thousands (at the time the film was made) and yet many places which you might expect to be hidden are not. Bizarre.

At one time Devonport Docks (Plymouth) were blanked out from 1:25000 scale OS maps. Not sure if this is still so. Looking at the map it was very obvious this was a secret place and no doubt a prime Russian target back in the Cold War.  Blanking out the area drew attention to it - the reverse of the intention. Doh!

I make no judgments, just sharing an interesting YouTube link.  I assume sharing this publicly available YouTube video does not contravene any state secrets. Mark filmed this for Channel 4 TV here in the UK.

Yaesu and that (never coming) FT817 replacement

Yaesu amaze me. They would have a near certain HUGE market for a more up-to-date version of the FT817. We punters have been waiting YEARS and it has still not appeared.

Instead they mess about with VHF/UHF digital radios. They could probably re-use the FT817 mechanics and just update the insides. The FT817 is a good radio, but it is 14 years old and there are many features it could do with. The FT817 and FT817ND must have sold over 500000 worldwide! The window for releasing a new version is rapidly closing as the sunspots fade.

My wishlist (just some features, no particular order)
  • LiIon battery pack
  • Auto ATU
  • Speech processor
  • OLED display
  • DSP noise reduction 
  • 70MHz
  • 1296MHz
None of these should be hard (or expensive) for Yaesu to develop. So just why have they not done this?


6m - Tuesday May 20th - some lunchtime Es

A very uneventful morning so far on 6m WSPR with just the usual strong reports from Nick G4IKZ (18km) on the far side of Cambridge. No Es yet, although it is early in the day. At  the moment, 6m is very slow going with LOTS of WSPRing during the day for (maybe) a fleeting opening. At least with WSPR you can do something else whilst monitoring and TXing.

Maybe the 6m band will open up later?  Sunspot count is 130 and 20-30MHz forecast to be "normal". Again, 10m propagation will be whatever. 6m will remain "sporadic" with lots of white noise. It would be good to hit a period of 6m Es that lasts all day. It is early in the season I guess. On 6m I'd be very lucky to see any real long distance DX.


UPDATE 1435z: Well patiently 6m WSPRing paid off with spots from Morocco by CN8LI (2113km) late lunchtime today (best -5dB S/N at 1404z).  With that report, he would have copied me if my ERP was just a few mW, given a quiet RX environment his end.  This is a problem nowadays: often the RX noise floor can be quite bad, especially in towns and cities with so much RF noise pollution.   CN8LI was also spotting me (more weakly) at teatime (1612z) - see table above. 1W ERP seems plenty for Es.

UPDATE 1930z: No further Es in evidence here since CN8LI at 1612z. Think that is it for today?

East Cambs 2m Net

Every Monday evening at 8pm UK time there is a net on 144.575MHz (note 144.575MHz , NOT 145.575MHz) FM in East Cambridgeshire. The net started some years ago as an AM net on 144.55MHz but one joiner had no AM, so we went over to FM, vertically polarised.  Usually there are 3-4 people on the net and others are very welcome. Discussions are wide ranging and cover all sorts of amateur radio subjects.  Usually one person has a query and the others try to answer the question. Occasionally we do on-air experiments too. We always finish by 9pm latest and quite often earlier if we run out of topics.

6m WSPR today - very quiet

A full day on 6m WSPR and only G4IKZ (18km) and G6AVK (78km) spotted me. No Es noticed here at all, all day long. Perhaps tomorrow will be better? That is the nature of Es - it is sporadic! It is interesting seeing what GDX possibilities exist. On 6m, 4m and 2m I suspect WSPR is not ideal inter-G because of aircraft Doppler.

ARRL - thank you (in the end)

7 days and 5 emails later my ARRL user name has finally been reset, so I can now access the ARRL site once again with my 1 year paid subscription. Why did it take so long? Goodness only knows. 7 days should have been just a few minutes.

I wanted to say something good about the ARRL but this total fiasco has rather left me speechless and lost for words to adequately say how I feel.  They should have done better - NO excuses.

At least I can again access the ARRL site. As far as I can tell the site was muddled by having had a 90 day free trial membership before becoming a fully paid up member. Why it took 7 days to sort, goodness only knows!

ARRL:  1/10 for effective member support. I'd wanted to say something nice but just cannot,honestly. I just hope others fare better than I did.  Why cannot you reset your user name online? Their online help is flawed if you lose you user name as I did in a PC crash.

In my experience the RSGB does a much better job at supporting its members.

6m update

No 6m Es since yesterday (yet) and just G6AVK new in the log, both ways, last night at 78km. Today lots of good spots again from G4IKZ (18km) but nothing yet from Europe or elsewhere on 6m.  Sunspot count 138 today and 20-30MHz forecast is"normal" so 10m is anyone's guess. Of course on 6m I am mainly looking for Es.

Lesser Chirpy - a VERY simple 10m transceiver

This design is a couple of years old and evolved from Chirpy. Unlike the original design, chirp on 10m is negligible. This design really works and gives credible results on 10m with just a handful of parts. Sensitivity could be better  with a few more parts, but not this simple!

See https://sites.google.com/site/g3xbmqrp3/hf/chirpy .

6m homebrew SSB/CW transceiver and the Sixbox

6m is an ideal band for experimenters. Local coverage is very good, Es DX possibilities in spring and summer are good (strong signals out to about 1500km) and the frequency low VHF so less layout critical than 2m.

I am always on the lookout for interesting ideas for 6m QRP rigs and just noticed this one from Japan. This amateur also manages to package his designs so neatly: they look like factory-made products.  See http://www.qsl.net/7n3wvm/xcvr-6m.html for a neat 3W QRP SSB/CW transceiver.

For a really simple AM transceiver design see my Sixbox on my main website. Ideal as a basis for further design for local natters. Very simple concept that works.  On the main website click images and schematic for clearer versions.

See also http://www.pg1n.nl/articles.php?lng=en&pg=145  for a list of 6m designs. His website also has lists of designs for other bands.

6m update

After a very brief Es opening to Italy this afternoon, all is again quiet on 6m WSPR. I have left the kit running but only G4IKZ is spotting me at the moment.

6m is an even more fickle band than 10m and even more challenging because of it. At the moment Es is starting to wake up the band, although stations further south (around the Med.) have been able to work remarkable distances by TEP in recent weeks. Also,  there has been 6m TEP between Japan and Australia.

ARRL website - crap!

Don't lose your user name or ID or you may never get in again!

I was a 90 day guest member, decided to join for one year on a special offer. Lost my user name (PC crashed) so asked ARRL for help getting back in to read QST etc.. 6 days later (6 DAMN days!!!!) and not a single reply from ARRL. What a load of tossers!  They have now had 3 emails.

Next year, it is very unlikely I shall rejoin.  This level of member support is totally pathetic. I am not at all impressed with their "help". If you lose you user name it appears the on-line help does not help at all, but (so far) neither does emailing ARRL!

How can a national society's website be totally inaccessible to paid up members? How come ARRL is so bad at supporting its members?

10m and 6m

Sunspot number 146 and the 20-30MHz forecast is "normal" so it is anyone's guess what 10m will be like today.  I am now monitoring (and TXing) on 6m WSPR but all is very quiet on that band so far with just locals G4IKZ and G4KPX copying me so far, and very well. Things on 6m (and 10m) can rapidly change of course and that is half the fun.

On 6m there is a decent level of  European activity, so if  Es appears I should be spotted. 6m is a nice challenge right now. On 10m I pretty well know who will copy me when the band opens by F2 and 6m QRP is a good new experience on  WSPR.  Spots from 4X1 were a real surprise a few days ago.  6m at the moment is likely to be mainly Es but there is just a chance of some F2 layer propagation.

UPDATE 1535z:   IK1WVQ (1084km) spotted at -8dB S/N at 1528z on 6m WSPR. Some Es about.  A little later he was +9dB. Typical Es.

South Sands - Salcombe (in danger)

See http://qss2.blogspot.co.uk/2014/05/salcombe-south-sands.html.

Not amateur radio, but a concern of mine. Salcombe, Devon is where I originally came from.  It is still dear to my heart as it is a seaside town in grave danger of being ruined by profiteering developers and rich playboys with far too much money and in many cases very little brains. Salcombe is losing its heart and soul. Prices are such that locals are being priced out by second home owners, with many homes empty much of the year.

The development linked above is just one such development. Planners are playing their hands very close to their chests, suggesting they may want to over-develop the site and ruin the sea end of a beautiful valley.

If you have an interest in ensuring the long-term well being of this pleasant seaside town please check the plans next week and use your democratic right to influence the plans.

Salcombe was the home of my mentor and CW instructor Les G4PJ.  I could copy him on 160m 4 miles away on a crystal set.

6m DX?

G4IKZ, G4KPX and G0LRD on 6m today so far. All locals. No Es seen so far today but it could all change very quickly,  so will leave the kit on. It would be nice to see some more EU stations appear by Es. It would be even better to see some North Americans by multi-hop Es but this is more probable later in the season and it depends on some N.American 6m WSPR activity!
Unique 6m spots today - all locals and no DX today.

16 May 2014

GDX on 6m

During the day a few more G stations have been spotted on 6m WSPR as well as the great DX to CN8 and 4X.

As well as lots of spots from G4IPZ I have been spotted by G4KPX, G0LRD (all locals) and earlier this afternoon by G1IDZ in IO82tc at a distance of 183km. G1IDZ is real GDX at a great range. I would expect this station also had a vertical antenna?

Israel on 6m - 3519km with 1W ERP

After earlier success on 6m QRP WSPR (1W ERP) with CN8LI imagine my delight to be spotted seven times this afternoon on 6m by 4X1RF (3519km). If Es, this is multi-hop but there were no reports from nearer in Europe, so it could be single hop F layer? Again, the antenna is the V2000 vertical fed with quite lossy coax. 6m - magic band!
4X1RF 6m WSPR reports - 1W ERP 3519km!
G4IPX was also copying me at just 14km.

Morocco on 6m

Just when about to give up (for now) I see my 1W ERP on 6m WSPR has been spotted in Morocco by CN8LI at a remarkable +2dB S/N at 1252z.. Distance is 2113km. I shall leave the 6m gear running! Propagation will have been Es.  For Es, a V2000 vertical is an effective omni antenna. Mine is fed by a length of  RG58 cable, not exactly low loss too! The FT817 is on the "3 blobs" setting as on 10m which is about 2.5W into the feeder.

CN8LI's 6m spot of me today at 1252z

On 6m again this morning

Conditions (tropo) are up on 2m today with the Kent 2m beacon measuring strongly on the FT817ND's S-meter. Usually, the S-meter does not even move. I don't know if tropo has as great an impact on 6m (I think not) but so far today just the usual good reports from G4IKZ (18km). Later, I hope to catch some sporadic-E (Es) propagation or even some GDX by 6m tropo, or more distant "semi-locals".

G4IKZ's first report was at 0648z when I first turned the rig and PC on today.  Reports vary by about 6dB but this could be G4IKZ rotating his beam rather than propagation. I'd be surprised if propagation varied by 6dB over such a short path. The other explanation is my local noise floor is increasing as the day goes on and more local appliances are activated? Another explanation is aircraft reflections from small planes over Cambridge? Maybe there is more activity today. That could explain the Doppler on my signals too.

Otherwise all very quiet  here so far at 1000z. It is a bit early in the day for Es which usually peaks around lunch and teatime unless the band is really humming.

Currently, I am not monitoring 10m, but the sunspot count is 130 and 20-30MHz propagation forecast to be "good", so HF should be good.

15 May 2014

6m update

I have been on 6m WSPR since lunch time and have received 52 reports from G4IKZ 18km west of here. So far, no GDX copied, no other spots by UK stations and no sign of Es reports. I'll leave the kit running for a short while but will then close until after breakfast tomorrow.  Maybe tomorrow will bring some more interesting reports?

The G4IKZ reports have been very useful -they prove I am getting out OK and on frequency - but it would be good to receive a few more stations and to be spotted a bit further afield.

Quadcopter drones controlled by wi-fi

On my other blog I mentioned the latest small drones produced by Parrot.

The prices don't seem to have fallen as I had expected. See http://www.pixmania.co.uk/high-tech-gadgets/parrot-ar-drone-2-0-elite-edition-sand/21869578-a.html?ectrans=1&ef_id=U2AUYQAABW1F-nsq%3A20140515154655%3As&gclid=CMvR8aajrr4CFckBwwod_CsA5A&merch=1&srcid=11270 as an example. Prices seem to be £230 upwards.

For me, this is still far too expensive to consider, even though being able to "drive" it from an iPad is fun, as are the on-board cameras which look forwards and downwards. It is like being a real pilot. I saw one in use at a BBQ a few years ago and it was great fun. Even that one got lodged in a tree as I recall.

At those sorts of prices, I'd be far too worried about it getting stuck on a roof or in a tree and that would ruin the fun. Also, apart from the very latest lightweight designs, you'd have to be very careful near people, pets and vehicles.

On the Argos website quadcopters are available for around £55, but I've got no idea about the functionality of these.

Lightning and solar activity

Dr Steve Collins of Sheffield University has pointed me to this fascinating link on the BBC website:
http://www.bbc.co.uk/news/science-environment-27406358 .   It shows  how solar activity and lightning are linked, possibly allowing a means of predicting future lightning activity.

6m WSPR

As it is the Es season, I have moved up to 6m WSPR, but so far only G4IKZ is spotting me at 18km.  I think Nick uses a 6m horizontal Moxon antenna yet, despite cross polarisation (I am using a V2000 tri-band vertical) he is giving me +4 to +7dB S/N.  I am hopeful of some Es and GDX later. As of 1540z 20 spots from G4IKZ, but nothing else seen. I have spotted no-one, near or far.

With the same antenna and feeder I have worked all over Europe, N Africa and even into the USA with real 6m QRP SSB or CW. With 1W ERP WSPR I should be able to reach all of these areas and more given WSPR activity and good Es conditions.

10m - less good today?

Yesterday 4X1RF had spotted me 14 times by this time whereas today he spotted me just once.It may be that he is concentrating on 6m instead or an indication of less good 10m propagation on 10m?  There is no other real DX around, at least not with me, so I think 10m propagation is poorer than on Wednesday.

Yesterday 4X1RF was spotting CN8LI at a distance of 3860km on 6m - a very good distance, probably multi-hop Es or even F2.

I may QSY to 6m later to pick up any Es around on that band. In previous years I've managed CN8LI on 6m with an ERP of around 1W..

10m long-path to Australia? Not here!

After monitoring 10m WSPR last evening/night for long-path propagation to Australia, I drew a blank. After the 10m band died to the USA mid-evening, only Europeans by Es and GDX copied here. No ZLs and no VKs copied. Others with better antennas may have been luckier. 4X1RF was spotting me at 0658z.

With a sunspot count of 162 and 20-30MHz forecast to be "normal" propagation today is anyone's guess!

14 May 2014

Will 10m open long-path to Australia tonight?

I am carefully checking 10m WSPR this evening to see if the long-path to Australia (over the Pacific) opens, especially seeing how the band has been open to the USA and Canada for hours now.  My WSPR is running overnight, but if the band is to be open long-path I suspect it will be very soon. As I write this it is 2207z.

 UPDATE 2217z:   All quiet on 10m with my last USA spot at 2126z, nearly an hour ago. Being a band of surprises, anything can happen!

Optical article in June RadCom

June's RSGB RadCom carries my article, "Over the Horizon at 481THz" describing my non line-of-sight optical experiments last year. My poor health (stroke) has prevented me doing more with this in 2014. The article was written last year (2013) before my stroke.  Hopefully, a return to good health (by the autumn?) will allow me to continue this fascinating part of our hobby. At the moment I am just too clumsy.

Testing the optical RX
8.5km "over the horizon" NLOS by clear air scattering (in a cloudless night sky) was very straightforward with simple, low-cost optical gear that could be made for next to nothing.  Unlike microwaves, optical kit is very inexpensive and requires only very basic (audio frequency) test gear to set up. Optical alignment is critical and more stable tripods would have helped. 

What amazed me was that nothing was visible or audible at the RX yet the signal decoded and displayed perfectly with Spectran software on the PC.

If you get this magazine, I hope you enjoy the article.  Please let me have any feedback.

Malawi - 7QNL

See http://www.malawihf.org/
http://www.malawihf.org/wp-content/uploads/2014/05/Zomba-Plateau-300x148.jpg
A DXpedition to Malawi is planned for late May/early June. Frequencies are shown on the website above. This is a DXpedition combined with a holiday, so don't expect "high intensity" activity. The callsign is very odd - 7QNL. Malawi prefix is usually 7Q7.

CW, RTTY and SSB activity is planned from 80m - 6m.

10m - USA/Canadian DX

During this afternoon on 10m I have been spotted, and spotted myself, by several different stateside stations (3 and 4 call areas in the USA) with best DX 6505km so far.  Interestingly, I have spotted just one South American station PY2RN (9550km) around 1200z and later.  It is interesting to see such an opening to the USA as we approach summer conditions.

There must be a reasonably good chance of long path propagation to the Pacific Islands, New Zealand and Australia later this evening on 10m.

UPDATE 1720z:   Only European stations by Es on 10m in the last few hours.

UPDATE 1725z:     VE3PLE just spotted. First Canadian for a while on 10m.

UPDATE 1935z:    TI3/AB4AW (8752km) spotted twice in Central America (Costa Rica).

UPDATE 1955z:     In among all the DX, G7FYO copied at 162km with -4Hz Doppler, suggesting aircraft reflection.

UPDATE 2010z:    DX from the USA still very much in evidence on 10m. K3NAL spotted at -16dB S/N.

UPDATE 2126z:   K3NAL just spotted (again).

70cm contest results


Stations worked on 70cm from home with 5W/5el
Last evening I took part in the 70cm UKAC contest for the first 90 minutes, by which time my voice was well past it because of my stroke, so I stopped operating.

I was using 5W (FT817ND) to the little (lowish) 5 el yagi on the pole on the back of the bungalow at home (hand rotated). Conditions appeared flat with no lifts apparent.

Best DX was G8XVJ/P in the Peak District at 181km but I missed out on M0GHZ in IO81 square (he got part of my callsign but then lost me!) at 195km.  I was pleased to work M0CES/P in JO03AE (rare square) at 103km.

All QSOs were SSB.  I did hear PA and DL.  In all it was good fun. A pity my voice was so poor.

10m - early start today

Sunspot count is 138 and 20-30MHz conditions are forecast to be "good" today. 4X1RF was spotting me regularly from 0554z this morning (14 times so far to 1114z) and I even spotted OZ7IT as early as 02204z!  It certainly promises to be a good day on 10m. Let us see.

13 May 2014

10m WSPR - no more DX seen (yet!)

Since mid-afternoon 10m seems to have fallen back and the DX (such as it was) has disappeared. 4X1RF and DK6UG have spotted me but no more South Americans, Central Americans or North Americans. Being 10m, everything can change in a few minutes!  If it does, you will find out here - I intend to remain WSPRing on 10m into the early evening, at least and whilst on 70cms.

UPDATE 1900z:  CX2ABP just spotted again, so 10m is still open to South America.

Critical Communications World (was TETRA World Congress) - Singapore May 20-22nd

Next week, 175 speakers will be in Singapore for Critical Communications World.

In my day, this was called the TETRA World Congress and it was a real chance for users to meet manufacturers and for manufacturers to showcase new products coming to market. These days I am rather out of touch and have little idea what is new in TETRA. Things don't seem to have developed dramatically since I stopped work 6 years ago.

70cm UKAC contest this evening

From 1900-2130z (from 8pm UK clock time) the 70cm UKAC contest is running.

Although I am not a great contest person, these are usually good sessions with plenty of activity, mostly SSB. It will be a good opportunity to try the little 5 element beam to see what I can work from home using it. Conditions should be close to "normal" which will be ideal.

So far I have only heard the PI7CIS 70cm beacon - no other stations or beacons. I missed the recent UHF contest at the weekend.  I was struggling with my voice in the 2m session last Tuesday, so may not stay on too long.  Let's hope I manage to work some reasonable distances.

10m quiet today - so far

10m WSPR is very quiet currently, with just 4X1RF (3519km) and 4X1DA (3597km) spotting me so far today. No South Americans  so far, even though the sunspot count is 164 and 20-30MHz propagation is forecast to be "good".  The band may well open up later to the Americas. It would be nice to see the 10m long path to Australia open up later (~20000km) as it did a few days ago. That was a total surprise.

UPDATE 1455z: Just  been spotted by EB3EPR (1248km) on 10pm WSPR. No great DX - another station probably via Es.

UPDATE 1500z: Just spotted WP4JT (6849km) in Puerto Rico in the Caribbean. He claims to be using 10mW and I gave him -12dB S/N report which is remarkable . I suspect this power level is an error and his actual power is much higher. Otherwise I'd expect to see many more stations from that general direction.  At 1536z he spotted my 2W at -6dB S/N.

UPDATE 1520z :  CX2ABP (11127km) was spotted, by me, nearly an hour ago. I missed that one. Classic 10m N-S propagation.

Things are warming up!

Lack of youngsters in the hobby and the growing RF engineer shortage

See  http://www.southgatearc.org/news/2014/may/where_are_the_under_25s.htm#.U3Ey1rGZiSo
for an interesting piece about the lack of young people in our hobby.

The original article appeared in Essex Ham.

See also http://youtu.be/6UFP158SJbY .

Having given talks to several East Anglian radio clubs I can agree this is a serious issue.  Most in amateur radio in the UK are in the older generation. It is right these people should be enjoying our hobby, but youth and youngsters are essential for its healthy future. We need to find new ways to bring them in and keep them interested.

Years ago, an amateur radio "ticket" was the only passport to a means of talking around the world. Today, with smart phones and the internet, talking world-wide no longer holds the same fascination for young people as it once did. To me, radio is still magic, but this is not the case for most young people.

Also note how many radio magazines there are on shop shelves compared with those about computers. We are in danger of facing a future without RF engineers in the UK. This is even more serious than the lack of youngsters in our hobby. The two are very much linked: if we want future RF engineers we need to grow young, keen, radio amateurs - the future is ours to influence! I never did understand why radio seems to be (mainly) a male interest.  Odd.

mcHF transceiver

Graham G8NWC has brought this QRP transceiver (the mcHF) to my attention.

See http://www.m0nka.co.uk/ .  It is described as a small and inexpensive homebrew HF transceiver.  Features (as listed on Chris M0NKA's website):
  • Standalone and compact embedded transceiver
  • Operates on USB, LSB, AM and CW
  • Large 2.8 inch color LCD
  • Four encoders and 17 buttons for easier operation
  • Fast and fully electronic RX/TX switching
  • Two USB ports – for PC control and external keyboard
  • Two temperature compensated oscillators/clocks makes it ideal for digital modes
  • Four digital filters – 1.8kHz, 2.6kHz, 3.6kHz and 10kHz
  • Built in Iambic Keyer that supports Mode A and Mode B
  • Large 48kHz spectrum display

Ten-Tec and Alpha Amplifiers merge (RF Concepts)

Apparently Alpha Amplifiers and Ten-Tec have merged creating a multi-million-dollar company with products that span QRP transceivers to full-legal-limit amplifiers.

Alpha Amplifiers has been building amplifiers since the early 1970s. Alpha Amplifiers are considered "the finest line of linear amplifiers in the world" (their words). Ten-Tec started in 1968 and mainly design and make transceivers. Both are world famous.

Sounds to me like the merger was needed to keep both companies afloat? Of course I may be totally wrong and both companies may be financially secure.

But, times are hard for manufacturers in the amateur radio world. This will become even more critical when the Chinese start really addressing the amateur market. Up to now, the Chinese have been "playing around in the wings".

QRP rigs

See http://www.vanyi.net/homemade/homebrew-hf-ssb-transceivers/ .

This page has a nice collection of links to a range of (mainly) homebrew QRP transceivers for various bands. Well worth a visit and good browse.

Amateur balloons

This is a branch of amateur radio with a very dedicated following. Amateurs launch small balloons with lightweight payloads which are tracked with telemetry on the 70cm band.  Some fall back to earth quickly, whereas others manage to cover vast distances.  Some payloads include small cameras.

See the Southgate News Page and
http://www.kf4l.org/pigs/qrp_radio_and_balloon_held_hosta.html  and
