Alternatives to QRM

Every year about this time, I make a station upgrade. An amp three years ago, a tower/Yagi two years ago and some ergonomic upgrades last year. The DX season is approaching and I want to make the best of it. This year’s upgrade was slated to be the K3 innard that’s been on my mind…

G3XBM (Roger)


I have been a member of the Radio Society of Great Britain (RSGB) for 52 years now. When I first joined I was an SWL associate member - A3554 - as a young teenager.   In those days you had to be proposed and seconded. Joining is much easier today.  When I started there was just one licence. I took my RAE exam in 1966. It was on Friday 13th May as I recall.  I attended RAE classes at Plymouth Tech every Monday night, catching the bus to Plymouth after school. Long gone days!

Over the years I have not always agreed with the RSGB's decisions. In fact, quite recently, I did not like the decision worked up with OFCOM to allocate the 146-147MHz band to some UK amateurs by NoV.  I think the RSGB could have got a much better deal for UK amateurs, but that is my personal view.

Despite this, the RSGB is our national society and deserves our support. Over the years they have supported UK amateurs very well and have a much better relationship with OFCOM than the ARRL has with the FCC in the USA where bands we have had access to for years are still not available! The monthly RadCom magazine is a good read with a mix of technical and non-technical articles.

So, if you are not an RSGB member and you live in the UK, may I encourage you to join?

10m WSPR unique spots today so far

So far today, 24 unique spots of my 10m WSPR-AXE 500mW "all in one" beacon, mostly from the USA and Canada. The little beacon has not been re-synchronized to internet time for several days.
Unique 10m WSPR spots received so far today of the 500mW beacon
UPDATE 1910z:   The last USA station to spot me tonight was WG2Z (5600km) at 1742z.

Stroke update

I had my cerebellum brain bleed (stroke) in Sept 2013 and in all honesty I was expecting to be fully fit again by now. I think my wife and I had no idea how serious this was and just how long recovery was going to take. Nearly 15 months on it is a mixed picture.

All my limbs, my eyes and ears and my cognitive functions seem to work OK. But I still have poor liquid swallow, poor speech, giddiness when walking and I tire on the least physical exertion such as washing dishes or gardening. My stamina is better than it was but it is still far from right.

I am still clumsy and amateur radio construction is still out of the question, which I find very hard to accept. This, and my speaking problem, is why I currently use WSPR so much.

I am told a full recovery is probable, but this will take time. This last year as been very hard. I sincerely hope 2015 will be a better year.

In summary, I have felt old suddenly. Until last year I felt as if I would last forever. Now I feel far more vulnerable.

Skeeter Hunt Certificates

The first 3/4ths of the 2014 Skeeter Hunt certificates went out in the mail last night.  I ran out of 9X12 envelopes and will get more. The remaining ten or so will go out Thursday night, as our Tech License exam session is tonight and our monthly South Plainfield Amateur Radio Club meeting is tomorrow night.

If you earned a certificate, it has been noted on the Scoreboard spreadsheet, in the "Notes" column:

Thanks for your patience, and I apologize profusely for the delay - but hey, like John Lennon said, "Life is what happens when you're busy making other plans."

Look for the Skeeter Hunt to be making an appearance on Facebook in the near future! Oh ..... and there will be at least one change in the rules for next year. Look for that announcement in the Spring of 2015. (Hey, I gotta give you something to look forward to!)

BTW, I want to take an opportunity to mention something about the "QRP - When you care to send the very least!" and the "Skeeter Hunt" items that I offer through Cafe Press.  There's no big markup there - each item is offered at $1 above Cafe Press cost. The proceeds (which ain't much - believe me!) go towards the purchase of ink, paper, envelopes and postage for the Skeeter Hunt certificates. Next year, I am hoping to offer plaques to the top three finishers.

DL-SWL on 472kHz

Overnight DL-SWL (701km) spotted me no less than 7 times on 472kHz. I was using my short baseline earth-electrode "antenna" with a maximum 5mW ERP. Not my best DX but very pleasing. With no real antenna, no loading coils, ANYONE could join the fun on 472kHz!

Sunspots - Friday Nov 21st 2014

Sunspot number today is 83, almost the same as yesterday, but 10m daytime propagation is again expected to remain "good".

So far, no exotic DX with the little 500mW WSPR-AXE 10m beacon with best spot so far from 4X1RF (3519km) plus LZ1OI and UR/SWL56.  No Australians spotting me, well yet anyway.

Guinness record for most QSOs meets birthday celebration?

In early 2000, Juka OH2BR was recognized by Guinness Records for making the most QSO’s ever in a single year from a single location. He was operating as VP6BR on Pitcairn Island and accomplished that record of 56,239 QSO’s in only 3 months. Mark ON4WW is hoping to beat that record in 2016 by operating…

As regular readers of this blog will know, I just love WSPR. It amazes me that such weak signals can be detected so well at such great distances using this mode. I am even more impressed that such a simple "stand alone" (no PC needed) beacon can be constructed.  My very simple, TINY little 10m W5OLF WSPR-AXE beacon has been copied all over the world now. It is truly TINY.

Landing on a comet

One cannot help but be impressed by the space probe Rosetta to a comet and the subsequent landing of the Philae probe on the comet's surface.

This week I learned that one our friends was the Project Manager for this at Astrium back in the late 1990s. He is now retired but he was invited back for the landing. I hope they manage to get the lander moved to a better illuminated spot.

I was very impressed.

Arizona on 10m

Best 10m DX today,well so far, with the little 500mW WSPR-AXE beacon was WA7HL (8508km).  There is still a chance that I might get spotted in South America later, but somehow I doubt it.

El log online se ha activado en el Club Log y el primer conjunto de QSOs se han subido. No te preocupes si tus últimos QSOs no aparecen inmediatamente, debido a la conexión de Internet poco fiable, los logs han de ser enviado en un ferry cada día de Neil Island a Port Blair y, a veces puede llevar un día o dos para ser subido. Por favor repite contacto sólo si crees que tu Qso fue malo.

Gracias a Club Log y Michael G7VJR por el gran apoyo como siempre.

Teng en cuenta este correo electrónico para consultas del log - vamos a ver esos mensajes de correo electrónico sólo después de la expedición una vez que haya finalizado y el equipo haya vuelto a casa.

Triple Play Special Event Day

As all Amateur Radio operators know, you never know what you're going to get on any given day. It might be a rag chew, or a DXpedition, a quick contest QSO or any number of other possibilities. As I headed out to the Jeep for my lunchtime QRP session, I didn't think I'd end up with three "Special Event" type of contacts.

The first was on 10 Meters - PW2BA. This was actually more of a DXpedtion type of QSO. A team of Brazilian operators have gone to this small island, which is IOTA SA-024, and which also has a lighthouse on it - ARLHS BRA-013.

Their signal was up and down with wild QSB. One moment they were 599, and 559 the next.  I was wondering if I should even try, using QRP. Throwing caution to the wind, I did and got an immediate response!

From 10 Meters, I wandered over to 12 Meters, where I worked W1AW/5 in Arkansas.  Not sure whether or not it was one of W1AW/XX stations that I already have in the log, I decided to engage the pileup (which was pretty big!). It took a bit of listening to figure out their listening pattern, but I finally did and busted through.

A quick tune through 15 Meters seemed to indicate a dead band.  I tuned from 21.000 MHz to 21.060 MHz, up and down about four times. Hearing no signs of life, I headed on down to 17 Meters.  There I heard W70.  I had no idea what it was, other than since it's a 1X1 call sign - that means Special Event station.  There wasn't a huge pileup and the operator was actually operating simplex.  I had to wait my turn for a bit. There were many stations calling, and I noticed the operator was trending towards working stations that were sending at a reasonable code speed.  The speed demons were being ignored, so it seemed. So I tweaked my code speed down a touch and threw out my call - success!

Coming back inside, I fired up the computer and QRZ'ed (new word!) W7O, and discovered that the Special Event station was commemorating the 40th anniversary of the launch of AMSAT OSCAR 7. Being a child of the Space Race, I was quite pleased to have worked them and will send out one of my brandy-new QSL cards, which I received yesterday from KB3IFH. Their QSL card (shown above) is a very classy design IMHO, one I will be proud to display.

Sunspot number has dropped back to 72 today. 10m propagation is forecast to be "good".  The 10m band has been open to the USA yet again this afternoon, but no great DX seen on the band for my little 500mW WSPR-AXE beacon today.

10m WSPR analysis by Bert PA1B

Bert PA1B has analysed my 500mW WSPR spots today, ignoring the many spots by local G4IKZ.   It shows the signal strengths (uV/m) implied by the S/N figures.  In many cases, much lower powers would have been enough to get "spotted".  Thank you Bert.  Of course, for some people, the noise floor limits the minimum signal that can be detected.
UPDATE 2200z:  The last USA spot of my 500mW was WG2Z (5600km) at 1724z. Just local G4IKZ (18km) since then.  Now QRT on 10m until after breakfast, but will stay on 472kHz overnight.
