RSGB issuing 'G' callsigns..

A candidate who had just passed his Advanced exam has discovered that the Ofcom licensing website will issue old, unused amateur radio callsigns, in his case a G6.

Paul 2E0EAN tried selecting various permutations of Advanced (Full) call from the Ofcom website as he recalled reading somewhere that they were running out of M0's and would start using up the gaps in the system. After several tries the system offered him the distinctive G6FAX which he immediately took.

The G6 call block was originally issued in the early 1980's. It is not known which other callsigns blocks are available from the Ofcom system but half of the G2 call sign block was never issued so may be available as well.



Very interesting, so is this a good or bad thing ?

CW, QRS.

Yes, it's coming on slowly, very.

I have downloaded a program that uses the Koch method, whereby you start by learning two letters at a speed of 12 WPM or greater, once you have gained an accuracy of  >90% over a 5 minute copy, you can add another letter, and so on.

So that's M and K sorted out then !

Nothing much else to blog at the moment, the bands have been very quiet this way, don't know how everyone else has been finding it ?

Czech Army key.

Whilst I wait for the shiny iambic key to make it's way across the Atlantic, a search on the internet found this website - http://www.czechmorsekeys.co.uk/.


The key was made in the early 1950's for the Czech armed forces, and I have to say, though this is as a complete novice, it feels like a very nice key, quite solid with a pleasant action.


A pal of mine, Ken, G3SDW has one, and he highly recommended this key to me, who am I to argue with someone who has been using CW since well...let's just say a long time !


The price of these keys are 20GBP including UK postage, I think that it a real bargain, I can only assume whoever is selling these has bought quite a job lot !



The key on my desk, note the CQ crib sheet !


Close up of the key.



Note the lettering, I think this translates as 'receive' as there is an arrow pointing upwards !

I'm surprised no one has asked..

what is that picture all about, at the top ?

Johnny Depp and Alan Wyatt with their Advanced RCF exam pass sheets.

Perhaps I decided that rather than being outed on Twitter, it was better to save my money and come clean, yes my other love is AMATEUR RADIO...there I feel better now.

Enjoy the cartoon, you've probably seen it before, still makes me chuckle.

Finding the incentive.

Even though a fellow blogger friend of mine recently said that the secret to working the rare DX for the <100 w station was morse code, I, and I suspect most of us (and especially the die-hard phone users like myself) begrudgingly already know this.

Radio wise I have been stuck in a little bit of a rut recently, stuck on 91 DXCC, with 49 confirmed on eQSL, so I'm one off being able to print the next certificate off, I have been busy though, sending QSL cards off, however radio activity has been mostly working special event stations and any stations of interest, like when I worked F/HB9LCP, Sandro, on holiday 100 Km from Bordeaux, on the N. Atlantic coast, great QRZ.com page showing his camper vans.


Anyway back on subject, a pal of mine has recently taken up the code, and is slowly and surely catching me up DXCC wise, well I cant have that, so what better incentive is there to learning than by actually having your own morse key, so this is on it's way from the US of A.


It's an Iambic paddle from Vibroflex, I saw it and fell in love with it..

Seeing that on my desk will be the incentive learn the code.
Or become an expensive and shiny doorstop.

New blog on the block..

I've not blogged for a couple of weeks, I suppose there hasn't been much happening for me on the radio, however one of my radio friends on the facebook has started blogging, I think she could definitely be worth following..

Further tests to the homebrew 2m band Moxon Rectangle..

It turns out that I do have an SWR meter suitable in a Zetagi meter that I bought for HF, I checked the specs, and it's good for up to 200 Mhz !

In the shack I use a colinear antenna for 2m, this is up in the loft, the shack being in the front upstairs box room, so I tuned around to find activity on the Plymouth 2m repeater, around 30 miles away, signals were coming in around an S5.

I plugged in the moxon and could receive the same signals around an S7, turning the antenna made a noticeable difference, as did turning it horizontal, it was fun making the signal come and go at will, having only ever used dipoles and verticals.

Upon checking the SWR, I got the following readings -

144000 - 1.6
145000 - 1.5
146000 - 1.9

This was with the antenna hanging vertically from the top of the shack door !

I did some extra checks and have concluded that the antenna has a bandwidth for a 2.0:1 SWR of about 5Mhz !

Homebrew 2m Moxon.

Thoughts have turned (no pun intended) to directional antenna's, having looked at the Yagi and Quad antenna designs, I then stumbled across the Moxon Rectangle, this 2 element antenna offers similar gain figures to a 3 element Yagi, with better F/B ratio's.

I am quite active on the 2m band, but mostly on FM, you know chatting with your radio club pals etc, however in the vehicle I have the Icom 706, which has 2m SSB, I have made a few calls, but with little success, knowing that most use horizontal polarisation, myself using a dual band Watson 2m/70cm vertical.

For the Moxon I used two  3/4" 'tee' piece's and some scrap plastic pipe, along with some bare wire found at work, an SO239 socket and some cable ties, the most useful item ever.

Following dimensions found in the internet (link at the bottom) with use of a hacksaw, side cutters and tape measure, knocked it up in about 1/2 an hour.

I am unable to check the SWR properly, as I don't possess a VHF meter, and for some reason the 706's meter shows 1.2 even with no antenna connected, I did try it with an old cb twin meter, swr meter, checking on the cars vertical first for a 'sanity check' reading, against that it showed an SWR of around 2.5:1, so some adjustment required.

Initial test's showed it has directional properties, it opened a repeater 11 miles away, then did not when I turned the antenna around, I also found a continuous signal around 145.000 which I could alter the level of signal with the moxon, managed to find the direction and the signal was also better with the antenna in the horizontal.

The signal was an S9+ 10dB on Moxon horizontal, in the vertical position it was S9 with little noise, the Watson 5/8 vertical was then tried, S9 again, but slightly noisier.

Further tests to follow..


Typical radiation pattern.

10m FM..

My blog posting is a bit like buses, nothing for a while, then two at once, yesterdays opening on 6m was too good not to blog, and then the day got even better..

I use the Kenwood TS-480, as shown on my blog page, this radio has some up/down buttons for changing bands, so starting on top band, you can click up the bands, when you get to 10m mine then shows 28500 USB, then 29600 FM, then 6m, 50150 USB.

As mentioned there was a lift on 6m, and being a big fan of 10m, you can imagine these up/down arrows get a lot of use, so earlier I flicked from 10m USB and normally on the 10m FM portion hear nothing, well not today, for booming in at 5/9+ on 29600.0 was WP3UX.

I was fairly sure this was a station from Puerto Rico, as I've worked there before on 10m SSB, mindful of the way FM propagates I didn't want to waste time, but still I needed to be sure, so a flurry of fingers on the keyboard (well two actually) on QRZ.com confirmed my suspicions.

A few calls was all it took to receive a 5/9 report back, though the QSB was pretty bad, next came EC8ADS in the Canary Isl's.

Finally, and this took some working, as he had quite a pile-up, was PY2WC, from Sao Paulo, he was at times 5/9 +30dB, though again subject to heavy fading.

This is my farthest FM contact at 5735m, it took me back to a time when as a cb'er I worked into New York on the local FM calling channel.

10-4 !

First 6m opening of the year.

I have a routine when I get in the shack, main pc on the internet, load up qrz.com, dx sherlock and the dx cluster pages, switch on the radio then load up HRD on the laptop for the cat control.

Have a listen around the bands whilst checking the cluster, I use the cluster primarily as a tool for propagation, (as often by the time good dx has been spotted, the pile up has started), and so this morning at around 1130z, it was nice to see lots of spots for 6m.

What may of helped was that there was a contest on, so managed to work some inter 'g' along with a new square IO81, thanks to G4JFK/p, however the band started to open to the south, with two new squares, IM87 and IM86, with EA7RZ being my best and farthest south DX at 944 miles.


I have found that the ZS6BKW to be around 4-5 's' points up from the Sirio 827 I used for 6m last year, the 827 being resonant for 10/12m, though it tunes for 6m, the ZS6 offers in excess of 6 dBd gain, with a multi lobe pattern, so looking forward to some fun on the 'magic band' this year.

Much on telly tonight ?

I have been trying some television broadcast today, well actually slow scan television on 15m, as that band has been open across the Atlantic most afternoons.

Here is the result of the only contact I managed, using the SSTV program that comes with DM780, which is part of Ham Radio Deluxe, this software is used also to control the CAT functions on the radio.


The first picture is a cheesy one of the Good lady, with myself trying to smile..


VE3RNG first transmission back to me.


I had the auto slant options enabled, but didn't quite sync properly, you can just see in the bottom left my transmission that he received.

This is by far my farthest SSTV transmission at 3650 miles, using 85 watts, into the ZS6BKW.

More than one way to skin a rabbit..

Or bag a new DXCC, one of the many that I have never heard, but have wanted to work.

I am talking about Paraguay, now Brazil and Argentina I hear quite a lot, especially now that 10m is opening up, also Chile and Venezuela, Paraguay however I have never heard, so when I chanced upon ZP5DBC at 5/7 with QSB on 10, well it has to be worth a shout.

After a few calls and getting nowhere, I heard my pal, G0VQY get through on his second call, I was even more determined to get through, I wont however shout and shout, instead timing single and full calls when he called QRZ, still no luck though.

Sometimes you just now it's not going to happen, so I decided that maybe the data modes would offer an opportunity, so down to 28120 and PSK31, I think it was fate as the cursor on the waterfall was exactly on the trace of ZP8AE, he was a little outside the AF passband at 2700 Hz, so I adjusted the vfo up 1 Khz to bring him in at 1700 Hz.

Of course it wasn't easy, it took 5 calls, with him calling back other stations, and finally I saw him call M0PCZ !

Two new DXCC close to home.

Last night was Radio Club night, and what better way to start the evening than by working some new DXCC on 2m.

I heard a station on 145.500 FM, G0VHS, Terry in Weymouth, Dorset which is about 45 miles from my qth, this got me thinking, is there a lift on, anyway before I had a chance to call back, my local pal, Alan, G2DXU has done so, and I follow up to listen.

As soon as I heard Mike, GU3WHN, from Guernsey (distance 84 miles) break in I knew we were onto something, so Alan brought me in and we worked them both, with reports of 5/3 both ways.

As we said 73 to go off to the club I heard Ian, GJ7DNJ from Jersey, (distance 106 miles) so I decided to call him from the mobile, so I switched the amp on which gives 100 watts out, and gave him a call, and was delighted to receive a 5/9 +60dB report !

From our club location, I switched the amp off and wound the power down to a watt. and still received a 5/3 report, I suspect we had some very nice tropo ducting !

Remote radio operation.

I have dabbled with using my station remotely, using a remote desktop application, this allows you to control the 'base' or shack computer, as my TS-480 is connected to a laptop and can be used fully via Ham Radio Deluxe.


Sound duties are taken care of by using the existing hardware set-up used for data modes, the software used is Skype, freely available, and free to use between skype to skype accounts, one set up on each laptop, base and remote.


This does work, though I find that the connection is quite laggy, and the desktop image shown is not the clearest, also the audio on receive can be somewhat choppy at times.

Earlier this week I had a long and interesting qso with NZ5E, Terry, in Arkansas, he is using the same radio as me, but remotely, we talked a lot about a beach buggy he and his son have restored, it wasn't until after we said 73, that I realised that I hadn't asked him exactly how he was running his remote station.


Well today I happened across two local friends of mine on the air, G0VQY, Penn, in Brixham, and my radio club pal, G2DXU, Alan, in Torquay, they had been working some Stateside on 17m, and so I joined them, well by chance Terry, NZ5E returned Penn's CQ, and I was fortunate to get to ask Terry exactly what he was using to remotely control his station.



He was using the Microbit RRC-1258 system.

No computer connection is required, I think the next picture explains..



I am hoping as there is no 'video' connection, only audio and radio command that the bandwidth demand on the internet connection will less.

Also my thoughts are you could then use your home station when truly on the move, for example in the car ?!

HRD LOG.net

I have always used Ham Radio Deluxe - http://www.ham-radio-deluxe.com/HRDv5.aspx to control the TS-480 , along with DM780 for the data modes, and finally the integrated log book, which also allows you to automatically upload to eQSL.cc and finally to HRDlog.net.


Here http://www.hrdlog.net/Default2.aspx you can view your log, edit any incorrect entries you may have made in HRD logbook, you can also do the usual things, search for callsigns, view DXCC worked etc, but more interestingly perhaps, you can view a qso map in google maps.


Just click on 'qso map' from there you will see 'open with google maps', this brings up another page, which is in Italian, if you don't 'parlare italiano', then you can have the page translated.

Facebook HAM friends.

Unless you have been living in a cave for the last few years, you will have undoubtedly have heard of Facebook, well I'm not going to and start a debate on it's pros and cons, however I will say that is works for me personally.

For example I have a friend Adriano, IZ3SVI, from Venice, Italy who likes to work portable of a weekend, so he'll put a post up on an Amateur Radio page advertising his event, then assuming there is enough signal for his phone, post updates as to what frequency he is working.

However today he had no signal up on Pizzock Mountain, but luckily I managed to find him on 20m, not easy when he is in qso with his pal in Venice, and I barely speak tourist Italian !

As we have only become friends through Facebook and have never actually spoken to each other, it was a real pleasure to finally be able to, Ady was a 5/7 though faded badly with the qsb, and finally recovered back to a 5/3 or so, with the 100 watts and vertical fishing pole antenna !

Here is a pic of Adriano, doing what he loves best !


And here is my facebook page link - go on poke me !

Many hands make light work..

Yes, so they may, but when it comes to radio, 'many ears make light work...of the DX'.

This week I have been off work, but instead of lying in I have been up around 0800 and on the radio, and with the help of fellow club Ham, M0PAW, Keith, who also lives in Torquay, we have been working together to work the DX, and I would like to say, we haven't done too bad.

Using 145.5375 FM as a contact frequency, we scanned the bands, 40m and 20m, and also using the DX cluster, would tell each other of any good dx, and so far this week have bagged the following.

I worked -
31/1/11 - 08:14 VK7GK, Gerry, in Tasmania on 40m.
03/02/11 - 08.10 ZL4IV, Rex on South island, New Zealand, on 40m.

With Keith and I working together -

03/02/11 - 09:10 PY6RT, Rob in Brazil on 20m
03/02/11 - 09:40 C5YK, Andre, in The Gambia, on 20m.
 and today.. VK2GHK, Henk, just north of Sydney, also on 20m.

All the contacts were SSB with 100 watts into the ZS6BKW, with Keith using a rotatable dipole by Comet.

I have now worked VK on 2 bands with a bit of wire, which due to the high winds here last night now has a thick telephone cable resting on it, will call British Telecom later to report.

Lastly, Henk (VK2GHK) has a website whereby if you have worked him, you can print out your QSL card, and here it is !

Monday 31 January 2011

VK7GK worked on 40m.

Worked Gerry, VK7GK on 7134 LSB around 0900 GMT this morning, with solid 5/5 signals both ways !

I have never even heard VK on 40m, let alone worked, and yes this was my first VK contact since becoming an Amateur, Gerry was using 300 watts into a 2 element quad, with myself using the ZS6BKW and 100 watts.

Propogation is such a fickle thing, I was trying to work a contest station over the weekend on 40m in Romania, he was a 5/5, could I work him, no chance, and he was calling back UK stations, then I work Gerry after just one call, and we spoke for around 10 mins, good signals with very little fading.

G4ILO Echolink node.

I expect that most of my blog followers also follow the blog of Julian, G4ILOhttp://blog.g4ilo.com/ - However publicity usually is always good, so when I read about Julian getting his application for an echolink node approved, I thought I would see if I could access his node via my iPod with the echolink app I downloaded.


At first it said the node was busy, so I left it, I tried again later, even though it was still saying busy, anyway it connected and Julian answered !


Julian's audio was very good, with no distortion, I have to admit that I am an 'RF man', however it was good fun and has now encouraged me to try the echolink on the iphone a little more often, as I don't have a radio on me all the time !


G4ILO-L is EchoLink node number 3098.

License to ragchew..

Since I have put up the ZS6BKW antenna I have found that I am actually putting out a half decent signal on 40 and 80m, so the types of QSO have been changing, now instead of the 5/9 73, I am spending perhaps 30 mins talking to just one station, and you know what I love it !

It's not doing my DXCC score a lot of good though !

Still the odd foray onto 17m for the DX though, I cant help myself.

Having said that, 17m is a relaxed band, and I am finding that the improved antenna and the ability to use some more RF is helping me to make some longer trans-atlantic contacts.

HAM life is good.

G2DXU - A brief history.

When I joined the Watcombe Amateur Radio Club around 1 year ago my basic intention was to take all three exams required to gain the full license, here in the UK, this means you would then receive an M0xxx callsign.


Another new member also joined around the same time as myself looking to take the exams, his name is Alan, our backgrounds are very different, but it mattered not as having the same goal and interests meant that we helped and encouraged each other, so we went from SWL to full callsigns in under 10 months.


Alan had a relative, a silent key, Robert lever, who sadly passed away in 2007, Bob had served in the RAF during WW2. Bob’s callsign was G2DXU. The G2DXU had originally been issued as 2DXU, an Artificial Aerial Licence, sometime between 1920 and 1939. In 1946 these licences were re-issued as Full Licences with the G prefix. 


Alan spoke with Robert's wife and she kindly agreed to let Alan use the G2 call, all Alan had to do then was pass all three exams and apply to the RSGB, which he did, and now the paperwork has come through, he is the proud owner of G2DXU !


As the G2xxx call pre-dates the 2nd World War, it certainly is a rare callsign, I have only ever heard one other G2 on the air.


Good luck to you Al with the G2, that is one pile-up generating call if I ever heard one..

West Coast surfin' USA with NB7PX..

Been a bit poorly the last few days with the old 'man flu' bug that's doing the rounds, anyway managed to get some cover at work and slipped away home early today and straight to bed.

Woke up a few hours later, around 1500 GMT and span around 20m only to hear a couple of West Coast, Stateside stations ragchewing, I have not managed to work this area, and it's not for the want of trying.

Whenever I am in the shack I have 3 pages on the PC screen, QRZ.com, DX Cluster and DX sherlock, which gives propogation path maps for each band, so I had a look on the cluster to see what DX is about and noticed a DX net on 14244 with NB7PX, Jerry, in Oregan, this caught my eye as these nets I have found to be the easiest way to work some DX.

He was calling for stations, only the last two letters, it took two calls and 'Charlie Zulu' was on the list !

Jerry gave me two reports over the hour I was on, initially a 5/8 and then a 5/6 as the band was starting to close.

Thanks a lot to Jerry, I feel a lot better now, nothing like a bit 'surfing USA' to banish the winter bugs !

ZS6BKW is this the multiband answer ?

Firstly I would like to wish everyone a Happy New Year for 2011 !

This afternoon I felt the need for some air, so what better thing to do than get out in the garden and do some antennas', I like to experiment and build my own antenna's, I have been using a homebrew fan dipole with some good success, I really like the idea of balanced multi-band antennas, my next project is likely to be a cobbwebb type design, anyway for now ebay brought me for Christmas a pre-built ZS6BKW antenna.

This antenna is about 91' long with 40' of 450 ohm twin feeder, which you then attach your 50 ohm coax, the design is a computer modelled variation on the G5RV, and it gives a nice matching impedance on 5 HF bands, 40,20,17,12 and 10m, mine also tunes on 15m (it shouldn't, but does work) and also the 6m band.

With some internal ATU help it tunes on 80m, I have managed a psk contact into France, and have been reported around the UK.

On 15m earlier today (the designs non-resonant band) I managed a psk contact into east coast USA, so this band appears to be a bonus, not sure why it works though !

Interestingly I put some psk calls out on 14070, and was reported all over Northern Europe, with only one report into East coast USA, on my fan dipole it was normally all USA and no Europe.

Here is a link on what I think is a little known and so far interesting antenna.
