Today I celebrated my birthday and reflecting on the past year I realised just how much I have achieved during my first year as a bona fide radio amateur.

While I gained the foundation licence back in September 2013 it was only at the start of the year that I took possession of my first proper radio and began my first real forays into the hobby. That is not to say the end of 2013 weren’t without its highlights, remember ICube-1?

While the foundation level licence gave me access to most bands, be it at only 10W, I was not content to stay as M6GTG. I passed the intermediate in May (2E0NRD) and finally got the full licence in October (M0NRD) and have slowly been honing my operating skills.

I competed for the first time in the RSGB UKAC and other VHF/UHF contests. They have proved to be an enjoyable and educational activity. The structure exchange helped me overcome my initial microphone shyness and the goal of improving my score each week to become more competitive forced me to improve my set up.

Construction of a headset interface and the addition of a foot switch were simple projects as was the building of a simple but effective Moxon antenna for 6m (blog post). This together with a permanent antenna pole, rotator system and upgraded coax all have helped me improve and learn. I even tried my hand at some portable operating with varying degrees of success. I have received some invaluable help and advice from people, especially Robert G1ZJP (M1MHZ) The results for the year have been coming in and I am very happy with my final positions in the various bands for a first timer and hope to be more competitive next year. .

HF operating proved initially off putting, plagued by QRN/QRM and my initial microphone shyness I veered toward the more noise immune data modes. I built a data mode interface and have had a fair degree of success with PSK/JT65 and RTTY as dabbling with a few other modes and over the last few weeks I have experimented with FreeDV and find it fascinating.

As I have become more confident I now operate voice more often and now regularly give points away on contest weekends because I like the short formalised exchange. Indulging in small talk in normal contacts is something I am not good or comfortable with but as I’ve got to know local operators I have started to join in the local nets and art of conversation is becoming easier.

The High Altitude Ballooning (HAB) has taken a back seat at present. I still have active plans to get a flight up with my own payload and have given a number of successful talks to local clubs over the year which I have enjoyed. Missing the UKHAS conference was a bitter disappointment but I still track flights and I hope to reinvigorate this interest in the spring as I get back up to speed with recent developments. 

Due to time constraints I have also mothballed plans for numerous construction projects based around the Arduino. Last months rearrangement of the shack should allow me to finally get around to finishing them.

Operating the JOTA station GB2FFC for a local scout group was very rewarding. The write up from this blog was included in the latest RSGB Radcom magazine and we hope to do it again next year. Being asked to contribute content to the AmateurRadio.com website came as a surprise and thanks to all those who have commented on my ramblings.

Another rite of passage was managing to repair my first rig, an elderly TR9500, yes it was only a modest achievement but a massively satisfying one and it has given me some confidence in purchasing second hand equipment in the future.

As well as building up the shack and continuing to improve my setup and operating I have some specific aims for next year...

Make a proper satellite contact
Satellite reception and tracking is something else that has been neglected recently, though I am still decoding FUNCube-1 telemetry daily.

Make a meteor scatter contact
I attended a fascinating presentation at the Spalding and District ARS by Robert G1ZJP about Meteor Scatter operating just before the Perseid meteor shower. I have made a couple of attempts since including during the recent Geminid shower and while I can receive signals no problem I have yet to make a successful contact. It is definitely on the to-do list but I may need to increase the power output, maybe even investing in some amplifiers and better antennas who knows it could lead to attempting some EME!

Make a proper SOTA/IOTA activation
Next year I will be holidaying in Scotland on the Isles of Skye and Islay so want to make a better attempt at operating in these more remote operating than I did this year. I also want to take a radio up a mountain!

Become more involved locally
I joined the South Kesteven ARS last year and regularly communicate with members of the nearby Grantham ARC. There have been suggestions of operating special event stations as well as repeating the JOTA event. I enjoy the meetings and conversations and is nice to bounce ideas off each other and hope to be more involved in organising activities.

Anyway, still a few hours of my birthday left so off to enjoy a wee dram or two and a slice of my birthday cake made by loving XYL

Back in September I attempted to repair a Kenwood/Trio TR9500 UHF All-modes transceiver for a fellow club member. It had a faulty microphone pre-amp which I replaced and all seemed well but it had further issues with the receiver. Cutting his losses and wanting shot the owner sold it to me for the princely sum of £10.

I have had her back on the bench and initially couldn't find anything wrong. However in real use it become apparent that she was in fact profoundly deaf! Picking up test transmissions from the nearby FT857D or Baofeng outputting into a dummy load was one thing but it wasn't receiving anything else!

From the service manual and schematic I deduced that it could be the initial RF receive amplifier. It is a dual-gate mosfet (3SK76) It proved tricky but I managed to source a replacement on eBay and it was a simple job to replace once I'd extricated the PCB.

I can report it is now working and the video below shows it monitoring the GB3EE repeater in Chesterfield. From the coverage map I shouldn't be able to hear it but I can and reception has been marginal at best using other receivers but it repaired TR9500 doesn't have any problems.


I wonder if the rig has been subjected to a high RF field in the past this could easily have damaged the receiver amplifier and an induced RF into the microphone lead could have damaged the microphone pre-amp. It just seemed strange it having both faults.

Tuesday night is the last 432MHz UKAC contest and hope to use her in anger.

After working the QRP Fox Hunt last night, and over time working a bunch of DX and a lot of the W1AW Centennial WAS stations, and other pile up causing stations - I really have to wonder what goes on in the minds of some people.  It seems like when there's some kind of quarry to be had, whether it be a QRP Fox, a DX station, or a W1AW/XX station - common sense goes right out the window and sheer insanity takes its place.

Take for instance last night.  I was trying to work Steve WX2S on 40 Meters who lives about 18 miles from me.  Ground wave was strong enough that he was about a 229/339.  The advantage was that not only could I hear him, but I could also hear the stations that were calling him.  I ended up not working him, but even so, it was a unique opportunity to observe.

Steve was working split from the beginning and he was handling the pile up deftly.  But I was left shaking my head, because so many times - all through the hunt, people continued throwing out their calls while Steve was engaging another station! I sat there, kind of dumbfounded. There was Steve, sending out "559 NJ STEVE 5W" to whomever, and all the while there were stations sending out their calls, over and over and over, without so much as taking a breath!

So here's the deal......if you can't hear the quarry well enough to realize he answered someone other than yourself - then why the heck do you continue to throw your call sign out there in the first place? Obviously, if by some miracle, he actually came back to you - would you be able to hear that well enough to realize it and complete the exchange? Something tells me ........no.

Part of pile up discipline (on the part of the chasers) is to realize when you have a legitimate shot. But in any case, whether the quarry is 229 or 599 on your end, don't you think it would be a lot wiser to send your call maybe twice at most and then take a break to actually listen?

Listening. That seems to be a dirty word in the minds of a lot of folks.

Look, I know we all make mistakes and I've made my fair share, too.  No one is perfect, and I can understand forgetting to turn the "split" function on or some other such thing.  But deliberately sending your call over and over and over in the vain hope of somehow scatter-gunning the target is really just inexcusable, and rude and inconsiderate of your fellow Hams.

As always, this is just my humble opinion. Your mileage may vary.

QRP - When you care to send the very least!

It's December, and that means Christmas and Hanukkah are right around the corner. And sometimes for a Ham, "The Holidays" presents a quandary.  Imagine this scenario - your lovely XYL comes over to you and asks, "What would you like for Christmas, Dear?"

You look lovingly into her eyes and say, "A 60 foot Rohn tower with a 3 element beam". And then you get THAT look - and you know instantly, in your heart of hearts, that your request has gone over like the proverbial lead balloon.

Or maybe the wife of your best Ham bud calls you and asks, "What can I get Jim for Hanukkah this year? And no, I'm not getting him a 60 foot tower and a 3 element beam".  What do you say? Somehow, I don't think K3, or IC-7800 or FT-DX5000 would go over too well, either.

So, as we get closer to the gift giving season, I'll post some items that I come across that may help break the "What do I get for my favorite Ham?" log jam.  My aim will be to keep to suggest gifts that won't break the gift giving budget while at the same time would be a gift that almost ANY Ham would enjoy receiving.

I came across this one this morning on Facebook (see- Facebook is actually good for something!). I thought this was unique, and I sure wouldn't mind having one of these hanging from my shack wall.


This is a little plaque commemorating the 50th anniversary of the ARRL postage stamp. It was issued by the United States government for two reasons - to celebrate the 50th anniversary of the ARRL, and in gratitude of all the valiant work performed by Hams during the Alaskan earthquake ans tsunami that occurred that year.

You can get this little beauty from Hamcrazy.com.  It's reasonably priced and will not break the bank.

Suppose you are a CW aficionado, or perhaps your Ham bud is.  The following is always a perennial favorite - the Morse Express Christmas Key.


The above photo is the key being offered for 2014.  These keys are small enough to be used as a Christmas Tree ornament, but yet are fully functional. One of my most favorite straight keys of all times is the 2004 Christmas Key which my lovely Marianne gave me that year. It has a fantastic feel to it and is perfect as a traveling portable QRP ops straight key.

Please note that I am in no way connected with any of the companies offering these fine wares. I receive no recompense and I have not even been asked to endorse any of these items. This is just W2LJ offering a public service to those of you out there who may be stymied by either of these two  questions - "What can I give?" or "What would you like?".

To be continued as I come across neat stuff!

QRP - When you care to send the very least!

This weekend I have managed to get the FreeDV program working successfully and made a couple of QSOs on HF.

FreeDV has received a fair degree of publicity recently and is a GUI application for Windows, Linux and MacOS (other platforms are in development) that allows any single side band radio to be used for low bit rate digital voice communication.

I was primarily interested in it for possible use on VHF. It is hoped that the recently introduced 146-147MHz allocation available in the UK to full licence holders (via a Notice of Variation) will be used for digital mode experimentation. I have been constructing a data mode interface for use on the old TR9000 since it can operate on these frequencies but I decided to try the FT857D on HF to get an understanding of the program.


With FreeDV speech is compressed down to 1600 bit/s then modulated onto a 1.25 kHz wide 16QPSK signal which is sent to the mic input of a SSB radio. On receive, the signal is received by the SSB radio, then demodulated and decoded by FreeDV. The appeal being communications should be readable down to 2 dB S/N, and long-distance contacts should be possible using QRP power.

There is a lot of information. videos and guides available on the FreeDV website but the basics are straightforward. The computer requires two sound cards to handle the audio to and from the radio and the speaker/headphones and microphone. One method is to use a USB 'gamer' headset but since I already had a spare PC headset with 3.5mm plugs I opted for a cheap plug in USB soundcard (as detailed below)


Once the audio devices and PTT control are installed and configured within FreeDV it is a matter of monitoring a frequency (in USB) and hopefully you can send and receive.

So far I have only managed two QSOs with Trygve (LA6UOA) and Fabrice (F4FPG) on 14.236MHz with both the audio was clearly understandable but did suffer from the odd breakup and stutter. This was probably due to the laptop being used rather than an issue with the signal as the FreeDV needs a reasonably powerful machine with a decent amount of memory.

The software is very picky, several times the audio device settings have been forgotten or it has come up with a cryptic error message:

../src/msw/bitmap.cpp(846):assert "image.IsOk()" failed in
CreateFromImage(): invalid image

This is a known issue with the Windows version and the solution is to manually remove all of the FreeDV settings from the registry. The full details of how to edit the registry are in the GOTCHA section of the FreeDV site. Editing the registry is not recommended to the inexperienced person so is not a great solution and when starting the program backup after this fix requires reconfiguration of callsign, sound card and PTT settings again.

Despite this setback it is an excellent and exciting new mode. Both Trygve (LA6UOA) and myself were first timers when we had our QSO and we were like excited school children once we were able to converse successfully. Fabrice (F4FPG) was an old hand at it and I thank him for allowing me to briefly interrupt a QSO he was having with another UK operator who I could not hear.

I would recommend using K7VE's QSO Finder website http://qso.k7ve.org/ to see who is monitoring and on what frequency as well as passing hints in real time.
