GM3OJV/P Operating Portable   February 15th, 2015

TravelPaddleI set out this month on one of my regular trips to Scotland. I have long enjoyed Scotland, so much so that about 20 years ago I bought a cottage on the edge of Loch Linhe, Fort William. If you want to experience quiet bands, then I can recommend getting away from it all in the West Coast of Scotland. The S-meter hardly moves unless there is a signal. If only that were true in the South East!

I recently purchased a camper van. 9 years old but only 28,000 miles on the clock. My little K3 soon found a place in the kitchen area and I installed a Diamond 18MHz antenna on a hatch mount. With this I had a few CW contacts using a set of internal AA cells. But I could not resist going QRO up to 10W by connecting to the v 23leisure battery.

It is too early to assess the success of this little combination, but the ability to make a cup of coffee, in a cosy environment (I have a diesel heater) with my KX3, at some of the quietest locations in the UK, certainly has its attractions. There are also significant dB gains to be had by operating from a coastal site or with a mountain close behind which acts as a reflector (G6XN style). Peter GM3OJV/P.

Yaesu FT-817ND Travel Paddle   January 30th, 2015


We will shortly have this new Watson TravePaddle-FTR which fits directly onto the side of the FT-817. Once the bracket is installed it is very easy to remove when not needed. The paddle comes reay wired to plug directly into the transceiver. The paddle has adjustments on either side to adjust the feel of the key. We have tested this key in the field and have been very impressed with it. And what if you are left handed? Well we will have a left handed version to be mown as the TravelPaddle-FTL.

The price will be £89.95 and the paddles should be available during February. So if you want one, get in touch with our sales department.

KX3 Beefed Up!   January 14th, 2015

KX3 Beefed uo
I recently took the opportunity of grabbing some samples that had come into the office. They looked interesting, particularly as they were for the Elcraft KX3 and I own one!

The first item you will see is a replacement heat sink that makes the transceiver run cooler. I personally have never noticed it getting that warm, but I guess if I was operating data, AM or FM, then I might appreciate it more. But it looks great.

The second item was a pair of side cheeks that include “handles’ whose primary function must be to protect the tuning controls and other knobs. Again it looks great.

From the photo you can see what a difference in appearance these items make. We will be selling them shortly I am sure. Peter G3OJV

Compact CW Paddle Key   January 2nd, 2015

Screen Shot 2015-01-02 at 16.55.32

The market is pretty crowded when it comes to CW paddle keys and the price range is equally extensive. For most, the requirement is for a key that is mechanically sound, works and feels good, and does not cost the “earth.’

So with this in mind we have been looking to bring to market, something that comes as close as possible to this requirement. Our newly developed key is pictured above and is quite compact but quite heavy, with a rubberised base that seems to grip the desk surface very well indeed. One interesting feature is the cable connection. This is a achieved by means of a 3.5mm stereo socket on the key itself. As most radios use this connection, a simple 3.5mm to 3.5mm lead is all that is required to connect the key to the radio.

Preliminary tests look promising and subject to further testing, this key should be available in a few weeks. Peter G3OJV.

2015 Arrives!   January 1st, 2015

Screen Shot 2015-01-01 at 11.20.46

Well, 2015 has arrived and a very Happy New Year to all those who are reading this blog. We all made it to the year 2015! I guess that there are thousands of greetings going back and forth ver the air waves today, and for the next few days. So as we head into a new year,, from the ham radio perspective, I am sure there will be some new exciting developments, new products and new ideas. All this is very good news for us hobbyists.

One of the comments i receive regularly, both in the shop and on the telephone, is problems with lack of space for antennas and problems in making contacts compared with the achievements of other stations. And I always try and first of all to find out if there is indeed a technical problem. Usually there is no technical problem, but simply the owner of the station just cannot compete with the “big guns” who have high powered amplifiers and big antenna systems. I am sure we have all felt disadvantaged at times. For some it is lack of space, for others it is a lack of cash, and for many it is both! Buth there is an answer.

Those who can identify with this problem and feel disappointed need to sit down and think over their situation and perhaps their attitude to the problem, or indeed the hobby.

Ham radio was originally an experimental hobby, and still is to many. Experimenting means a challenge and it is here that those who feel depressed with their results, need to change their attitude to the rut that they may feel they are in. A small garden and low power can work, but not as well as a 1KW station with a tower and beams. So stop comparing yourself with these stations. Instead, focus on what you have and treat what you regard as a disadvantage into a positive challenge. Let me give you an example of something I read about recently.

Michael J Rainey, AA1TJ, is a USA ham operator who is a great experimenter and had been working on a heterodyne single device VFO in order to produce a simple circuit that would generate a 14MHz signal. That in itself was a challenge. He didn’t need to use just a few components. He could have achieved the same with more components which would have made his task easier. But he didn’t!

He achieved his goal and then added an amplifier. I should add that although this took place in 2013, he was using very early solid state devices dating back to the 1960s. The result was a CW transmitter that produced 2mW. That’s right 2mW! His curiosity carried on and he decided to see if he could make a contact. He eventually got a response from a station over 900 miles away. That station was running 5W to an Elecraft K2 and coming in to Michael’s 2-stage regenerative receiver at S8. He got a report of 439 running just 2mW and the QSO lasted for 7 minutes.

So here is a simple question for you to ponder over on New Year’s Day. How does that achievement compare with a station runnung 1kW on 20m and working 12,000 miles into VK/ZL? Think about it! Peter G3OJV.

Antenna Matters   December 29th, 2014

Screen Shot 2014-12-29 at 22.02.24

I recently nad a need to bring an HF antenna lead in through a window opening. Not the most popular thing to do in the winter months! Even RG58 did not allow the window to fully close and resulted in a considerable draft.

One of the items we stock is a mobile coax lead designed to feed through the hatch back edge closing point and this involves the use of a very thin mini cable that is quite robust. On one end is a plug and the other end a socket. This makes an effective way of bringing in a coax feed whilst allowing the window to be fully closed.

Buddipole Buddistick for Mobile.

The buddipole range of products is well know around the world and I have used them for a number of years. My favourite is the Buddistick as it is so versatile. And it always struck me that it could be used for mobile operation. It is one of the more efficient antennas because of its large coil and lengthy resonator whip which is very easy to adjust.

Most mobile installations use an SO239 socket mount on hatch or boot mounts. The buddipole system uses a 3/8″ stud mount. This can be resolved by the use of one of our 3/8″ to PL259 adaptors. This makes a very simple and effective HF mobile installation. Peter G3OJV

Diamond Compact HF Antennas   December 25th, 2014

Screen Shot 2014-12-25 at 21.02.17

I have always favoured single band mobile antennas over multi band types because of the lower losses and the fact that they tend to be easier to tune. Multiband mobile whips can give rise to spurious resonances because of additional self resonances over and above those that are intended.

Diamond of Japan are perhaps better known for their VHF and UHF range, but the compact HF single handers carrying the suffix “FX” such as HF20FX for 20m, are worth a serious look. I am using these myself at the moment.

The first advantage is that they are fitted with a PL259 connection, so they easily plug into the popular hatch and boot mount connectors. Secondly, they have an easily adjustable resonator whip that does not require the use of any special Allen key.

These are base loaded designs on a small former which gives them a slightly wider VSWR bandwidth than would otherwise be obtainable. They also easily unscrew into two sections making them easy to stow away. And finally the Japanese engineering shows through.

If you are thinking of going mobile, look them up on our web site. Peter G3OJV

It’s Not All Ham Radio   December 25th, 2014


I spend most of my working days talking about, writing and selling ham radio. I also spend some time operating. But sometimes you need a break and need to switch off.

Sitting in front of a TV has never been my idea of relaxation. However, I do very much enjoy music and this has always been an important part of my “other” life.

The picture above shows part of my music studio where I compose and mix. This involves writing some backing tracks for local singers. My great love is jazz and I do about one live recording a month for a local group of professionals. From these tracks we extract the best and then I spend several evenings editing and mixing.

It’s miles away from the ham radio hobby, but it keeps me busy and stops me dropping off in front of the TV!

RSGB Christmas Contest   December 24th, 2014

Screen Shot 2014-12-24 at 21.47.54

Christmas Eve is upon us and another year is drawing to an end. Boxing Day heralds the beginning of the RSGB Christmas holiday contest covering 6m 4m 2m and 70cms. This is run from 1400 – 1600 on the four days from 26th December to 29th December.

I did participate in the contest last year in order to test out my 2m LFA Yagi and found it quite a pleasant way of fitting in some ham radio operation without interfering too much with the family Christmas. In fact that two hour daily period is often the time when everybody is recovering from their midday meal!

Having just returned from a Christmas Eve carol service, and settled down with a glass of wine, it really seems like Christmas. This year I may try some fixed operation from my mobile setup, to see how far I can get. As with my participation last year, I will not have a competitive station – far from it! But it is a chance to quickly test the station’s ability on the VHF/UHF bands and at the same time, avoid falling asleep after a meal at Christmas.

A Happy Christmas to you all. Peter G3OJV.
