New FT-991 At A SPECIAL PRICE?   August 30th, 2014

Screen Shot 2014-08-30 at 21.47.33

Yaesu displayed their new FT-991 this month in Tokyo. There are no firm dates for arrival in the UK or indication of price. It covers 160m to 70cms. There is no mention of 4m. If they have not included 4m, they have seriously missed a marketing trick.

The price could be sub £1000.

Key Log go

I can’t really remember the last time I tried RTTY. It was probably when I was trying out data modes a good few years ago. But I have just been trying out our new accessory for the Elecraft series of radios. It is known as the Key Log Go. In effect it is a very comprehensive electronic keyed with 20 memories and display facilities that also offers PSK31 and RTTTY. The latter is achieved by plugging in a keyboard that also permits the sending of CW.

What I really liked was the fact that I can now display up to 4 lines of text on its screen. This makes data operation much easier. Any PC keyboard with the right connection will work just fine I managed a few RTTY contacts without any problem and without a PC. PSK31 was just aseasy. Power can be from an internal PP3 battery or an eternal 12V supply. With the internal PP3 and the internal AA cells in the KX3, I am totally portable and what is more, the LCD screen is just fine in the daylight, which is more than can be said for a PC.

Bicycle Mobile with KX3   July 31st, 2014

Cycle Antenna

The picture above shows my latest set up for bicycle mobile. I hasten to add that I do not operate on the move as I don’t think it is practical or indeed safe. I use an Elecraft KX3 transceiver powered by AA cells. That way I operate in the lightest possible way and use the Elecraft dedicated paddle key. My bike is a Tern Link7 that folds up really small, yet is very rugged. That way I can easily put it in the boot of even a small car.

For the antenna I have chosen the Buddistick with their clamp p[tion arrangement to attach it to my cycle carrier. The complete antenna set up can be purchased as the Buddistick Deluxe kit. I run a short earth wire from the bike frame to the base of the antenna feed socket on the Buddistick clamp. The whole antenna system together with the KX3, easily fit into my pannier bag which in turn easily detaches from the bike. For more information on the bike, check Evans Cycles on the web.

There are a number of considerations to observe when using the setup. The most important is the earth counterpoise. I try to keep everything simple and compact. A separate earth counterpoise does the job but is a bit of a nuisance in laying it out, particularly in public places. Setting up the resonance, even with the counterpose, can be unstable. The whole system VSWR can vary depending on whether you are touching the transceiver case or not. At first I failed to resolve this issue, but some thought and some tests resolved the problem.

Firstly try and find the best tappings for each band on the Buddistick. You can fine tune with the whip and then make a note of the settings. The coil taps can be fixed so it is only the whip length that needs to be recorded. Do all this without an antenna tuner. This is very important. On the KX3 you can programme one of the short cut keys to bypass the internal ATU for you. Now once this is done you really do need that antenna tuner to stabilise the VSWR and make the system less “touchy.” I love the internal ATU for the KX3 as this is just amazing in the way that it matches in a fraction of a second, even wide impedance ranges.

The bike metalwork does not provide enough earth for bands below 21MHz. I found that the easy and most effective way is to simply use a fairly long feeder to the transceiver which also acts as a counterpoise. Mine is about 15ft long. A choke formed by a few turns of coax on a ferrite former at the transceiver end will make things even more stable.

The beauty of the system is that it is very simple, very efficient and very compact. It is possible to consider using a radial stretched above the ground as a resonant counterpoise, but it does mean a little more work in setting up. I prefer to use just the bike frame and the coax feeder. The KX3 has super low battery consumption. If you really wanted to raise the power you could use an external 12v supply and run up to 12W. The KX3 still works at battery levels down to 8V so there is no sudden death. The radio also has very comprehensive system monitoring so you can watch the battery volts very easily.

Give it a try.

Ten Miles and Three Watts   July 22nd, 2014

I spent another day in the Peak District of Derbyshire, with my bike and my Elecraft portable set up. It was hot, very hot. I used my Alex Loop as the antenna. Conditions were not great, but that does not detract from the fun.

P1010763

I have been based in Wirksworth and decided to cycle to Duffield, a route which allowed me to take a look at some old railways stations. The road distance is just over ten miles.

P1010717 I stopped at Idridgehay station, long since vacated by British Rail. But interestingly, the line is now in private ownership and has been brought back to life. In the summer months there are 4 return trips a day between Wirksworth and Duffield. This suited me fine because it enabled me to continue by bike to Duffield and then get a lift on one of the rerun train trips to Wirksworth. They kindly let me put my bike in the luggage area which saved me having to fold the bike. A great day out.Peter G3OJV.

An Uphill Struggle   July 21st, 2014

I am in the Peak District and it is very aptly named! Having ridden around some portable sites and clocked up 10 miles, I appreciate how flat, by contrast, Essex is.

The weather is fine and conditions on the HF bands are good. But oh, those steep hills. I suppose if I was to be operating on VHF, I might feel a little different about the Peaks! Peter G3OJV

QRP with No Outside Antenna   July 20th, 2014

photo
I have come up to Derbyshire for a few days and my usual travel companion is the Elecraft KX3 coupled to the Alex loop. This time I erected it indoors and my first QSO was on 15m with DM5EE.

It is not the first time that I have used the loop indoors but it does prove that even if you cannot erect an outside antenna, and even if you run QRP, it is possible to enjoy ham radio.

I also have ny fold up bike with me, so if the weather is kind, I wmll try some portable operation.

World’s First KX3 4m QSO   July 16th, 2014

KX3-4m-Close

The world’s first 4m QSO using the Elecraft internal transverter for the KX3, took place today at 11.30am UK local time. This took place between G0PEP (operated by Peter Waters, G3OJV) and Ron G8FJG. The KX3 was running 3W output on SSB and Ron was running 40W to an FT-847. At both ends the antenna was an InnovAntennas dual band 6/4m Yagi.

The reason that the QSO took place in the UK was because 4m is not available in the USA. So Elecraft asked us to make the first on air test of a pre-production unit. This went without a hitch and the transmitted SSB signal was reported as being excellent. It is estimated that production units for 2m and 4m will be available as from September and we are now taking firm orders – no deposit necessary.

If you would like to see the video of the first QSO, then check out YouTube. The link will be placed HERE.

The Truth – Nothing But

One of my tasks is to check our competitors’ adverts and web sites and to see if there are any issues arising. It amazes me that some of the things I read are so far from the truth that you just hope that readers do not believe some of these outrageous statements,

Today I had a phone call from a potential customer who pointed to a very well known web site and read it to me. He could not believe what he was reading. He was right!

In all areas of commercial business there is always the odd person who wants to go one step further, no matter how it is achieved. The tragedy of this, is that it is at the expense of the customer, who may at the time not appreciate that he is being lied to. And one can only wonder at what is said over the phone or in the shop.

Ham radio is a very tight community and there are no large companies in the market – although some like to think that they are in that category! Companies are generally run by one individual who controls most of what goes into adverts or on the internet. To see this happening in a hobby market by so called fellow enthusiasts is a worrying aspect.

Most customers can spot the outrageous, but just how many more subtle lies are being used to promote sales?

For those who have often wished for a UK price that was like the prices enjoyed by our US cousins, here’s some really good news. The Flexadio 6300 model sells in the USA for $2499. The US customer would normally have to pay on top of this price a sales tax typically around 8%.

Now look at the UK price including 20% VAT, of £1695. The fact is that there is virtually no difference in the price. And if a UK customer tried to buy from the US, there would be a massive freight charge to be added, plus clearance PLUS 20% VAT.

So at the moment, the Flex-6300 is a great deal. Better get yours today before things change!
