K2 Build Begins


Inventory completed, I’ve cracked on and made a start on the Control board which is the first of the three PCB boards that have to be completed. 

So far so good with no initial problems, I’m using some thinner solder wire than previous builds and it definitely makes a difference, I only wish I’d done this for the OHR100. 


I’ve managed to install all the capacitors, resistors, diodes and begun work installing the transistors. Hopefully by tomorrow I should have the Control board completed.


I've managed to take over the conservatory at the back of the house which is a small well lit room  and ideal for building purposes as it's out the way and I can leave everything in place knowing it wont be disturbed. With the radio turned up I am left to my own devices and can happily solder away!

K2 Arrives

Finally I have my hands on the K2 kit!
It’s taken a long time but at last the kit arrived in this morning’s post. I’ve already had a quick peek and begun the inventory checks. There's a lot to check but everything is so neatly placed in the box it’s almost a shame to unpack it. I love how each individual packet is labelled with a note of who packed it, it’s a real nice touch.
 Not so neat now as I've had a good rummage.

Hopefully I’ll have the inventory done by the end of this week and then I can begin the build. I will adhere to my usual rules, those being to take it slow and steady and check everything as I go along, normally I’m happy doing two hour slots but we will see how it goes. 
 The manual is huge, more like a novel!

I’ll try to take some pictures as I go along, but there are plenty of websites around who describe the build in detail so I won’t be doing a specific build sheet. 
 The start of the inventory check, each bag is unpacked placed in a separate box and ticked off
I’ve also been in touch with Elecraft and ordered the 100 watt PA and the audio filter, (the UK distributor only had the basic kit). 
Obviously more to follow as I progress.

Kent Paddle Key


Some good news at last, my Kent key kit arrived and after a fairly simple build is now connected up to the FT 1000MP V. 


The only snag having rarely used a paddle was which way round I should connect the dashes and dots. After watching a few demonstrations on the web I quickly sorted it out, though not before attempting to practice with the dots on the right paddle and the dahs on the left! (I wondered why it didn’t feel right)!

First impressions on tapping away are pretty good, I thought I would really struggle but it actually seems to come reasonably naturally, obviously I’m fairly slow at the moment but speed will come with practice.


I have to admit it's a beautifully crafted piece of kit and looks great sitting in front of the rig. It's quite chunky and  has a good weight so it doesn't slide around even with my clumsy attempts, I'm very pleased with it.

Almost forgot to add the K2 is coming next week
Long story short, the UK Elecraft dealer suddenly has a K2 in stock and by chance when ringing them to inquire about another product they happened to mentioned it. Strange indeed, but hell,I bought it there and then in case I was dreaming and the kit should arrive next week, happy days!

K2 Blues

Well once again my bad luck with overseas purchases has struck. 

At the end of last week I rang the UK Elecraft dealer trying to find out if there was any progress and suffice to say there was no change in my order and consequently no sign of my K2 arriving. 

From what I could gather the kit had not even been ordered and it seems they are much more interested in the K3 KX3 or KX1 orders and certainly don’t stock the K2 kits here in the UK. I'm not even sure if they've ever ordered a K2 for a customer, (I got the impression they didn't like the fact that someone might complain if they made a hash of building it).

Thoroughly disappointed I cancelled the order as I could see that I just wasn’t getting anywhere. The price of the pound against the dollar has recently taken a hit and is not brilliant at the moment so ordering direct from Elecraft is a possibility but may prove costly; I guess I’m going to have to wait. 

The only other option is to see if any come up on Ebay but of course I lose the fun of building the kit, the ideal situation would be something like a partly built kit but I doubt that will happen. 

So unfortunately I just have to accept that I'm going to have to wait a little longer for my K2.
To cheer me up I ordered the Kent twin paddle key kit which should be arriving in the next day or two, hopefully concentrating on the build and learning to use a paddle will take my mind off the K2!
................C'est la vie!

Time For a Switch


Many may be surprised that as an ardent CW fan (I rarely speak on the radio) I’ve never used a paddle key, having stuck with a straight key for nearly 16 years. Actually I tell a lie, I have, but a long time ago when I was first licensed and really it was too early and I was put off by the experience. 

Now that I am tapping away on a daily basis my Morse has moved on and I can quite happily converse at 20 wpm, the trouble is my sending hovers around 18 wpm max and if I try to speed up with a straight key mistakes naturally happen and it get uncomfortable after a few qso's. I could persevere and stretch myself (and sometimes I do), but quite honestly I should have used a paddle some time ago.

I love straight keys having 5 different keys ranging from a very nice “Stillwell”, a Himound, an old Watson and a couple of Czech keys these being the two I use most of the time. But as I said you find yourself limited and I think now the time has come to move to paddles. 

I’ve been watching Ebay to see what’s about and spot any bargains but so far with little luck. I want to start with something fairly moderate like a Kent and see how I get on. Hopefully with time and practice I will switch over fairly easily but it won’t happen overnight, so I must remember to be patient and put in loads of practice. 

Once I’ve bought the paddle I will post up some pictures, any advice on switching from straight to paddle will be greatly received!

K2 Ordering Issues

When ordering kits and bits from overseas my luck always seems to run out. The OHR 100A took nearly 4 weeks to arrive, evidently it had got lost in the vast empty space of the UK postal and customs service!

Two weeks have passed since I ordered the K2 and still no sign, so I was getting slightly agitated. I emailed the UK Elecraft distributor to enquire of any news, the reply was not good, quote: "Elecraft are out of stock of the K2 at this moment".

Now not that I'm suspicious but I know as do most potential Elecraft Kit owners if I go on to the Elecraft website there is a page all about stock levels, naturally if we have just ordered our new kits we like to see that all things are in order before we pay out are hard earned cash. So on reading the mail from the UK distributor I went to double check, because I distinctly remember when I ordered my K2 I checked the Elecraft website for stock.

Well, someone is telling porky pies because the Elecraft site clearly states K2s are in stock. Hmm, some peeps may call me a pessimistic old git, but my initial feelings is that my order was either mislaid or forgotten, (perhaps I'm wrong), but what's the betting that in approximately two weeks from the date of this post I receive my K2?

K2 The Wait Continues


Coming up to the 2nd week from ordering the K2 so I’m hoping it should arrive in the next few days, although I wouldn’t be surprised if it takes another week. Sometimes customs are pretty good and things go through quickly and sometimes it can take forever. 

Meantime I’ve been playing with the OHR100-A and getting some pretty good QSOs all over Europe, it really is a great little rig, the receiver is very sensitive and picks up weak signals just as well as my FT1000MP V but of course I have all the filters for the FT and so can narrow everything down. With the OHR100 you’re a little limited but providing the QRM isn’t too bad and using the bandwidth you can have some fun with just 5 watts.

I’ve taken the two meter yagi down, I just wasn’t using it and I could put the rotator to much better use with something like a Hex or another Moxon. Two meters is fairly quiet round here and to be honest I rarely chat on the bands, looking in the log my last conversation on the radio was over two years ago! With the Yagi and the 50MHz inverted V both sitting doing nothing I might just advertise with the local club just to see if anyone wants them or maybe just dismantle them both.


 Re another antenna we’ll see what I can come up with once I’ve done a bit more research. I am limited in what size I can use, having a cobweb, a 30m vertical and an inverted V all up in the garden does clog things up and a great big Hex or Moxon might not go down too well!

K2 Ordered

The money has been handed over and the K2 order is in, now it's the wait .......possibly a whole 2 weeks! 

To think it was only back in June last year that I started my QRP quest with the little old Rockmites then the OHR100 A,  now I'm ordering the kit I've always wanted. I've feel I've come a long way since June 2012 and am quite ready for the challenge, in fact I'm really looking forward to it. 

All the Elecraft reviews I've read point towards how good the kits are and the great support the company provides. Fingers crossed I wont need too much support but it's nice to know its there should I need it.

In the next few days I'm going to join the K2 build forums and have a good read, naturally once the kit has arrived I will publish how I get on, so obviously watch this space.

60 meter Band Big Disappointment


I’d built my 60 meter antenna and had hung it up in the silver birch at the end of the garden, all connected up ready to start listening full of anticipation. 

Over the past week I have listened and heard the odd ham but quite honestly I was disappointed, I was hoping for more, no CW at all, nothing all week. As for side band there were a few but enough to count on one hand. 

Then this morning as there was a big competition going on and most of the bands were busy I’d thought I try 5MHz to see what was about, 5.325.00 to be precise. What I heard really astounded me and believe me I’m no saint, the language was colourful to say the least, whoever these two muppets were they were local boys from around Gloucestershire, it wasn’t hard to tell by their extremely thick Gloster accents. 

No call signs naturally, just happy to gossip about various people in their neighbourhood whom obviously they didn’t like and in doing so swear as much as they could. As I said I’m no saint but you don’t swear on the radio, certainly not the language they were using its common sense, something that these idiots were obviously lacking. 

In the end after listening for about 10 minutes in case they gave anything away I gave up and turned the rig off. I’m taking the antenna down, I don’t want to be a part of that, its part of the reason I hardly do side band, give me CW any day. No doubt there will be operators out there saying if you don’t use the band you will lose it, well sorry I won’t be a part of that particular band when there are idiots like that around. Enough said and back I go to CW! 

On a different note I’m almost ready to buy the K2, I rang the UK distributor and at the moment they are waiting for new stock, so I will ring back next week and put my order in. I must admit I was tempted by the Kenwood TS 590 but after serious investigations (mainly through Eham and You Tube) I decided on the K2. Overall the impression is that the RX quality of the K2 is marginally better but of course the winner for me was that you have the pleasure of building the transceiver. 

I’m going for the basic 15 watts first and see how it goes, I’m really looking forward to building this rig, after all it’s taken 3 RockMites and one OHR 100A to get to this point. More updates will follow once I have the kit.

W3DZZ Trap Service and 5MHZ Dipole


Since I’ve serviced the G3TPW Cobweb and completed the G3TXQ, I decided I might as well check the traps on the W3DZZ antenna and re-tune if necessary. Also I’ve successfully applied for the 5Mhz so I need to make up an antenna for that band. 

The W3DZZ has been up for a number of years and is a really good antenna for 40 and 80 meters. The 40m was originally set for the CW portion of the band and 80m set to 3.700MHz for some listening and the odd rag chew. 

The antenna was made from instructions I found off the web, a piece written by GM0ONX. I was that impressed I actually contacted him to say what a great antenna it was and how easy to build. He very kindly replied and informed me that it was literally built in a day and by chance he managed to get it published in Practical Wireless!




My particular W3DZZ uses the coax traps which were very easy to build and seem to work really well. GM0ONX's design is very easy to follow and simple to construct and if you're starting out this is an excellent way to get in to trap antennas.




You will require an antenna analyzer to tune up the traps



Recently I've noticed that the SWR has been reading quite high and I've been repeatedly having to tune up. So it was definitely time for a service; I removed both traps and did a quick check with the MFJ 259, the SWR was showing 1:1 at around 6.800MHz and it also looked like the coax on the tubing had slipped slightly and just needed some re-adjusting. 

It was just a matter of removing the electrical tape and adjusting the coax, then gently trimming the 40 meter portion until I got a good reading of 1:1 at 7.0030MHz, I also lengthened the 80 meter portion by 6" each end to drop the peak to around the CW part of the band. Once both bands were set with the correct trim it was just a case of re-taping the coax traps up and making sure everything was waterproof.

 Multi coloured trap (adds a bit of colour to the garden)!

Now SWR readings are good at 1:0 for 7.030 and 1:1 for 3.0550, it's funny how once all connected back up you'd swear the receive signals sound much better!

The 60 meters antenna will be an inverted Vee and I’m using the 1:1 ugly balun I made some weeks ago, (see previous posts), I’ve roughly trimmed it up and once I have it raised up in the silver birch at the end of the garden will do the final trim with the MFJ 259b.

The 5MHZ dipole complete with 1:1 ugly balun ready to be mounted in the silver birch tree, the red tag reminds me which is the positive end!


Having the MFJ 259b for measuring my home brew antennas does make building a lot easier. Another accessory you can buy (for some stupid sum of money) is the loop coupler for measuring traps and coils, my Brother in law has one which I borrowed when I first built the W3DZZ. 


 However, as he was away this week I realised I’d be stuck for doing the trap measuring. There was no way I was going to buy one , so I decided to have ago at making it, after all it couldn't be too difficult.


 Thankfully I had a 100 watt soldering gun and all it took was some reasonably thick copper wire and a male to male 259 connector and a simple case of soldering one end of the wire to the centre pin and the other to the outside ring. I've probably made the ring a bit too big, but hey the traps fitted fine for testing so it works and cost me nothing!
