Just a quick one really ! I’ve got an AlexLoop here, and cant wait to try it out.
I saw this excellent video from Waters and Staton
I was just wow, got to have one, but the price, eek, thats scary, but look at the performance in video i was conviinced this is the right portalable/QRP antenna for me. Ironically W&S didnt have any in stock (step in Nevada) who did, and wow, it was here quick !
The eagle eyed of you would see a number of books on my desk as I’m currently very busy with my AI&Game Design module of my MSc, i’m hoping that I will get enough time to have a play with it over the weekend. I’m super excited thats for sure !
So my last post on tidying the shack i had the radios in place where I thought I’d might like them, but of course I’ve made some changes as the tidying progresses !
I’m more than likely going to put a small adjustable shelf above the TS690S/FT659 and 2200H to allow for the other components that are used in connecting them.
I’ve got the build and electrical test desk with the require microscope and oscilloscope setup. I’ve not got any kits to build at the moment, but I’m glad ive got a decent area to build and test in now. Getting things sorted and into boxes/labelling really takes the most time, but worth it once done, and plenty of capacity. I’ve kept the left side for ‘components’ and the right storage box for ‘hardware’ like screws/tools,etc.
I’ve still got my HF boxes/shelves to go thru and sorting thru the larger container boxes, but slowly the shack is getting better in being tidier and managable. Once everything is in place I’ll be using velcro to tidy the cables up. Next is to get the audio sorted with filter/amp and speakers back in place.
Having made some progress on tidying the shack, I started to place the radios in their respective positions. One item I have had for a while, but not fitted, is the Piexx FTS-8px, so took the opputinty rather than leaving it out, to have it in ready for when connecting the antennnas back up.
The instructions are clear and easy to follow, only requiring a cross-headed screwdriver to get the case off. I had done some work already and removed the resistor which occupied the CTCSS socket.
Getting the board out took a bit of leverage with a small flat-bladed screwdriver, but came out easy enough. This was a very well put together radio with serviceability in mind.
I took a look around the board and look into the Yaeseu everything still looks really good all this years on.
One my Yagi is reconnected it will be a case of monitoring the 6m band to ‘come alive’ and see what, if any, repeaters I can hit. The nearest one i can see is in Bristol. some 46.96 nautical miles away.. we shall see, 6m has the reputation fo being the ‘magic band’ and its a case of being equipped ot make the most of it !
Having enjoyed a nice drive down to Poole Harbour after work I tuned around after a day of WSPR activity on the 7300. Results showed that the bands where pretty closed from the QTH, so I wasnt expecting alot of contacts.
I was tuning thru some of the programmed memorys in the 7300 to see if there was any activity, but it waws all quite, but then on 10m (28Mhz) a sudden group of very clear conversation, and interesting as well.
I listened in for around 30 minutes as the group discussed upcoming holidays and mobile operating along with the setups to be taken, a very interesting topic as its something I would like to do myself. It was great to hear other operators discuss band conditions as welll.
Having built up enough courage I waited for a gap to get part of my call sign in “2E0” I got out as quickly as I could as not to interrupt the flow. Thankfully on my 2nd attempt I was picked up and introduced to a friendly group of local operators, the furthest being Blandford and exceptionally clear. It was geat to hear that my setup was equally clear and we continued to discuss my Hustler setup. I was also informed of another ‘net’ on 10M lower down the bands, which I then went onto monitor, waited for an opputnity to introduce myself, and then made some contacts. Operating hear was much harder with interference and conditions making the signal barely audiable.
I did put both locations in my 7300’s memory for next Wednesday evening and it was great to have a decent QSO with local, friendly operators, furthermore it was great to see how well the hustler was doing in difficult conditions.
I will be doing further work on the 6BTV hopefully this weekend and puting the feedline underground having ordered 10ms of Extraflex bury so it can go safely underground.

Good day all ! Making this a quick one as its interspersed with Univserity Assignments and Tidying the shack !
So I have made good progress on building racking and getting things ‘generally in place’ around the shack, its still a right old mess i dont mind saying, but its getting there, and better than it ever was with the old tables.
I had some valuable input from a fellow HAM on my WebSDR that the VDSL interference was plain to see, so after a few years away from Virgin Media, I’m resuming my Internet access from Virgin, once that is in place and all my ‘essentials’ proven to work, I’ll discontinue my IP/VDSL link, hopefully that will reduce the QRM.
I did have a chance to play with the IC705 in the garden this weekend, but results on the portable antennas were slightly disappointing.
I did put on a measured radial for 40m but the nearest resonate frequence was a massive 3kHz away ! If the weather holds up, i’ll try out my buddipole, as for temporary use its worked pretty well, whats more i can configure it for VHF/UHF as well by constructing a JPole, so it might be the best antenna for the IC705 without an additonal outlay on more antennas.
I’m going to be quite busy with a couple more Univeristy Assignments and work-work, but will do my best to keep the blog going !
Its been a busy end of the week in the QTH – generally tidying up, or in the process of ! After doing a number of supporting activties, I continued to tidy the shack up !
The first task was to clear enough space for the new shelving. I used the static space where my current corner desk is to give enough clearance.
Having got a nice clear space, i then set about hoovering – there was so much dust !
As on queue, the racking arrived from Amazon – time for both me and doggo to get some exercise before building the racking !
Having enojyed a break and a nice walk in the park with Sweety, i set about builidng the first set of racks. These a shelves/racks that can go 1.8m high, i used them in a half-form factor to create two desks. Having ordered two of these, I was able to create two ‘desks’ with middle shelves, and two others with a nice bit of capacity. The build was quite straight forward and was able to complete with just a rubber mallet.
As time and the day drew on, it was time to start organizing the basic placement of where things will live, or thereabouts, freeing up the my desk and allowing me to continue working.
Having applied a number of layers of conductive tape to the top-most layer of the shelving to get started, i was able to return the radios and start placing the other items in their general locations. I was quite satisfied with the days work given the extent of how disorganized it was at the start of the day. I’m hoping I will get the cable management attached to the relevant loctions and hopefully be back on the air by Monday evening, with at least the 7300, WSPR Raspberry Pi and KiwiSDR.
So for the first time in a VERY long time (aka YEARS) I’ve had the luxury of a week off work. During the week I found a USB extender was producing a horrific amount of QRM. The offending item has since been disconnected.
I went on to survey my ‘shack’ and that I had ‘allowed’ QRM to ‘sneak’ back in. I was a bit disappointed in myself to be honest as I had spent allot of time and money on virtually eliminating interference, both man-made and natural when I had my TS690S setup as my only station. I was just not paying attention to what I was putting in the shack.
So to make up for my lack of attention, I wanted to understand why this had come about. Mostly the biggest problem is the ease to just add things in and not test them, only to find out they are ruining a hobby I really love.
Looking around the shack I really noticed how even tho I had moved much of the music equipment out, it was still as not as organised as I would like it. Did I need all these computers ? Do I use them regularly, is my setup optimal in terms of service ? For many of the computers, especially my older mac, i really no longer needed it and many smaller projects have come and past.
I looked around our whole house and many things had changed since we moved here, so maybe it was just as good to take a holistic look and think ‘how can i solve this’. With that I rented some storage space nearby.
I was really able to take a big “bite” out of all the things around the house and no longer using. I wont share the pictures on here as its not strictly radio related, but fair to say I made good use of the space and freed up alot of space around the QTH.
This in turn allowed me to think about back in the shack. How can I get desks/working areas tidy and serviceable. I’ve been using computer tables mostly that dont really have the best storage on them, leading to problems of not putting RF chokes on them and ensuring the QRM was reduced. I put too much trust in the power strip RF filter to think it would fix all my QRM issues – obviously it would not.
First call – Ferrite, lots of it and the right sort. Whilst I have VHF/UHF transceivers, allot of my work is on HF. I researched the best ‘general’ ferrite for HF, and think that FT140-43 will reduce/eliminate the RF from getting in and out of the devices. With that I ordered 40 FT140-43 from Qubits. Now *everything* that is in my shack will at least have these ferrites on the power supply/leads, if not more.
I then looked at the desks. I need them to be serviceable. The power-tray racking helped, but I was still having cable management issues, and as us radio operators know, having loops of wire here and there is a great way to introduce unwanted QRM into the shack.
I ordered these Garage Shelving Unit from Amazon which can be split to make a nice height desk and storage space, reducing the amount of ‘wire tangle’ and allowing me to have small boxes to tidy things away.
I’ve also got Aluminium Foil Tape to cover the working surfaces with to ‘bond’ transceivers to desks. This had worked really well when i done it with my TS690S and having the cables from the transceiver neatly on the metal conductive surface the cables was reduced loops massively.
So I will have a very busy weekend coming up to finish up my ‘week off’ but hopefully a shack that is not only free from QRM, but is also tidy and serviceable. I promise to upload pics 🙂
Was one of those nights when I couldn’t get my head down after a great Easter bank holiday weekend, so had a little play on FT8 in the small hours. Having used WSJT-X for quite some time I wanted to experiment with other FT8 software, and gave JTDX a try. I followed the setup documents and was soon transmitting and receiving. Some say JTDX has better decode than WSJT-X – I think time will tell.
Tonight (Or is that very early this morning) I had what must be the coolest FT8 contact yet tho
I have never heard of the “South Shetland Islands” until they appeared in the JTDX log – I was quick to click and respond, then patiently wait in the hope my call got responded to. Sure enough, with a few minutes and on 20 watts of power DT8A responded and my signal report was received. What I do with all FT8 contacts is to check the QRZ page and read up to add a little more ‘this is more than just a signal report’ to the QSO, I was amazed at DT8A’s page and the fantastic photos !
In particular as my good lady is South Korean, I found it very interesting that Mr Lee was stationed in such a remote part of the world !
So glad to have reached Mr Lee and I hope his work/research in the South Shetlands goes really well !
With the Easter weekend and good weather it was a good chance to get the multiband Yagi installed. It has been sitting in my garden since it was *missing parts* which then had to be ordered and paid for from the original supplier in the Netherlands.
I’ve had the rotator and coax for VHF/UHF for some time as well so was really looking forward to bringing it all together.
The rotator was purchased from Farnell, no longer available, but ‘RCA VJ226E’ may find some sources on the Internet. warning – my unit came from the US so requires a step convertor for UK usage for 240v -> 110v.
I really liked the instructions for the unit, clear and easy to follow, unlike the sketch-sheet of poorly presented documents that came with the GB-3 Yagi, which looked like something a DIY or student would put together. May the instructions from DX-Engineering on their Hustler just spoiled me..
I started with assembling the rotator indoors and checking the necessary parts. I didnt have a long enough run of coax cable for the feed line, but was quickly sorted out by a local dash to B&Q for “Time Black 3 core Multi-core cable 1.5mm² x 50m” – this is meeting or exceeding the specification required for the unit. I’m approximatting 10 meters of ground-feed and about the same going vertical.
Whilst the instructions used black/red/green, i swapped out for ‘live/netural/earth’ but the thing to ensure is that the colours both ends are the same.
Once I Had completed the wiring and had a clear idea of how to mount the rotator mast, i set about how to mount the yagi.
Because an extensive amount of time would be at about ground level I invested in a support so i could work at height with better saftey than just a ladder.
At £114.99 the Abbey 5 Way Multi Purpose Platform and Scaffold Combination Ladder from Amazon would do the job, and also allow me to work on the higher parts of the Mazda Bongo that I have.
Construction was simple enough with a few bolts and rods to put in place. I’m not a ‘light’ person and getting on the first time was a challenge. I used another smaller step ladder to get on and off, which helped. Using one end to get on and off from helped with usign the strength of the frame as a support.
Having got the working platform up, i mounted the rotator onto the mast, this wasnt as easy as I thought as some of the clip-sections blocked the rotator, but with some fine adjustments, was able to get the rotator on.
I went back over all the nuts and bolts at ground level on the Yagi to ensure they was of good tightness, and brought the Yagi over to the mast to assess how to raise it. With help, I was first able to attach the Yagi onto the mast. I checked it from ground level and could see that some cables would get caught so with help raised the yagi slightly up the support mast by about 1 foot allowing more distance for the cables on the Yagi.
I done some preliminary SWR readings using the Rig Expert Stick Pro. I bought the Stick Pro to accompany my HF AA-55 Zoom, which doesnt have 2m or 70cm capability.
For a first attempt I was happy with the SWR readings with no adjustments. I think the next step will be to connect different coaxes and measure their losses, which at VHF/UHF coax can have a real difference.
I’m looking forward to testing out the rotator and seeing how good the gain is on the antenna – with a J-Pole I was able to reach Blandford, Southampton and of course the local repeaters.
