Quick LNA4ALL test

Despite the best efforts of the Royal Mail service, I have been able to get my hands on a Low Noise Amplifier created by Adam at LNA4ALL. The Royal Mail showed just how useless it is, when the parcel arrived here in the UK in just 11 hours from Croatia on February the 14th, but then not getting delivered to me until March the 14th – yes, one month! There is no surprise that courier companies such as DPD and Hermes are getting more business than the Royal Mail – they are bloody useless.

Anyway, the reason for the purchase is for a later review on an AIS dongle that I will be testing, but which has unfortunately been possibly damaged before getting to me.

So, as I had some time to spare I thought I’d run a quick test on how the LNA performs against the claims that is shown on the LNA4ALL website. For the test I used a quickly built 12v to 5v PSU that was connected to a Maplin bench PSU and also a Rigol DP711 Linear DC PSU where I could ensure a precise power input. As it was, it was good that I used the DP711 because my quick PSU was only chucking out 1.2v at connection to the LNA4ALL, despite an unconnected output of 5v – some work needed there I think.

Despite this lower power the LNA4ALL still worked with just the 1.2v input, though the results where not as good.

Other equipment used were a Rigol DSG815 Signal Generator and a Rigol DSA1030 Spectrum Analyser (no longer available), along with various Mini-Circuits shielded test cables. The Rigol equipment I purchased from Telonic Instruments Ltd last year.

Below then is a table that contains all the relevant data. As you’ll see the Gain claim is pretty much spot on with some being over. Just a couple of frequencies are below that which is claimed, especially at 28 MHz.

LNA4ALL Frequency data

A couple of things to note.

Firstly, somehow I managed to miss testing 1296 MHz. I obviously didn’t put it in the table in Excel before I started 🙂 Also, the DSG815 only goes up to 1.5 GHz so I couldn’t test above that.

Secondly I ran a test for the AIS centre frequency of 162 MHz, for which there was no comparison to the LNA4ALL data. A gain of over 24dB though shows that the LNA would be perfect for those of you with AIS receivers that may want to get better reception. To prove the theory I compared the LNA reception against data without it connected to the NASA Engine AIS receiver that I currently use. In ShipPlotter I average a max range of around 15nm without the LNA, but with it connected this increased to around 22nm. The number of messages received also tripled as it was able to dig out the weaker signals.

The NASA Engine isn’t a bad receiver, but it is a frequency hopper rather than a dual monitor, and so it changes between the two AIS frequencies every 30 seconds (161.975 MHz and 162.025 MHz). I suspect a dual monitor would give better message numbers and range.

Below is a graph made using the excellent software by Neal Arundale – NMEA AIS Router. As you can see the message numbers (or sentences) for over an hour are pretty good – well, it is a vast improvement on what I used to get with my current “temporary” set-up, with 419 messages received in an hour. The software is available at his website, for free, along with various other programs that you can use with AIS. If you’d rather not use ShipPlotter he has created his own AIS Decoder which can be linked into Google Earth and such like. Visit his website for more information.

My antenna isn’t exactly top-notch. It is at a height of just 4 metres AGL in the extension loft, and it is made from galvanised steel angle bead used by plasterers to strengthen corners prior to skimming – this I cut down as a dipole for a target of 162 MHz. As usual with my trimming of antennas, I cut just too much off and ended up with it cut to 161.167 MHz. It gives a VSWR of 1.018 and Return loss of 40.82dB, with 162 MHz being approx. 30dB Return loss which equates to 1.075 VSWR – that will do.

Also, as I live right on the coast, about 50 metres from the sea, I’m practically at sea level, which doesn’t help much with range and signal reception either. Despite this the antenna produces great results, though it is just temporary until I can get a new homebuild up on the roof.

The LNA4ALL retails at various prices depending on what option you go for. I went for the aluminium box version so it was around £54 including the delivery. I had looked at a Mini-circuits equivalent, and when it looked like the LNA4ALL was lost I did actually order one. But this was nearly twice the price, and seeing as the LNA4ALL contains many components from Mini-Circuit I doubt it is any different really.

All in all the LNA4ALL is all you need to boost your weak signals – couldn’t get any more all’s in 🙂

Stamps of Radio Stations by Continents and Countries

At the end of November the SWLing blog had a post about collecting postage stamps with a connection to radio.

I’m by no means a proper stamp collector but the reason I found the blog of interest was because in August I had actually bought some First Day Covers and a Mint set of stamps commemorating 50 years of the BBC on Ascension Island. I had been stationed on Ascension in the 90’s whilst in the RAF and I spent quite a lot of my days off at English Bay beach which is right next to the transmitter site. Plenty of good memories.

The SWLing blog was about a Word document created by Lennart Weirell of Sweden. He has been able to collate a list of all the stamps that has a connection with Broadcast Radio and turn it into a twenty-four page document. It lists the 125 countries that have produced such stamps and the information includes date of issue, the Michael number, value (at issue) and name of the stamp. There are also tick boxes so that you can mark off whether you have these stamps in your collection. stamps

It doesn’t say this in the document but you can however go one step further than the tick boxes. If you have a scanner, just scan your stamps into a picture folder and then create a link to each relevant picture in the Word document. It’s as simple as highlighting the stamp name for example and then clicking on the Hyperlink button in the Insert tab group of Word (you can also use the Control-K shortcut). Just find the picture folder and the scanned image and link them up. As long as you don’t change the image location, each time you go to the Word document, clicking on the link will open it up.

The Word document is €4, but contact Lennart by email first so that he can send you a PayPal invoice. His email address and further information about the document is available on the image above.

The 50 years of the BBC stamps are available from the Ascension Island Post Office website.

TitanSDR Pro demonstration

After receiving quite a few requests on information about the Enablia TitanSDR and it’s capabilities, I decided it would be good a good idea to create a demonstration video that would hopefully show just how good an SDR it is. The video is at the end of this blog.

I think that a lot of people can’t understand just why the two versions are the price they are, especially when it seems that a new dongle SDR is being evolved every day at a ridiculously cheap price. Yes, they are expensive but when you compare the price of these SDR’s to a top end desktop receiver, such as the Icom IC-R8500 for example, then it is fairly comparable.

But you must consider the fact that the Titan is really more than one receiver. The Pro version is 40 receivers, the standard is eight. You can’t record independently using the Icom, you need some additional software or a digital voice recorder plugged in to the receiver; and even then you can only record the one frequency – the Pro can record 40 frequencies, the standard can record eight.

The TitanSDR Pro can monitor up to 40 frequencies at the same time. Here, 10 frequencies are being monitored, mainly Oceanic ones.

The TitanSDR Pro can monitor up to 40 frequencies at the same time. Here, 10 frequencies are being monitored, mainly Oceanic ones.

Then, you can’t really record any bandwidth to play back using the Icom, but both versions of the Titan can record up to three separate bandwidths. These can then be played back, either through the SDR itself, or on another PC using the supplied USB dongle that carries a second version of the software – and if you did this you could be listening to, or recording, further frequencies or bandwidths. And all these separate bandwidth recordings can, of course, be played back multiple times, with multiple recordings being made within them; or data can be decoded; or signals analysed – what ever you require from an SDR.

This image shows the Titan monitoring 12 frequencies, 6 of which are decoding ALE using PC-ALE. This can take place in the background, while listening to the other frequencies on the SDR.

But, of course, this is just standard for any SDR isn’t it?? But is it?? Can you think of another SDR that has the capability to monitor/record 40 frequencies at once? I can’t.

The nearest SDR I found to the Titan in quality of not only recording capabilities but in quality of filters etc. meant that I would need to buy around 13 SDR’s of this model and spend over €30,000. Yet, just one of this model costs pretty much the same price as the Titan. Now, with that knowledge, the price of the TitanSDR’s really doesn’t seem that bad after all.

Don’t forget, the TitanSDR is a Military spec. SDR, designed originally for agencies to monitor multiple frequencies for analysis and data collecting. It already has top specifications but Enablia are still willing to listen to the users and add requested features if they can. They have already done this with quite a few ideas that myself and other users have suggested.

You'd think that the Titan would be a CPU guzzler wouldn't you? Well it isn't. Here the SDR is running 31 frequencies, multiple decodings using MultiPSK, and PC-ALE. The CPU is running at only 27%, and that was it's max reading.

Canon 5D update

Before going any further, just a quick update on the repair to my 5D that I carried out in my last blog

Unfortunately, it only lasted about another 200 shots before the mirror became unstuck. So I decided to purchase a new 5D mk III, but before I did I looked in to how much it would cost to get the current one repaired to either then consider selling on or to give to my girlfriend who is just starting out in photography. I decide to search locally, choosing Glasgow as the nearest biggest place to start. Straight away I found a company called A.J. Johnstone & Co. so I gave them a ring to find out the bad news. AJJ

Well, it turns out, all that information I’d previously reported about the cost of repairs was total rubbish. As it’s a known Canon fault the repair is free!! The only cost was for the postage. Well, this was great, no new camera needed. I sent it off the next day by courier adding a note asking to give the sensor a clean; and one of their team rang me the day after that to confirm I’d pay the £38 for the sensor clean plus £10 postage.

Not only did they do the repair and sensor clean, they also replaced the focus screen, updated the firmware and gave the camera a good clean externally. I highly recommend using them if you need to service your camera. The sensor cleaning service is same day with no prior booking required if you’re able to go to their premises. I was without my camera for about 6 days in total, including the postage days.

Their website can be accessed by clicking on the image above.


With the recent Joint Warrior exercise having taken place here in the UK I thought I’d mention the NAVTEX decoder I use for getting information on where some of the action may be taking place. Why use NAVTEX? Well the Royal Navy, in conjunction with the Queens Harbour Master (Clyde), produce a twice daily warning on Submarine activity off the west coast of Scotland. This is due to a fatal incident in 1990 involving a fishing boat trawler and a dived submarine which unfortunately got snagged up in the trailing net. SUBFACTS, as it is called, is broadcast twice daily on the NAVTEX frequency of 518kHz at 0620 and 1820 UTC and it gives the approximate location of any submarines that are operating within the next 24 hour period. Also included in the broadcast is information on any live firing that is taking place in the danger areas on the coasts and at sea off western Scotland – this is known as GUNFACTS. Further information can be found here

Anyway, back to the software I’ve been using recently. This is the Frisnit NAVTEX Decoder created by Mark Longstaff-Tyrrell and it’s totally free. Not only does it decode NAVTEX messages, if you register the decoder (still free) it means you can upload your receptions to the frisnit server giving them access to anyone. The main aim of this is to provide people at sea with the ability to check NAVTEX messages without the need of having an actual decoder on board. As long as you have access to the internet you can access any uploaded messages. And you don’t need to upload messages yourself either, the messages are freely available to anyone, even if you don’t have the software yourself.

As you can see from the image above, as well as a raw data view, there’s also a messages view. All the completed messages are stored on your hard-drive giving you the ability to go back through all the messages you have received.

As well as using NAVTEX for getting the submarine information, it’s also a very useful tool for getting accurate weather forecasts, especially if you live right on the coast as I do, and doubly especially if there’s storms brewing out over the Atlantic.

There’s other features available on the frisnit website, so if you’re interested in NAVTEX take a look, and even try the software. I don’t think you’ll be disappointed.

The Spectrum Monitor article

tsmcoverI’ve recently had another article published in The Spectrum Monitor. The subject of the article is monitoring the Russian Air Force Strategic Bomber networks on CW and USB. It was good fun to write, but also quite complicated as it’s one of those subjects that can be hard to explain. Anyway, I think it has been received well.

The “magazine” is available as a single edition for $3 or why not subscribe for a year for $24 – that’s $2 a month for around 100 pages of great articles. There isn’t another Radio magazine that can offer such great value, especially here in the UK.

DIY Canon EOS 5D Camera fix

Canon Eos5D(mk1) DIY fix

There I was on a harbour tour of Portsmouth, snapping away at the (large) amount of RN ships docked there at the moment, when my 5D made an awful clunking, grating sound and stopped taking images. Looking through the viewfinder gave me nothing but darkness. After a brief panic, I took the lens off and sitting in it was what looked like the shutter mechanism from the camera. Luckily I also had my 50D with me, so I was able to continue with what I was doing, but as soon as the time became available I took another look at the 5D

As it was, it turned out it wasn’t the full mechanism but just the mirror that had come unstuck, so the thought of huge amounts of money flying on to my credit card stopped as I thought it would be a reasonably cheap fix. I did wonder if the previous weeks wet shoot of HMS Duncan may have been the cause. It had been a wet day, but the camera hadn’t got seriously soaked as I protected it. It was, however, also quite humid, so I think the two weather patterns and the clunking process that shutters have to go through combined to unstick the mirror a little. This final shoot was enough to let the mirror lose it’s grip completely


Back home a few days later and I investigated the price of getting the mirror put back on. I was shocked to find that the price for this repair was ridiculous, prices between $250 and $500 were being quoted by people with the same problem in the USA (I couldn’t find a price in the UK). This was crazy, and I seriously thought that at that price I may as well look for another 5D

But then I thought, well I may as well see if a bit of superglue to the back of the mirror will work. So I Googled to see if others had tried this, and they had, and it had worked

So this is this is the process I carried out to make the DIY fix.

1. Obviously, make sure you’re in a clean area, with as little dust as possible

2. On the back of the mirror is a small black piece of thin plastic, take this away. There’s no need to remember or mark what way round it goes as this is obvious by the holes

3. Cut the end off a cotton-bud

Remove the black plastic and cut off the end of a cotton-bud

4. Get the superglue and squeeze some out onto a piece of paper, card or plastic – whatever you have available really. DO NOT squeeze superglue directly onto the small pads on the back of the mirror, we all know that superglue has a mind of its own and is hard to control in small amounts

5. Take the cut end of the cotton-bud, scoop up a small amount of glue and dab it onto one of the small pads on the mirror – you don’t need too much. Repeat this for the other three pads, but do it fairly quickly before the glue can dry

6. Return the black plastic to back of the mirror

7. Look at the shutter mechanism of the 5D and note the correct way round the mirror should go by the position of the indents for the pads

8. Gently place the mirror on the shutter mechanism, applying only a small amount of pressure

Mirror fixed back in place. Now let the glue dry followed by a clean

9. Close up the camera with the lens cap and leave it for a few hours to dry properly

10. After a few hours, test to make sure the camera works correctly and the mirror stays in place

11. Give the mirror a clean as its bound to have some fingerprints on it

This took me about 5 minutes, and cost the price of one cotton bud and a tube of superglue – both of which I had already

Cross Country Wireless HF/VHF/UHF Multicoupler

With the total rebuild of the radio-shack looming I’d been investigating on a Multicoupler for my VHF/UHF radios. My homebuilt antenna connected to my Bearcat UBC-800XLT is far better than the bought Vertical Antenna that is connected to my Icom IC-R8500 so I wanted to remove the vertical antenna (using the co-ax for a homebuilt AIS antenna I’ve been testing in a different location) and use the Bearcat antenna on multiple radios

I’d found a few Multicouplers that suited, but after a discussion on MilCom about different ones, and a recommendation on one of my choices, I decided to go for the Cross Country Wireless HF/VHF/UHF Multicoupler multicoupler

I wasn’t the only one as I know at least one other member of MilCom made the same choice

There was a slight delay in delivery as Chris, the owner of CCW, was away on holiday. But as the units are made to order this wasn’t a problem to me at all

When the Multicoupler arrived I put it to use immediately and was very pleased with the results. It does have to be powered by a 12V adaptor and I had one of these spare, it can go down to 7V I believe, but either way power is required or you’ll get nothing. I ran the Multicoupler with the two radios, and even added my UBC-3500XLT to it too, with no loss at all. Very happy indeed.

However, a problem did arise. For some reason, reception would drop off over time. A quick chat with Chris bought about the probability that it was the power unit as he tests everything before sending out. Using another power supply the problem was fixed – initially. After a few days the same happened again, with great reception at first but then a drop. The power supplies I used were of the same make, so I queried it with Chris and he told me of a supply they have available that doesn’t seem to have any problems at all. So I purchased this too, and a few days later it arrived

Since then I’ve had no problems at all, and I am very pleased with it. I have only used it for VHF/UHF, not HF, so I can’t give any critique on its performance in this area

Temporary placement of the Multicoupler for testing

The HF/VHF/UHF Multicoupler is priced at £119.95 plus shipping (£8 in the UK I believe)
The 12V power supply is £20 including postage to the UK

Further details and specifications are available on the CCW website

The Spectrum Monitor articles and the MilCom Forum

I’m pleased to say that I’ve had two articles published in the July edition of e-Mag The Spectrum Monitor

The first article is about the Joint Warrior exercise that took place in March/April this year, and how and what to listen out for when these exercises take place twice a year in the UK. I wasn’t expecting this article to be published until September so this was an added bonus this month

The second article is about how I got into listening to Air Traffic Control and how this then took me down the road to becoming an Air Traffic Controller, an aviation/military photographer and writer, and into monitoring the radios in general – in particular HF

As well as the articles, there’s about 11 photos of mine included alongside. I also provided the cover image.tsmcover

The magazine is available either to buy individually at $3 each or by subscription for $24 for one year. Either way the magazine is well worth the money

MilCom Forum

About a month ago now, a new forum was created for the Military Monitoring enthusiast – MilCom

The main aim of the forum is bring together those of us that are interested in monitoring Military Communications, be it VHF/UHF, HF, CW, data, SATCOM etc. The posting of radio logs is actively encouraged. In just a month the membership has passed 110 with posts already at 850+; and this is without any real advertising of the forum. One thing you’ll notice if you head over, is that it isn’t just about Aviation. The forum covers all areas of Military Communications – Aviation, Maritime and Land (Space too if you really want to)

As well as the forum area there is a database section which contains information on Military Callsigns, VHF/UHF frequencies, HF frequencies and other things such as common abbreviations and terms used by the Military. There’s also an interactive map. These databases are updated almost daily by a team of us, and can also have anything missing submitted to the team for addition once confirmed. The databases are continually growing, are more accurate than any printed publication (which is generally out of date the day of printing) and more importantly – FREE

The only proviso to this data being available is that members participate in the forum and do not just “lurk”. The membership is continually monitored by the team and trimmed if necessary. That being said, we are a friendly group so don’t let the rules put you off – instead join up and participate.


With everything else that’s been going on, I totally forgot to do a blog on my new antenna set-up; and when I say new it’s now nearly 12 months old

My old set-up wasn’t too bad with a longwire stretching from the study and just tacked on to the top of the fence and wall around the garden, then from an old washing-line pole to the corner of my garage at the far end. This created a horizontal L shape with a slight incline. Reception was very good although as the antenna wasn’t earthed there was a bit of noise. Luckily I live fairly remote so there isn’t the usual interference from neighbours TV sets etc, but I wanted to improve the signal by creating a better set-up.

As a back up, I also had a Garex Compact Active antenna in the loft which I also wanted to move outside. This is a great active antenna, designed initially to be used on small boats and was perfect as I live on a harbour and have to cope with the same atmosphere and conditions that would be found at sea. Corrosion of metal is a big problem due to the conditions around here, and this was evident in the longwire.

With this in mind, I selected Military Spec. Kevlar Antenna Wire from Nevada Radio. Not only is this wire weather proof and light, it is green and will blend nicely into the background around here, just like camoflage (another reason why it’s used by the Military). It is also incredibly strong, and once tensioned will not stretch like standard wire

Mil. Spec. Kevlar Antenna Wire

I also ordered a few other things including 100m of Military specification RG58C/U coax cable, some Ceramic Insulators, plugs and sockets. Nevada have never let me down and I can recommend them totally

Prior to all this, in a general conversation with John who supplies me with my firewood I mentioned how it would be great to have an old telephone pole to use as the main mast for my antennas – “well, I have loads of them” he says. So when it was time to get it all together in the New Year, John delivered the pole, all 8 meters of it!

Telephone pole after delivery

The design was simple really. It would be the longwire stretching from the house in an L, with the down side running down the wall, connecting to the Co-ax, which would then run into the house via an air brick. Grounding would run from the co-ax connection to a copper rod driven into the garden. There would be a splitter in the loft space which would then feed both my Icom IC-R8500 and SDR-IQ radios.

The Garex would be placed at the top of the pole and the co-ax would then run along the wall and fence to the house; and in through the same air brick. The co-ax would continue through to the Icom as my second antenna

With rough calculations I realised that with a pole of 8 metres in length, I was going to need a pretty deep hole to put it in. BT use a screw type thing to dig the hole to the correct depth for their installations, but I didn’t have that, just a spade. 8 metres was too much anyway so I decided to cut off about a metre and calculated that around a 3 foot deep hole would be ok, with 6 bags of quick drying cement to firmly secure it in.

Garex attached to the pole

First of all though, I needed to attach the Garex to the top of the pole as I didn’t fancy doing that once it was upright and in the ground. Far easier to connect it all up and then plant the post into the hole. There are the usual steps attached to the pole which would be ok to use for general maintenance but it was going to be hard work getting the screw bolts into the solid wood of the pole that were needed to secure the mast mount.

Longwire clamp and step

With the Garex mounted and the cable run complete, it was then time to turn to the longwire. Again, it was going to be much easier to attach first and then raise the pole into position. BT had left the wire clamp on the pole so after a bit of a fight to get the bolts out that connected this, I was able to service them by wire brushing off the rust and corrosion before reconnecting them with some copper grease added to stop any further rust. To help secure the wire a bit better I first threaded some garden wire through some yellow/green earth sleeving which was then fed into the clamp and I then put the wire through one end an insulator. Then I fed the longwire through the other end of the insulator and tied off the wire using a standard camping guyrope tensioner, as unlike conventional wires that you wrap around itself the Kevlar wire uncoils due to its great flexibility. The tensioner butts up against the the insulator stopping the wire from going through the hole

So with both antennas attached and the hole dug, it was time to get the pole up. This turned out to be very easy, and with some assistance to hold it steady and totally vertical, I poured in the 6 bags of quick drying cement. After about 10 minutes it was ok to leave the pole on its own, and I waited a further two days before stretching the longwire across to the house

Whilst I waited those two days, I carried out the remaining tasks of getting all the co-ax in place and fully connecting the Garex to the Icom. Already, with the Garex, I could tell the difference that the new location made. The noise floor was much better, and there was no interference at all from anything electrical. The co-ax and splitter were all connected and the run down to the study was also completed, although I had previously needed to rearrange my whole desk to get everything in a better position in anticipation of this project



Prior to the desk change I needed to stretch quite a way to the Icom, normally needing to stand up, but now I can just adjust from my seat as it is within half an arms length. I had also connected up an old NAD amplifier and two NAD speakers to the SDR-IQ via the second soundcard in my PC

When it came to the final connection of the longwire to the co-ax, I just used a standard chocbloc, placed inside a waterproof electical box available from most DIY stores. Getting the wire nice and tight wasn’t a problem using an insulator at the corner and end of the L, and I left a little slack to feed into the waterproof box. The earth rod was connected by some old wire to the outer shield of the co-ax and we were good to go

The results were excellent. Nice clear signals with hardly any outside interference. I get the occasional trouble with electricals, normally my own PCs, but in the modern world this is hardly surprising (or avoidable). The longwire runs almost exactly North-South, which is perfect for what I normally listen too – Russian Navy and Military transmissions, but it’s also perfect for getting the Ocean traffic and USA

Overall, I’m very pleased with it. With the use of an old telephone pole and green wire, the whole antenna has basically disappeared into the background. After some chats with neighbours most hadn’t even noticed it had gone up. In fact, one even said they thought it had been there for years
