13th June: Radio Conditions as Predicted
On checking the predicted propagation using the chart provided at www.ips.gov.au for signals under 200Km at 3.5Mhz (80M) in UK, it was interesting to note that it did not list the frequency band as being supported. The experience today was along those lines although from where I was listening in Cheshire things were only slightly variable at times and I could only give good reports to everyone on net. The quality of the signals and audio received in Nantwich are excellent as you will hear.
Much better still. The conclusion I am drawing from these experiments are that your station needs to be pretty well designed and located to be immune from radio noise these days.
Sound and sound card issues
I did some fault finding when I discovered the audio from the WEB SDR was interrupted for a few seconds every few minutes. I found the Chrome Browser was the source of the issue, by using a tool provided by Windows called Resource Monitor. In the graph below it shows my computer processor locking up and the source coming from the browser – the orange trace. How neat is that for a fault finding tool? Now to find out why and whether or not it is regular or intermittent. I also have issues with windows 7 in being able to select sound outputs (Phones or Speaker). So its not all roses. Its a bit like HIFI I expect. You need good kit to appreciate the quality. I may invest in a decent soundcard and processing software as my basic equipment (Home made computer using standard parts) has several issues like I can’t record my own SDR. Gordon, G3WOV mentions he was transmitting on a different frequency to his receiver – a problem I found – lat week as there is no tracking between the PC and the Rig (Yet). I say yet because we are using crude equipment which is not yet fully developed. I don’t think this problem exists in remote transceivers.
On Net today, Jack G3PWK is restoring a valved B2 Spy set from WW2 and building a vertical dipole for a club member, Gordon G3WOV is out to a field day with his local club, Mike G4ICC is getting over his windows upgrade and delving into electronic log keeping and Tom G4CMG is enjoying his new computer.
Branch Matters Prevail
Short bulletin today – my main effort this weekend has been to update the regular army through the RE Command Support Branch (Many of us would know this as the Signals Wing). They wanted to know more about our branch and its goals. I must say it has been a privilege to start some very interesting communications at a senior level about the unique nature of our branch within the corps of royal engineers as a whole and which we have now followed up. Our update will be presented by our serving committee member, Jock McLay at their symposium this coming week and I have taken care to ask for feedback.
73 de Stu
Enigmatic to the core I went to school in Bolton and Manchester and ended up joining up at Manchester in '69 enlisting in the corps of Royal Engineers. My aspirations were quite vague at that age and I was persuaded to drive for a living and occasionally operate radios instead of flying fighter planes:). Having then learnt my trade and obtaining my centurion tank driving licence, my early career saw plenty of action on Soltau tank ranges and the obligatory tours as a radio op in the infantry and engineer roles in Northern Ireland -2 years all in. Operating the radio took my fancy (even after a four month tour following a super fit troop commander around on patrols with a 43 pound radio on my back) - it was something I would eventually be able to teach. After 20 years I ended up in the position of QMSI (look it up) before diversifying into an IT Role with HQ Engineer in Chief. This was early days for IT in the RE and having studied it in my spare time to an acceptable level - aided and abetted by an elmer with excellent skills on the BBC Micro (G3WOV, See also below) and the Nienburg Computer and Electronics Club, eventually I became a CIS WO - one of the first in the corps with any Command, Control, Communication and Information Systems Experience - qualifying as a systems analyst and amongst other things, training at the school of military survey in Geographical Information Systems. In the history of the corps IT was so new at this time, the laptop was only just becoming cheap enough to afford and there weren't many people around who had one in the military. But when the UN went into Bosnia it became an essential tool no officer could be seen without. When this was realised I ended up purchasing a roulement scale of IT kit and devising the first ever Windows and office software training course in the RE, and then delivering it as pre tour training package - with Alan Lewis (Wordperfect, SuperCalc and Paradox). It was in those days that Alan Lewis introduced me to CIX and Compuserve. (No internet, just dial up bulletin boards then). Interestingly when TCPIP took off with email I was offered shares fairly early on in Demon Internet - oh how I wish I had taken that up. There was then this period when data communications became fashionable and I remember working a rear link via 300 baud packet between Chattenden Barracks and the Falkland Islands in the early nineties. At least three hundred packets got through before the novelty wore off:) Not much of a record, but interesting to see how packet took off and declined in quite a short space of time and how TCP\IP has flourished - so much so that the address space has already filled up when it wasn't supposed to:) I took up amateur radio whilst serving at Tidworth in '78 due mainly to a great elmer, G3WOV. Here, besides breaking my leg and taking up shortwave listening, I did four jobs of note; Detachment to Cheshire Police HQ during fire strike - signals corporal, Married Gillian, passed the REA and Morse test and promptly after that found myself abroad monitoring a ceasefire in Rhodesia. The newly acquired radio licence came in handy as they kindly lent me a brand new PRC320 with which to practice on during those lonely nights in the bush (and live ammo). See here http://5820-99-114.com/TCRU/?cat=48 - After that I spent the next 10 years in 21 Engineer Regiment in Germany where I held and used the callsign DA1CY and then DA2DI (on the second tour). Occasionally purloining the CLANSMAN Kit for the odd QSO. While stationed in Nienburg I had the lovely experience of raising my daughter - Sammy and on the second tour my son Tom was born. They reckon it was something in the water. While here on the first tour I had a sked with VP8API (look it up) on 1.10.82. Ian was on tour clearing up after the Falklands war. Interestingly - while calling him on my 100 watt TS120S transceiver and dipole I was called back by 4K1A in Antarctica. I could not believe he gave me five and nine. The cold war being what it was I think the operator was curious because he was asking me where my friend was - (not obvious). Between tours in Nienburg I had the great pleasure of teaching TA Soldiers in 75 Engineer Regiment (V) radio skills - I think I took away as much learning as I imparted. Worked PRC349 to PRC349 from Snowdon to the Cat and Fiddle in Cheshire on Whip Antenna for a bet (work that one out). One memorable part of this was spending a great deal of time designing computer software with a really good RSO who could program in Basic to generate Slidex and MAPCO Keys. We finally nailed what must have been the most boring job in the army, and then they supersede it with BATCO. I had the job of converting the regiment to that. While living in Failsworth, I encountered a lifelong friend, Ian, G6TGO for the first time. We have had occasional skeds ever since - we are still trying to get the 351/2 to work between Gravesend and Manchester - (Close). Notably on my second tour in Nienburg I got the time to practice combat engineering in between radio stags and having got the hang of command and control using BATCO which was fraught, I analysed the radio messages we were sending during an exercise and noted how much time it would save if we formatted them differently - BATCO was a problem and it was costing the corps days and hours it would not afford in a war. On realising this I produced the first Engineer Secure Orders Cards (ESOCS) on my Amstrad PC using DTP. Uncannily surreal, but I also lived for a time in the same flat as Spike, G4AKQ but ten years or so later, and then after becoming good friends with him even more years later I discovered we had that in common when I read the address on his QSL Card. Now settled in Gravesend I had the honour to further serve in both the police and the NHS. Firstly as a network manager - how cool? Straight out of the army and straight into a network manager's job with the same money and a half again. Then one day I spotted a project of note with the police, as technical lead on a county wide rollout project for their Digital AIRWAVE Radio system. How time flies, they are now planning its replacement. Since then I have had many exploits with cost saving IT Projects for the NHS and I can see them replacing some of those systems soon. It will soon be time to retire however not before I save them another few million. Now I work for a mental health trust - I can see both sides of that particular coin having acquired a little black dog at some time in my career, which is not uncommon - I am so glad mental health and the military mindset have become hot topics for discussion :) Check me out on Facebook and LinkedIn. My favourite quote: "What the fcuk do the engineers know about IT and communications?"
Will let you guess where that one came from :). Having used and taught LARKSPUR, CLANSMAN, and now glimpsed the Bowman Radio Systems (which was being specified as I was in EinC) I realise that just about everything I have worked on in the Army, BATCO, MAPCO, Slidex, Griddle, VP, SOCs Morse Code, Map reading and Marking skills have been digitised and encrypted to the Nth degree. That's why I am creating a digital record, - before I become obsolete myself or worse - TRON.
