G3RE operated by Mike G4ICC

Gordon, G3WOV.  Tom, G4CMG. Derek, G3XWD and me, G4IYK in Gravesend.

Summary

Traffic was fairly light because Tom and me were off to the REA South East District Meeting together with Spike.  This is covered in a separate post.  Very interesting day out.

HF Operating

We were all in agreement about the user experience when operating HF radio stations in the average urban environment.  This is becoming more and more difficult because of local radio noise interfering with amateur signals when compared with the receivers at Hack Green in Nantwich, located away from noise sources, in a rural environment.  There were times when we could not hear each other at all by the direct route, while signals were perfectly clear on the internet – providing a much higher quality experience.

The potential impact to this was part of the conversation and IMHO that would be to deter people from operating HF at home by making it more difficult to use – rendering the low-end transceiver virtually deaf on some bands.  We should really evaluate the deterrent impact of this on the short wave listener (SWL), beginners and novices just setting out.  On the other hand it will sharpen up the skills of the determined operator and push people to invest in more efficient kit.

We thought we may become dependent on the internet (which could be a challenge…)

Now we have established the problem it is time to look at what to do practically, both locally and nationally.

We think the future may lie in internet radio like hack green, or remote radio operation. A number of issues arise with this.  It will be difficult to wean off for a start but you will need continuous access to broadband and the cost of that is an issue in itself.  There are still technical challenges when tracking for example, receiving and transmitting on separate systems when trying to stay on the same frequency.  In practice this isn’t an issue if you can hear your own signal. Gordon mentioned various techniques to make sure we don’t rebroadcast the received signal.  For me it has forced me to look closer at Windows Audio Controls on the PC.  For others it has forced them to re-evaluate their own computers.

Both recordings made via the internet.  If you listen to the 80m recording the noise is present in the form of crackles.  A bit like a scratched vynil record.  On 60 it is much noisier due to conditions.  Mike says “Conditions not so good on 60M today.”

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.
