Hi All,

It is with great sadness that i have to read that John Branegan,GM4IHJ
died because i started to contact him early on OSCAR-6 and he was both
a great gentleman radio ham and a great engineer radio ham.

in

living

> Over the next 25 years he taught me everything from how to work out an
orbit

satellite
> tracking program from very simple ones that used EQX up to complex
> elliptical orbits  with footprints shown on a graphical map. He was ahead
of

some
> amazing programs for the ZX81 ,ZX Spectrum and Sinclair QL.
>
> Knowledgeable and strongly opinionated on almost any subject and extremely
> well read, with interests from ancient history and geology to Space and
> Mathematics.
>
> A very unselfish and generous person who supplied amateur radio equipment
> freely to others in countries who had no way of obtaining it so that they
> could operate on the new satellites. A lot of Russian satellite operators
> have benefited from John's generosity.
>
> A bachelor, surely no wife would allow a 6 foot dish in the livingroom for
> satellite experiments! His house was crammed full of radio gear and books.
> There were antennas in the loft, on the chimneys and in the back garden.
> Nothing very ambitious, because his small bungalow and garden would not
> allow them, but sufficient for him to study all the bands that interested
> him, from 15m up to 12GHz. He had a full size 3 ele 10m beam and 50MHz
beam
> in the back garden. He worked some good DX on 6m and also had the first GM
> to Balearic Islands QSO on 144MHz via Sporadic E.
>
> John spent a huge amount of time monitoring the bands, with several radio
> and TV receivers running on many channels looking for signs of anything
> unusual and was always the first to know that the band was going to open
up
> on SpE, FAI or Aurora. He would use many novel radio sources for examining
> the Ionosphere, including 'pulse stealing' from the 153MHz Wick Auroral
> Radar and the Fylingdales BMEWS.  Many times he would kindly phone me to
say
> that Norwegian Telly has just gone Auroral or getting a bit of SpE on Band
1
> from the south east possibly Arabic!

that

Africa
> are logged in his shorthand style. At various times he would become

> would know what was normal and what was abnormal. He was a true
experimenter
> and discovered many new things about the ionosphere in both the
> Arctic/Antarctic and the Equatorial regions from his observations in a
small
> Scottish village.

> He always embraced the new technological tools that became available with

doppler
> shift on HF satellite beacons at the antipodes. Weather satellite picture
> receiving software to look for signs of break up due to Es or Aurora.

different

> Although he much preferred the original analog VHF satellites to the
> digisats, he was never the less keen to gain all the knowledge on how to
put
> a digital satellite station together. He built PSK and FSK modems and
wrote
> helpful booklets on how to get everything configured and working.
>
> From 1989 to 2001 John wrote a weekly Satgen bulletin a grand total of 682
> Satgens! This was distributed worldwide by packet radio and then also on
the
> Internet. There was always something in these Satgens that was topical and
> practical and they are a mine of information as well as historical value.
> Every one can be found online at

>
> In the past year John had a heart pacemaker fitted and this curtailed his

> experiments.
>
> Always keen to talk to the youngsters in the village who all loved to come
> round to his house to find out things about fossils or volcanoes or Mars
or
> the War or... He had many watercolours that the kids had produced for him
> stuck up on his livingroom/shack wall beside a couple of large black and
> white photos he had taken on one of his Aircraft Carriers showing some
> dramatic pilot errors.
>
> John loved to educate others and would travel to Scottish amateur radio
club
> meetings and conventions to give guest talks on subjects from Satellites
to
> how the Ionosphere works. He produced booklets on his own printer, bound
> them and supplied them to whoever requested them.
>
> He had a deep interest in space and astronomy and was delighted to have
> witnessed those magnificent comets Hyakutake and then Hale-Bopp.
>
> As well as publishing numerous papers in AMSAT-NA Journal, John authored
the
> Space Radio Handbook published by the RSGB. This book highlights John's

space
