This weekend (15-16 June 2019) it’s time for another “Exercise Blue Ham” event – Exercise Blue Ham 19 on 60 metres. The RAF invites all full licencees to take part and make contact with their special callsigns.
While researching for club talks, I ran across the following link regarding the tropo scatter system used in the 1970s/1980s with eye watering ERPs. A few members will know about this system, however many new to the club may not:
14th Feb Woodford Park meeting is a chance for us to catch up on the various projects/activities we’re up to – in particular any follow ups to the Great Construction Contest but not limited to that.
If you’d like a short (5 minute or so) slot let me know.
Doesn’t have to be stuff – could be contest updates or how RADARC
contributes comms to events like 3 towers etc.
Also – what would you like to see and I’ll try and arrange?
We can take contributions on the fly on the evening if need be.
Min G0JMS will kindly bring along a RigExpert HF to VHF SWR meter (Digital display) RigExpert to show you and VHF to UHF swr power meter (Cheap unit) which includes frequency. He will also do a brief demo of Yaesu Fusion – Wires X technology RF paths permitting.
If necessary, I’ll bore you for a few minutes before the bottles and
tomatoes start flying:
Geostationary satellite project – es hail 2. Mike G4CDF (and possibly others???) is making the running on this one but I will present on his behalf a very short overview. iirc it’s 2.4GHz up and 10GHz down. tx/rx is based on an SDR transceiver (lime sdr mini).
Adventures with FT8 internals and taxi radios (generating FT8 tones by pulling a carrier around) – update. TBH anything that generates a stable carrier and can be pulled a bit maybe down to 1Hz resolution looks like it might work – eg. voltage controlled oscillator.
cheap RTL-SDR dongles (£15 delivered). Mine does work but probably better to get the real ones rather than fakes like mine.
short gnuradio demo (maybe)
We’ll have the ICOM IC7300 out for people to have a play with and the spectrum analyser.
Tea, coffee and biscuits will be in plentiful supply all evening.
It is with a tremendous amount of regret that I have to let you know that club member Stephen Coleman, G4YFB, passed away on Friday 4th January aged 66.
He had been battling cancer having been diagnosed only 9 weeks ago.
Steve was a supporter of the Club and recently had been helping Ray with the Intermediate and Foundation courses. Going back to the 80s, he taught the RAE course.
Also, he was a member of the Thames Valley Repeater Group (TVRG) and had used his software talents to provide modern programming software for old PMR radios we had for sale. Those of you that were into packet radio may remember that for a period most of the U.K. mailboxes used the YFB software.
A man of hidden talents who will be very much missed.
” It is very sad to learn of this news. Steve always had a lot of time for anyone. I know he dedicated a lot of time to writing the programming software for the VX-10 before TVRG set about selling them a couple of years ago. He will be missed. ” – Jonathan M0JSX / K6JSX
“Steve gave a talk to the Farnborough and District Radio Society In 2016 and always greeted me when he saw me at rallies. RIP Steve gone too early.” – Phil G1LKJ
“Sorry to hear the sad news about Steve, much to young.” – Min G0JMS
“I am very sad to have lost an old friend and enthusiastic supporter of everything. His dry sense of humour and ‘can do’ attitude was always an inspiration. He will be a great loss to the club and the wider Amateur community.” – Baz G8DOR
“I knew Steve initially through the talk on the Development of Radar and Virtual Radar he kindly did for the club in May 2017. From that it was clear he was a prodigious software talent developing his own ADS-B decoding software. He was very thorough in the prep he did for the talk bringing along examples of kit and demonstrating them. He made it look easy. Anyone that’s ever tried to demonstrate stuff will know, it’s really not.
He was completely self-taught in software. With the hard stuff he was tackling and the results he got, that’s quite remarkable. I was hoping to learn more of the magical things he was doing with TVRG particularly in the area of software for commercial PMR sets.
Someone with Steve’s talent, experience and kind unassuming nature getting involved with training was always going to be a perfect match. I will very much miss him” – John G4RD
