GB3BN net summary 9th April 2020

Wonderful to hear so many people on BN again. Here are a few of the salient points:

Great discussion about birds and wildlife. Some thoughts there may be changes in red kite behaviour in that they may take small prey. Robin G4IWS reports on turf wars over his nesting box; nuthatches involved. Graham G3XYX reports it’s great to hear the song thrushes in full voice.

Lots of projects on the go, too many to mention – Tom M0LTE using ammo cases as enclosures/housings; Loz G2DD looking to calibrate his power meter. Simon fixed an IC260 2m rig – dead ‘OR’ gate CD4071 IC I think it was and is now being driven mad, like me, by a microwave modules transverter.

Big shout out to Gareth M7GRB for supporting our carers by 3D printing face shields.

On that front, remember there’s the RSGB ‘Hope’ QSO party (can’t remember who mentioned that): https://www.rsgbcc.org/hf/rules/2020/rhqp.shtml

Min G0JMS has had a shack tidy, or so he claims 🙂

A possible talk we could look into is Dud Charman G6CJ’s Aerial Circus – or recreation thereof.

Dave’s WIRES-X/Yeasu fusion gateway MB6IOX is there for all to use (https://www.ukrepeater.net/my_repeater.php?id=3214). Min and Gary G4FLY also have gateways.

A source of RF noise found and summarily shot: a talk talk router and possibly a USB charger.

John bemoans the lack of the old GB3RAL beacons (28.215, 40.050, 50.050, 60.050, 70.050)MHz and GB3BAA on 50.016MHz and 70.016MHz and wonders if RADARC might be able to support at least getting something back on air in the lowband VHF region.

Here is the full cast list, with signal strength in dBm on the BN input at Bill G4WJS’s location in Stokenchurch (where recorded):

Tom M0LTE (-125)

Graham G3XYX (-109)

Chris G4CCC (-103)

Mike G4CDF (-118)

Chris M1CYE (-128, then -120)

Michael M0MPM (-122)

Bill G4WJS

Jim G0LHZ (-125)

Simon M0ZSU (-121)

Andy M7ANR (Fleet) (-124)

Loz G2DD (-128)

G4ZRZ (sorry – didn’t get a name, could have been via echolink)

Robin G4IWS (-119)

Min G0JMS (-99)

Dave G0TKV (-102)

Gareth M7GRB

Vin G4JTR (-100)

Gary G4ELD

Thanks to Bill for the signal reports on the input.

GB3BN net 8pm 26th MARCH – A Summary – thankyou!

On the evening of what should have been the spring junk sale 2020, postponed due to COVID-19, we had a net on GB3BN with 23 stations joining. Now, more than ever, communication is important . We did that in spades.

I thoroughly enjoyed running the net. It was fantastic to combine getting on the radio and having a club meeting. Looking back, we really did that using the technology we love. At 8pm, I didn’t know that would happen. All I had was a beer and the radio by my side. By 10:30pm I had a list of 22 callsigns (with ticks against them, finally, to indicate signout) and it really felt like the end of a normal club meeting, or even better because everyone took part and contributed. This virus will not stop us.

Operating procedures were first class. Everyone. No exception. New M7 operators/callsigns? Flawless.

Because it was so productive, I thought I’d try and capture a few points.

Firstly, it was wonderful to be able to collectively say THANKYOU to our magnificent NHS together, on air, using BN’s huge coverage area.

Other:

  • In these uncertain times, this net is a place where we can all gather on 2nd and 4th Thursdays where we would have had a face to face club meeting. To ‘check in’ if you like.
  • Following on from the BATC’s support for online meetings and their offer of support for clubs, it is clear they are something RADARC needs to pursue. In particular, a number of members enjoyed Noel G8GTZ’s QO100 talk.
  • Lots of practical tips for surviving the ‘lockdown’.
  • Finding out about other nets (eg. G1RAF has a net on GB3TU 433.225MHz: 12:00 and 19:00 daily).
  • Discussion about new conferencing technologies: eg. zoom, discord.
  • Propagation news: HF, VHF. There are some signs Sporadic E is starting on the high HF bands and 50Mhz. The Poldhu net on 80m was in fine fettle.
  • Virtual sharing of beer and biscuits (Jammie Dodgers no less) in the finest Reading tradition. (There should be bulbs in there also – gardening did feature).
  • Updates on construction projects – reports of exploding tantalum capacitors.
  • The trials of home working.
  • Clarification on how the local repeaters work with CTCSS. You get a ‘T’ in morse if you’re running CTCSS, ‘K’ otherwise. Soon, I think, you’ll need to run CTCSS. see http://www.tvrg.org.uk/ for details.
  • Our ‘YouTube’ channel with videos of previous talks (thanks to James 2E0JPM) is https://www.youtube.com/channel/UChamISEy8HRvKmWN0-GTWpA
  • Loads more. If I’ve missed anything you would like included here then please let me know.

Thankyou for a special evening.

Apologies for getting any callsigns wrong. Now you can see why. The raw material for this post.

6 more intermediate passes!

I am delighted to announce further intermediate level success at RADARC.

Graham Walker, M7MRG

John Holden, M7AHY

Kim Hiscock

Ray Brown G3SCZ (RADARC training guru)

André Broodryk, M7VWB

Graham Aisbitt, M7GRA

James Wynne

Ray’s T-shirt says ‘I can explain it to you, but I can’t understand it for you’. Clearly both activities happened with great success so well done to all!

A particular thank-you to Ray for all the preparation and hard work that goes into making events like this happen – also to everyone supporting him.

Callsigns to be updated in due course.

73, John G4RDC.

Solar orbiter talk postponed

Chris Brockley-Blatt is unwell so the Solar Orbiter talk planned for this evening is postponed.

We will still meet at Woodford park for a natter night and chance for anyone to do a short talk if they wish.

We will also have a go at the 50MHz UK Activity Contest

“ACE HIGH” Tropo Scatter system

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:

Like Graham, G3XYX I have visited the Stenigot site in Lincolnshire wolds (in itself an incredibly beautiful place) – sadly only one dish remains now. Possible club talk if anyone knows a speaker…?
