CDARC (Cambridge) talk

Last evening, the Cambridge radio club had another Zoom talk, this time on the monitoring station at Baldock. 

This time, we also had a viewer in Russia! On previous times we have been watched in Canada and Northern Ireland. In all, 29 people attended.

Zoom has exceeded my expectations. Attendance is at least as good as a face-to-face meetings. At least with Zoom, the whole world can watch!

Another CDARC Zoom talk

The Cambridge radio club has another Zoom talk at 2000z tonight. These have all been excellent. 

Tonight's talk is on "Operating from South Atlantic Islands" by Martin G3ZAY.  I think he writes the HF column in RadCom, the RSGB magazine.

I have been pleasantly surprised how effective these talks are. We can all see each other and most sessions have at least as many people as a face-to-face meeting, with the added advantage that those people far away can still take part.

Some months ago we had a quiz with a club in N.Ireland and we have had members in Canada and Germany at times.

Details of CDARC are on the website.  See http://www.cdarc.org.uk/ .

CDARC AGM via Zoom

Last night, the Cambridge radio club (CDARC) held it AGM via Zoom. With 25 "attendees", it was very successful. Next year, assuming the Covid-19 pandemic has ended, I expect we will meet in person again. Once again this proves to me that we can always find a way.

The Cambridge club has held lots of talks using Zoom, and they have all be great.

Another successful Zoom talk

Last night, the Cambridge radio club (CDARC) had another well attended Zoom talk. Yet again this included a member in Canada. The talk was by Ray G4FON on learning Morse code, using his highly successful training course based on the Koch method. The secret seems to be to hear the sound of the letters much as a foreign language and not to try to write it down.

I am a great fan of Zoom as we can enjoy the talks from the comfort of our own homes. Also, people around the world can take part. Of course, by holding "virtual" meetings, we miss the face-to-face contacts, but Zoom with video is far better than I expected.

Cambridge Radio Club (CDARC) and Zoom

Like many, CDARC has been using Zoom video calls to continue lectures and, last week, for a quiz. I have been very impressed. 

At first, I wondered how this would be, but with 15-30 people typically and screen sharing it has been every bit as good as attending in person. In my case it saves a 26 mile car journey in the dark. Instead I can take part from home. 

The club has even shared meetings with a club in Northern Ireland and last week we had someone in Canada.

Several Zoom meetings with old work mates have also happened with Zoom. Although some are complaining of Zoom Fatigue, I can't agree. To me, Zoom has been an eye opener. I hope CDARC continues to stream lectures by Zoom, when the pandemic is a memory.

This might appeal to the geeks here!! It was first posted on the Cambridge Radio Club's FaceBook page.

My maths is so rusty, so I am unsure if this is correct. I think it is.

Very clever.  I guess the originator started with the answer, then worked back.

2007 Photo

Yesterday I was sent this photo of me. It was taken in 2007 on a 2m contest with the Cambridge Radio Club (CDARC). I remember going along, but don't recall the photo.

CDARC 2m FM Net 145.55MHz - Wednesdays

 This net is being resurrected by 2E0WDN, Steve. It meet at 8pm.

Cambridge Radio Club (CDARC)

In the last few months I rejoined the Cambridge club as a country member. Meetings are currently held as Zoom meetings online and these have been very good. I do not like driving far, if at all, at night these days. Zoom meetings suit me well. This week, we had a joint quiz and social by Zoom with a club in Northern Ireland. This worked out really well.

Cambridge club Zoom talk

Since lockdown, the Cambridge club (CDARC) has been unable to meet. Instead they have had a series of talks online the latest of which is tonight. 

I have to say, they have all been excellent. So much so, that I rejoined CDARC as a country member. Zoom talks work well for me as I do not have to travel 26 miles at night in the dark. Details of tonight's talk are on the CDARC website.

CDARC (Cambridge Club)

Way back in the 1970s I lived in Cambridge and was a regular at our local club.  At some point I was on the committee.  I now live 12 miles out and do not like night driving. Since the lockdown, the local club has had virtual meetings via the local 2m repeater or Zoom. Once again, I can take part. This actually better for me! I have rejoined the club as  a country member.

Cambridge Club (CDARC) Zoom meeting

As the Cambridge club cannot meet as usual every 2 weeks, it is meeting virtually instead. The last sessions were on the local repeater GB3PI with the prior approval of the repeater group. Tonight there is a talk with slides by Gavin M1BXF which is on Zoom.

UPDATE 2152z: It was excellent.

2m nets

In these difficult times there seems to be a bit of an upsurge in nets as people find new ways of keeping in touch.

Last Friday, our local Cambridge club (CDARC) had a very successful club meeting "virtually" via the GB3PI repeater with the agreement of the local repeater group.  Tonight it has a net at 1900z (8pm UK) on 145.55MHz FM vertical open to all.

Even though we cannot meet in person, we find ways.

CDARC (Cambridge Club) net on GB3PI - Friday 8pm

As CDARC cannot hold regular club nights at the moment, they are moving online. A net is being organised at 8pm Fridays on the repeater GB3PI. This is with the agreement of the Cambridgehire Repeater Group.

Sounds like a very good use of quiet repeaters.

CDARC 2m SSB net 0830z 144.180MHz SSB horizontal

After several Sundays when I simply forgot, this morning I actually remembered!

Even G8OFA in Salisbury was copied, as well as all the others in the net. Sadly, G8OFA could not hear me. Afterwards I realised I was only on 2.5W and I could have used 5W. I am not sure where all the stations were located. Richard, G3TFX, about 200m away, was strong even without the big-wheel omni antenna!

UPDATE  1542z: G8OFA was using 400W to a 7el (on 2m) dual beam yagi. Quite a bit more ERP than me!

CDARC 2m FM Net

This evening at 1900z I came on the 145.550MHz Cambridge Club net. I had a long chat with M0SND (Waterbeach) who gave me a 59+50dB report despite me running QRP to an omni-vertical. Alex is 92 years old  and was a regular on our Monday 2m net. It was good to talk with him again.

At one time (early 1970s) I was on the committee of the Cambridge club. It is some years since I last went to the club. I am not keen on driving in the dark these days.

Cambridge Club Talk - a good turn-out

This evening I gave my talk "VLF Amateur Radio" to the CDARC in Cambridge. The turn-out was excellent, especially considering the very cold weather here at the moment. It was -10deg C coming home in the car.  At the end of the talk there were plenty of interesting questions. It was fun to share my enthusiasm for VLF things with such an appreciative audience. Click on the link if you'd like to see a copy of the slides I used this evening.

VLF Talk - Cambridge Club Feb 10th

On Feb 10th I have been invited to talk to the Cambridge and District Amateur Radio Club on VLF through the ground although I intend to widen the scope to include all aspects of amateur radio communications experiments below 9kHz. In the last year or so this aspect of our hobby has come on leaps and bounds and what was once thought of as impossible being achieved. Surprisingly, this is a very accessible part of the spectrum in which to experiment. If you want to come along and are not a CDARC member I am sure you'd be made welcome by club members.

CamBeam Dec 2010

The latest edition of CamBeam the magazine of the Cambridge and District Amateur Radio Club (CDARC) is now available giving notice of future club activities and projects and of the upcoming AGM.  Currently I am a lapsed member of the club, although back in the early 1970s I was very actively involved when I first came up to Cambridge.

LC Meter - a nice kit

Some months ago I bought a PIC based LC meter kit from the Cambridge Radio Club (CDARC). This was a club project and the unit allows very accurate measurements. The kit had remained unbuilt until today when I decided to build it. I'm impressed: it went together well and worked first time. The quality of the kit is first class with a custom case, silk screened PCB and good instructions on the club website. This little box will measure from low pF and nH right through to uF and mH. I can see it being used almost daily. I believe CDARC is to make these kits available more widely. Go and buy one for £50.
