Sunday afternoon on the wireless

If you’ve ever needed a good antenna with a quick deploy when you are out portable, you can do a lot worse than using a vertical antenna. My configuration consists of a 9:1 UnUn no grounding spike connected to just over a 10m length of wire.
Ive used a similar deign in the pas that was using just under 10m and it worked really well on 17m. So well in fact that I was able to operate a Japanese station with 30w. (from an FT857D fitted in the car) tho sone is a not quite as good. The wire needs to be shorter, by how much i haven’t worked out yet. But i think that making it shorter by a couple of meters will be a good match for all bands between 40m and 10m.
Anyway here is a video of my exploits. Many thanks for all the stations i spoke with. I had quite a variation on signal reports, some excellent some very poor. And I’m not sure if that was band conditions or down to the antenna performance.

Fun with a Zoom H1

I recently purchased a Zoom H1 for outside audio recording. Ive noticed that the microphone on the
Camcorder is pretty poor when filming in slightly breezy conditions or even when i am not facing the camera.  So to address this a separate Mic / handheld recorder that allows the addition of plug in microphones and being completely separate from the camera is a bonus.

I recorded a film this week (connecting a PL259 to coax) for our intermediate students. I didn’t use the zoom H1, instead as i was sat in front of the camera, i used its internal mic. However when i reviewed what i had recorded, I had a dishwasher, kitten running, dog barking, children playing all over the audio. A perfect time for the zoom !!
I recorded a new track to splice onto the video. Which I’m about 70% happy with. I can assure you its a hard thing to do. Making the speech sound correct, with correct rising inflection its a hard task !
Anyway here are the fruits of my labour. Let me know what you think. Room for improvement i think.

A night out in the big smoke.

A couple of weeks ago both I and my wife were very lucky to sit in on the recording of News Quiz for BBC Radio 4. Its been an ambition of mine for a number of years to visit Old Broadcasting House and to watch a live radio recording in the Radio Theatre.

My host for the evening arranged a tour of the New Broadcasting house news floor, the Radio 4 Studios and most impressively the BBC canteen !

I was amazed how small the Radio 4 studios actually were. Gone of the days where you would have an engineer, Producer and Broadcaster sat in the same room.  But still in one studio there was still a record player and a reel to reel tape machine. Just in case any of the archives were not digitally stored.

The BBC news floor was impressive, many of the TV presenters milling around and a constant hub of activity. For that many people in a single location I was amazed how quiet it actually was.

After a prawn sandwich (my wife had salad – with Chips) we moved onto the Radio Theatre and sat in the front row for the recording of News Quiz. Sandi Toksvig of course was amazing. She started with a great story, and moved onto the recording of the show making it look easy and seamless, the panelists were on top form (Jeremy Hardy, David Mitchell, Elis James and Mark Steel)– and of course Kathy Clugston was superb in reading the news clips. it’s a shame that so much of the evening was edited out, but you have to compress 2 hours into 30 minutes, But the best jokes stayed in.

After the show we nipped back to the green room, and because on this occasion the panelists were cycling for Sport relief they all were pretty knackered, out of breath and in Jeremy Hardy’s case – drinking a cold beer. To be honest I was shattered watching them cycle during the recording.

I must add a special thank you to Jim and Kathy for inviting us as their guests and organising the whole evening. My wife and myself really enjoyed the evening out in London – It was so surreal that it almost seemed normal.

Bath Taps into Science

Bath Taps into Science was hosted in Bath University and Green Park Station during  21st and 23rd March. On Friday Steve (G0FUW), Phil (M0PHI), Russ (M0WYB) and myself set up a stand showcasing the science behind radio. Our audience was 1500 School children who were aged between 9 and 14 years. Reception was well received.

We demonstrated the Oscillation, modulation, reception and transmission elements with small experiments. despite having exploding, messy and amazing things – we grabbed the attention of many teachers and students. Our buildathon demonstration again was really welcomed by STEM co-orindators, and general feedback was excellent.

On Sunday Steve, Phil, Lewis (G4YTN) and Mike(G3VTO) again showcased the science behind radio in Green Square in Bath – this time open to the general public. We had many mums and dads ask us about the buildathon, and even some keen people sign up for some in-class education ready to obtain their Amateur radio license.

Intermediate is go

We have started another intermediate class both in class and distance learning. This course is primarily run on Edmodo. We have run a couple of classes on Edmodo and we think we have the concept correct now. So we have our weekly quizzes set and our 3 week homework assignments all loaded and ready to go.

In class students are also welcomed to join the distance learning students so missing a lesson is no longer such an issue.

Over the coming weeks I will be creating some companion videos showcasing the practical elements of our in lesson activities.

So far we have 5 in class and around 30 distance learning joining us for the next 10 weeks.

On air (ish)

It’s a bit quiet here at the moment, but I have managed to get back on the just lately. A couple of QSOs here and there and I’m quite happy. I did focus most of my attention on 10m where of late the propagation has been stunning.

I haven’t managed the very exotic or rare DX stations simply due to the amount of time I have been on air.

Below is a quick QSO I had with one of the Sochi special event stations. It’s a very quick QSO but you get the idea.

The best KX3 case

When giving the video tour of my latest QRP pack I was asked by a few fellow KX3 owners what case it was that I was using.

Ive created another YouTube clip that shows off the Think Tank Strobe Stuff Pouch. Which was recommend to me by G4ILO on his blog.

If I wasn’t carrying the KX3 in a rucksack I would add some more padding to the case to protect the knobs and corners of the radio.

Anyway I hope the review shows you how the pack fairs up.
