Vintage video evening

Ever heard of Hackaday.com?  Nope I hadn’t either so last night was ‘special’ 😉

Paul, M0ZMB, showed some decidedly old video’s from the website.  The first couple were about Philips A63-11X cathode ray tube manufacture. These were followed by a short video about Bone records and then a fascinating video entitled ‘The craft of the Cooper’.  Although very, very grainy it was delightful to see real craftsmen at work.  The final four videos where about the making of porcelain insulators, electric 100w/120v light bulbs, the joining of cable using lead wiping and transitioning telephone exchanges.   For the enjoyment of members who couldn’t attend or who just have the urge to watch again I’ve placed some of them below.

Others can be found at Hackaday.  Search for ‘retrotectacular’

Coax notch filters by G0GDU

A problem we have experienced on several field days is that transmitted RF from a transmitter overpowers a nearby receiver despite it being on a different HF band or even on a more distant part of the spectrum.

Band pass filters are the usual approach to solving such an issue.  However, another approach is to place a wide notch filter over the entire interfering transmission.  This is the approach described by John Crowder, G0GDU in this article passed to me by Rex G4RAE last Wednesday.

Hosting migration

I’ve had a busy afternoon migrating this website from a server of my own to a hosting service funded by the club.  Its taken a few hours as there where a few problems but it now seems to be working albeit a little more slowly. 🙂  If you do notice anything strange please drop me an email.

As part of the migration we can now have club email addresses.  I have created role based ones for the committee (e.g. chairman @ tsgarc.uk etc) [remove the spaces] and can do so for any member requiring a club email address.  If you would like one, please let me know.

The Icom IC-7300

There is loads of noise about the IC-7300 at the moment in Radcom, QST and other magazines.  So I felt we should do our bit too!  Here are a couple of video reviews of the radio.

The first is by AmateurLogic and chaired by George Thomas of Ham Nation and Ray Novak from Icom America.

Should the club get one of these?  Let me know 😉

The second video is by Bob McCreadie (G0FGX) of TX Factor fame as he talks with Icom UK to give an overview of the radio.

Antenna Horizon

Have you ever wondered what it would be like to sit at your antenna and see what it ‘sees’?  Well, this evening I attached a camera to my antenna and shot the following short video as the mast was raised and rotated.

The video starts with the antenna pointing at 45 degrees.  Once elevated its rotated to the following directions where it stops momentarily: North, West, South, then back around to East, South, back to North then to 45 Degrees before the mst is finally lowered again.

What this little experiment shows is that the horizon looks pretty flat in all directions – no big hills evident.  It also gives a good feel for how well the antenna clears the surrounding houses.

RSGB Convention

RSGB Convention

The RSGB Convention takes place in Milton Keynes over the weekend of 8th and 9th October.

Not to be confused with a rally, the convention has lots of lectures on topics related to Amateur radio including DXpeditions and a construction competition.

Video’s of lectures, talks and events from previous years can mainly be found on Youtube or on the RSGB (Members only section) website where there  is a Navassa Island video.

Hope to see you there,

Thornbury Carnival 2016

Jane talking outside the TSGARC tent

The 2nd of July was the date of the Thornbury Carnival and what a glorious day it was.  Hot and sunny.  Thanks to those who helped with the organisation, who provided equipment, who got equipment to/from the site and to those that manned our tent through the long day.

We where allocated a prominent position slightly down the hill from the entrance/exit so there were lots of people passing and quite a few stopped by to see us.  Although the pitch was in a good position for passing traffic, it was in a very noisy position, not far from a music stage and had a children’s inflatable play ‘thing’ next door.  The latter had an acoustically noisy generator running the whole day which, at times, made hearing the radio’s hard.

Mark and DerekAll-in tho, it was a good day.  We handed-out many flyer’s advertising the club and had at least one person promise to come to the club.  Jane and Sue did an excellent job at arresting our local Police, telling them about Amateur radio and getting a promise of a lecture….

The real test of success will be how many potential members come and see us over the next few weeks.  But even if its none, I believe it a worthwhile exercise as it helped communicate Amateur radio to the general public, raise our profile within the community and has most likely secured us a talk.

Garry, G7NVZLashing a pole to an in-situ climbing frame and another to my truck we managed to get a dipole for 20m operational and made several contacts across Europe. We also had a short ‘white stick’ antenna for 2m and 70cms which allowed us to communicate with members not attending the site during the day.  Peter assembled 10 x SDR radio kits to sell to interested visitors and sold 5, including 1 to Mark ;-).

Thanks again folks,

MoTA – Cancelled

The TSGARC has, unfortunately, had to withdraw from attending the Yate Heritage Centre this weekend as part of Museums on the Air due to difficulties agreeing terms for our use of the lawn next to the centre.

Thank you to everyone who has put effort into making this, so nearly, happen.

Event organisation

Whether it be a talk by a member or a larger event such as a field weekend we all enjoy events. Events are core to our club; they bring us together and allow us to share idea’s and information with others. An active, vibrant club is a rewarding environment for existing members and its attractive to potential members.

Its a core responsibility of every member to participate in events – after all, the club is its members and its members are the club. We are one and the same.
Participation is helping with an event in some way. That might be taking some photo’s and writing a few words for our website, it might be helping to transport equipment, it might be arranging for a speaker to come and give us a talk. Participation by members is the life-blood of the club.

So if you have an idea for an event please talk it over with other members and together we can make it happen. Whether you are involved in turning your idea into an event really depends on your wishes, its size and complexity. But here at the TSGARC we encourage all members to be involved with making events happen.

Further information about events and their organisation may be found by following the ‘Event organisation’ link to our website.
