Typically on activity nights we use just one HF antenna – such as multi-band vertical or wire dipole and we manage to work a dozen stations on HF. However, this week we had two portable antennas at our club base at Pinetrees, giving us the opportunity to work two bands – 20m and 6m.
The 6 metre antenna, brought in by Paul 2E0PMV, was a commercially made Moxon loop supported on a Maplin extendible mast. Six was reported to be open throughout the day so we were keen to check out the E skip to see if conditions had changed. Having hooked up the PSU to the Kenwood TS 590S, by 8pm we were ready to put G8SRC on air.
Rob, M0GKG took to the mike first and comfortably worked a couple of stations in Eastern Europe. Then, Tony G4LDL followed suit, working some very strong signals from Spain. By nine o’clock, conditions declined we switched the rig to ANT2 and gave 20m a try using a homebrew portable 20m rotary dipole made by Ed M0OSM.
This very professionally built antenna was similar in appearance to the Buddipole. Mounted on an 8M painting pole, the antenna itself was made from two portable short verticals, screwed into a threaded dipole centre. This time, Rob worked several European stations with ease – Norway, Spain and Latvia all reported 59. And Phil M0PBZ couldn”t resist trying the M0OSM-antenna on the CW section of 20 metres. On 14048, 4Z4DX in Israel came in too strong to ignore and Rolf gave us a 599 report. Not bad for such a compact antenna. So all in all, we had a very active activity night.
For anyone wishing to explore Amateur radio, visitors are most welcome. Even in challenging weather conditions, we always aim to operate our club station on activity nights usually using SSB and CW modes. If you would like to come along to see Amateur Radio in action, contact us at M0PBZ@sdarc.net. And if you are a licenced Amateur, or an inactive licensee it would be great to see you.
The SDARC AGM for 2013 will be held on May 23rd 2013.
To speed up entries on the night it would be great if you could fill in the entry form(s) ahead of time. This document can be downloaded from this post.
Construction Competition Entry Form
Dear Club Member,
The constructional contest rules state that for an item to be accepted as an entry, it must have been built in the last two years.
This year, as we did last year, to increase the number of entries to the contest, we are relaxing the rules to allow each member to enter ONE item which may have been built at anytime; the item must not have been entered for a previous contest.
Sunday 10th February 2013

Dear Club Member,
This is a reminder that the SDARC annual construction contest will be held on the 28th February 2013. So, you have ten weeks left to build that kit or to finish off that unfinished project. The rules of the competition are the same as last year, with a total of nine prizes.
A copy of the rules is attached.
It’s been usual for people who wish to become active on the microwave bands to build their own equipment from scratch or from a kit, to modify commercial equipment, or if they have deep enough pockets, to buy completed equipment from the handful of specialist manufacturers who produce equipment for the amateur microwave bands.
Most modern components are only available in SMD packages. For most people, building equipment using modern surface-mount components isn’t easy, and hand-soldering doesn’t lead to great reliability, but boards built using automated assembly techniques are extremely reliable. It’s for that reason that a range of equipment will only be available as assembled and tested units via GW4DGU.
Chris Bartram, GW4DGU, will be remembered by many as the founder of muTek limited and the designer of much of the still highly-regarded range of VHF/UHF equipment manufactured by the Company.
Modules for 10GHz are available from Chris via his website http://www.chris-bartram.co.uk/products.html
Just came accross this site (via RadCom) and thought I would share it with you all. They have an amazing number of antenna related hardware which is ideal for mounting and building antennas. They even sell aluminium in enough sizes to slide inside each other. Each length is 6′ and they also have a kit of 11 (inc clamps) to build a 60′ vertical.
They have a good collection vertical antennas you can buy, even a mono band 80m!
It is worth a look.
If you have received your new call book (or CD for the ‘modern’ men!) you may find an interesting oddity in it. Club callsigns are shown with the secondary identifier, so OUR call is shown as GE8SRC.
This was brought about as the extract of the content from the Ofcom database that is passed to RSGB for callbook / yearbook use was sent with the secondary identifier included for clubs.
It appears that though ‘spotted’ by RSGB, they are not permitted to change the data to extract the “E” for Data Protection reasons. Since the data isn’t “wrong” (just excessive to the norm) Ofcom are satisfied with their data.
This anomaly shouldn’t cause too many problems… we can ignore the “E” on the air and on QSL cards (or use it for extra ‘interest value’ when chasing DX !!).
Looking up a club call in the book will show the call in the normal sequence, but looking it up on the CD ( ..and maybe later but not yet on QRZ.com) will require a search for GE8SRC or it won’t find the entry.
QRZ have provided a statement…
For now, QRZ will list the call signs as we have been and will thus, not be affected by the E extension.
Thanks to Den, M0ACM for the researching this news.
