* Amateur Radio on Anglesey *


Anglesey is a very radio active area! The Island boasts an excellent club, the Dragon Amateur radio club, which meets on the first and third Mondays of each month at the Ebenezer Hall, Llanfair P.G. The current membership is around 40 members and we provide training for each level of the amateur radio licence.
The club programme may be viewed on the club website.

On behalf of the club, I give tuition for all grades of the UK licence. My RSGB registration is FIA/GD/MW0SEC. Classes are undertaken at my home. Also see: the RSGB web site

My own location near the village of Carmel, is ideal from the radio point of view, being some 350 feet above sea level, one of the highest points on the island, which permits a clear line in all directions.

My shack details are as follows (In 2004):
The rig is an Alinco DX77, which I normally work (100W) into wire dipoles for 160, 80 and 40M. A recently completed tower project now gives me an Adex tribander on a 45' steel tower with Create rotator. On occasion I use a long wire, in conjunction with an MFJ 949E matching unit. Also available for receiving is an Eddystone radio 1830 rx. and an AR3000A scanner. I now use a computer logging system. The logging programme is home-brewed. This is necessary since I run Sun computers using a version of Unix (Solaris 7) and all the popular logging programmes require the dreaded PC/Microsoft combination (ugh).

I started on the air as MW3CVQ, and my current callsign is MW0SEC.

Have a look inside the shack:

The shack is built on a mezzanine floor inside one of the two barns at the QTH, which is a 17th. century farm.
The barn badly required re-slating and while I was at it, I decided to build a dividing wall and floor for the shack. Now fully insulated, it remains cosy even during the worst of the winter.
The complete roof required around 3000 slates, 10"x20" and was completed within one summer (phew!)


Latest update at August 2005:
Now equipped with Ranger 811K linear (Built from the kit), which helps with difficult conditions. The tribander has been replaced in favour of a 20M telex hi-gain 3el. Yagi for optimum results on that band. It gets me nicely to VK and seems to be much more resistant to the winds of Anglesey.

Even later update at March 2007:
The Ranger has now been replaced by a home-designed linear based upon a GS35B and I have also built an audio processor. Both of these can be seen in the 19" rack in the pictures below. The item between the linear & it's PSU is a 4M rig made by Tait. Beam is now a 17M Yagi.


Projects:
HERE is a presentation I gave to the club on a build of a direct digital synthesis signal generator which includes the circuits. The software listing for it may be found HERE.

This shows the finished generator. Note that the tuning increment may be changed
without losing the currently selected frequency. I did not include much filtering of the output,
since harmonics can be useful in a signal generator. Setting the generator to the 70 mc/s
region for example,gives useful output on 2nd. harmonic for checking the 2M band,
although at this range,
the amplitude can not be relied upon.

















73's!
