Six million people worldwide enjoy Amateur Radio as a hobby. Most Amateur Radio operators (Hams) are involved in Global
communication; a great way to develops better understanding of geography, languages and cultures. Licenses are granted by
Governments after the operator has passed the appropriate examinations to ensure they have the skills to transmit relatively
high power signals on frequency bands across the spectrum, with minimal risk of interference to others. Many Hams enjoy the
achievement of using equipment they have designed or built themselves - aerials, transmitters, receivers and test equipment.
Amateur Radio is often used to provide emergency communications, eg. the Indian Ocean Tsunami and New Orleans floods of
recent years. Click here for information from the Radio Society of Great Britain.
And the Lord spoke...but now with radio! (Menorca - Monte Toro convent)
My blood ran cold when I switched my FT-990 on and found the 'lights on but no-one at home'! Luckily it is now working again
after I accidently connected -12v to +5v outputs from the voltage regulator. The suspicion is that a semi-dry joint on the 5v
regulator was made again by me overloading it!
I have declared the Sutton DSB HF transceiver finally complete! The latest modification has been
an LED bargraph audio derived relative s-meter. Now I can think about starting a new construction project - probably the
Single Sideband 'Minster' transceiver, a Walford Electronics design soon to be available in kit form.
Just before Christmas, I upgraded my AKD-2001 2m FM rig to 12.5kHz channel seperation.
Garex
have made an upgrade kit available which was very straight forward as most of the hard work is done
by the replacement PIC processor which they provide. Since then I have added a CTCSS encoder - for details, click

Early in the New Year I built a L-Match ATU
from mostly 'retro' and scrap components. The
hardware side of the project was the most difficult - drilling
and cutting all the metalwork. My son cut the front and back panels thankfully. See pic -->
Over the Christmas break I built the
Cumbria Designs Frequency Counter kit.
Its main purpose being to sniff whatever RF I'm transmitting! The counter is working well.
