I hold the callsign G8LYB. I
am not very active at the moment but I am often listening to the local 70cm
repeater GB3ME.
I enjoy design and
construction. Sometimes I even actually finish a project.
My local club is the Rugby Amateur Transmitting Society I can often be
found there on a Tuesday evening. Visitors are always welcome.

On the Continent the ASCOM SE550 is often known as a “Condor 3000”.
The EPROM and original software used to reprogram the units supplied by the Rugby Amateur Transmitting Society can be found at:

There is a lot of useful information on this site, but it is in Dutch!
An alternative set of software (not free!) with additional functionality can be found at:

Once again this page is in Dutch!
