to RE-INVENT the Hmm, always this wheel: may be it's not necessary to re-invent it but it is fun and as far as I know not forbidden. I'm sure if it had only just been invented it WOULD be forbidden
Decca masts - latest situation. Agreement with Racal obtained. Schedule of available stations upcoming. RSGB notified; support of HF Cttee promised. Applications for possible NOV's in process. Contro

There's a pic of the Decca mast the DMG are using this weekend at: http://www.blacksheep.org/lf/decmast.jpg and a pic of the old Decca ATU coils at: http://www.blacksheep.org/lf/coils.jpg There had t
Gee, thanks guys - it was nothing! But I really have to congratulate those who did the hard work of hauling kit back and forth in the rain and then putting up with blinding flashes and bangs as they
A bit more about the Decca mast: It's basically a 325 ft (100m) self-supporting tapering tower (see Mike Dennisons' and my own pix). When it was built in 1946 it was hoped one Decca chain might cover

(a) If both aerials are vertically polarised only then there shouldn't be any difference between their radiated fields if they're radiating the same power because both are electrically very small. Th

David, Your query: I've been looking for a high stability source to act as a timebase for a frequency counter and for a PLL reference. I notice that the older Magellan GPS300 is available at $ 99. Do

Hi Markus, The Alpha operators probably haven't paid their electricity bill. There were three Russian high-ups at a conference I went to recently who had some say in operating that system and they sa
I understand there are now several reflector members who now own ex-Decca Transmitters. Is anyone interested in a temporary 'Decca Users group' for the purposes of exchanging information on modifyin

Hello gang, Since our professional controversialist ('3KEV) has raised the big/small antenna discussion again, and I'm fed up playing Scrabble, here's a few points he might like to ponder on while he
For some reason this didn't seem to make it onto the reflector first time round so here goes again: Recent discussions on "CW" and "Morse" have brought up some interesting points. Does a mode that is
