[Lf] BBC 198kHz information

[Steve Dove]

Greetings,

I don't know if anyone else noticed how loud the Euro Longwave
broadcasters were earlier this weekend.  It provided this recovering
Brit an opportunity to listen to BBC Radio 4 'armchair copy';  the World
Service is nice but second-hand via Antigua or Sackville is no
substitute for straight-in-the-vein domestic programming from those big
sticks next to the M5 near Brum.

Coincidentally, a few days ago I was indulging an office clean-up (done
every decade or so, whether it needs it or not) and came across an
ancient proceedings book of an IBC conference;  one of the papers
concerned the then recent (early eighties) refit of the Droitwich LW
station by Marconi.

In addition to some insights to the (again, then) revolutionary
PWM-modulated transmitters and detail sketches of the
valves-to-combiner-to antenna matching arrangements, there is a little
drawing of the changes made to the antenna and a comparison graph of the
R/X before and after.

Ever sensitive to copyright issues, I nevertheless don't feel that
anyone's interests are going to be dented or that Legs Luigi will be
after my hide, or worse,  if anyone on the list here is sufficiently
interested in a copy.  Macaroni have been out of the big transmitter
business for a while now, anyway.

Interestingly, given the Beeb's 25-year re-equip cycle, they're probably
starting to figure out what to do next time round . . .

        Cheers,

                Steve        W3EEE  /  G3YDV
