It was the Decca system that employed "slaves" - Red, Green and Purple.  Decca Navigator and then Racal-Decca had a nice little business going until GPS came along and spoiled their business case in the 1990s :-(

I think the Loran-C “slave“ stations were officially called “secondaries“, possibly for political correctness.

Hi Stefan !

no, i was just using the master/slave scheme from LORAN systems as an

analogy. As everybody on this reflector is familiar with it ;-)

I guess the "master station " should be selected from a view of

practicality. It needs a somewhat geographically centered position in EU

plus some technical advancedness.

Looks to me as if u are in the bowl :-)

And yes, the northamericanos are doing this activity thing quite nicely,

an european counterpart event would be a timely thing i guess.

The kite antenna is intriguing but it is not a normal installation and

requires lots of time and weather cooperation. I´d reserve that for TA

attempts. Just too much effort for a regular thing to happen.

The signals are so loud in EU on MF, even verticals of 10m height only

produce enormous signals. I guess a wide audience can play that game.

On the other hand . TGIF !!!!
