That's what I did, 10nF added to the loop- var cap setup, and now I see
that RMC INfo on 216 comes in with sig 9... (without loop: about 1).
Strange thing is that with var cap + 10nF the loop only tunes between
say 207 and 225 khz, while on AM (without the 10nF), it tunes 1 MHz wide
..
Of course, now I can add more turns to the loop.
The loop is 2 x 3 meter of PVC tube, bended in a circle.
There are now 3 turns. Guess ... how many turns to have the LW
153-279khz ???

(when the box is closed, you can put a radio on it, nicely positioned
inside the loop)

some 15 turns... on a 2m diam loop ...
I know about the computer flat cable trick...
