Hi Alan, Hajo, Markus es all,
tks for the replies.
1. equations ok. there are mny other possibs. but
2. no modulation-bursts from DCF and no other characteristicas. only clear RTTY.
ok, Markus, the big shift on 155kHz is still suspect.
3. DF: 137,4kHz nice zero with the loop to DDH48. 155kHz no DF possib because of
QRM by 152kHz-BC.
4. Hajo, my qth is jo43sv (50km north of Hamburg).
there is a monitoring station from the regulierungsbehörde (german FCC) in my
vicinity (my old employer). but they are technical deaf on lf! so I have got to
see the gents from DDH48. sri no other OM does receive the emissions.
