Hi Stefan, LF group,
attached, there is another successful reception of ur signal at 136.172
khz using my ferrite rod antenna.
It seems that today evening you decided to slow down things by a factor
of 1.5 so instead of qrss60 i saw
DK7FC letters being tx'ed in qrss90.
Taking into account the fact that the receiving conditions are far from
being optimal
( indoor, possibly some plasma tv sets in adjacent apartments and
likely other qrm sources)
the ferrite rod antenna, indeed, may be a good choice for field, /p
receiving purposes.
Also, due to its directional nature such a rod could be used as an
auxiliary antenna in a noise canceller setup
btw, the ferrite rod along with veeery ugly construction of preamp can
be seen here:

i am still thinking of building some sort of support stand etc...
