Hi Gernot,
as I am hearing lots of similar signals from a few of the very very big
guns here in Europe contest after contest and no matter if using my
K3's, the KX3, or whatever other rig (i.e. FT-817, TS-590, ...), I'd
suppose this is rather a TX quality problem of them than one with your
receivers. If you would hear it on *every* strong signal than it would
sound like an RX problem but I suppose you also heard all the strong but
clean signals, did you?

Hello everybody,
during the WPX contest I noticed some weird sounds in the K2 when
tuning to strong (>S9+20db) stations.
The sound was distorted, kind of ripple, but it did not sound like
typical ringing.
I also noticed LZ9W booming in on 80m with S9+40db, producing 3 images
in the K2 and the KX3. However, in the K2 the 2 ghost signals were
frequency modulated. How could this happen?
Another big one, LY2W, also produced 3 signals in the KX3 but all the
3 were nice and clean.
I thought these ghost images would depend on the receiver
architecture, or am I wrong here?
Regarding the first observation: Since the K2 is already > 10 years
old, could component aging already play a role. If so, where to look for?
Thanks for any ideas!
