[Elecraft] Strange K2 Behaviour - KAT100 Antenna Isolation

[S55M]

Hello!

There will always be a cross-talk between antenna ports on KAT100.
If u put on unused antenna port some 50 ohm dummy the crosstalk will be
lower.
I did measure crosstalk between ports on my KAT100 now aprox results are:

28Mhz 35 dB with unterminated ANT 2 port and around 40dB with terminated...

I suppose the crosstalk on lower bands is better!
