Guess I have been lucky. For the past year or so I have been using a Daiwa 2
position coax switch between my K2 and TS-950SDX to the amp. While listening
on the 950 through the coax switch I listen to the K2 on the low bands using
my receive antennas. If I want to use the K2 to transmit I use the coax
switch.
So far no problems.

PS - All set up here at WP2Z for this weekend using my K2.

My measurements on ham grade coax switches show 40 dB or less isolation
between positions.

IN FACT, 60 dB is high even for a commercial grade switch.  The simple types
from MFJ that are wires to a multiposition wafer switch do not shield quite
long wire runs from the adjacent connectors.  Those are the long rectangular
boxes with UHF jacks all in one row.
