Steve,
I am not sure it is contact bounce. I look would at grounding or other issues
that would conduct transients of the relay coils into the RF stream.

My frist thought is to clean the contacts ( there open frame relays)
For changing the relays Direct replacement difficult . The Co that makes
them produces them in limited runs for Amerirtron

Subject: Topband: Relay bounce
I am using an Ameritron RCS-4 antenna switch to select between beverage
antennas. Recently, it has developed a bad case of relay bounce causing an
S9 spike every time I switch between antennas. Any suggestions on how to
improve this ? Since it's only used for RX antenna selection, I'm amenable
to replacing the relays with something else, although I have had issues
before with other relays due to no current going through the contacts.
Thanks and 73,
Steve, N2IC
