The relays used are 3P2T, with one pole used for locking out the other port 
from
that antenna.

I find that over time, that pole sometimes fails to make contact on the unused
port, thus preventing the port other from selecting it.

Even after cleaning the relay contacts & giving the relay frames a little 
tweak,
it's still intermittent here & the solution has been to leave the cover 
off, so that
I can either apply a little pressure to complete the connection, or merely
wiggle the relay slightly to achieve the same - perhaps what the brake on the
rotator is doing for Blake.
