Talk to Dick Bob.  You need to add some capacitance either in series or
shunt (I don't remember which) to tune out the inductance inherent in those
relays at 50 MHz.  I don't remember the details now but Dick can give you
the info.

Does anyone coming to the mountain for the contest have an MFJ swr meter 
that reads out the complex impedance?  If so, bring it along as I'd like 
to sweep the stack switch with it to see what the characteristics are.

It is working fine and has some swr, but not enough to bother us or the 
radios.  Just want to check it out and see what's what!  Probably is 
just the fact that they are open frame relays at 6m.  I have seen times 
a cap needs to be added to help the situation with open frame relays on 6m.


Thanks, Bob
