Dave and all:

After much frustration using Daiwa coax switches (either fail or develop 
high insertion loss):

I searched for SPDT coax relays but found some Dow-Key 2-pos coax 
switches for $49.91 from RF Parts.  They are rated for 1-kw at 2.5 GHz 
(way over what I will run thru them: 130w on 2m and 60w on 70cm.

Bought three to replace the three Daiwa that are bad:
S1 - 2m output of IC9700: 2m amp input or 10-GHz transverter input
S2 - UHF output of IC9700: to 432 yagi or vertical
S3 - VHF output of 2m amp to 144 yagis or vertical

My 4-position coax switch (S4) will resume use as a band switch: 
144-432-900-1296.  Common LMR-400 coax is run to the outside equip box 
where relays separate connections by band.

This will aid switching antennas during the net
