[TenTec] OMNI VI illness

[Dave Edwards]

Bob...is the low pass filter board such that the relays can be removed 
with the board in the radio...or does the low pass filter board have to 
come out?  Am I correct in that EITHER K4 or K5 could be bad causing 
both bands to go out?   So, if I replaced them both...I'd solve the 
problem...or take one out, then I can measure them individually...one 
out, and one in the radio...hoping that I removed the bad one. Is that 
about right??
....Dave
