Pfffffftttt!! Johnson KW matchbox directional coupler diodes?

[Dan]

Greetings Gang:
I had some lightning in the area last week and was fortunate enough to be
missed for the most part. The antenna switch was in the grounded position
etc. etc.

For some reason, maybe unrelated, the SWR/relative power meter is no longer
with us. I suspect the diodes or caps in the coupler first. I can't find my
manual.

Will 1N34s work in there? How about 1N914s? Which is the preferred diode?

Has anyone ever used some sort of knife switch in a 600ohm balanced line?

Thanks
Dan
