I forgot to also mention if the Alpha Delta has just 30 dB of isolation
then you are putting 100 mW into your front end. That could be enough to
blow something.
I don't like the idea of a sensitive front end designed to pick up
microwatts being subjected to power levels on the order of a fraction of
a watt. True a good design shouldn't be a problem, but who knows.
I don't understand what the surge suppressor does any that Yaesu claims
failed. Sounds like the way it surpresses RF surges is by failing!
I guess if no one else has an idea of what the part does, ask the Techs
at Yaesu. If they don't know, try to find someone at Yaesu that does.
Someone should be able to explain it. It would be interesting to know as
I also have an FT-1000D.
