Patrick:
PIN diodes don't protect the front end - they are normally used to
switch preselecter filters above medium wave as their losses are too
high at MW. If you're having MW sensitivity problems, it is very likely
to be something else.

I'll be using the SPR4 for a while as I sent my R8 back to Drake for
service as the sensitivity has dropped. Probably the PIN diodes
protecting the front end are bad. I have used the R8 thousands of hours
for the past 19 years, it needs a tune up.
