I'm not sure about that one................I do have the two CD rom set with
the Drake manuals, so I will check them later on. They used to use a
Motorola TO-92 package type in the "7" series.
Anyway, you can't go wrong with the 1N5767....................they were used
in the KWM380, although there was an upgrade that some of the folks over
there used to do with some Unitrode PIN diodes, although I don't recall the
part#

That is a strong possibility. Once we get ahead on the big project, we

will
work more on the radio / accessory details, including the Sync Detector.


That's great news. It would be neat to have an external sync' detector
for my old 'boatanchors' or even a car radio.

BTW- I'm looking for some PIN diodes for my R8B. It looks like some of
them in the front-end bandpass filters might have been damaged or

become
leaky. This also happened to my SW8 several years ago while it was

still
under warranty. Drake did the repair. What do you suggest for a good
PIN?

The HP 1N5767s are a good bet. What is desirable for this application is

a
diode with a long minority carrier lifetime.
The 1N5767 meets this requirement with its 1.5uSec lifetime. They are
available off the shelf from Newark Electronics. Digi-Key or Mouser may

also
have them.


Thanks. I'll check them out. Do you know what PIN Drake used in the SW8
and R8?
