[FoxHunt] PIN diodes anyone?

Barry,

If you are looking for a simple TDOA check out the one on my equipment page.

If you are hunting in the woods ( damp trees) its better to use a beam and
receiver with adjustable gain then a TDOA. Easier to overcome multipath. 

If you are in open dry country (no trees or buildings) a TDOA can give a
very good reading.

Subject: [FoxHunt] PIN diodes anyone?

I am thinking of building a "Double-Duckie" as seen on page 14-17 of the
15th Edition (1988) of the ARRL Antenna Manual.  So far I have been unable
to find a source of the PIN diodes, HP #5082-3077.  Anyone out there build
one of these and have a couple of spares or know of a source?
Or at least a very good substitute?  The handbook seems to prefer the HP
over other choices in the article.  A search of the usual vendors yielded no
luck, no doubt since a lot of diodes have come and gone since 1988.

BTW, I hide a "foxbox" in the north central MA area most weekends, but not
this one as we are all involved in Field Day.  Anyone in the area or passing
through is welcome to seek it out and sign the log.  
Go to:  http://home.comcast.net/~foxbw/  for latest info.  For the next
several weeks it will be hidden in various spots in the Cowdrey Nature
Preserve off Rte 2A in Lunenburg, MA.
Thanks for any help on the diodes,
