Dunno about the model, but I was hanging out in the wheel house of one of the
Monterey dive boats a few years ago while we were coming back from a couple
of dives off Big Sur. It's grey day, but the marine layer was up off the water and
visibility was maybe four miles. At about Cypress Pt. the radar starts showing a
BIG target dead ahead. a couple of miles.

Now, A) we don't get big targets in Monterey very often, and esp not in water that
shallow, and B) we can't see any big targets visually. A couple of small boats, and the
Pt. Pinos buoy a couple of miles out, but nothing near that big. When the
range gets down to about a half mile, Capt. Phil starts looking kinda nervous. Then
the marine layer lifts a bit, and: Goodyear Blimp. ;-)

There were some strange diodes in the klystron tune regulated voltage source
that were no longer available (this in about maybe 1978). Dumb thing would
drift out of front panel tuning range periodically. Could bring it right
back with chassis pot, of course, but owner frowned on that and I never did
get paid! Don't blame him a bit.

The KRA124/248/448 didn't have a Klystron for an LO, but was the first
of the Second Generation Radars, and used an XBand Gun Diode Osc. As
I recall Furuno last used a 2K25 Klystron in the KRA 121 Series Radars
which was before Northen picked up the Furuno Dealership. Don
Hollingsworth Sr. at G & L Marine was the KRA-121 expert and has always
been the "Go To Guy" for Marine Radar Technical Information, even when
he was the Raytheon Marine Tech (Ray 1500/1700/1900) for the NorthWest,
and worked for U.G. Allen.

Man that does date me, in the North Pacific Marine Electronic Community.
