Subject: HP 5360 "interpolator" info wanted
To: ham-homebrew@ucsd.edu
I am trying to keep a couple of HP 5360 computing counters operating for
Ham Radio uses but a common problem over time seems to be the
"interpolator" module for which the technical manual gives no information.
I suspect 20 years ago the technology was proprietary and the info was not
publicized. Does anyone have a schematic or other info on this module?
Any help would be greatly appreciated.

Hi All
The Vismueller book does actully have some pratical sections, as opposed to most
of my engineering texts. Glad we have Zverev already.
Don't forget the interlibrary loan option. I have yet to find a book I couldn't
get for a couple of weeks. Usually at little or no charge.
Ask at the reference desk in your local library.

We used a ground plane instead of a point. It is the usual practice for
RF circuits. Double sided PCB's were used in our design. The ground
plane was created by copper pour in the final stage of the layout. We
always routed the PCB manually by the RF engineers. This approach works
very well.

Where can I get a copy of this "PADS" program? It sounds interesting!

I keep looking at that Uniden 2600 with the blown final transistor...
..and I keep thinking: "How tough would it be to convert this muther
to 6 meters?" Well...let's see..a new display table in the uP's rom
so it would read "50-54" instead of "26-30", a new LO, a new mixer,
maybe keep the IF's as is...modify the mixers a bit, a new final..
..some osc in the receiver?...Hmmm??
On the other hand, why can't Uniden BUILD a 6m version of this rig??
(It cant be any more expensive than the 10m ones, 2510, 2600, 2950 etc)
..as an aside, is anyone from Uniden on the net? Are you listening? ;-)
It just KILLS me that Yaesu wants >$450 for their 6m all-mode!
