Whoa! Bill actually went through with this? I never seen this as a production item although the idea of a service bench Analog/Digital voltmeter was something he was interested in doing. The DMM's A/D section was to go to an integrator and drive a meter for peaking or nulling. My understanding was this was going to be a service grade instrument with a 3 1/2 autoranging digit DMM basic. Was this a protoype? Are there any pics?
While we're at it, what ever happened to the watt meter that fed a power pad like a termaline with an attenuated output? Was that talk, or did they ever do anything with that? --- In Repeater-Builder@yahoogroups.com, "Gary Schafer" <gascha...@...> wrote: > > That was an auto ranging voltmeter.
