That's what I did first but they do at least pretend they have no info left
on this older model duplexer. But the typical Sinclair instruction leaflet
(some are available for other models on repeater-builder and on Sinclair's
website) doesn't reveal such info anyway.
Duplexer manufacturers in general do guard everything as jealously as they
can.

Martin,
The best place to get that information is from the company that built it.
Contact Sinclair Technologies at 800-263-3275.

Does anyone have technical info (i.e. tech drawings) or inside pics of
these
duplexers? I wonder how they do the shortening as there can't be a 1/4
wave
resonator for 2m inside this 19 box...
