These definetly are from a Sinclair hybird-ring duplexer. The coaxial style notch tuning cap attached to the tee was salvaged from the hybird ring phasing harness. I believe these are single mode cavities. I have two of them tuned as notches to keep a local paging TX from interfering with a 2-meter repeater. I can come up with the Sinclair model number of the duplxer tomorrow if that would help.  73,

Fellows,
 
I bought these cans at Dayton last year. I have no information on them. The interconnecting harness is butchered pretty badly, so I'm not sure of the correct lengths. I'm hoping that someone can recognize these and has some documentation and / or a set that we can use as a pattern.
 
I think these are Sinclair, but I'm not sure. Kevin and I have put them on the tracking generator and have been able to get LPHR response out of them, but not HPLR. I think this is due to not having the correct cable lengths.
 
Thanks in advance for any info and to you dial-up subscribers, sorry for sending pictures you may not need.
