[WARC] Manufacturers of Duplexers on 146.640 Repeater Site?

[Len Litvan]

Can anyone tell me who the manufacturers are for the two duplexers at 
the 146.640 site--the 2 meter duplexer and the 440 duplexer?  Thanks.

If anyone has recommendations about a source for professional servicing 
and tuning of duplexers, please pass this information on to me also.  I 
am requesting this information as part of the club project to cost out a 
good renovation of the equipment at this site.

Thanks & 73,
