Bruce and Skipp and group,

 

This discussion made me look in the file cabinet and I found the entire
package (instruction manuals, schematics, etc.) for my Sinadder CML-1.  The
manual is actually for the Linear-5 meter, with an inserted Addendum for the
CML-1.  I also have a few advertisement sheets and an interesting
application note that shows how to make a SINAD measurement.

 

I am too busy over the holiday, but in early December will make a scan for
the Repeater Builder library.  I will mention this to Eric and he might have
a better way to get this out.

 

Jim

El gusto es mio Bruce... I'm a big fan of Helper Instruments 
and have a small bit of history regarding the Company. When 
the founder passed, his daughter tried to keep the ship floating 
but the original innovation of Helper Products was gone. 

Eventually... Zetron bought the rights to produce some Helper 
Products, but those were discontinued when the Radio Service 
and Repair Market all but dried up. You might check the Zetron 
site or drop their technical support a note asking if they might 
have the manual/diagram for that instrument. 

I might have the manual to the plain-jane sinad meter... the 
operation is the same but again the C Msg filter is a nice 
option to have if you need it/one. 

cheers, 
skipp

Thanks Skipp, for starting me off in the right direction.
I've found some interesting reading. My meter arrived and I'm starting to
get used to it. Nothing in that specific Model (CML-1) yet, but hopefully I
will find that also.
73,
Bruce
