[Repeater-Builder] Re: Helper Instruments Sinadder Model CML-1
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 [pasted text] 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 skipp025 wrote: C Weighting Filter, do a google search to find: http://en.wikipedia.org/wiki/Weighting_filter It's an audio filter option... nice to have if you need it. s. ve1ii bhar...@... wrote: Hi, could anyone give me some information on what the C MSG feature is for on a Sinadder Model CML-1.

I think it is basically a Sinadder 3 but am not sure of any differences in it. 73, Bruce, VE1II
RE: [Repeater-Builder] Re: Helper Instruments Sinadder Model CML-1
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.

See... no good deed goes unpunished... thank you very much for your kind offer Jim. I'd be excited to obtain the information for myself. Makes it hard to be rotten to people... sometimes. s. wa6vpl wa6...@... wrote: 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.
