(WTB/LFS) (EU) 900 MHz cavity duplexer/filter
« on: September 17, 2016, 07:40:17 am »
Hello!

I am looking for a 900-ish MHz cavity duplexer/filter in the EU so I can modify it for use in the Scotty spectrum analyzer, similar to what was done in the attached video.

I couldn't find anything on eBay in Germany, tons of Celwave stuff in the US though.

Does anyone here have something like this or knows where to get these?

Thanks,
galvanix

There's a guy on Scotty's yahoo group that sells pre-built cavity filters made for the analyzer.  I don't know how much he charges but I think they are reasonable and plated as an option.

I have a 4-tube that I built and Jim Hontoria, another member of the yahoo group, and I designed and built a two-cavity filter that performed well also.  Send me a PM if that person on the yahoo group isn't building them anymore.

Thanks for the hint cncjerry!
I didn't know that there were people specifically selling these cavity filters.

The reason that I am reluctant about building it myself are because I just don't have the right tools on hand at the moment.

I will contact you, if I can't reach the other person ;)
