Fellow,

Do you have a name?

Awesome work you are doing on the filters.

Good luck and stay with it.

I Think getting 50 db  on the open bench is about as good as you can go 
in open free space like you are doing.

I is likely a good enough test for what we need
 to know about doing the repair / replacements /re stuffing.

thank you for all the work you are putting into this venture.
