[nabentre] Digital Recorder

Mon Sep 12 15:56:33 UTC 2011

Dear Brian,

Picky, picky, picky.
The one I have picks up just fine.
If there is a hum in the line, there is a hum in the line.
As I under stand it, he is just after the ability to record an incoming call 
on a cheap digital recorder.
That is what I answered to.
If he wants to get a perfect, clear recording, and can spend the money for 
the equipment than he is asking the wrong people.  He needs to talk to an 
audio engineer.
I do have some experience in this area as an engineer for General Electric, 
Nuclear Energy Division.
I worked with a number of ex-nuclear sub sailors and we were developing a 
acoustic leak detection system for use on steam generators and heat 
exchangers for the Clinch River Fast Breeder Reactor Program.
This type of reactor uses sodium as a coolant instead of water.  Sodium and 
water don't get along and any leaks in the system can be explosive. 
Therefore, we had to be able to detect micro leaks early and plug them off 
safely.  We were good enough that we could find leaks as small as 3 microns 
inside a heat exchanger some 85 feet long
and 12 feet in diameter with over 200 individual tubes.  We could even 
detect rats walking on and around the heat exchangers and hear workers 
working on and around them too.  Leaks had their own signature and we 
learned to screen out the other sounds.
