[TenTec] RF Speech Processor "TX IMD"

[Al Gulseth]

Well said Bob. The only thing I'd note is that in the broadcast industry "back 
then" (I was a small market AM chief and TV operating and maintenance 
engineer for a while) "good engineering practice" to me implied making sure a 
surprise inspection by the "Commission" didn't turn up anything amiss. 
Needless to say, that's not generally a factor in defining "good amateur 
practice" unless it's a really blatant violation.
