Re: [Amps] Gassy Tubes/Technology Museum looking for artifacts

["Pat Barthelow" <aa6eg@hotmail.com>]

Hi Carl, and group:

One, the 807, comes in a  metal envelope, liquid cooled configuration...(:>) 
  ....rumored to  add DBs to signal reports, and bring in larger crowds to 
antenna parties.

A lot of the old ham vernacular and culture is fading into the ether these 
days...
Same phenomenon, that whistling CQ in a crowd of techhie strangers, usually, 
  no longer  gets the knowing smiles of the ham operators among them....   
(;>)

http://www.smecc.org   has a lot of nice technology history bytes, and is 
looking for more..

73,  Pat
