[Hallicrafters] SR-2000 SR-400 Receive schematic

[Jim Liles]

Good afternoon,

The following link is to an SR-2000 schematic that has the receive logic and data paths color coded.  It will work with the SR-400 and SR-400A as well.  

Some parts are different from the SR-400 series but it is 95% useful for those radios.  It will make a quite complex logic scheme simple to diagnose or understand.  The transmit version will follow soon as well as feature circuit schematics.  Please let me know if there is anything you would like added.
