[GreenKeys] Yaesu YR-901

[Larry W7JYJ]

Greenkeyers:

Anybody out there got a circuit schematic drawing for the Yaesu YR-901
CW/RTTY reader?  Or of a source for one?  Its an early 1980's RTTY/CW TU
that will drive a 20-ma current loop for TTYs and also has video output for a 
CRT display.  The YR-901 manual has the circuit diagram for the optional 
AFSK unit, a parts list for everything, but no circuit schematic for the 
FSK unit, main board and PS unit.  Perhaps these were in a loose leaf 
insert.  I've not been able to find these on the web, from FoxTango, etc. 
I'll be checking with Yaesu next week. 

Thanks, Larry W7JYJ
