[GreenKeys] RTTY Journal help

[Ken LoCasale]

Gang,

I am trying to read an article from the RTTY Journal Dec. 1978, AFSK 
Generator about p.16, (attached). The generator uses an EXAR 2206 chip. 
On the hand drawn schematic, I cannot read the pinouts, especially the 
lower part of the chip around C3. Can't read the numbers or if there are 
connections or pass throughs. On the schematic some obvious crossovers 
are dotted for connections, some obvious connections are not dotted.  
Right around C3 is the issue. Is anyone familiar with this circuit or 
have a better copy?

73,

ken - wa4mnt
