Chinese frequency counter module
#2

I tied mine to the cathode of the 76 osc tube in the 660 and used it to set the lo. worked fine from bc to 18.460. This model only goes down to 1mc, which is ok for bc osc 550+460kc. Also didn't notice any noise generated by it. Don't know what it uses for a time base.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
