[ARC5] Programmable Oscillators - Redux

[David Stinson]

OK hold on there a minute-  these ideas jus' keeps cooking.

I turned everything off and went inside to have dinner with 
my sweetie babies.  Then went back out and..... it didn't work.

I looked at the drive from the little CMOS oscillators.
Still at 2 P-T-P on the Osc. cathode.  
Xtals give 3 Volts.  I guess this just 
isn't quite enough to be reliable.
So I decided to swipe the 4:1 UNUN from the TTL Osc.
and try again.  If you remember, the CMOS oscillators won't 
drive the UNUN primary directly- it's a DC thing- so 
I put another blocking cap on the output.  Just happened to
grab 680 pFd because it was laying on the bench.
With the voltage step-up of the UNUN, the cathode is
up to 3 V P-T-P and the receiver is back alive.
Going to wind a 9:1 tomorrow after work and see how that does.
