[Heathkit] HW-16 Warble

[Mark K3MSB]

Good Morning.

I should mentioned in my initial post that I monitored the voltage at “C”
with both a scope (through a divider network) as well as with at VTVM.   I
observed no correlation with voltage variations (very, very small) with the
warble.

A few times the voltage dropped by 5 volts or so (could have been power
line fluctuation) but this did not cause the warble.

I did not monitor the heater voltage as some of you have suggested.   I
should have thought of that as I’ve run into heater related issues in the
past.
