I tried grid dipping the tank circuit without finding any dip even remotely
close to 75M. I never have any luck with that thing. I tried putting a
2400 ohm resistor across the final plates to ground to simulate plate load
impedance and that gave me resonance somewhere near 3200kcs using an Aut

Can you bring the power supply input voltage up on a variac, Bob? It's
easier to tune the final with lower voltages, AND it'll be

Agreed Mike. I had a power company lineman tell me not to do the

Jim:
get you a sledge hammer and while listening to ur radio smack the pole a
