The valve circuit below appears to be a type of four stage amplifier.
Can anyone tell me the approximate gain and bandwidth? The 60" antenna would tend to indicate 197MHz full wave, but is this (or quarter wave) a valid assumption considering the components used?
Does the circuit do anything other than amplify, e.g. oscillate due to high gain, modulate? I ask because it is built into a transmitter.
Thanks for any insights.
