Cobra 25 Tune-up:
Spread coil L9 slightly.
While transmitting a "Heeeeeeeeeeeeeeeeeeeeeello" into a wattmeter hooked to a dummy load or an antenna (preferrably a dummy load), adjust L18, L17, L14, and L10 for peak wattage output. You may have to adjust these several times before you get them all peaked properly.
You can also clip the limiter diode, but that mod I prefer not to do because it is unnecessary and causes overmodulation and distorted speech if the radio isn't adjusted exactly right.
Sorry, I like CLEAN audio, not loud booming audio that you can't understand!
