paws264 said:I also stated, "fully modulated" signal; "100% Modulation" is a reference to the amount of bandwidth that your transmitted signal occupies. This means that if the center frequency is 27.025 Mhz and your transmitted signal is confined to 3 Kc above and below the center frequency (6 Kc total) then, you have 100% modulation. Take up more that 6 Kilo-cycles and you have over "100%" modulation. Modulation is not measured by how far you can deflect a watt-meter.
Can it be filtered to where it will not be such a splatter box?
Remember: GI=GO (Garbage IN equals Garbage OUT), if you have one of those wildly swinging radios then, you are going to get "Splatter".
Back in the "Ol Days" (when that Varmint was built), a radio did 4 watts and, on an Oscilloscope (not a watt-meter) you could see 16 watts out of a fully modulated (100%) signal. I specified "O-Scope" because it has the ability to capture and measure the amplitude of the signal referenced to a certain period of time. A typical watt-meter is just measuring the voltage drop across a resistor which causes a meter movement to deflect. A "typical" watt-meter is not capable of displaying the true power from a RF circuit.

Because the AM detector in your radio deciphers the information from the RF signal based on how and how much the signal varies from a zero reference point, someone figured out that if *I* make the percentage of change from 0 to "whatever" greater, the output will be louder in the receiver. This is achieved by lowering the dead key and making the radio swing higher; the percentage of change just makes those AM detectors go crazy.
Now, to answer your original question: Brewer Labs, the builder of the Varmit series incorperated a low-pass filter in their design, it looks like this:
This filter may or may not still be in your set, pop the hood and take a look but, that filter will not help you against a bad signal in.

Hmmm well I will state the obvious that no one else wants to mention.
So you want to run a grand on CB and not bleed over on other channels ??

That much power....you are going to be a bleeder. Keeping your modulation under control will (help) but shucks....having a KW and running 50% modulation is no fun. Everyone will tell you you're sounding soft and need more. Heck if you want to be loud and clear....and everyone does want to be loud and clear on AM CB....then go ahead and be loud and clear. But you're going to wipe everyone away in the neighborhood on other channels simply due to the sheer force of your huge signal output.
If you don't want to be a big bleeder, then don't run a thousand watts. It's the elephant standing in the room.
Good luck
