A friend is going to install a potentiometer for varible power on my base and he needs to know if you have to cut the wires off the power pot in the radio and attach them to the new external pot or do you just run a jumper from the pot inside the radio to the new pot?I tried to get an awnser to this in the "Ask the tech" section.I asked but no one awnsered. |

You can substitute the external pot for the internal one, or you can parallel the external pot to the internal pot. With the latter you have the ability to set a minimum power level with the internal pot and with the external you can increase the carrier to whatever level you like. |

Thanks for the info but i read in your profile that you disapprove of ilegal operators so why are you helping me? |

I believe in the Golden Rule so I run my station within the rules. However, I realize that most folks here don't. I'm not dense - I know you want to adjust your power so you can use an amplifer. Hopefully you'll use the control you gain with the variable power to run your amplifier properly and not overdrive it. Keep your limiter working and get it adjusted well and I have no problem with you adding to the din on one frequency.
When I started in radio noone around could answer my questions and I was thoroughly frustrated because I knew I was ignorant and I didn't want to pay some local "tech" to cheat me as I learned. There are way too many "techs" ripping off people that just don't know any better. It took several books and years of reading magazines for me to get up to speed on radio. In doing so I learned that there was a better way to play radio than using amplifiers and echo microphones - it's called SSB! But I digress.
Because of my early frustration I try to help when I feel that I'm not contributing to the chaos that dominates the Citizen's Band. Clipped limiters and splatter are my pet peeve. I don't think installing variable power is that big of a deal. I'd rather have a guy using 2000 watts with no splatter than 1 watt with splatter. At least the guy using 2000 watts is only ruining one frequency while the guy splattering is ruining many - and for no good reason. Plus, you can use variable power to lower your output just the same as you can to increase your output. I'm in favor of folks using only enough power to make the contact and no more - that's just good radioing. |

Well sorry to disapoint you but i do bleed over.I operate on ch 4 and all the other guys near me say i bleed all the way from below 1 up to about 20. |

I see. Does it bother you that you're interfering with other frequencies when you don't have to? |

if it's from a clipped limiter, you should've had it put on a switch. if it's because the guys near you are, like, next door, then probably not a lot can be done about it. when my neighbor's sister shows up in her mini-van & calls him on her stock, untouched mini-cobra from his driveway, she'll splatter 80 channels. not much you can do when the other radio is less then 100' away. other then hope it ain't runnin' kilowatts! |

Strong signal interference isn't splatter. Technically it's intermodulation caused by bad design or too much signal pushing the receiver into non-linear action. If you've ever listened to CB with a communications receiver that has selectable filters it's very easy to tell when someone is really overmodulating. On a typical CB you can tell by reducing the RF gain until the signal is about 1/2 scale, and if it still happens then it's probably true splatter.
Better radios have automatic gain circuitry to deal with strong signals. That's why the MB8719 dual conversion 7.8MHz SSB chassis is so popular. There are things that can be done to improve even that fine chassis and others. Adding additional filters like the Channel Guard filters or replacing the stock filters with sharper units can greatly increase the adjacent channel rejection. |

Yeah most of the guys who say i'm bleeding are a mile or less from me. |

I ALSO OWN A 696F SSB,MY QUESTION IS NOT HOW TO GET VARIABLE CONTROL BUT THIS RADIO HAS NO "SWING" TO IT...ALL REPORTS SAYS THE RADIO HAS GREAT AUDIO. USING AN IMAX 2000,RG-8U COAX,MY EXT. METER AND 55' TO THE BASE OF ANTENNA. HOW DO I GET MORE SWING IN IT? |
