http://www.geocities.com/kb8qfl/79290.html Techs, Can you tell if this lets the fine clarifier adjust TX? Hopefully just the coarse. That would be OK, I'd rather leave it be if it slides on the fine. Thanks, Randy |

We should get that Triplecguy to try it. Let him be the guinea pig, ;-) If that is the case, it would work like an export radio with fine/coarse clarifier. If so (here we go with the "ifs" again) that would be pretty cool. I do NOT want a TX only clarifier, but coarse tuning, with fine clarifier. |

Anybody? Is it: Coarse = slide for TX and RX; Fine = RX clarifier only? Thanks, Randy |

Okay here goes the DUMB question of the year! What does this mod ACTUALLY do? I know it opens the claifier, but what does that mean (in layman terms)? |

Wild guess - you don't use SSB Terry? In a stock/legal radio the clarifier only adjusts the recieved frequency, but an opened/clipped/cut clarifier adjusts both the transmit and recieved frequency. It's mostly of interest to SSBers because frequency is critical to the tone of the recieved signal and it allows you to be on exactly the same frequency as others so more than two people can have a conversation without adjusting the clarifier for each person. AMers use an opened clarifier to slide in between channels. Years ago radios were allowed to have clarifiers that tracked transmit and recieve, but when the FCC changed the rules - I think it was 1977 - one of the changes was that clarifiers would only track on recieve. In older crystal synthesized radios it was difficult to align each frequency so the clarifier made up for the difference. When PLLs came along it was easy to align the radio so that it was perfectly on frequency, although most aren't even close from the factory. I guess the FCC decided since all of the frequencies of the radio would be off by the same amount it was no longer necessary to allow the clarifier to track on transmit. |
