Uniden 525 VHF and general question
"Wayne.B" wrote in message
... Agreed but you could have a bad connection which is heating up under load. BINGO! They use one of those crap, 'slow burn' fuses. They heat up and the extra impedance reduces the voltage. Get rid of it and put a higher amperage rated, fast burn fuse in - end of problem. Wilbur Hubbard |

Wilbur, you need to stick to stuff you know about.... as Peter Bennett pointed out, if the volume at the receiver dropped, but the background noise didn't change, then the problem is in the Modulating Deviation, not the Power Output.... This is FM not AM or SSB.... In FM, once you exceed 12 db of Receiver Quieting the Background Noise, changes are hardly perceptible, and in FM, the volume produced in the receiver is directly proportional to the Modulation Deviation of the Transmitter, until it exceeds the bandwidth of the Receiver. -- Bruce in alaska add path after fast to reply |

Skippy said the volume of his 'transmission' as heard by other listeners in nearby boats decreased noticeably after about a minute. So the problem is with Skippy's transmitter and not his receiver. If the fuse heats up and the voltage drops and the "low voltage" indicator flashes in the readout as Skippy indicated then that should tell you something. Duh! Wilbur Hubbard |

Wilbur Hubbard Actually it is YOU, Wilbur, who can't read, or does NOT understand the technology that you are talking about. The Deviation of the Modulator in Skip's Transmitter is EXACTLY what we are DISCUSSING and the VOLUME of Skips signal has absolutely NOTHING TO DO with the Power OUT of his Transmitter, but everything to do with the Modulation Deviation of his Transmitter.... This is why a One WAtt Handheld sounds just as loud, in a receiver, as a 25 watt radio, when both signals are above the 12db Quieting Threshold of that receiver.... You just show your ignorance, when you spout off about things you have no Clue about.... -- Bruce in alaska add path after fast to reply |

I happen to own one of those crap radios myself and I have discovered all their foibles and failings. You are just operating on theory and your theory is little more than an uninformed guess. So take a hike. When you get some experience with this particular radio perhaps you can return then. Besides, anybody living in Alaska where he gets is ass frozen off most of the year can't be too bright in the first place. Wilbur Hubbard |

Besides, anybody living in Alaska where he gets is ass frozen off most of the year can't be too bright in the first place. No reason to drag Sarah Palin into a radio discussion. You should be ashamed of yourself. --Vic |
