Why is it that I can enter a popular cordess phone frequency (46.610 FM) into my R75, yet hear nothing but static? I've done this while at the same time monitoring this frequency with a hand-held scanner, and the scanner picks up traffic quite easily. I don't get it! UJ in AR Maybe either the R75 or the antenna is deaf as a post at 46.610 ? |

I have tried listening, and found that a many-yards-long random wire is just not the right thing at these low-VHF frequencies. See if you can borrow a CB antenna from somewhere, connect that to the R75's coax antenna connector, and see it that isn't better. Or whip up a 10-foot-long folded dipole, with the feedline length an odd multiple of 5 feet. Try habging this vertically. -- R F Wieland Newark, DE 19711-5323 USA 39.68N 75.74W Icom R75 Heathkit GR-81 Inverted-L in the attic Reply to wieland at me dot udel dot edu |

Did you put the R75 in FM mode?

I'm right down the street from one of the University's dorm complexes, when things are right, the air around here is positively "full" of portable phone signals. -- R F Wieland Newark, DE 19711-5323 USA 39.68N 75.74W Icom R75 Heathkit GR-81 Inverted-L in the attic Reply to wieland at me dot udel dot edu |

Thanks to everyone who advised me on this matter. Turns out that Robert F
Wieland had the solution - try another antenna! Can't believe I didn't think of that myself. Anyhow, its nice to know that there are still some helpful folks out there. Heck, even my old arch-nemisis MW Bryant can be helpful every now and then, at least when he can restrain his natural tendencies to stray off onto topical subjects that he obviously knows nothing about. Overall, my faith in this NG has been renewed. UJ in beautiful eastern Arkansas, 'bout an hour or so from Graceland. |
