The "Two Transistor challenge" - taking things a bit too far?

I'm talking 50 yards (at the most) from my house to their nearest tower. My back yard (a pretty standard U.S. city lot from the 60's) directly abuts their transmitter field. Their ground plane wires run right up to the fence. -- ================== Remove the "x" from my email address Jerry, AI0K ================== |

It did take a bit to get the interference cleaned up when I first moved here. But that was 18 years ago, and I haven't had any problems since. -- ================== Remove the "x" from my email address Jerry Stuckle ================== |

My biggest bugbear used to be Radio Moscow bleeding all over the MW AM bands in the 70s on my home made junk pile of a radio. Thankfully those days are past. Nice to see that My junk pile of a radio -components connected by drawing pins (thumb tacks) on a wooden board which may explain the breakthrough - has outlasted Radio Moscow. I still have the radio and it still works. Andy |

t... Sounds like a tuned antenna with a full-wave rectifier could power some QRP projects there..... Urban legend here is of some guy close to Droitwich long wave TX who had several coils wound around the inside wall of his garden shed, and was discovered after complaints of poor signal strength in certain directions, subsequently believe to have been prosecuted over some trumped-up charge. |

I still have the radio and it still works. A constructional method carried on today as the "Manhattan" method, and stick-on isolated isalnds available from the GQRP Club. They also sell a tool to create such islands onto a blank PCB. AIUI, those 10MOhm resistors in your junk box that you are never going to use provide an almost-insulated stand-off. |

I still have the radio and it still works. Andy Yep. And it can be a bit of a hassle on the lower HF bands, but good grounding takes care of most of it. But my dream is to get a few nighttime hours and load the towers on 160. It's on 630Khz, so the antenna farm should load nicely on 1890Khz And since it has a directional signal, I should be able to change the phasing to point it almost anywhere I want -- ================== Remove the "x" from my email address Jerry, AI0K ================== |
