They have at least 6 250 kw transmitters at Sackville, amongst other lesser power units (100 kw). dxAce |

Same results from both. No I did not have the noise blanker on. No Hum on the other stations either. I find it hard to believe I am the only one who thinks their transmitter quality stinks. Reminds me of one of the religious stations on the lower bands. HHHHHUUUUUMMMMMM. Ken KG4BIG |

I did hear some hum Ken, but overall it did not sound too bad at all. And that was on the R8, R8B, two of em at the moment, and the R7. I was listening on 17765 in the previous hour for a bit also and didn't notice anything abnormal. dxAce |

Hum is terrible & audio is distorted. 13.655 mhz is strongest here in KY but that means I hear more Hum. I really enjoy Vinyl Cafe & Qirks / Quarks but I hate the audio . That's odd as they normally sound good here with no hum. Sometimes noise on the AC power can get into the antenna-radio system and mess up certain frequencies. I have had power strips with built in filters that have caused problems instead of making things better. -- Telamon Ventura, California |

The Hum was on all 3 freq. 9.515....13.655....& 17.800. Also I don't hear it on any other stations...well other than the ones I mentioned before. Oh well enough of that I guess. 73 es DX Ken |

I encourage you to look into it a little more. No sense letting something like this spoil your listening. If you have a decent portable radio (on batteries of course) you could check if the hum is heard on the portable. If it is then it's real. If not then is could be an interaction of the AC power, your radio and antenna. I have had this happen only on specific frequencies with the radio plugged into a problem AC power strip filter. -- Telamon Ventura, California |

The usual hum source is nonbypassed diodes in the wall wart, which
provide a nice RF ground when they conduct and none when they don't, thus changing the antenna system 120 times a second when there's an instant that they're all not conducting at once. Even if you ground the radio yourself, they still change the antenna system, though usually it matters less the more grounded the radio is. One test is whether the hum changes if you hold a hand on the radio, improving its RF ground a bit. The fix is a wall wart with bypassed diodes, or NiMH batteries, which are good enough these days so you don't really need the wall wart. Just swap a battery set when needed. -- Ron Hardin On the internet, nobody knows you're a jerk. |
