when listening to the hf bands, i hear strange speech from some people. when they talk, all i hear is the voice of alice the goon or charlie brown's teacher. other people, the people that are part of the conversation with these people sound normal; but no matter how much i adjust the voice tone settings on my radio, some peoples' voices cannot be understood. Why is this so?:smoker:
What make / model / vintage radio are you using?
yaesu ft767gx, with a 260 ft dipole, connected to a buried 200 ft rg58 coax lead directly to a mfj941e tuner, to the radio. antenna is 30 feet high, with dipole ends facing north south. i cAN HERE responses to alice the goon, but alice only i can't zero in on... is he on the dipole's nodes side?
Are you on the correct sideband?
160-75-40 use LSB by convention; above 30M uses USB.
Some people sound strange no matter the offset. :smoker:
like i said, ya'll, the only person that i can't hear is alice the goon. i can hear people reply to his conversations with him, not just can't hear him.... and not only that, i can hear his voice noise from 1885 all the way through 1910, on all of the bands.
Turn off the rig's noise blanker and turn on the attenuator. Does the Goon still come through?
Yes to the noise blanker check. I have two adjustable noise blanker buttons.
One is aggressive, strong in band stations rip it up. Useful to dig out the weak.
Other is for busy band, LOUD signals. With strong S/N ratio, meh little help.
Another issue (maybe mentioned) is the width of your RX passband.
2.7 KHz from the manual, but a LOT run 3KHz wide or wider.
It's a jungle out there. Many EQ stupidly with poor articulation.
hey ganstas, this is major tom to ground control, noise blank was off already and have now activated the ATT button..... so now, it's just "a wait and see," until when alice the goon will meander into the communication zone ......
special thanks before hand, ya'll

Must be a localized phenomenon.
If across an entire section of a band, receiver de-sense or spurious mixing with another nearby strong signal. Enough to drive the front end into non-linearity.Quote:

Is there a wire beam pointed your way?Quote:

ok, ya'll........... what is a wire beam. is this like one of saddle stretchers they tried to get me with, when i worked at the racetrack in new orleans...... i know we are strange down here, but snipe hunting sounds a little fishy, ..... hunting with a bat and a bag?
hey, man where's the bartender? i need a ta-kill-ya
Oh boy, you're all dancing around the most obvious answer that came to me the moment I read the first post, Alice is not on the same frequency as the other stations. There are numerous ways this can happen, too many for here when you being tech minded know them. I had a rig with 3 sections, HF, 2M, and 70cM all with a common TX MO that was slightly off frequency from the RX and digital readout. The higher it went in frequency the farther off it went, I received stations OK but one 2M SSB op told me I was transmitting some KHz up the band, FM is forgiving, AM is forgiving, SSB is not.
warren, i gotta' tell ya' man, for a grumpy ol' bastid, you just might have somethin. that would explain why only alice is affected, and no one else. alice ain't been around lately, but everyone else is coming through just fine.

What about SSB (or AM) with simultaneous FM due to an oscillator being modulated at the same time? Crap power supply OR poor old power supply unable to keep up with the current demand and losing it's stability?
