Yeap, giving up on it. Sideband is by far more civil, however, I do have some rants.
Where Do All The Off Frequency Radios Come From? When the skip is rolling seems like there are more off than on, or is it just me? I hear them down on 27.832 CQ'ing away.
Who is running DTMF tones on 38AM? Last few days constant DTMF at about 7-9 dB, Its killing me on LSB? When I find you Im going to kick you in the PLL's! |

Re Ap....
Why they sound like bees? The reason is that in AM you hear both upper and lower sideband along with a carrier all at the same time.
In sideband mode you hear only one sideband and the other sideband and the carrier are filtered out--sideband has no carriers in its signal. You have to use the clarifier to tune the receiver so as to adjust the receiver to hear the other person in a normal voice. You see no two radios are alike aka components vary in value. So the signals in sideband will be slightly different from radio to radio.
Item two...
Without hearing them, those tones you are hearing may be AM clashing. AM and SSB do not mix. The carrier in AM will create a whine on a single sideband receiver. Perhaps this whine is what you are hearing. |

You cant clarify them in, no matter what I do. I turn the coarse clarifier on the VR9000 till I get them strong, but sometimes its way down 27.832LSB cant hear them on AM or USB. No one around here localy uses sideband so I have no one to verify what I am hearing. In the mobile, the Cobra cant even get them in, its like garbled.
About the DTMF, I work in the communications field. I know DTMF when I hear it. I have heard it the last few days on 38am loud. I think its skip because it fades and disappears in the afternoon.
Thanks

Times change, back in the early 70's everyone was on AM, now it is ssb, back then most all of us had a 23 channel base radio with a stock mike, and a Big Stick antenna, we talked to out friends in our c,b, radio club , we had our own c.b. club channel. and a coffee break once each month with prizes, this is how it was in Buena Park Calif, every evening all would talk back and forth and really have a good time,back then the snobs were on ssb. |

I dont know SSB is a great mode but mixing it and AM ..... too bad that there wan't LEAGAL SSB only channels. |

hmmm..I run ch38 lsb almost exclusively, and don't really have a problem with AM interference. I have noticed a very annoying trend, that is, for folks on LSB getting ticked off because someone is on USB. There are two sidebands for a reason. Part of the problem is receiver design, but the majority is a transmitter fault.
A radio that has not been tweaked to the point of generating lots of unwanted opposite sideband energy will generally not cause a lot of havoc on the opposite side, unless the offended is running crud for a receiver.
I can remember back in the day(late 70's), there were two distinct groups on ch16...the Upper sidebanders, and the Lower sidebanders. One could operate either side and not have a problem. These days, it seems that 90% of the radios are mangled beyond sensible levels in the interest of "loudness" on sideband, and to heck with the sound QUALITY.
I lament the passing of radio for the sake of radio and not for the sake of seeing who has the biggest sounding station. The entire band is turning into a street race mentality. Anybody can buy a big amp, turn the ALC down and get after it. It takes a special operator to patiently wait for an opening then grab that elusive contact, all the while not bothering the heck outta some poor schmuck who is trying to talk to his grandpappy on the other sideband. |

707,
Amen, and Amen again!
A person who understands radio and appreciates a challenge will work radio contacts with skill and patience. To communicate under marginal conditions using legal power levels and depending on the optimal tuning of your transceiver means something.
Any idiot with dollars can buy an dirty amp with enough power to overtalk another idiot who just can't afford that many watts. Further, mis-tuning a radio to "swing" from fractions of a watt deadkey to dozens of watts peak may appear to increase a radio's "loudness," but will result in a tremendous amount of spurious signals, both in band and out. Depending on power/overmodulation is the easy way out.
It's not like I care who does what, as long as it doesn't affect me. Crank up the power! Trash up your modulation! Just don't interfear with my communications! And that's where my complaint comes in: if your radio is so trashy that your USB splatters into the LSB, fix the damn thing!
Best Regards,

When I'm on 11 M I am always on SSB, usually the upper side of 33. It's a fantastic mode and so much more efficient than AM. The more people to abandon AM the better off SSB will be. That will reduce the hetrodyne we here on the band. Now if we could get people to run "legal limit" power stations and not to clip limiters we would have a great band, and when conditions were right, could still work DX stations. 12 watts PEP is more than enough power to make great contacts all over. I do it all the time. One more thing, we need to repect one another and not key up where QSO's are happening. Wishfull thinking I know. Just food for thought. Cheers, SB #106. |

707, you are right. I haven't the time or the money to play keep up in the watt's race. I have only one 150watt amp that was given to me. I use it in the truck. The AM interfernce caused me to loose a perfectly good QSO with a Station from Guatamuala (Spelling?) my first international DX. I have been listening to sideband for over 2 months now, and havent heard a soul locally? AM is king here in Eastern Ky. Thats why I have so many problems with AM bleeding over. All the diffrent Mining operations have seperate home channels and all the truck drivers have cliped mod limiters, which is killin me.
One good note is the DTFM tones are GONE!!!! Atleast today, they have been present almost all the time this week. It was nice to hear clearly on the sideband this morning. |

Why is it the limiter deal that gets the blame all the time? IMHO you can run a radio with the limiters removed (I do) and still sound great. All it takes is some know how on how to set the mike gain and not bleed and still sound like a champ! Just becasue someone removes a limiter desnt necessarily make them ignorant, dumb, or stupid either like some techs like to say! :-) Now you guys can say all you want to about this but im just telling what i have know from my exp on the air. |

I agree HC....no one around here runs limiters any more and most sound very good. Most limiters do a very poor job anyway, even in the high-dollar radios. |

IT ALL STARTED WITH THE POWER MIKE...THEY ALL SOUND LIKE SH-T.... IF YOUR GOING TO TUNE UP A CB
RADIO CUT LIMITERS RUN AMPS AT LEAST USE A STOCK
MIKE...OR AN RK 56... YOU WOULD HAVE A VERY NICE
SOUNDING RIG.IE. GALAXY DX 2547 PEAKED TO THE MAX
22 WATTS PEP SSB..12 WATTS AM.....STOCK MIKE .
SOUNDS LIKE MY KENWOOD IN SSB WITH THE SAME POWER.
I HAVE NOT HAD ONE COMPLAINT AS OF YET.. OH I FOR GOT TO MENTION I LIVE NEXT DOOR TO THE POLICE STATION.. TAKE IT FOR WHAT ITS WORTH.

True, the cut limiter in and of itself isn't always the bad thing. However, I hear a lot of CBers who cut the limiter, then turn everything up to the max.
One fella had things so loud that I could hear the people on the street outside his house talking when he paused. Unfortunately, understanding him was another story.
200 or so percent modulation sounds bad, no matter how you tune the radio up. Keep it reasonable and all will be happy. |

Have to disagree about the power mike....if you run them correctly , they make the radio sound great. If you crank them up all the way, not so good. Stock mic's can't compete with the power mic's if you know what your doing. That's why they have level controls...just don't turn them to the max. |

It wouldn't bother me if everyone ran cut mod limiters, 1000 watt amps, and super charged power mics, but when Im on CH38 and the driver a mile down the road is bleeding over from CH19, its kinda hard to forgive. |

HEY 409
WHATS THE PROPPER WAY TO RUN A POWER MIKE???
FI EVERYTHING IS MAXED OUT ON A CB RADIO NOT 10 METER IT WOULD SELF DESTRUCT IN NO TIME AT ALL?

Many CB radios run "MAXED" out all the time. Not a good thing, since they don't sound good. There no more likely to "self-destruct" than a 10 meter radio. Even those radios won't sound good wide open. As far as bleed-over is concerned, radios running limiters can bleed if there close to the receiving station. I mile is pretty close, not a sure sign of power amd clipped audio. At that range, a good radio can bleed all 40. I have seen this happen with a new radio rite out or the box. I know you say they should not, but the fact is, some do. |

In my 30 plus years of radio, i've owned everything from 39 dollar specials to ham radios that cost several thousand dollars, and almost everyone of them had a better sound with a good power mike. Thats why Icom, Kenwood and all the others sell those pretty 200-300 dollar desk mikes, they are not just for looks, most people know they improve the radio. On the other hand, a good radio can sound terrible with a mike set too high, its like anything else, a person should know or learn how to run their equipment. I hate an over modulated radio as much as anyone, but its not the radio or mike's fault, just someone not taking time to set it up right. scrapiron |

If you want to hear good sounding AM ive heard several on 29.0-29.1 and 7290 the vintage stuff is still alive! |

Like i said i run all my stuff with a limiter remved and ive always sounded good on AM and SSB but i know enough to run my radios the right way too. Thing i do is run the radios mike gain 3/4 of the way open then run the mike itslef about craked open.. |
