Bias Is Really Just B(ia)S

[SuperLid]

Someone I know, sent this link to me. Quite interesting.....On one hand, there's a guy in Idaho, that struggle to make up five dollar words, in a great attempt to sound intelligent. On the other, this guy in TN, seems to make an extra effort, to sound as stupid as he possibly can.

I think I have heard it all now. Yep...

When I was first playing CB radio many many years ago I had a texas star modulator, no bias, single transistor.
Started getting into SSB , delay is easy, bigger cap, boom,no chattering.
My little brother could 100% tell me when I was using the modulator, so I had him run it in his car, yep crunchy distorted signals on SSB regardless of the delay.
That's as good as the guys that tells newbies to run yur mike gain up, the background noise holds the relay open.......

lmfao That's some funny shit,
or it would be if he was not building amps for people & posting shit like this on youtube,

Anybody that cant hear class C vs AB on SSB has faulty ears.

I think it might have something to do with the distance of the DX.

Several years ago, somewhere on this site, someone was talking about this, but with AM. They were saying that the scratchy overmodulation seems to go away with distance.

I run a Cobra 148 as a dedicated station monitor, with headphones and no antenna. I can tell that the comp style amplifiers I have need more bias. I think.

Listening to my Stryker 955 on an Xforce 4 pill, I can hear the scratch on SSB. DX reports say it sounds great, and this is from people I know would tell me if it didn't. The radio by it self sounds just as clear as AM.

My Icom 718 with power turned down into a Carl built 4 pill is the same way. DX reports are great, Station monitor says otherwise.

The only setup that sounds correct with an amp is my President Madison with a Texas Star DX500 putting out about 350w.

This has always made me wonder if I should try to make my other setups sound like the Madison and DX500? But if it sounds good on the far end, do I really need to?

Anyone else use a separate radio with headphones to monitor?

If all is adjusted properly there is nothing to monitor.

If you saw what he builds, you would fully understand, how stupid this guy truly is.

Calling your amps "Donkey Stomper" says it all,

Listening from this side of the pond the quality standards of tx audio on 27.385LSB has improved markedly over the last few years,

In the past .385 had lots of people using scratchy class C amps or CB's with locked clarifiers (off frequency) & carrier set point misaligned for the radio's ssb filter,

I think more people now use HF sets & sound ok,

on 27.555 it was the Italians that often used class C cracklebox amps but that has mostly gone out of fashion too.
