Clean Signals from C Class!!!

[BJ radionut]

"Good comparison. It CLEARLY shows the difference between class C and class ab. The class C sounds pinched and distortion is plainly present"

I am with you CK....
The difference would be even more dramatic if the radio's TX audio did not sound like crap to begin with
op:
All the Best

If you believe that I'm certain you too were one of those who headed to the potatoe cellar when Orson Wells broadcasted war of the worlds. That was simply garbage equipment being manipulated to sound as the operator intended, even his voice projection and syllable pronunciation changed dramatically, not to mention how far off frequency it was....by design I'm sure. Sorry try again!

A few times a day on 38LSB I can hear guys using what sounds to me a C biased amp. Sounds just like the viddy shows to my ears. Explains a lot.

A thread to this video should be in the Amplifier forum as a sticky.

Sometimes it's ok to be wrong. Hey, I bet Orson Wells audio wasn't all fuzzy and distorted. If you read back a few posts you can find out why Seriously though IDIeselman, you really should do yourself a favor and Google a little on Class C amplifiers before you post again. Or search this forum. There are a couple good posts about class c amps.

The answer is no! Not discernable to the ear.

Very much so as You can hear on the Mackforce Amp.
Thanks for the Gate Mack.

Bla bla bla, yes we all know the difference between Class A, Class AB1, AB2, and even Class B but, winding up the amp police is much more fun.

Not mine but very cute.

No problem and many details are in the original thread about the recording.

to my ears it was clearly noticeable that the beginning of each word or syllable was cut off in class C mode . turning on the bob85 board fixed that though .

What do your ears tell you about the radio transmissions captured in this recording? Of course, one is mine so I'm very interested in the opinions here.

My take is he is slightly over modulating with the classic Class C pumping which is caused by over driving the output stage, the tx is readable and but no where as nice as your tx.

 

[BOOTY MONSTER]

well , IMO , you were closer to the RX frequency of the magnum that the other guy , or just clarified better , skip played it's part too . but you were clear , no clips and no over modulation that my ears herd . if you were using a class C amp to get to 400 watts it didn't clip like macks did in class C . the other guy wasn't near as clear .

This 2950 (with no weird mods) was driving the X-Force with the Palomar in that video. RCI2950>Palomar 250HD>X-Force 200HD. Sorry for the poor quality photos.

Whether there were harmonics elsewhere I do not know, but that the audio seemed clear only the hearers can determine. The recording is not prejudiced by anyone having set the test up. I was merely working DX with the setup.
