There is absolutely NO corelation between SSB and NPC-RC. The NPC-RC modification If NOT meant to supress the carrier which is done in SSB. It is also NOT meant to get rid of one of the sidebands such as is also done in SSB. In An SSB transmitter, the sidebands are generated by a balanced...

I don't see ANYTHING that is being done that will inhance the signal. The best that I can see, there is no positive peak inhancement. It is apparant that the negative peak is somewhat compressed due to it's brightness but it does no good to compress the negative peak while still limiting the...

I don't remember if I have put this link on this forum or not but if not here goes: NPC-RC Negative Peak Compression-Reduced Carrier This is from a very old websigte of mine that is defunct so don't expect the site to work very well. If I have already posted this link, forgive me but...

The best thing to do, until I get the NPC-RC website going is to google the radio that you are interested in doing the mod to. I haven't done one for the Cobra or any of the transformer modulated rigs. That is way I am talking about doing the kit for. A kit to convert a transformer modulated...

This thread! Wow! Believe it or not, I took the time tonight to read this entire thread which started almost 6 years ago. It is absolutely incredible how many, apparently--very knowledgeble cb'ers AND extremely well informed Ham Radio operaters ever got that well informed. The reason I...

Interestingly enough, I HAD already answered the question that I thought I had not answered. LOL! However, I did not answer loosecanon's question about the 148. I have always done that mod by using the exponiential curve caused by the capacitance being increased instead of the diode curve...

I have been gone from the internet for quite a few months. I Now am back in Arkansas and have had a new shop going for almost 3 months. I JUST read the last few posts. I am startled at the response buy such seasoned ham radio operators. Such as "static carrier level" I guess very few have...

That is NOT what is happening! If the negative peaks were not compressed and you modulate the positive peak as much as possible--but still below the saturation level--the negative peak would severly clip. The NPC components, normally just a single diode and a resistor, causes the gain of the...

I am in California now and will be going to San Diego to do some design work and I will be leaving with two very good Spec/an's and two very nice scopes, and ALSO some 3 and 4 hundred amp power supplys. Once I get set up in my new CB shop In Arkansas, I will "put my money where my mouth is" so...

if exceeding a modulation index of 1 is the only objective that can easily be done by simply expanding the peak-to-carrier ratio of the resultant output signal. no negative peak compression is required and waveform symmetry is maintained without being concerned with clipping of the negative...

While I have seen the formula you posted, I think, I do not know what all it is talking about so I Googled it with: dB = 10 LOG(1 + M)2 as applied to amplitude modulation. I didn't do an hour search--only about 15 minutes. So, why don't you explain what everything in the formula means and...

I am not going to get into a hot and heavy debate with you but Even if that formula may be called a properly modulated am signal. it is not the only proper way to do it. It depends on what you are trying to accomplish with what you are doing. The NPC-RC is far from much to do about nothing...

Did you not Understand 15minigrass? The NPC-RC DOES NOT cause ill effects. For one thing the picture that the guy did at Best is NOT trashed on the negative peaks. That picture is a beautiful example of EXACTLY what the compressed Negative peak should look like except it is compressed too...

I never did do what I had planned to do so I will do it now. That is, rebuttel the following post. I have mingled my statements after each quote.

Regulated bias and output filter improvement are already on the way. That is one of the first things that I will be working on for My Personal designs and I believe I will have quite a lot of the power of persuasion in other designs. About the Bird slug; Yeah, I wasn't trying to describe the...

Thanks for your cheer for me being here! I don't know about YOUR varmint. I do remember that I received 3 amplifiers that I still owe for to someone. I know what the other 2 are and would recognize their handle if it were still the same. What was your handle then. You have to realize that...

'ok doc ,this being said why are we concerned what a machine says our audio sounds like?we should be concerned what our ears tell us ,not some machine.we hear with our ears ,not machines . this could get beat down to death but you ham guys just cant get over it .i dont see any cb`ers jumping...

I have to address one more thing! The idea that "if the mod were a good thing, it would come built that way from the manufacture". That is such a lame idea that it almost does not deserve being addressed. You have been in the cb world long enough to know that the FCC does not allow the...

Bill Good Was a personal friend of mine. He once told me that I was the only person that he knew of that he sent customers to. I am the one that sold him the Viper Antennas after he quit buying them from MJ products. I am the one that made them. And BTW, Bill was the only one I would send...
