mopar, I apologize, you did say books and not the net. I also did not mean to offend anyone, at all. Sorry for the frustration Ron.

Wait, I just reread your post. I got it. You said biasing has to do with when it is "on" and you are exactly right although i have NEVER heard someone put it that way. What I think you are not understanding is that the amp is "on" when it is replicating information (modulating,) during the time...

Sorry mopar The one and only thing I know for sure in that entire post, and have know for 15 years is that modulation is the percentage of information reproduced expressed in degrees of the sign wave. I understand you have taught yourself mostly on the net, do me a favor and google...

You are correct, of course, but I think I have found the awnser, can someone tell me if I'm wrong? Modulation is the percentage of the information waveform that the amplifier recreates. A=360 degrees or 100%. In the typr of radios this forum is concerned with, we are usually talking class...

Wow learned alot tonight. Thanks guys. Anybody mind if I sum up? Basically, big hammer trimmed his coax to recieve 50 Ohms at his desired frequency. The antennae and the van and the coax all together gave him 50 ohms and that is what the radio wanted to see. So Master Chief is right...

Lords I just went through this thread again and you are right, I am guilty of thread jacking. Please accept my apology. If you would like I will post my last question as a new topic. Sorry Ron

QRN you are absolutly correct and if FT1(SS) George (ma A school instructor,) were here right now I would be doing pushups until I cried for typing such a silly statement. Mopar One of theese days I'm going to understand this rf vs modulation thing. From my basic understanding I agree with...

I truly hope your joshing Doc. Ron

Loose cannon, somehow I missed thanking you for your post. I do apreciate it, I understand how transformers work I am just trying to piece together all they do in AM amplifiers. So far I have identified theese roles. Voltage transformation (obviously) Isolation from free radical RF (very...

Hey Lords, can you explain that to me? I know that to double sound it needs to be increased by 3db. If you run 2 10 inch speakers each recieveng 100 watts, they will sound twice as loud and measure 3db louder than one of those speakers @100 watts, that is physics and reality. I have measured it...

Thanks, I think I've settled on a radio. I like what I read about the TR 966. The price seems right and the features I want are there. I know the two radios (TR-966 and Cobra 29P) don't have much in common but to be honest, I really like the case on both of them. Neither of them look like the...

Looks like a 29 with a different face plate. Any other differences? The one I'm looking at was made in 1987. What do you think? Thanks Ron

WOW!! I just sat down in the USS Seawolf (SSN 21)s radio room and got a crash course in AM radio design from two 20+ year radio chiefs including one who worked in the maintenance facility building and repairing amplifiers for about 6 years! (for those of you who don't know the Seawolf is a...

Mopar Just read the thread about the amp in the Sony enclosure with the extra thick solder. Your last post was right on and really cool. You sound like a level headed individual. and Mountaneer is a NUB junior officer it looks like. His piss and vinegar will cool down after getting hir...

OK, thanks. I apreciate all your help. Ron

http://www.phy.davidson.edu/instrumentation/NEETS.htm This is all the modules. The table you are looking for is in one of them, they are all excelent and I can't recomend them enough. Sorry, it's been about 8 years since I've completed them. Ron

mopar2ya Thanks, I caught that part, I may be making an ass out of myself but by "stuff" I thought he ment "interference," or "damn free redical RF" as my old Bull Nuke (who was a nuklear trained ET,) used to call it. If that's what "stuff" is, then my idea will still work. Thanks again Ron

Sorry Lords, I totally lost you in the jargon. I'll try to go line by line and explain what I think you are saying. "swing is when you DK(keyup low 3/4-1 watt) and swing full (maximum)power output while modulating(talking into the mic)" OK, so this means that swing is just how much more...

Thanks doc. I understand how transformers work, I just wasn't sure if they had another purpose in amplifiers. I always guessed they assisted in building RF, shows what I know. Great, then if all they are for is to adjust voltage, any voltage regulator should work. I think I'm starting to...

Great, I get to bug you guys with more questions. Can someone please tell me what on eatrh swing is. I understand what carrier power is, and I believe swing is how you measure PEP? Not exactly sure, but if swing is PEP then I'm al screwed up because yesterday I thought swing was modulation...
