Series Pass Modulator for D.I.Y. Hi-Fi & Asymmetry

[groundwire]

Like "HAM" bands?
OK, since you are the authority on the subject matter, I'll just quit listening to my lying ears and concede that it's completely false because you said so. Thanks for being the arbitrator of all things audio. I'm not sure the world could exist without you, thanks.

hahaha, what a sad and immature display of your ability to hold a conversation. im just relaying what countless studies have proven to be fact! if doing all that audio rack gear stuff is how you play cb radio then go for it. everyone do whatever they want that gives them hobby enjoyment, thats what its all about. but i wont bow down to your false logic and information. with a name like "doctor audio" you would think you knew a little more about the subject besides wrong information. see you on the air, im the guy running 5kc wide stepping all over ya!

Can we all agree that sometimes we disagree; no need for a p*ssing match here gentlemen.

@LeapFrog - Haven't heard from you in a while - hope things are well with you!

In case anyone really hasn't noticed - (Redundant?) most of the discussion happens to be around the bandwidth - wanted just to point out several radios that are now AM only, but don't use "Mod Transformers" anymore.

President ANDY II -

President Bill -

Wheres' the Transformer?

Ok, it's time to gulp a couple of Aspirin and realize the pain is here to stay.

What Leapfrog is doing or trying to show you - is already done and being produced to REPLACE that which we took for granted. Being the Reactance Modulator aspect, the Mod Transformer did - only you need to remove the spike diode and get the full benefit of PHASE modulation which is the equivalent of FM.

So, to complain of even mention the issue of Bandwidth - the above makes the argument moot - bandwidth or not - it's just not going to stop the reign of terror the manufacturers are placing, shoving or dumping onto our shores.

This tells me that the older chassis may be outdated but become more valuable because of the jump over to AM Regulation skips the PHASE process.

Just stuff to think about...

I have a NOS Uniden 78XL. I plan on doing the Gold Finger cap changes and setting it up for an Electret Condenser Mic.

Probably a 1.5 watt to 2 watt dead key and a 2 pill amp behind it. On 99.9 of radio's it will sound 10-8 and Great! Most radio's will not pick up what Prime Minister is putting down! On the other hand they will hear what I am putting down! LOL!

It does not have to sound the best of the best it just has to sound better than 99.9% of radio's to kick ass, leave a foot print and take names! LOL

It is one thing to maximize the performance of a very average radio it is another thing to try to re-invent a radio. If you need a better platform than just start with a better platform.

Cheer's to making a good radio sound it's best on a budget!

P.S. People will think it is the best damn radio they have ever heard!

....wait until you hear my 60's era Neumman condenser thru a Neve 1073 pre and into an UA 1176 limiter back into a customized Demeter tube DI to bring back to line level and into audio circuit of my chromed cobra 19 using direct injection. hell yea it rocks!

Would you happen to know the location inside the radio where the hifi direct inject was added ? Please thank you

 

[Squints]

Which capacitor do I remove to add the hi fi audio direct injection in a cobra 19 dx .?

Would you happen to know the location inside the radio where the hifi direct inject was added ? Please thank you

Um a post or two past the one you quoted, Rick let us know that he was joking and that post about his Cobra 19 wasn't serious.............
Also, the post is four years old and the OP (who was joking anyways) hasn't been here for a couple of years!

Adding bass response will make the modulation limiter a necessity. The audio harmonics from overdriven bass tones will cover up the parts of your voice that make it understandable. Sounding like AM broadcasters is okay, but you'll find that their modulation is strictly limited to 125 percent positive, and 100 percent negative audio peaks. You won't sound like them unless you include that feature.
