I seen the article but it is talking about retro fitting the new 24 pin into a older 22 pin circuit. I did check and voltages are the same on pin 16 which would be old pin 14 so might try it this weekend.

Welp figured out my noise it was the ground on echo board put the ground on the mic ground noise is gone thanks for the help guys

Upon checking with multimeter pin 16 has the same voltage readings as my 22 pin chip so one would assume it would be the same guess nothing left to do but try it out see I'll keep you posted. Thanks for the help guys

So based on that tsb it would attach to pin 16 but without knowing for sure makes me Leary although this ic would work in older radio what about a new one that has came factory with it? Guess I would need to check with multi meter see which one was floating as said earlier

Looks like this. Neither of my other radios have one like it

It boosts recieve on distant station but you have to be careful as a local will overload you. You install a 22k-220k resistor inline with it. The lower the value the more it is boosted. As I said this pll has 12pins on each side only says cobra 29 series on it I like the mod. It doesn't boost...

Has anyone seen a 24pin pll chip in a cobra 29 nw ltd 2015 model. I was going to do the pin 14 pll to + c12 mod but didn't know how that would work out with 24pin pll The older ones just have 22pin or ones I've seen anyway

This is true. I need to send it off somewhere have It aligned especially now got everything fixed up in it. I just don't have that equipment.

Will do. If I'm able to get it out I'd like to worth trying one more spot anyway. I really appreciate the help man with both amps I'll let you know how it works out. Now if my receive parts will get here the 3 schottky diodes and tr7 transistor. Besides the c12 to pin 14 is there anything else...

Like I say the buzz is audible but not overly loud audio comes through loud and clear without the buzzing. With It off no buzz with it on slight buzz when keyed

But after having one nw that doesnt work have to say I am a fan of a working nightwatch no matter how long it lasts haha

Hadn't tidied up my wires yet and don't have the cap on but if you look you can see my shield ground on the transformer

Not sure which one it was but attached the echo sheild to mic ground and rfx sheilds to transformer added a 4700uf filter cap to the input and all is happy now. Get a slight buzz on transmit with unit on but can deal with that I suppose.

My point would be Friday at work me and a buddy were talking to a guy a good ways away guessing 45-55mi but not sure as the crow flys put meter on his radio .5w my peaked 29 doing 9w on older ratshack meter could hear both of us. I'm running wilson 1000 with 62.5in hes got k40 I believe not 100%...

None taken I can see exactly what you mean. I was kind of new to the hobby see it cheap power got sucked in..... we'll call it a $25 lesson but I figure everything is worth a shot. But on a power note 1. What would be the distance difference between say stock 5w avg 15-20pep And 1969 supertune...
