Thanx for the help. :D

I have two Cobra 25's I have done the mosfet mod to one and the swing mod to the other and with both of them the lights will dim when talking, is there any way to fix this?, and does it even make a difference? :confused1: Thanks, H

I have the schematics if this would help?

Curious to know if anyone has any info for ugrading finals and or swing mods for this radio, board is a EPT012910Z simmilar to the Ranger TR 127. :bdh: Thanx, Hog.

Yeah I like the recieve on the Cobras better than the Galaxy's and such I think thats the direction I'm gonna go now. Now I just need to get it hooked up to a meter and see where it's at.

Got it fixed thanx for the reply 9C1Driver, I'm ashamed to say I had one leg of the 520 soldered to the wrong pad, Hog.

Thanx, yeah I did the whole Remove R38, R40, C45 replace r40 with EN-1230 then add 68pF capacitor across C42 thing,but I must have missed something or messed something up because I wound up with a low dead key and no swing. Better luck next time. :oops:

Hey ya'll looking for a little help please, I did the 520 upgrade to my Cobra 25 but now I have a low dead key and it doesn't swing like it used to. I might add I also did the Super Swing mod prior and it had a nice swing untill I did the final upgrade,did I miss something? :headbang Thanx...

Yes, I'm sorry not much of a electronis guy I just like to tinker.:oops:

Got it! Got it they're the same as the new model connex and general lee's and such. Open the top and remove the four diode cluster and Viola!

First of all new to the forum so howdy ya'll, I'm looking for info on the channel mod for my new radio and also any info you could give me on upping the modulation. Thanx,:thumbup1:
