The modulation limiter is d12 and d13.If you intend on cutting it to give more modulation don't because all you greate is a radio that splashes every channel.

Working on a 25ltd classic that was wired backwards and wouldn't power up. I changed diode and it lives again. 10 watts output no modulation.


10 watts is illegal. Modulation circuits didn't fare so well. A lot of components fry when you reverse polarity.

How do I adjust modulation on cobra 25 wx nw st?


The Modulation adjustment is VR5, or you can cut D9, though I do not recommend completely disabling the AMC circuit. If VR5 does not have enough range, lift the banded end of D9 & solder a 1K-ohm resistor in series with the diode, then adjust for 100% modulation or to where the AMC circuit just starts to limit modulation.

Cobra 29 ltd classic no modulation


check VR4 to make sure it isn't closed . Check D 11 to make sure it isn't clipped . Turn VR 4 clockwise till it stops then back it off a little .If D 11 is clipped replace it with another diode then try it again. If it doesn't work it could be your final or your driver so replace both..

Looking for cobra 89xlr transistor. 176-048-9-002 (2SC458-6)TR14, and a diode 151-088-9-001(IS2473)D14


Try some one like MCM electronics, you have the generic numbers right here for those parts.

I want to know what to cut or remove and tune to get maximum modulation and output out of my cobra 18 wx st ll thanks


VR2 is the modulation adjustment. I can't remember which way you turn it to get more modulation. It's usually to the left.

Hook up a watt meter. Turn it one way, and check it. If it is up a lot you got it. If its lower just turn it the other way.

Put a jumper in place of the diode at D21 which will increase voltage to the final and give you a little bit more. not much more you can do to this radio. It's the worst radio Cobra ever made. I wouldn't waste my time. I would use that one as a door stop and go get a cobra 29. You will see more out of it.

You should not cut the modulation diode, you should adjust the potentiometer VR-4 for full modulation. By cutting the diode, you risk over modulating. By turning up the pot, you can correct for an over modulation.

If you are still insistent on cutting the modulation limiter, it is D11, located directly in front of VR4 and C73. Looking at the radio from the front to back, it is in the right corner, apx 2 1/4" from the back and 2 3/8" from the right side.
