This "talkback" feature may be due to someone having modified the radio by adding a small resistor between the speaker circuit & circuit ground.Another cause could be the shield lead in the mike plug shorting to the plug itself.

SOURCE: what exactly does the anl nb/anl button do on my

ANL stands for "Automatic Noise Limiter" and NB stands for "Noise Blanker".

The ANL gets rid of a lot of interference noise caused by mechanical noise from motors and other electronic components in a car.

It also gets rid of noise from other sources of interference.

The NB is for extreme cases of noise, but can slightly lessen your receive sensitivity.


Basically both functions help decrease interference noise.

Where can i get tuneup specs for Cobra 18 wx st extra low modulation

The cobra 18 wx st is the worst radio Cobra ever made. I don't know why they still make it. It's not gonna do much no matter how much you tune it up. Its a bad radio.

Get a cobra 29, and turn VR4 all the way counter clockwise.
(this will not work on the 18)

VR2 is modulation in the 18 wx st. adjust it while checking on a watt meter to see when its all the way up.

I have a cobra29 wx nw st. its been peaked and tuned, an echo board installed, and soundtracker override when i key up if my mic gain is over 1/4 the way up it makes an awful racket what do i do?

is there talk back installed? if so its probably too loud. You are getting feed back. The talk back should be low, just enough to hear it to check echo. 470 ohm resistor is perfect.

Have cobra 29wxnwst radio. Truck sat for 3 months

Turn up the RF gain all the way and leave it.

RF gain is basically how open your receive is. There is really no reason ever to have it down unless you are trying to hear only close stations to you.

If you RF gain is up, your mic pins my be oxidized, or mic bad.
Try a different mic, and or clean the contacts in the connectors.

Transmits but doesnt receive

If the meter shows that it's receiving something, the microphone may be the problem. Another possibility is the speaker & plugging an external speaker in would confirm this. Aslo make sure the squelch control is turned all the way to the left (counter-clockwise) & the RF gain is turned to the right (clockwise).
