How to adjust modulation on a cobra 19 ultra III cb radio

www.cbtricks.com has the information you need.

throw that antenna away and get a lil willie by wilson. Cost about $40.00 should make a great improvement

4 watts max

you can't

google it

i got a couple of them and i have them talking really good for what they are. if you go inside you can turn up the pods also you can take a small screwdriver and spread those coils inside near the back of cb!

find DM1 and clip it. then you will have full modulation.

un-solder 1 leg of D11 diode, pull it out of the board, and make sure it does not short against anything.

That will bring your modulation up all the way. there are other adjustments that can be done, but without proper meters, you will most likely mess up the radio.

D11 will be a big step up any way.

You need to buy an antenna that is designed for use with a CB. A couple of good ones are the Wilson 1000, Wilson Lil' Wil, K30, K40. You will only pick up "everything" within the 40 channels with that radio.

The external speaker jack was not designed for a head set. It has too much power it over loads head set. You need to solder a resistor in line with the negative wire. You will have to experiment to see which value gets the audio just right for the head set you are using.
