Re: Fuzzy or static tranmit

I know this may sound like an odd answer, but what are your SWR's? If they are high, you will experience some WEIRD audio problems.

Will not tranmitt

need more information but it could be a number of things.someone could have clipped the wrong diode to give it more modulation.Does it recieve at all? How about your antenna SWR , is it resonably low ? Is your power level low due to the tx problem?

My radio squeals with echo when my amps on

adjust your talkback to just open then set your echo to where you want it. Now turn your amp on and re-adjust both the talkback and the echo . If you have a speaker nearby the radio may be feeding back through it so move it away from your radio . Now start talking with the mic and adjust your echo because you should be able to hear yourself talk through your talkback.

I have an echo mic on my 29. I can't use mic gain at all without it squeeling. Can barely here my talk back in this position.

re do the talkback. take out the resistor for the talkback. and put in the talkback that is a little outta phase and you won't get that constant feed back. make sure all the modulation limiters are not cut also.. A good shop would tune up and talk back a radio correctly for $10-$15 dollars. any more and they are ripping you off. I make sure my customers radios do not squeal before giving it back. that means i may have to try different values for the talk back to be right. so the customer can have the mic gain 100 % and it be ok...then the microphone mic adjustment can be set also.. let me know if you need help

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.

My talk back is low cant hear it

You really don't want to have a loud talk back. Its usually controlled by your mic gain. the louder it is, the louder your talk back is.

Talk back is used so you can her how your audio is being transmitted. It makes a lot of sense when you have echo. use it to hear you echo to make sure its not too much.

The problem with a loud talkback is, if it is too high, you will get feed back in your transmit.

You should leave it where it is.

ICAN HEAR EVERYBODY BUT I CANT GET OUT I SWITCHED MIKS AND STILL CANT GET OUT people can hear me but when they talk to me all i hear is static

You said that you can hear everybody and then you said all you can hear is static. Which is it?

If you can hear everybody and you have switched to a known good mike, then you either have a bad antenna or you have a bad final amplifier caused by a bad antenna or by having transmitted at sometime without an antenna at all.
