The Conex 3300 models already have a Talk Back switch on ot that will turn it off which is disableing it already!! But for some reason you have to take it out then D80 is the number of the Diode inside the radio that controls Talk Back if you cut it or remove it your talk back will be gone!! Please take care in doing so because if you cut the wrong one you could destroy the radio!! And make sure the power is diconnected!!!

Thanks Dennis

If their isn't a switch you will have to go into it and disconnect it. I would recommend having a professional do this. It is very miticulous.

I want my talk back louder on my connex 3300hp

  • Under the top cover of the radio is the solder side and a 440 Kilo Ohm resistor (See Pic)

  • More resistance will quite the talk back. Less resistance will make it louder. You will need to experiment a bit to find the level that suits you. I would start with a 200 Kilo Ohm.
  • This is for the more common Connex with the knob that has an adjustment for echo/talkback. If you have the other on then say so and I will direct you for that one.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

How do i cut out talkback out of my connex 3300

There are many versions of the 3300 , however in most cases (not all) remove the yellow wire from the "echo" switch. Let me know if this helps.

How can i disconnect the talk back on a connex 3300 plus? pleasa be specific on directions. thanks

in older connex 3300's you cannot disable the talk back. Its part of the audio chain. If you disable the talk back you will loose your audio. There are 2 things you can do.

Hook a relay to the speaker so that when the radio key's id disconnects the speaker. (Big pain, not worth the trouble.)

The other will not disable the talk back but it will stop any squealing.

Use a noise canceling mic. An RK-56 will work great. You will get no squealing with that mic.

You can. Just wire a switch in between the resistor, and the solder point.

I have a 3300 connex, something is heating up, you key up and watch power decline, hooked up to an external meter talk back has been modified, radio has had some mork done in the past, all in case

if it has the RELAY talkback. REMOVE IT !!! put back to stock after few months to year or so. it will mess up the radios..
but power prob. check the rf finals, and audio transistors. those two will cause low rf power.
