Your gonna look in your radio by the transformer for a"d25" diode 25 is what is removed in this radio to add talkback. If you want to disable talkback you need to replace that diode as this radio is not stock with talkback. Someone removed that diode. Diodes only go in one way. Pay attention to the cathode marking on the board and on the diode ( --> ) no smaller than a 1N914 diode as a replacement.

My galaxy dx 88 hl works great but the talk back won't work on am but does work on pa what is wrong

if you hooked it up its wrong but I assume you didn't.First of all talkback is a feature that allows you to hear your voiceand you don't5 need a radio check because you can tell by your own voice how your radio sounds if you want it to work on am you need to attach a 33ohm resistor from the positive to the neg of the external and pa plug ins. the talkback will be on all the time by the way.

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.

Galaxy dx-66 squeals on talkback

timspur, hi. First off, using the talkback with a tuned Galaxy will give you problems, so you need to use a good noise cancelling mic like a RK 56, or Astatic 636. If your running an amp, that will only amplify the problem. Here is a mod if your comfortable working on your radio, to tone down the TB volume.
Talkback can become distorted if these radios have been "peaked," and there is no cure because the talkback just amplifies what goes to the RF section. Try adding a 470k ohm resistor from junction of C155/R207 to the junction of C187/R235 on the solder side of the board. This will also give you clean talkback on SSB and FM. Try different values of resistance to get the amount of volume you want. The less the resistance the louder the talkback will be.**
Hope this was what your looking for,, I know for a fact that the Astatic mics do help tone it down.
Let us know,,, Mechanic
