The squealing you are referring to is usually due to to a disabled automatic modulation control circuit.
one or more dry solder connections could cause the intermittent operation.

I have a dx98vhp and it sqeels* when i key up when the talkback is on. I've tried adjusting the power and i can't figure it out. Thanks


the talkback is too loud. there is no way to adjust the talkback volume on this radio. Talkback is really just so you can check how your audio sounds and your echo. Once it set, there is really no need to have it on.

Turning down the gain on your mic will stop the squeal.

the squeal is cause by feed back from audio from the talk back being heard from the mic.

Just replace your talkback cable, and your headset will work good as new. You can purchase the talkback cable here:

Want to get talkback in a cobra 29


When you key up the mic ungrounds the speaker so you don't hear anything through it, so to get talkback you're putting a 100 ohm 1, or 2 watt resistor between the switched side of the speaker and ground, now when unkeyed the mic grounds the speaker as usual, but when you key the resistor allows a bit of audio from the audio amplifier, not decoded RF, to still get through. I think the pa/ext spkr. jacks are a convenient place to connect it. You may decide to control talkback by running the circut thru a switch like brite / dim switch . Want less talkback, use more resistance, 150 ohm . Too much talkback can become feedback . I hope this helps, J

I have a Cobra 29 wx classic and i get talkback through the speaker, and it doesn't have talkback installed!! How do i change this and what is wrong!! The radio works awesome rx/tx, but it just has this...


Have you tried using a different mic that you know is working properly? If it still has feedback, then someone has installed talkback. Take the top off, check for a resistor between external speaker and pa speaker ports. Remove resistor if it is there and that should remove the talkback. Hope this was helpful.

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
