Uniden 980 Talkback Problem

[Riverman]

Glad you got it worked out.
I'm slightly impressed with my 980. I should run it more than I do.

Good radio.
Turned my RD down from 3/4 to 1/4 and the locals can tell no difference. Loud and clear.

Hmmm! My D104M6B on that 980 may be culpable. Shall try turning down some. Likewise, doesn't do it with stock mic.

Did you turn down the AM pot? Need to still do that to mine.

Mine does it even with the stock mic...no idea.

Son is running it in the pickup and it’s not noticeable there. Very annoying on the bench though.

Yes. To 1 1/2 watts.

That is surprising. And would be very annoying.

Riverman,
I use a snap on ferrite bead on all of my radios mike cords right at the plug to the transceiver to stop such annoyances.

Read your post, applied the same solution and totally forgot what thread I had read.

Sure, everything into or out of the radio needs filter consideration.
I “knew” that. Ha!

Don’t know why it escaped me. It’s not as though running the roads in a big truck had the mike & cord hanging near my face or anything.

Worked VERY well. That $5 ferrite killed $70 worth of noise.

Guess I’m going to be buying that size in bulk. It’s just TOO useful in mobile

Thanks again!

You care to share what size you used to fit the mic cord. I see several in my searches. Maybe I won't have to do the trial and error.

Helps with grip on the President mic.

My favored Uniden 980 package for big truck mobile has:

(2) Cables from West Mountain Radio ClearSpeaker; Power & Audio

(1) Microphone Cord

(1) Coaxial Cable Jumper from Radio to RM ITALY KL203

(1) Coaxial cable to antenna

That’s a minimum (5) ferrites.

$25 + ship.

Not needed? Store till next project.
Need one at each end?
While antenna coax is somewhat separate,
buying (10) ferrites isn’t that expensive.

Besides, who has only one radio?

PALOMAR ENGINEERS
FSB31-1/2”
$5.50

This is what I use. Can’t remember where I got them though.
