Icom IC-F3001 Handheld Bad Audio
« on: October 30, 2021, 10:09:37 AM »

I have a commercial Icom IC-F3001 VHF portable that I've had for many years and just discovered the receive audio is really bad: distorted, scratchy, garbled. When I plug in  the should mic it sounds fine. Xmit audio is fine either way. Does anyone have any suggestions? OTHER than sending it off to Icom service. Min shop charge is $92.40 and the radio was only about $129 when new.

Thanks. 73

Bad internal speaker?

That's what I'm hoping. I'll look for an external I can try plugging into the spkr jack like the shoulder mic, but it'll probably sound fine, too, like the mic.
I guess the next step would be try to crack it open and see if I can even access the internal speaker to replace it.
Thx.

This sounds like something on the speaker membrane.
When I was working in a two-way shop many years ago we would get this kind of problem a lot.
As long as the object is magnetic its pretty simple!
Just use a stronger magnet to pull it out.
I had a large antenna magnet foot in a zip bag and moved the antenna grill of the handheld in a circular pattern on the magnet. Usually I would get grains of iron filings on the zip bag.
The bag was there just for making it simple to clean the megnet

That sounds like a slick solution! :) I can see in the speaker grill a little, though, and it looks clean. Sounds more like a blown speaker to me.

The trouble is, I can't get the antenna connector nut off in order to get to the speaker. It has a  nut recessed into the radio housing that has 2 notches that require some special tool to unscrew the it. Might have to fabricate something just for that nut.

Yes, that's exactly the tool I'm looking for. But I don't know the diameter I need.... :(
