Cobra 29 LX Receive audio mods?

Post by FAFFER »

Anyone know how I can improve the incoming audio on one of these?

It's all a bit distorted and splattery compared to a Uniden.

Most people sound like they're over deviating... :?

An extension speaker hasn't really helped.

A shame because I like the look of the radio. :D

Thanks.

Have you checked the detector coil is set correctly?

I'm not sure where that is...

It's as is from the factory. I'm fairly sure it's never been messed with.

Yeah. His sounds a bit cack aswell...

Maybe that's just how they are.

Just feels like the filters are too narrow...

I got one of these when they first came out (the EU one) as I was impressed by how smart looking they are. Build quality was not that great though, controls felt cheap and loose and had quiet TX audio. The receive on mine was ok, not great quality, but it was ok. I guess if I'd sent it off to somebody who was great at performing modifications and adjustments it would have been a better set but couldn't justify spending more money on what was a cheap-ish radio in the first place, it was what it was.

I really do like the look of it! That's why I've not just chucked it on the pile! :lol:

I've put my me3 on it, so it sounds alright now.

Will have a twiddle with this detector when I get chance!

Not so fussed about build quality, it only sits on 19 anyway round here...

I've got an immaculate, boxed one too, with dead TX, that's going off for repair soon! So that can be my collectable one...hadn't seen one for sale in years! Then two came along at once... :crazy:

Ok! I've had a good fiddle with L20 and it's certainly improved things!

Some people of HF sets with loud audio sound crap, but the majority are fine.

Thank you ch25 and chubby chops. ;)

The filters would need modified not worth the effort
