President Lincoln II+ poor audio

[slowmover]

Back in the 90's I bought a Realistic AM CB that had built in DSP (RS sold a cheap external DSP as well at the time) . I did not enjoy the sound, and exchanged it for the SSB radio at the time; TRC-465 which was a great radio, still kicking myself for selling it.

If you want great DSP consider the long out of production Timewave DSP599ZX which can be continuously tuned to however you want it to sound. I have even used it to clean up crappy analog Inmarsat recordings that were noisy and received using wrong RX bandwidth and heavily compressed.

This is what I’ve used the past (8) years. Over 500k miles. Cleans up the audio hash nicely on any “digital” radio. A BPF quiets things a bit more in used in conjunction.


I’ve linked videos elsewhere, but they don’t do justice to the ability of DSP to clear out the underbrush.

A CB without DSP isn’t worth using. There’s that which ameliorates, and there’s that which solves.

Standard noise abatement and DSP is another world in operation.

The 411CB + W-M DSP CLEARSPEECH puts my big truck radio rig into territory outside what the experienced would believe possible in a composite body fleet truck. (Feedpoint chokes at each antenna, as well).

Any mobile system benefits

Bought the (15) bead version of this Palomar Engineers sleeve choke a few years ago in a big truck experiment. Am now using it under the headliner of my pickup truck install. Wowser. Didn’t expect it to deal as well as it does with the noise where I’m parked at home.

Big difference (without BPF or DSP).
Am using LMR-400 (shielding matters in mobile).

No other filters at present.

But, expensive, now (wasn’t cheap when I bought it, but labor to build shot up since).

With the KES-5 under drivers seat and aimed at carpet, the Lincoln audio is way above normal in quality with the big & heavy sleeve choke the only in-line device.

I’ve left room for addition of the unit below to take things the rest of the way. A BPF will follow (another vendor possibly).
