(Automatic Noise Limiting) feature, it simply cannot be beat.

It is compact & has great features like: Automatic Noise Limiter (ANL) cuts out alternator & engine noise, Public Address hookup (PA) allows you to hook up a speaker and yell at your buddies or the bad driver in front of you, and a RF Gain knob

Works well, simple features and small enough to fit in a space deficient Jeep.

There are no fancy features with this radio.

This unit has just enough features to be taken seriously for use in the back country

The RF Gain being one of the better features because you can turn it up to pull in weaker more distant signals and then adjust the squelch knob to block out the "static noise"

I like the PA feature, but you get a little squelch feedback on the PA unit when in that mode

The ANL and gain are nice features

Works easily and the RF gain is a nice feature

Great feature.

If you want a simple, small, clean looking, durable radio, with a good feature set then this would be a good fit for you.

For a basic radio, it has good features, i.e. S/RF meter, switchable ANL, RF Gain, and PA.

The 510 does however lack a PA feature, so if that is important to you at this price point, the 505 would be better

- It's a small unit with many useful features

Great features

It feels like they put it together as cheaply as they could

I have an external speaker that I'm going to mount and hook up as it's sometimes hard to hear the unit inside the console.

Everything seems to work as it should.

Radio works as it should
