What customers say about "Key Specs"
Uniden PRO510XL 40 Channel Compact Mobile CB Radio
  • Got this radio for road trips with my buddies. Easy installation, compact and works great. Fun and easy working with right channel radios.
  • Luckily this radio has a very good automatic noise limiter (ANL) which is very effective in reducing overall noise.
  • No beep-beep-beep crap unlike the big Uniden I have. No sounds when switching between channels or pushing buttons.
  • I got this radio about 9 months ago and it was a very good functioning radio until it broke. it does not transmit or receive any more signals. To me, it's not worth fixing up for the price.
  • Quality sucks I’ve tried to tune antenna to know avail and the lack of ANL is quite a bummer I bought the 510 to see if that one is any better.
Uniden PRO520XL 40-Channel CB Radio
  • Awesome little radio. Purchased this to communicate vehicle to motorcycle on a beach trip. Worked perfectly. So small, was able to mount in the lower center console of my 2010 Dodge RAM. Add a magnetic K40 antenna, tune it, and it has great range.
  • For the money, it's O.K. Every time it is first powered up it is on channel 9, otherwise, 5 stars.
  • I like the form factor, nice and small, love that it doesn't change channels after you shut off the key, I love the looks.
  • From the product description "A bare-bones, ultra-mobile 40-channel CB Radio" They aren't kidding. There are no fancy features with this radio. If you just need to talk and be heard this is all you need.
  • This radio works well for my purposes, communication between work vehicles not more than a half mile apart on the road. I give the radio four stars because it jumps channels, though infrequently.
  • Very hard to see channel indicator in daylight. Also, squelch control is way too sensitive. Very small radio that would work for occasional use. The transmit audio is good, from what I was told.

What customers say about "Transmitter"
Uniden PRO510XL 40 Channel Compact Mobile CB Radio
  • They're great, with much better transmission quality than the Nextels and no hassle of all-call bothering the folks who aren't driving trams, or remembering who is on what Nextel.
  • I've been using 510's for 15 years. Best bang for the buck. Works great, sounds great. Others always think I'm running a high dollar radio.
  • have roughly a 7 mile range with this radio, the signal is great regardless of what else I have on in the vehicle.
  • If you want a reliable 40 channel CB radio that broadcasts well and receives well this is the radio for you. It is is rated at the same output power as any full size radios, but is small enough to be mounted in tighter locations.
  • It worked great - for a few weeks. Now I can't transmit at all, nobody ever hears me and yes, I had the antenna tuned. Also the output ports in the back are on the fritz.
  • Well I gave this guy a run for its money. It lasted about 18 months in an open top rock crawler. It gave up the ability to transmit on my last run. I tried to fix it. No dice.
Uniden PRO520XL 40-Channel CB Radio
  • It works well. Hah, better than the "export" cb another driver has. Crystal clear transmit and receive audio all in a compact LEGAL package.
  • Though at the lower range of price, it is a great CB radio. Specially for beginners or if on budget. Clear transmit/receive and easy to use.
  • I installed in my 93 YJ for trails and even on the open road it pulls in and transmits for a long ways. The compact size is a great plus, it will fit almost anywhere.
  • It is extremely powerful with my 4ft Firestik antenna. I can easily transmit over 2-3 miles which is way more than I need in a jeep.
  • I am able to transmit and receive signals, but rarely. Most of the time I just hear static, noise, and garbled transmissions. When I turn up the squelch control to filter out noises, I rarely hear anything at all.

What customers say about "Receiver"
Uniden PRO510XL 40 Channel Compact Mobile CB Radio
  • Use this radio in a few Jeep Wranglers, holds up well, good reception and loud speaker!
  • he radio get very good reports from truckers out on the highway, even with the tiny little microphone it comes with.
  • These are still some of the best radios for reliability, ruggedness, and receiver/transmit capability.
  • Wanted a CB for OTR travelling. Mostly listening regarding traffic tie-ups, etc. Receives well, reasonable transmission.
  • Installed Radio not receiving, tried to get a radio check, cannot raise anyone. Cannot hear anyone talking on the unit even with the squelch turn down. Hopefully the new unit will work properly.
Uniden PRO520XL 40-Channel CB Radio
  • CBs all put our the same power and the main difference is the selectivity which cuts back on off-channel noise. The selectivity is much better that some cheaper ones I have owned and it does not jump back to Channel 9 when turned off or when power is lost like some cheaper ones.
  • Wanted a CB for OTR travelling. Mostly listening regarding traffic tie-ups, etc. Receives well, reasonable transmission.
  • Great radio. Long receive.good TX to. Never even pluged in that little mic so i cant comment there, i use a road devil power mic barley on,mostly just for noise canceling,very clear sounding and way too much power cranked up.
  • Very strong signal both transmitting and receiving.
  • Perfect size for what I needed to mount onto my Jeep TJ. Broke fairly early. Will not transmit or receive any more.

What customers say about "Features"
Uniden PRO510XL 40 Channel Compact Mobile CB Radio
  • This is my first CB and I loved it. It's very easy to set up. The sound is amazing, it fits right into the glove box of my jeep. It is a very straight forward product and gets the job done.
  • I also like the fact that channel selection uses knobs instead of buttons -- no risk of bumping it and getting off-channel when you are busy.
  • The controls are fairly sand/weather resistant. The 510XL is light in weight which is important in a sport where every pound saved accounts for better performance.
  • It has an amazingly clear speaker for being such a tiny size. The controls are solid and sturdy, not loose and wiggly. When you change channel you feel a nice solid "click" so you know your moving the knob.
  • Old school LED display is hard to see in the daylight...excellent at night tho.
  • Speaker power out could be a bit better with some type of tone control.
Uniden PRO520XL 40-Channel CB Radio
  • It's a small unit with many useful features. ANL, Gain, volume and squelch controls on the front and a PA outlet on the rear.
  • This is about as perfect of a CB as you could ask for. I really like the dip switch idea for quick changing to external PA or emergency broadcast channel 9.
  • The unit has a internal speaker that is very loud and is whisper quiet when tuned to filter out static so you can leave it on without listening to garbage the whole time.
  • The stock mic is cheaply made with passable modulation. The mic cord is very short, but I can live with that. Since linear amps are a 'No-No' get a decent power mic if you want to be heard.
  • It works fine as a CB. What I do not like is the PA function. When I turn my PA on, I have to change channels and turn the squelch up so that the channel I am on doesn't play through the PA speaker.
  • Very low frills unit. There is a PA function, but that's about it. The Power, squelch and Up/Down channel buttons are not lit and can't be seen in the dark. There is no "scan" feature. The internal speaker sounds pretty thin.
