Uniden SR30C Review

In our society, information and communication go hand-in-hand. We communicate with information, and communication itself uses the information to operate. One is not possible without the other.

For this reason, walkie-talkies have become a versatile device for people. And SR30C Handheld Scanner by Uniden is one of the best models you can get. Here is why.

Scope of Delivery

Whether you’re merely a hobbyist or a journalist looking to listen to some channels for information, Uniden SR30C is one of the best radio scanners that I highly recommend.

As a scanner, its primary function is to allow the user to listen to a wide range of channels; usually, public services such as police, fire, and emergency medical services. You can almost instantly keep yourself up to date with the recent events and information shared over the channels.

The scanner feature is also handy for multiple groups that need to be in regular contact with each other, like police patrols, to get updates and urgent information from each other.

A package of Uniden SR30C contains the scanner itself, the antenna, a belt clip, a USB cable, a strap, and an Owner’s Manual. The scanner is very light, allowing its user to carry it around without slowing them down.



Setting up the radio scanner is very easy and quick. All you have to do is take all components out of the box, attach them to the right sockets, put in the batteries, and voila! Your SR30C handheld scanner is now ready to use.

A slightly more detailed setup instruction is in the Owner’s Manual, which you also get in the package.



The Uniden SR30C is not waterproof. The only time it can contact water is when you use a damp cloth to clean it. Even then, I strongly advise against using excessive amounts of water to avoid damaging the device’s delicate components.


Power Source

Both rechargeable and non-rechargeable AA batteries can power Uniden SR30C.

For non-rechargeable batteries, I recommend using two AA alkaline batteries to power up the device.

For rechargeable, you can use the 2300mAh Ni-MH batteries that come with the pack. The device may last up to several hours, depending on use. You can also recharge the handset using its dedicated micro-USB cable.



Instead, the range depends on the users’ systems, which are the Simplex and Repeater Systems.

Simplex systems operate within a line-of-sight range and typically use just a single frequency for transmission and reception. It has a range of 1-8 miles, depending on the terrain, along with other factors.

On the other hand, Repeater systems use two frequencies, one used to transmit from radio to repeater, and the other from repeater to other radios. You can place repeaters on top of buildings or radio towers, which give it a range radius of about 25 miles.




Uniden SR30C has over 32 000 frequencies and private code combinations available. These frequencies ranging from amateur radio, public, government, and military services, are legal to listen to, so you don’t need a license.

The frequencies available for USA band plans are:

  • 25.00000-27.99500 MHz, transmitted over the citizens/business band;
  • 28.00000-54.00000 MHz, over 10-meter amateur band;
  • 108.00000-136.99166 MHz, over aircraft band; and
  • 137.00000-150.77000 MHz, over the military band.

There is also a band plan for Canada, which is available in the Owner’s Manual.





Uniden SR30C is a versatile tool for you to have, whether you’re just listening to available services or in an organized group.

Its main attribute is its scanning feature, which allows its user to cycle through the available frequencies, ensuring you can receive the transmission almost instantly.

The device stores frequencies, and those channels group into banks. Each bank can contain 50 channels. The device lets the user customize where they keep their channels.

These banks can then be enabled or disabled by the user for more efficient scanning, preventing the least relevant channels from disrupting a scan. Other than disabling, the device also has a Lock-out function that skips over specified channels when scanning.

A more advanced feature is setting priority channels. Uniden SR30C checks priority channels every 2 seconds so the user won’t miss any transmission from that channel.

Users can also search for new frequencies that are not in the scanner. Using the search function, the device will present active frequencies and choose which to store.

Uniden SR30C also has a Close Call feature, which you can set to allow the scanner to detect any strong radio transmissions in the area and display its frequency. You can then adjust the squelch to your preferences, to either let stronger transmissions through or also allow weaker ones.

Other than functions available in the scanner to let users customize their scans, Uniden SR30C can also be customized using computers.

These features are only a portion of all that Uniden SR30C offers. It has more features available to let you utilize it to the fullest.




As of now, the Uniden SR30C on Amazon is $ 104.99. Its original price, as listed on the manufacturer’s website, is $119.99.
