UV-25X4 (Second Generation) 25W Mobile Two Way Radio
Second Generation
The UV-25X4 is very much the same radio, our users have come to enjoy, with several new functionality improvements. The UV-25X4 has seen several performance improvements and tweaks in its second generation release.
RJ45 Audio Input & Output
The UV-25X4 has new menus and operations that allow audio I/O from its RJ45 microphone port. This allows the UV-25X4 to be installed for custom applications, where users want more control on where the speaker and mic audio is routed to.
VOX Handsfree Support
The UV-25X4 (Second Generation) includes VOX support. VOX allows for handsfree use with your favorite audio accessories or the included handheld microphone.
- BTECH radios use an upgraded Power Chipset
- Customizable PTT Return Times: When handling multiple conversations, the radio allows users to customize if the radio automatically switches to respond to active channels, or allow the user to set one channel default to transmit on.
- Dual Synchronize Display Mode: Synchronize Up to 2 Channels - and display both their channel name and channel frequency!
- Microphone Audio Gain Settings: Sound great and customize your microphone output for any repeater
- Expanded Frequency Range Support
- Auto Power Off Function: Save your battery and prevent unnecessary power draining
- Channel Mode Editing Settings: Edit saved memory channels on-the-fly; our radio does not require you to delete a channel to make changes
- New Scanning Modes: Auto Scan (Scan with a power reboot), Scanning Resume, and Variable Frequency Scanning
- Quad Watch Delay Time: Allows the receiver to stay on the secondary channel longer after incoming transmission - customize the delay up to 50 seconds; This avoids manually channel switching when you are engaged with simultaneous contacts on two frequencies
- Randomization Privacy Mode
RJ45 to K1 Audio Adaptor
The UV-25X4 also includes a RJ45 to K1 Audio Adaptor, allowing you to use K1 audio accessories from our BTECH handheld radios with your mobile radio!
The radio includes special menus to allow audio to be routed both through the UV-25X4 and K1 accessory, only through the radio, or only through the K1 audio accessory.
Uniquely customize your UV-25X4
The X-Series Mobiles use our Multi-Color LCD display screen. You can adjust the complete display colors to be exactly as you want it. Beyond the display, you can fully customize your channels to display their alpha-numeric names or frequency settings.
There are 128 programmable memory channels. You can add or remove channels from scanning list. You can easily program from a PC or right on the radio itself.
Group Tones supported
The UV-25X4 supports the most common Analog Tones. It supports CTCSS, DCS, 2Tone, 5Tone, and DTMF calling methods. Set-up your calling methods to call by group tones. Tone calling (private line) is required by most repeater applications and the UV-25X4 supports the latest standards.
The UV-25X4 can even send DTMF tones. This allows for sending ANI (Caller ID) or remote commands that require DTMF tones; or it can receive incoming DTMF tones to allow for remote stun or kill commands
Quad Watch and Display Sync
The UV-25X4 operates as multiple radios in one, with either VHF or UHF as the ‘Main’ band, while simultaneously watching up to 3 other frequencies or channels; and, if you like, you can configure your UV-25X4 for simultaneous VHF-VHF or UHF-UHF operation, too!
Dual Sync Display:
With Dual Sync Display, you can synchronize channel lines to one or two channels. This allows you to sync display ‘lines’ to a single channel allowing the user to have both frequency and channel name data displayed simultaneously.

BTECH UV-25X4 VHF/1.25M/UHF Tri Band Radio
Second Generation
Dual Watch monitoring VHF/UHF and 220Mhz: The 220 MHz band antenna lowpass filter is switched with a relay and the 2 meter lowpass filter and 70 cm highpass filters are switched with PIN diodes - resulting in a audible relay switch noise when monitoring 220MHz with VHF/UHF simultaneously. A relay that completely isolated the 220 MHz RF filter won't impact the RF performance of the 2 meter/70 cm bands. If monitoring multiple 220MHz or VHF/UHF simultaneously the relay is not heard or used.
- Q: What is the product support?
- A: If you have any issues or concerns, reach out to our support team, who will be happy to assist with any setup issues. The UV-25X4 includes support against any manufacturing defects for a full year.
- Q: Is it compatible with other analog radios.
- A: It will support 99% of analog systems. The UV-25X4 supports all CTCSS, DCS, 5TONE, 2TONE, and DTMF call tones used by a majority of analog radio systems.
- Q: What is the maximum range?
- A: Range varies on topography: Repeater Use: Up to 100 miles | Hill to Valley: 36 miles | Open Flat Terrain: 3-5 miles | Urban/Outside Buildings: ~1 mile

I have been using this rig for about 4 onths now and just love it It sounds q5 both xmit and rcv I have had good audio reports from my friends and very little intermod issues. It is tiny soo it was easy to find a spot for it in the dash of my F150. it was reasonably easy to program but I could not get CHIRP to work with it. Apparently there is a data connection issue with the rig All in all I give it a 4 out of 5 for overall performance in the short ter We will see how well it lasts…. de VE3GJ

I’ve owned this for about 2 years. I have a general license and would consider myself a casual user/ listener of local nets. I use this in my truck, home and rv. I bought a 10A power supply for use as home base station. Very enjoyable, no issues or problems on all 3 bands. I have small Trivandrum antenna mounted on roof peak about 20’ up, i can hit 220 repeaters about 50 miles out. Other 2 bands as well. In my opinion great entry level radio for new users or casual users like myself. Chirp makes programming a dream, very easy.

The is a good practical radio, for those who aren’t looking for super high power and who want a radio with the 220 band. I’ve had it for a few months. I probably use it once a week when I am away from my shack

I have had this radio at the house for about a month now. I love the radio. It’s a pretty good tri-bander. I use it as a base station. I am a newer ham, only a month or so with my ticket. I use it with a CX-333 about 20′ in the air. I am impressed with the range. I am having trouble finding an earpiece for the thing though. Multiple bought, but the TRRS connector never seems to be the right configuration.

What is a good home base antenna for a btech uv-25×4 tri band 25W mobile radio. I would like to install it on my house roof.

I needed an inexpensive mobile tranceiver for my base operation and picked up a BTECH UV 25×4 on sale just before Christmas. The BTECH DMR-6×2 that I have owned and used extensively over the last two years has been a “Tank” and has always worked great even after several accidental drops onto hard surfaces. So I thought to give the 25×4 a try. What a bargain! I intsalled it on my homemade ground plane base antenna and 20 amp powersupply with a Surecom SWR/Power meter and was excitedly pleased. It transmitted at a full 25.24 Watts (SWR 1.01) on VHF and 13.94 Watts (SWR 1.00) on UHF. Voice quality reports have been good and I use it everyday on a local repeater net. I certainly got what I paid for with this radio!

Great little radio I have only used it for listening so far, set to take the test for technician class in couple weeks I am chomping at the bit. I love this little radio though I have had so much fun with it. I have my gmrs license and this little radio has all the gmrs freqs.
Not that I would dream of doing anything illegal I have a gmrs handheld baofeng. It works great as well. I haven’t heard of or found a btech or baofeng radio that doesn’t work great, but everyone seems to look down on them as cheap junk. Well I have spent most of my life on the poor side of the tracks, so I guess I will just enjoy my little cheap peice of junk and those on the other side of the tracks that have deep pockets can brag about how much they paid for the radio they have. I can talk to anyone I want to. The btech handheld gmrs radio I have talked about 14 miles from inside the house to inside a car going down the road.
It doesn’t get much better than that. 73s y’all.

I have had this radio for several months, and I like it. I use it as my mobile rig in my truck. It sends and receives good, strong signals. It was easy to mount in my truck, took up very little space, and was easy to use.

Only had the radio for a few days. So far, I do like it. Especially since it has 220 MHz built in. However, there is one thing which is rather annoying – the “welcome” and the “goodbye” beep. It is loud and I have not seen a way to get it turned off. Not in the manual, which is actually very good, nor within “chirp”. Anyone know how to disable those beeps.?
