## Description

Product description 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. In the Box UV-25X4 Mobile Radio DTMF Handheld Microphone Vehicle Cigarette Connector Power Cable (4.5') Vehicle Mounting Bracket Screws & Mounting Hardware Easy-to-read Manual (written in the US) RJ-45 to Kenwood K1 Accessory Adaptor BTECH Radios are not like other similar looking radios. BTECH radios are designed in the USA with custom firmware and internal hardware differences. BTECH radios are backed with a full US support. A BTECH label means you are getting the best radio available! A few of our highlighted differences are below 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. Pair the UV-25X4 with the Nagoya TB-320A Antenna and RB-50 Magnetic Mount for easy installation with the UHF antenna connectors. 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. Technical Specifications BTECH UV-25X4 VHF/1.25M/UHF Tri Band Radio BTECH: We are proud to be here in the USA BTECH radios are designed and supported right here in the USA. A BTECH label means you are getting a radio with real US based support, and development! If you ever have an issue, our team will be prompt, knowledgeable, and supportive to ensure your radio operates exactly as it should. UV-25X4: SECOND GEN. 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

Review: Great little radio! - If you have a vehicle that you would like to install this in but don't have much space, this is seriously the radio for you. It is a very capable radio, yet very tiny. I can literally hold this thing in the palm of my hand. I drive an $800 car so I have no problem drilling into the dash and mounting this thing. There have been a lot of complaints in the reviews and I was skeptical about buying but decided to dive in anyway and I'm glad I did. This radio has held up well within the past month or so that I've used it, I've reached folks about 22 mi away using a larsen tri-band antenna. I'm seriously considering the 50x2 as a base station because this worked to well. As for the complaints... Is there an audible click? Yes. It is insanely loud and annoying? Annoying yes, loud no. I don't use 200mhz so I never have this issue. Is the fan loud? I actually laughed, it's really not that bad. It winds up while transmitting and sounds like a little rc car. While driving, this is not very noticeable and I just ignore it and enjoy my $100 radio. I also read that when using the radio powered via the cigarette lighter, it will heat up enough to melt. This did not happen in my case, however, I wired it up to my car battery for a more reliable connection. As for the programming side, do yourself a favor and download Chirp and use it. Makes this radio SO much easier to program, although you should know how to do this manually. Admittedly, this does take some time. My only complaint is the scanning. I have to enter the freq range I want to scan, rather than just select a band and hit scan. Minor complaint, but just what I prefer. I'd recommend this to anyone looking to jump in and not spend a whole lot of money.
Review: Good Multi-Band with 220 for the Price - SImple radio, easy to program with CHIRP. Set this up with a Tri-Band antenna for my RV and it works well. Power within a couple of watts of rating. Better with an external speaker, as the internal one is tinny sounding but radio sounds good with an external speaker.

### ⭐⭐⭐⭐⭐ Great little radio!

### ⭐⭐⭐⭐⭐ Good Multi-Band with 220 for the Price
*by R***N on April 24, 2025*

SImple radio, easy to program with CHIRP. Set this up with a Tri-Band antenna for my RV and it works well. Power within a couple of watts of rating. Better with an external speaker, as the internal one is tinny sounding but radio sounds good with an external speaker.

### ⭐⭐⭐⭐ Your best option for 1.25M
*by T***D on March 3, 2018*

I haven't had any of the problems that others have had with this radio, but I'm using it a bit differently. As I have another rig for 2M/70cm, the UV-25X4 is used exclusively for 1.25M with a monoband 5/8-wave whip. There aren't many options for 1.25M rigs beyond HTs, and I was happy to find the UV-25X4. It was mounted as shown in the attached pic. I bolted the rig mount into an aluminum plate, and slid the plate into a pocket behind the passenger seat, running the power cable to the cig lighter jack. This means that I can't see the display while driving, but I don't care. I can change channels using the mic, and I seldom need to adjust the volume. An external speaker was added using this CablesOnline 6in 3.5mm StereoTRRS 4-Pole Male to TS Microphone iPhone Adapter, Black (IP-MIC2K) handy adapter. No trouble at all. I used a simple inline ethernet cable (M to F) to extend the mic cable. Easy. Since my cig lighter jack is off when my car isn't running, the concerns over "parasitic current draw" never materialised. The programming cable arrived two weeks after the radio, so I had to program most of the repeaters manually. Seriously, it wasn't that hard. I'm baffled by people here that say they couldn't do it. I just followed the instructions. When the cable came, I used CHIRP to add a few other out-state repeaters and the rest of the simplex channels. There were no problems with performance. A few repeaters can't be reached in low spots while driving, but I doubt that more power would make a discernable difference. TX audio was reported as good, RX audio is nice. Since I am only using the radio for 1.25M, the issue of the relay clicks never showed up. While I haven't put it on a good watt-meter, no one I've been talking with has noticed the ten-second drop in TX power. Putting it on a cheap watt-meter didn't show any drop after 25 seconds. I dislike when reviewers attribute quality problems with *their* radio to *all* radios. I had NO issues with intermod, unlike using HTs for 1.25M. The filtering for 1.25M is very good, and I'm using a monoband whip. A tri-band whip is an intermod magnet. No problems picking up engine RFI, in spite of using the cig lighter jack. There are a lot of menu settings, but they are all "set and forget". In using this for two months, I've never had to change any setting. The radio has also been in my car for two months of Minnesota winter (cold!), and it hasn't affected the display or needed time to warm up. Don't know how it will handle the heat yet, but it's not very hard to take out, either. CONS: reverse burst (Menu 55) doesn't work, or doesn't work like the manual says it does. The radio also makes a brief sound like a pinball machine when you turn it on, and you can't turn that off. Adding the programming cable, TRRS adapter, and ethernet extension also added to the cost -- but not everyone needs those, either. As I said, there aren't many other options for 1.25M use -- and the non-HT options aren't nearly as easy to mount as the UV-25X4. I would absolutely recommend this to anyone looking for a decent 1.25M FM rig. EDIT: Put this on a Bird watt-metre, showed 17W and no drop in power after 30 seconds. Product description states 15W average power on 1.25M. Will update after 6 months, but as of 3 months there are no problems with daily use. NOTE: BTECH now offers a 50W amp BTECH AMP-220 Amplifier for 1.25M (220-225MHz), 30-50W Output (2-6W Input), Analog and Digital Modes, Compatible with all Handheld Radios: BTECH, BaoFeng, Kenwood, Yaesu, ICOM, Motorola for this radio. EDIT: I've now had this radio for a year without problems. I use it daily, and I've added a few 2m/70cm repeaters to the mix. Ignore the fear-mongering critics. EDIT: Nearly two years with this radio, in all weather extremes. It still functions great.
