UVK5(99) AM/FM/DTMF Walkie-Talkie 200CH 20-1000MHZ Walkie-Talkie NOAA Weather Forecast with Flash Copy Frequency Tpye-C LCD Display for Hiking Camping Travel Two-Way Radio (Grey)

Buyers either like or dislike this little radio. It internal design is very different from most other HTs. I think I received a return. I've done lots of testing on it. Big surprise, it transmits everywhere. Pressing F+5 brought up the spectrum display which looked exactly like a video about the Egzumer firmware. Going through the menu items, there was no setting to leave the backlight on all the time, 5 seconds was longest time. It insisted on a 25 kHz step. I think it was an older version of Egzumer that someone installed, then returned it to Amazon. With Egzumer, this little radio does plenty to keep me busy. AM (air band) fixed, backlight always on, step set to 5 kHz, etc.The charging stand is really nice, a perfect fit. Battery (1600 mAh) lasts a long time, better then expected. Do charge it until full, then leave it on until it shuts off, then repeat, manual says to do that. Why do this? The charging chip records these 2 cycles to give greater capacity. If you have a DMM, you can measure the battery voltage & enter it using the menu, this gives greater accuracy of the percent. Menu 58. Actually, you should do a couple of charge/discharge cycles on any new product with a Li battery.Look up UVK5 flash with a browser. I did it with no problems at all. It now has the latest version 0.22 in it's little CPU memory, 98% used for Egzumer firmware. You can assign the 2 side buttons to do many things.If you want to work 220 band, this isn't the radio for you. It puts out 4.5W on 2 meter, 4.3W on 440, and a whopping 0.35W on 220. I tried it on 6 meters, 4.2W, 10 meters, got 4.0W. Next I checked for harmonics. 2M, (144) is good. 440 is very good. 6M and 10M are horrible! Only transmit on 144 and 440. The hardware supports listening on any frequency, 20 MHz to 1300 MHz, AM, FM & SSB, but transmit is FM only, limited by the main chip.My meter is only good to about 500 MHz, so I can't get a power reading higher than that. I did check the higher frequencies using SDR Console with SDR Play RSP2 & it does transmit up to 1300 MHz, covers the 33 (902 to 928) CM band and the 23 CM band. However, the power output is 50 uW @920 MHZ, 2.5 nanoW @1276 MHZ. Won't go far.Next, programming my repeaters and other frequencies assigned to channels using CHIRP. Just installed the latest version, that includes the driver for it. Along with 2M, 1.25M & 70 CM frequencies, I put 927.950 and 1287.9 MHz in 2 chirp channels, uploaded to the radio, no problems. Tested using SDR Console with SDR Play RSP2. Good, on frequency carrier but low modulation. Receive is very good on 144 and 440.It is obvious to me that this is a VHF/UHF radio. My tests revealed it's poor performance on the 11 M band. Why not just buy yourself a regular ol' CB?I'm impressed by the FM BCB tuner. Beats my other regular AM/FM radio. It uses a dedicated chip.Now, on to the antenna. We all know HT stock antennas aren't all that great. This one is better than the antennas from a Talkpod & Btech UV-5X3. I compared them using a good field strength meter. The Quansheng antenna was better, and like the radio, it is very sturdy little thing.Hope this info helps with decision, buy, or not. For me, it is a keeper.

For what you are paying, these are great radios. There is value for the money here. There is plenty of custom firmware available for them too. They are horrible at frequencies that are not meant for use with this. For example 27 MHz is only going to output in the milliwatts. If you stick to FRS/GMRS/MURS you will be fine 3-4 watts.CHIRP programming software will work with these. Note the programming cable does not come with this radio. You must purchase one. The Baofeng cables work. People often have problems with it for these reasons:1) The programming cable must be plugged into the radio AFTER it is turned on.2) The programming cable must be seated completely.Beware that you can set these up for illegal purposes. Be careful. However, it is a good option for a prepper.

I don't know about you, but I have quite a collection of Chinese-sourced handhelds. This will likely be my last purchase, as you can talk on only one at a time. What attracted me to pull the trigger on this was that its firmware is programmable. People with skills and excess free time have created variations that provide interesting features and functions that are not provided in the factory-provided configuration. Some people with more time and money than common sense are making major mods so this radio can be used out of band and in modes other than which it was designed. A good feature not found on the Baofengs is dual-watch. But this can be a pain, too, since it isn't simple to squelch one to listen to the other. Maybe this will be addressed in a firmware build I haven't found, yet.

Excellent packaging and quality made product. Definitely will buy again. Also fast shipper

Everything as expected and OK.Very rapid delivered.

I was surprised to find the radio did not work properly. I ask for a replacement and the replacement has the same problem and I will be returning it. The radio can not be progamed from a computer and unless you are up for a lot of time and effort programming in manually do not buy.

Work well, easy to use, CHIRP programmable and very broad spectrum TX/RX. What's not to like about them? Nothing!

I installed some new firmware, then used CHIRP to load the freqs I wanted for the local Boston area. The radio works okay for Ham use. Got good signal reports from local repeaters on VHF & UHF.The radio is not too hard to use, even for a very old Ham like me.The supplied antenna had SWR issues. Replaced it with a good dual band antenna.I programmed in the Meshtastic slot 20 freg of 906.875 MHz in AM & SSB.This allows me to monitor Meshtastic Node packets and check their signal strength. It's sensitive enough to hear weak LoRa nodes a few miles away!The super wide frequency range is my main reason for buying this radio!I am very happy with my purchase!
