QYT has also released the QYT KT-7900D Quad Band
This radio is identical in specifications to the QYT KT8900D
Specifications brochure in both English and Chinese (click to view larger):
The form factor is similar to the QYT KT8900, but with a large and easy to read color display. The design is similar, but not identical to the KT8900D, its dual band “brother”:
It is worth nothing that this radio is quad-watch also. That it, you can monitor 4 frequencies/memory channels at once, instead of the standard 2. This is a really useful feature.
The QYT KT-7900D Quad Band Mini Mobile Radio is already available online here

programming software available from anywhere?
Hello, Happy New Year! You can download the programming software in the downloads page here. Thanks!
Do you have to use computer or can you program the radio directly with out any use of pc ?li
I don’t have the radio, but I suppose you can program it directly, just like its predecessors.
I bought this radio. You can program it directly, it just takes a lot of clicking. The software is slightly better, although not much. But I guess CHIRP will soon be updated to work this radio too.
But there is a big problem with this little device. The scan function does not work. Whenever you start scanning the receiver is locked to the last static channel/frequency although the display shows that the device is scanning through freqs/channels, this it not really happening.
Thank you for the info. I heard about this problem with scanning before. I don’t think the radio is firmware upgradeable, unfortunately.
I only paid 87USD for it, so it is not all that bad. But it is annoying that the scan function does not work. It does however monitor up to four frequencies simultaneously, and that is nice. The large bright screen is also nice and the buttons on the handset lets me control everything without toching the radio front.
After testing the radio for a month now I have the following pros and cons:
CON:
– Scan function does not work
– Signal detection weak. My Baofeng UV5R is better at triggering on detection of a carrier
– Fan does not always start until it is very warm
PRO:
– 4 channel standby
– Good screen and nice buttons
– Small size and rugged construction
– Good sound quality
– Good suppression of start/end-of-signal noise
Thanks for this and for reporting on the scan issue. I have heard of others having problems like this also. I agree, the quad-watch is a great advantage of this radio. Let me ask you something, you wrote “Signal detection weak. My Baofeng UV5R is better at triggering on detection of a carrier”. Would you say that the UV-5R has a more sensitive receiver? I have the “original” QYT KT-8900 (no “R” or “D”) and it is not that sensitive.
If only it had cross band repeat it would be a perfect little mobile repeater station. Then the lack of scan function wouldn’t be so bad. But alas.
I just bought one of these radios (7900) and I9 like it a lot except… it gets too HOT! This is acceptable in high pwr mode but it gets too hot in low pwr. I measured the low setting and it read 7.5W ! Anyone know how to adjust the low pwr to something more reasonable (1-3W)? A variable resistor adjustment? Set by software? Tnx WB8UCD Dave
Yes, I believe the handheld Baofeng UV5R is slightly more sensitive. Only my impression though, I haven’t really tested it properly. The sound quality of the QYT is better though, once you get signal detection.
good morning. It’s possible to increase range about 220 Mhz up 300Mhz?
I am not sure. If there is a way to do this, it should only be possible with the OEM software.
Many Thanks. Have you this sw? 73!!
Yes, it’s in the Downloads page here: https://www.hamradioreviews.eu/download/kt-7900d-and-kt-8900d-programming-software/ 73!
CHIRP v. 20170311 now supports the KT-7900D
Thanks, I posted this on Wednesday here: https://www.hamradioreviews.eu/2017/03/15/chirp-now-supports-qyt-kt-8900d/
How would you setup the KT-7900D to work with a digital 440 repeater using digital voice??
You can’t do this. You will need another radio that could repeat FM -> digital.
Yea… RX this QYT is poor… But TX its okay….
That’s a pity. I have the “first gen” QYT KT-8900 and it also suffers from bad RX.
I have this radio and the scan function does work, guessing you just got a junk radio.
can i connect two of them to use as a repeater to vhf? does anyone knows the connection?
you do need a license for this, correct?
Yes, this is not a license-free radio.
YOU CAN DO IT BY COMPUTER OR MANUAL
Is this a Quad Watch Radio?. As in it does listen to the other 3 Bands , the non active ones.
I herd 8900 is a Quad watch and this one is not. Can some one please comment.
It is quad-watch, at least according to the specs. The KT-8900 is the older model, which is *not* quad-watch, only dual-watch. Similar to a handheld Baofeng.
I got this Radio recently. I am unable to turn off the LCD. Its always ON. Even the back light for the speaker microphone does not go off.I tried menu option 8. ABR 0-50. Nothing seems to work
Even my Baofeng ,after few seonds in Idle the LCD Back light goes off.
Anyone else has this problem or is this just me?
Thanks 🙂
Same here, can’t find any info about it.
I cant get the lcd and mic light to turn off also, tried abr setting 1-10 still always on. Any help?
Mine isn’t quad watching. It will only RX on the channel currently selected. Is this a menu function Im not seeing?
Joel, It will quad watch. In the menu put it on the setting that has A+B+C+D
Quad watch really a nice feature. But Rx is poor, my experience is Rx comes in only when my adjacent iCom2300 has an S5 signal.
I bought this radio online bec i wanted the 240 & 350 band. But couldn’t get it to display itself. Seller not much help.
Hoping i can get some help here?
Thanks 73
