I have owned the KG-UV920R for about three months now, so far I'm pretty happy with it.
It has X band repeat, CTCSS, DTMF, basically everything you'd expect from a dual bander except for a data port (no echolink interface).
The VK model does not have an expanded RX range for scanning or AM RX, it only includes FM broadcast radio (why?).
PRO's:
-Power output is spot on for HI, MID, and LOW on both bands, and doesn't vary after heavy use.
-Fan is quiet as a mouse and still performs well.
-Audio on TX and RX is fantastic.
-Comes with a remote head kit (and if you've got a RJ45 crimping tool you can make custom length cables for it).
-Faceplate can be mounted flat or angled up.
-Good channel storage (1000).
-Reasonable price (In AUS all radio's are about 30% more expensive than anywhere else on earth!).
-Very solid body construction.
-Fully controllable from the DTMF mic.
-PC software is relatively easy to use.
CON's:
-Front VFO/Channel selector knob changes channel even if you don't turn it. Just a touch on the dial and it'll randomly go up or down. I use the mic for this now.
-Current version of programming software will not let you save your settings to hard drive (wouxun assure me they are working on the bug fixes)
-Suffers badly from front end overload, at least at my QTH.(In Sydney there are 7 narrowband broadcasting stations on 151-2 MHz within 2 miles of me). This is not a problem on UHF though. Otherwise the intermod rejection is pretty good.
-Programming a channel on the front panel takes quite a while to master.
Summary:
I bought this to be a cheap dual bander which I can bash about in the car.
What I received was a cheap dual bander which I can bash about in the car.
It does the job, gets good reports, and hasn't had a problem with the hot car or vibration. Power output is stable and bang on, everything works as it should (except the VFO dial).
If I had to buy another rig for a second car I'd think about Alinco though.
