I just bought the UHF version of this radio, and just now stumbled across this thread. Whilst I haven't received it yet, I have to say I looked high and low for a radio which equaled its feature set and was unable to find anything.
High on my list was the bandsplit: I need to cover frequencies at 411mhz and at 477mhz. While I will have to swap antennas to swap between these, at least at high power, having one radio is a plus.
I wasn't able to find ANY other commercial radios that cover this.
I have also had very good experiences with other, previously unheard of radios out of china. I purchased a few ultra-cheap UHF handhelds and have had no problems with them and they perform great.
If anybody can suggest another radio that can give me at least 410-480mhz bandsplit, CTCSS/DCS tones, narrow channel spacing, alphanumeric display and ANI, I'd consider getting it to compare the two. As it is, I've ordered this radio already (well, the UHF one). I will be happy to post a review when it arrives. If I have any problems, I'd also be happy to send it back and buy a more well-known brand.
Just for your information, I have done some digging thanks to the FCC registration information provided here and have come up with the real manufacturer of these radios.
Search here:
OET -- FCC ID Search
for T4K 5188U1
and you will find information on the original FCC testing by the original manufacturers, including images showing their brand: SoonTone.
Anyway I'll see how it goes when it arrives. Should be fun playing with it...
