Hello.
I don't have the QYT KT8900 radio with 220Mhz yet, but I'm planning on getting one soon. This may help you a little, from my research the QYT KT8900 radio with 220Mhz is model QYT KT8900_R_ (note the "R" on the end). Also the Zastone MP-320 appears to be the exact same radio. These claim that they have a range of 240-260MHz, therefore they do NOT cover the US band of 222-225MHz.
I have found this, too, but haven't tried it yet: "Changing the 'PASSWORD' on these is supposed to change the range of the associated band coverage. I have been told to 'hold F and power on, get PASSWORD' and then you could use this to change the 'PASSWORD' which supposedly _actually changes the Rx/Tx range_." So that procedure could be used to change the "222MHz" range from 240-260 to 222-225MHz, /_*IF* it actually works that way!_//_ _/The filters in the QYT KT8900R may not be able to cover 222 though, they may be designed to just cover 240-260. Again, I have not tried this, I just found it on the internet.
I have the BTECH MINI UV-2501+220 (haven't tried it yet) and it appears to be the same thing also, except it comes already set up for 210-230MHz instead of 240-260. Maybe the filters are tuned a little differently?? Maybe something else is different also??
