I am having the same issue as well. I found a link in another feature directing everyone to portmon. I am running a 64 bit system so I am unable to do that. It took some time but I was able to get everything to work on windows 7 and linux except changing the frequency range. I used the settings QYT KT8900 and I think it may be a password issue with the radio itself. My manual states I can change the range without software. I have to press and hold the F button while I power up the radio. When I do that it brings up a prompt "passwd" It requires a 6 digit password and I have yet to figure it our or find anyone that know what that is.
I downloaded software from the link on where i bought the radio from amazon. https://s3.us-east-2.amazonaws.com/hesenatemobile/HESENATE+MT-225D+MT-225E+MT-250D+Software.rar This software allows for a password to be entered, but I cannot get it to connect to the radio. I can only assume it is also an issue with the password right now.

These ranges are what the radio supports for reception, not what the local band plan prescribes for transmit.
Many radios will limit the transmit frequency ranges to local laws; i.e. the radio will allow you to receive, but not to transmit outside preset limits. However, that's not true for some Chinese brands: here the operator must ensure that the radio is not doing anything outside allowed ranges.

Buenos días!!!. Para modificar el rango de frecuencias de la QYT KT-8900, jay que hacer lo siguiente....
Con la emisora apagada, mantenemos presionado tecla F mientras la encendemos. Saldrá un mensaje password, y con el teclado del micro, introducimos el valor 100120.
Luego, nos salen para poner 6 números, que sería el rango primero en VHF, por ejemplo, si queremos rango de 154MHz a 165MHz, pues introducimos 154165. Después, nos salen de nuevo 6 dígitos para introducir, que es el rango UHF, y lo mismo, primero frecuencia mínima, y luego máxima, por ejemplo de 430MHz a 470MHz, ponemos 430470. Y una vez puesto, la emisora arranca en ese nuevo rango de frecuencias. Arriba, hay un vídeo por si queda alguna duda.
