Q900 we introduced an ultra portable full range full mode SDR radio, we have developed the HAM-BOX phone APP mobile phone can easily control the radio and play, Make the radio operation more convenient and fast, the radio adopts a full keyboard design, built-in Bluetooth module, sound card module and communication serial port module.

We fully support the currently popular radio control software and logging software to give you more playable space. We have been working hard.
