If you are lucky enough to have ANY software for this radio, then you are VERY lucky.
HYT, BLACBOX, HYTRA, TEKK and a couple of others ONLY allow for a limited version of software and it only allows for changing frequency's.
If you think you need to update firmware or you need ANY TYPE of service that will adjust frequency alignment or audio adjustments, then you have to send it one of only two locations to have all this done.
With some of these radios, it is more cost effective to throw them away and buy a new one as most of the service starts at $80.00 PER RADIO p;us yaour shipping.
My take is stay with Icom, Kenwood, Motorola and forget the others.
