I think, that Supermax FT9800S is rare receiver, and it is difficult to find support for it. the links in it's official site are not working, and no support or information on how to do it's software upgrade.
the other problem is that I decided to upgrade software, to unlock channels, but I don't know exactly how and what to do. www.newprog.net has some archives, containing software for Supermax receivers, but there is no step-by-step explanation on how to do the upgrade.
so, please, could anybody explain, how to do, and what to do?
because, as I see, just connecting the receiver to the COMport of PC and running the program is not enough. there is smthng more...
thanks to all for attention
