I just looked at it. It looks real close to the box Globecast uses which is a SE830
Here is a pic of the Globecast receiver
Some of the stuff I googled mentions using Fortec Ultra software in it (not stock firmware..these were from hacker sites). If it can be loaded in there that would be able to use ChannelMaster
It sure is a spittin' image of it alright!! Go figure since it is a 'system' programmed for 97W. It makes you wonder if one of those 'other' files would work, then maybe it will work with channel master as it stands. I will keep looking around to see what I can find. Tnx. El_Viejo
