Hi, having just purchased a 2009 Hunter
with a KVH M3 on board, I called tech support at KVH to see what the deal is with the old DirectTV M10 receivers and KVH M3 setups.
The tech guy, who was very helpful, told me,
To re activate the system, I would need to purchase
H24 receiver ($100)
D.C. Block splitter 19-0423 ($25), splits the signal between the old M10 controlling the antenna
and the new H24 for the programming.
KVH De stacker 19-0347 ($168)
Call Direct and activate the H24.
I would still be limited to SD,
But the system can be easily brought back to life for about $300
I haven't pulled the trigger yet as it seems the girl friend would rather have decent internet
and stream Netflix, so I might just save my money
for an upgraded data plan
