[mythtv-users] controlling a dishnetwork receiver

I have seen several people report trouble in building the amplified 
transmitter.  I have personally built several of the 'simple 
transmitters' which have worked flawlessly for me.  I may be wrong, but 
the only downside I could see to the 'simple transmitter' is its range.  
Typically I get less than 3 feet, depending n the receiver.  For me, 
range doesnt matter because I have my transmitter mounted about 1 inch 
in front of my cable box.  Take a look at the transmitters I built:

PS: I still have a few extra of these.  If you dont want to build your 
own, I can send you one for $20 shipped.
