I have an almost identical setup, but I'm using two homebrew LIRC
simple transmitters wired in parallel, so each Dish receiver has it's
own transmitter. I'm not sure how much the improved transmitter
costs, but it was only a couple bucks for an additional IR LED at
Radio Shack and it works great.
And just out of curiosity, were you able to use the IR9 codes as-is?
For some reason, they didn't work for me. I ended up having to
translate them to "RAW" codes...
