Personally, I never got a basic transmitter of the type you describe 
to work 100% reliably. The unusually high frequency of the IR carrier 
in the Dish remote (56 kHz) combined with the pickiness of the Dish 
receiver leads to too much instability.

In the end, I had to go out any buy a USB-UIRT. This device has the 
advantage that it generates the carrier frequency itself, and 
therefore is not susceptible to the Linux box being interrupted 

I'm using the lircd.conf below. I had to adjust the frequency to 
45000 to get it to work reliably, and remove the NO_HEAD_REP flag to 
get it to work at all. You must use LIRC 0.8.1 or newer, because 
older versions don't have all the correct fixes.

Note that this config assumes a remote ID # of 1. If you have a 
second receiver, you would need the config for a different remote ID. 
I can give you #2 if you need it.
