What version of lirc are you using?  What kernel version?  What config 
file?  I have a 311 that works for most part.  But ever so often it 
misses a digit in a channel, usually the first digit in a three digit 
number. Seems more times than not, it misses the number 1 in the first 
position.  The blaster I used is the second one on 
http://www.lirc.org/transmitters.html.  I tried tuning it, but still the 
same, I get about 2-5 misses a month or so.  I've though about using a 
hardware carrier transmitter, but haven't had the time, they are said to 
be more reliable.  The software carriers are affected by cpu load, 
interrupts and other things.  I have a dual core cpu now, it used to 
seem as if it was more reliable on the single core.
