I should have posted this a while ago, so I apologize for not keeping everyone informed.
Essentially, I built a new machine and it has not been practical to leave it on for 16 hours/day to cover the 0700-2300L operations of SNA.
With that said, I'm currently going through my parts bin to build a dedicated 'Cheapo' feed machine.
Fear not, the random uptime/downtime is only temporary, and I actually have some new-and-improved Heliax cable to run from the antenna to further minimize loss.
I suspect all of this will be accomplished, and regular service restored within 2-3 weeks time.
Thanks for your patronage!
