Just heard March conducting a radio check with Kingfish on 141.400 in AM mode. Might be worth monitoring this freq.

It's 01:00. I'm going to bed, but here's what I've heard since 22:57.

141.4 AM March GCA with radio checks (I couldn't hear who he was checking with).
Flight departures: 121.75 March ground > 127.65 March tower > 134.0 SoCal dep > 135.275 > Palm Springs A/D > 133.65 Joshua > Sundance (Fort Irwin), he didn't give a freq.

142.9 AM a/a
138.5 AM a/a
348.7 HIGH TEST

The flights leaving March sounded like DOGS call signs but I could never hear it clear enough to be certain.

Prior to take-off, a/c 2-3 aborted it's flight due to mechanical issues. Taxi'ed back to trouble shoot, I never heard anything after that.

Thought it was going to be more active than it's been.
