HAM3 ISI has more issues
I was working on FF on HAM2 and when I looked at HAM3 for comparison, I saw that the GS-13's have a 23 hz comb. My first thought was some vacuum component, but Kyle says he doesn't have anything running in the area. Near as I can tell it starts at about 9 am local on Friday. Unsure of the cause, but I need to run. I'll look some more tomorrow.

I was out last week but Gerardo did start a pump cart on Friday at the Diagonal OMC tube. Time? -> He shut it down this afternoon.
