POWER UP attempt - more luck in nominal lownoise
- To power to 30W, we turned off the 'BOOSTS' (FM5 in DHARD P&Y and FM3 in CHARD P, labeled 'boost10W').
- Turned ISS 2nd loop off and back on with AC coupling (ISS_ON).
- Stepped up to 30W nominal lownoise configuration.
- Stepped up the RP compensation gains to 1.6 at 30W (same sign as ASC control)
- We lost it on a simple SRC ASC yaw runaway (most likely SRC1 Y).
- We got a good range reading (with good calibration lines) at 25W - 85Mpc.
