Doubler for 79.2MHz moved

Filberto, Daniel

We moved the doubler which drives the ALS fiber distribution box from rack ISC-R1 to ISC-R4. This hopefully reduces the electronics crosstalk between this unit and the PSL VCO. We als used a differemt RF patch panel in ISC-R2. The RF power levels have been re-measured, requiring to change the attenuator at the ALS fiber distribution chassis input from 1dB to 3dB.
