exchanged the 500ft spool by a shorter cable to get more range (but less resolution).
Due to the lower losses of the cable i also removed the 2W amplifier.
Right now both cavities can't be locked at the same time, they are slightly out of range.
RCAV is resonant at 0.1958 for the slow actuator, ACAV is resonant at 0.1930
max range for VCO is reached at 0.1948
i've changed the RCAV settemp a little bit and will keep an eye on that and we will hopefully be back online tonight
