Left it at 7 Mv/m but it's acting a little worse with RFCM changed. Check rest of driveline next maintenance.

Entry Makers: kernsBody: 

Tdeta all over with slight gradient changes and quenching with high CRFP when gradient changes made above 4 Mv/m. Replaced RFCM thinking it was a phase problem but it's acting the same as last controls and Tdeta and CRFP finicky and dropping cavity out with every small gradient change. Might be amp acting up but have plenty of drive and should be able to get more than 7 Mv/m.
