The first power amplifier after the IFR function generator was saturation at an input of +13dBm.

- I reduced IFR from +13dBm to +10dBm to avoid saturation.
- I backed out all 3dB attenuators in the various feed lines.
- I added a 3-way power combiner in the the 9MHz line to the EOM.

This increased the drive to the 9MHz EOM by 10*log10(3)=4.77dB (compared to the original setting), or 1.77dB compared to yesterday's setting.

We now should have a 9MHz modulation index Gamma of about 0.17.
