Description
What happened?
The "L RF XXX" CAT command is being acknowledged, but has no effect on the "RF Gain" slider of the "ANT" control. The "l RF XXX" CAT command does not report the RF gain as set on the RF Gain slider.
What did you expect?
The CAT commands should operate on the RF gain slider.
Steps to reproduce
Issue the two CAT commands.

Research direction
Start by reproducing the issue with the "L RF XXX" and "l RF XXX" CAT commands, then trace the CAT command handling and the ANT control's RF Gain slider. Done means setting RF gain through CAT moves the slider and querying it reports the slider's value for Hermes-Lite 2.
