[Elecraft] SSB output overshoot

[Geoffrey Mackenzie-Kennedy]

Don,

Thank you for putting me straight on this. On the control loop question I 
agree with David, M0DHO, that an explanation of the workings of the ALC 
system would be useful not only in its dynamic state but also in its static 
state.

73,
