[Kenwood] TS590SG ALC Flucuations

[Steve London]

Check that the carrier level is up high enough, and not at the lower edge where 
power may start to be cut back.

Also, check the power supply voltage at the TS-590S molex connector to make sure 
it isn't drifting down.

Might also post this on the TS-590 groups.io.
