[1000mp] Mark V ALC Reading

[GMDX]

Hi All
Hello John W3ULS
                                   I also had the same conversation with
Yaesu here in the UK as previously I owned a Kenwood when on cw you adjusted
the ALC. They tod me at Yaesu that the ALC on the rig had no bairing on CW
it is only for SSB .
