[GreenKeys] HAL ST-6 - squelch?

[tony.podrasky]

GM OMs;

There is an adjustment to the MARK "hold" function AUTO / AUTO OFF.
You adjust it for how much noise / how little noise you want to allow
before the machine's RECEIVE lamp illuminates and it tries to print
something.

If you set it too tight, you'll have to be spot-on with the mark, which
doesn't work very well when you are doing a round-table QSO (not
everyone is zero beat).

If you set it too loose, you'll get random characters / noise tripping it.
