Merv:
You are correct.
The PTT output from Penelope should be connected to "Bias Control",
which is PennyWhistle Pin 2
Ground from Penelope should be connected to Ground on PennyWhistle,
which is Pin 1.
The PTT output FET on the Penelope board is a 2N7002, which is the
surface mount version of the 2N7000.
I'll make the corrections in the next version of the PennyWhistle Manual.
