[Elecraft] [K2] Interfacing a DTMF Pad

[Phil Kane]

I need to interface a DTMF pad to the mic input for special-purpose
signaling but  I have not yet found a desk mic that has DTMF capability
built-in. Has anyone had any experience doing  that?  If an external pad
is required (I have one floating around here somewhere), how can it be
done?    Will a simple Y connection suffice?
