[Elecraft] [K3] using a footswitch for PTT

[John Shadle]

Hi all,
I am finally getting the ol' radio back up and running after a few months
of packing and moving from NC to WI. In my past life (in NC) I was mostly
CW, but now that the shack is in the basement I want to get back on SSB.

I have an Elecraft desk mic (the Heil version from a few years ago). It has
an input for a 1/4" footswitch controller for PTT. I've never used a
footswitch before, so this is all new to me.

I don't have a Heil footswitch, but do have an older Yamaha foot pedal
which I picked up at a yard sale a couple of years ago. It creates a closed
circuit whenever I depress the switch (and is open otherwise). The odd
thing is that whenever I plug in this footswitch, the PTT is engaged when
the switch is plugged in--and the PTT is disengaged when I depress the
switch. This seems like odd behavior to me. Is there something in the menu
that I need to change? Advanced mic parameters? I'm kinda lost.

I cracked the case open to view the innards, but it's just two wires (tip
and ground for the 1/4" cable) and a switch. I don't think there's anything
I can do in there to modify things.

The model appears to be a Yamaha FC5 (

although I can't find a model number on it.

Thanks!
