[1000mp] pesky DIN plugs...

[lhlousek]

Are you guys talking about the 120VAC power cord or a 13.8VDC power cord.

I imagine an MP (not MkV) would draw around 2-3 Amps at 120VAC while
transmitting at full power.  A 14 AWG power cord should be more than adequate
for that.  At 13.8V it'd probably be closer to 18 A  and 14 AWG might be a
little on the light side.  Consider that the current limit for the wire is
determined by temp rise, the overall transmit duty cycle would significantly
reduce the temp rise in the wire. I would guess that 14AWG would be fine if the
rig isn't sensitive to the voltage drop caused by the wire.

An MkV might draw twice the line current but would still draw about the same DC
current since it runs at 2X the DC voltage.
