[Elecraft] I cannot TX with Heil connected in the back of the K3

[Ed K1EP]

Hi Jorge - The PTT should not have anything to do 
with where your mic is connected.  If you get an 
ERR PTT that means that when the radio is turned 
on, the PTT has been applied.  There are at least 
five ways to engage the PTT as far as I recall: 
TX button on front panel, PTT line on front mic 
connector, PTT jack in rear, RS-232 pin, and 
through software.  I suggest checking/removing 
each of these to make sure that one of them is 
not shorted.  I think that the Heil footswitch 
has multiple switches on it for sequencing so 
maybe you have it wired incorrectly.
