I have two Heathkit electronic? keyers and wonder if they can be used on the QCX. I ask because it will work on my Heathkit SB 104a and Kenwood TS 820s but will not work on my Icom 740. The Icom takes a three way plug for use or a straight key or paddle style key but will not work if I try the electronic keyer using straight key contacts. Icom has iambic hardware installed. I can't test yet because my kit is on order. Thanks Carl
