I wonder if you got a reply from someone that dont know what they're
talking about by the sounds of it. Heck, a small 2N2222A will switch the
load there with room to spare. Surely, they dont have the switching coming
straight off an IC? I dont have a schematic of it here to look at and see
what they've done, but that just dont sound right. Also, if it has an
actual internal relay, even a small reed type at that, it sould switch
that amount. When they said "either" 16 volts or 2 amps, but not both, is
a bunch of hogwash. It just sounds to me like a ploy to get around
warranty work no matter what!

Regarding my previous post in which I concluded that, according to the
specs in the Icom manual, the IC-718 doesn't need an amplifier keying
interface for the AL-811:
If one reads the specifications in the IC-718 manual, one would conclude
that the IC-718 does not need an external interface to handle the
AL-811's 12 volt DC at 100 ma keying line. Well hold the phone. I just
received email from an Icom technician who said that if I didn't use an
interface, it would damage the IC-718's send relay and that such damage
would not be covered under the Icom warranty.
When I asked how such damage could occur, given the specs in the manual,
the Icom technician told me that the specs as printed in the manual are
misleading and that the IC-718 send relay can only handle "16 volts OR 2
amps, not both."
Huh? That doesn't make any sense to me. None-the-less, given Icom's
attitude about whose fault it would be if the IC-718's send relay got
fried, I decided to invest in the relatively inexpensive insurance of an
ARB-704.
Thought you'd all like to know.
