[Icom] Last Word on Internal Keying Relays (I hope...)

Mon, 25 Mar 2002 20:28:43 -0500

Steve and everyone else,
Why not just measure your voltage and current at the back of your amp and
see if it fits the specs of the transceiver?
I just put an Acom 2000A on line, which is very similar to the Alpha 91B,
only fully automatic and computer controlled, and I was very worried about
what would happen with direct connection to the IC 781.  I measured the amp,
it displayed 12 vdc at 1.6 mils and no problems.  I connected it directly to
the 781 and I am good to go.
I would not loose sleep over this issue if you measure it with a good Fluke
or similar meter.
73, Bruce K1XR
P.S.
Adam has always given me very sound advice over the years, he knows his
stuff.
