[Elecraft] FT897D and KPA500

[David Mitchell]

I am having difficulties keying my KPA500 from my Yaesu FT897D.  It has no
dedicated PA Out jack. The CAT/Linear jack is currently in use transmitting
band data to the RS-232 port on my computer and I had hoped to use the ACC
jack to key the amp.

I can get a connection for ALC voltage through the tip of that stereo
connector, but the ring wants to be brought to ground to transmit.  I have
a Quicksilver "Tune-Rite" that does just that and if I connect the amp PA
key and the Tune Rite using a "Y" connector the amp keys fine, but I can't
key it from the rig itself since the PA input wants to be brought to ground
to transmit.

Any creative suggestions on how to get a PA key output from my FT897 are
appreciated.
