Getting a KXPA100 to work with a KX2

[Peter Pauly]

I just finished putting together a KXPA100 with ATU.  I've got the KX2
connected to it via a KXPACBL connected to the accessory jack on the KX2
and the CAT5 cable on the amp. The smaller GPIO plug is unconnected. Also
the BNC of the KX2 is connected to the RF IN on the amp. I put the KX2 in
PA Mode YES and can dial up the power to 100 Watts on the KX2.  KX2 mode is
CW. KXPA100 is in Auto ATU mode, ANT 1.

The transmit light on the KXPA100 never comes on.

If I hit the Tune button on the KX2, it shows at solid 25 Power Out LED and
a 1 SWR LED.
If I hit the XMIT button on the KX2, nothing happens on the KXPA100.
If I hit the Tune button on the button on the KXPA100, I get a flashing 25
LED (SWR?) on both a known good antenna and a 50 ohm dummy load.

Any suggestions before I contact Elecraft technical support?

The Y adapter was the part I didn't have correct. Thanks Richard, it's
working now.
