[Elecraft] KXPA100 not transmitting

[SAMUEL L ROWE]

Is anyone running a Elecraft KXPA100 amp with KXAT100 with a KX2 or KX3 that could help me with a little troubleshooting?

The power amp light blinks slowly (not on steady) and while turner tunes, the amp will not go to transmit but shows 25 W output.  I am using the KX2-controled connection.

My KX2 S# 01749 was new from Elecraft; the KXPA100 S# 1532 was acquired gently? used.
