[Elecraft] Amp keying circuit

[Earl]

Hi All:
I purchased the few parts to make up the amp keying kit and installed at J13 (K2).  When I key the transmitter, the relay will not switch in the amp. I can switch it by shorting the relay manually.
I measured the resistance while keying and it does not go to zero.  I have tried a couple of other 2N2222s which gives a lower resistance but I still cant get it to zero (in other words ground the relay contcact)  to switch the relay.  The amplifier relay runs 12V which is the stated upper limit of the keying circuit.

Any help would be appreciated,
