Froggy,

The high keying voltage and/or current on the amplifier's keying line
probably blew the reed relay in the Pro2's keying circuit.

1. Please refer to http://www.qsl.net/icom/auxrelay.html

2. Read Page 18 of your Pro2 User Manual 

The specifications for the internal SEND relay are 16 V DC 0.5 A. If this
level is exceeded, a large external relay (or external keying buffer) must
be used.

Cheers for now, 73,
