[ICOM] 756pro

[Larry Winslow]

Don't know about the SB-230 but all of the other 
Heath amplifiers have 100+ volts on the key line. 
This is way beyond the capability of the Icom rigs to handle.

I suspect you've blown the keying transistor 
within your rig. Plus you need to get an 
interface. Their simple to build and/or cheap to buy.
