Dave - The THP amp probably needs a TTL input. While the K3 has the same
band data output as Yaesu, the K3 output is open-drath whereas the Yaesu
output is TTL. Unless the THP amp has internal pull-up resistors on the
band data input, you will need to add pull-up resistors to 5VDC to drive the
THP amp band data inputs.
