Also, in order to get output on CW I have to send a series of dots or dashes to get the relay to trip.

And, that at full output, you can only expect the typical analog meter to read 25 or 30 watts maximum for 100 watts PEP, unless it circuitry to read peak envelope power. Do you have a separate general coverage receiver? If so, you can listen for both the USB/LSB/CW carrier oscillators and the modulated signal.
