You will get 5w if your power supply holds to 8.4 volts o transmit? i can see from your readings that the dc supply is dipping to 6.8v on transmit. This indicates that the power supply is current starved

What are other seeing with the power levels? I have a QRP Labs dummy load that I connect my volt meter to get a peak voltage reading.?
The voltage on the radio is 7.7v, drops down to about 6.8-6.9v when tx. The Driver is set to 100 on all of the tests, and the mode was 2TONE.
When I tx into the dummy load. Based on the calculation its showing I'm outputting about:

I'm thinking that's on the lower power levels than I would have expected. Are others seeing the same thing ??
