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:
?

40m? ? ? ? ? ? 2.8w? ? ? ? ? ? ? ? ? ?3w
20m? ? ? ? ? ? 2.4w? ? ? ? ? ? ? ? ? ?3w
17m? ? ? ? ? ? 2.8w? ? ? ? ? ? ? ? ? ?3w
15m? ? ? ? ? ? 2.2w? ? ? ? ? ? ? ? ? ?3w
10m? ? ? ? ? ? 1.25w? ? ? ? ? ? ? ? ?2w

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