Dave,
There is no single answer to low power out on the K2.
The problem could be anywhere in the Transmit chain.
Turn to the Appendix E section on the manual and use the RF probe (parts
came with the K2 kit) to walk through the Transmit Signal Tracing steps
being diligent about the setup instructions.
The first test point where the RF Voltage is significantly lower than
the Expected value is the output of the problem stage.
Once that stage is located, we can help with detailed troubleshooting.
