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. 73, Don W3FPR On 1/26/2013 7:21 AM, DaveVK wrote:
Hi folk, I've dusted off my K2 and decided to QRP OP on CW now the bands are up and running. The RX is perfect and filters alignments and freq cal is spot on, or near perfect. Since I've had this radio the Max power output on 20 - 10m has been well below 10watts. In fact I can only get 5 watts on 10m and about 10wats on 20m with the CAL CURRENT setting all the way up to 3.5amps. At 2.00 AMP setting the radio only puts out 3 watts. So something is amiss. I notice other people having the same issue and wonder if they ever got the issue fixed?
