It does seem that the fluctuations in the output power meter readings are an artefact of the sampling/averaging process that drives the meter display. I will have a play with the multimeter options to see if there is a setting which provides a more meaningful result when sending CW. 73, Brian VK3MI ZL1AZE -----Original Message----- From: Tim Ellison, W4TME Sent: Tuesday, February 14, 2012 3:38 AM To: Jim Jannuzzo Cc: [email protected] ; [email protected] Subject: Re: [Flexradio] FLEX-3000 FLUCTUATING CW OUTPUT POWER You can try lowering those time values and see what happens.
