Power Output measurement #ubitxcw

Richard Pushman
 

Attached is a chart recording output power versus frequency at two different input voltages, 12.0 volts, and 14.0 volts.
I didn't measure current draw.

Output went thru a 30 dB attenuator into a Boonton RF Power Meter.  (e.g., a measurement or 10 dBm was recorded, then 30 added to it to account for the attenuator, then converted to watts - excel cell formula being "=(10^(G3/10))/1000". )

The switching points of the output filters are clearly visible.
