TX Output Power

 

The  SKY-SDR  was designed to be a 5-Watt Output Power  QRP Transceiver.

It was designed to put out a little more than 5 Watts so that even with reduced power (i.e., 11 vdc), it will still be able to run 5 Watts.

 

CAUTION:  Do not run the radio at more than 5 Watts.  It's cooling was designed to safely handle 5 Watts.

 

 

OUTPUT POWER ADJUSTMENT:

 

The power must be adjusted separately on each band; the scale goes from 10 to 100.  I have measured it (below) in steps of 10 (i.e., 10, 20, 30, . . . 90, 100).  THIS SCALE DOES NOT REPRESENT PERCENTAGE.

 

Do not expect the output power to be the same on every band for any given setting.  It varies from band to band and must be adjusted by band.  Naturally it will vary with D.C. power applied to the radio.

 

The chart below shows the typical output power at 13.3 vdc (running from a battery).  It was measured on my own SKY-SDR (Serial Number 0001), using a Daiwa CN-101L, into a 50 Ohm dummy load.

 

This chart is just for approximate reference.  YOUR  MILEAGE  MAY  VARY!
