In testing the linear vs. switching power supply consumption I determined the following standby power draws:
- Astron RS-35M: 25 watts/hour; 600 watts a day
- Powerwerx SS-30DV: 5 watts/hour: 120 watts a day
- Kenwood TM-D710G: 15 watts/hour: 360 watts a day
- Elecraft K3S: 33 watts/hour: 792 watts a day
- Icom IC-9700: 22 watts/hour: 528 watts a day
It wasn’t unusual for me to have the Astron, Elecraft, and Kenwood powered on 24 hours a day, for many days a year (likely about 200), which is 1.75 KHW/day, or about $88 a year and going up!
