Ham Radio Power Chain: From Outlet to Antenna (

- I had recently messed up a calculation in a previous video so this video is here to fix that mistake. I also will show how efficient each part of a station is, and see how much watts there is at each part. Watch to learn more.

Well explained. I liked the practical application of Power Factor; Extra exam pool verified. Hmm, linear verse switching power converters....
I asked about this via email previously. Thanks for illustrating it and making it more understandable.
Thanks, Dave. Very interesting video. 73.
Excellent presentation!
Thanks for the correction. N0QFT
Good stuff.
It would be fascinating to see the thermal rise caused by 90W into a gallon of mineral oil.
Awesome job sir I enjoyed
Great demonstration...
Interesting test.
Oh. And in your receive, your power to the radio was greater than the VA to the power supply after the power factor.
Don't piss Dave off...he will stomp you
The radio is a 50 ohm radio. That 50 ohms is in series with your 50 ohm load. So if you have a 141.4v RF source and a 50 ohm output impedance in the radio, you will be dissipating 100 watts in your amplifier and 100 watts in the load. That's why your radio gets so hot. It's by design. It's not much better with a class C amplifier. But yes slightly. But it will still be over 200W dissipated by the radio.
