100 watts vs. 5 watts: Can you hear the difference?
In this video, I transmit at 5 different power levels, from 100 watts down to 1 watt. I record the audio from a station listening to my signal 250 miles away.
In this video, I show an example of transmitting SSB at 100 watts and then turning down the power while listening to the results. A nice ham (Bryan, WZ5DX) gave me some audio feedback from 466 miles away. I also discuss some philosophical concepts about QRP and the unreliable nature of propagation that makes it hard to predict where your signal will be strong on any given day.
Thanks to Stanley vk3bot for sending this information!
Here https://youtu.be/rkM5VIEYqe4?si=ASUCS-l1hpzXDeMB is part 1. This concerns CW.
Whilst it in interesting, I think part to is more relevant to us on HF SSB. And the really important part, especially to those of us in FAMPARC local noise, the noise floor is the all important part. My noise floor here is around S9 pr worse. When I go camping it would be S1 maybe.
Quite interesting. Thanks Stan
