If you arent using a radio with a "waterfall" how do you know you are on center frequency with the other station? Lets have a look!

First of all I want to apologize for not being able to hear the "tone" that well in the video hopefully you can hear everything over headphones or if you crank up the volume. I couldnt figure out how to increase the volume of the "spot pitch" tone on the Elecraft K3S.

Also the K3S came out in 2015 I think mine is only a couple of years old, but what I meant is that the technology is really almost 20 year old technology.

Thanks for watching!
