I noticed the K2 preamp is off, so that makes the background quieter, but I can't tell how the KX3 is set up. Does the KX3 have the optional 'roofing filter?' Also, you really need to do something about that REALLY LOUD CLACK at 0:19 which occurs when everything else is quiet. I probably ruined my speakers from it.
This doesn't show much of anything. I would need to have the filters, RF gain etc set exactly the same. I have over 50 years experience as a ham and 40 as an RF engineer. All these rigs work well, put your dough into antennas if you want to be successful.
