What surprised me:
He has a short antenna up, and the freq he was on was receiving some splatter from another station. He just grabbed the skirt of a filter in a window and moved it down a bit - splatter was gone!
It hit me while I watched the "spectral" window - I can use this thing as a test instrument!
Now, I'm all about setting at me desk slowly twisting the dial on a receiver - and there isn't much better than the smell of dust cooking on top of a 5U4 vacuum tube - but this was awesome. I was thinking - I've done a lot of microcontroller programming - maybe I can put a knob on an "L" bracket and every time the micro sees a pulse from the encoder, it sends a virtual "frequency- down - arrow." A real radio has knobs, after all.
