[Elecraft] How to demo P3/K3?

[David Gilbert]

Baseband TV video is somewhere around 4 MHz, so I wonder if it would be 
possible to record some 80m activity using the video (yellow) input of a 
VCR or DVR, and then feed the recorded signal into the K3 at the 
hamfest.  You'd have to pay attention to signal levels ... it probably 
would require an RF preamp for the 80m feed to the VCR/DVR, and you'd 
probably need a bunch of attenuation between the VCR/DVR and the K3, but 
it might work.  I suspect you'd also get a lot of added noise ...

I've never tried any of that, but it popped into my mind as a 
possibility.  Maybe somebody here smarter than I can comment on its 
feasibility.
