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. 73, Dave AB7E On 8/9/2010 6:11 AM, Randy Moore wrote: > Looks like we may have someone bring a P3 to demo at the Huntsville (AL) > Hamfest.
