Ray, K2ULR, mentioned to me that VCR's probably use the sync pulses of a normal baseband video signal to sync the rotating heads, which would make them unusable for recording simple RF. A DVR might not have that problem, although noise and signal levels could still be an issue. It might also be the case that any standard video recorder (or at least the software associated with it) might try to insert sync pulses on playback.
I've seen USB video capture devices for $20 or less, but none seem to have a port for playback. I'm pretty certain that many of the PCI card versions do, though. Of course, it would always be possible to build a simple mixer that shifted a ham band down to lower than 200 Khz and record that with a decent computer sound card, and then mix it back up to feed it into the K3. 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.
