I've heard that the video link needs ~14MHz of bandwidth, yet Wikipedia
says the PAL and NTSC signals only use roughly 4 to 5MHz of bandwidth, and that's for 625 lines. I'm wondering if 18MHz is overkill? Maybe we could get by with less bandwidth for our 520 line FPV cameras?
Hypothetically, a 15MHz or even 8MHz SAW, it might make a replacement mod worthwhile IF we had a quiet flying site, and the signal was usable. Before I waste my time chasing down unobtanium parts, can you suggest what the outcome might be if we did
use a SAW filter that was too narrow? Could we get better range at the expense of video quality, or am I over simplifying things?
