ESC - Feedback

Not sure if or when Flex ESC will work well or not, but in general using other radios and/or external units, the key is to design a good noise capture antenna. One that targets the offending noise source. The actual configuration of this noise capture antenna takes time and effort. A lot of design work and experimentation. People that don't do the ant design work, tend to complain that the phasing and noise canceling doesn't work well. But, it does work well in most cases if the noise capture antennas is planned and implemented well. Designing a noise capture antenna is like the opposite of designing a good RX antenna for max S//N.

@Trucker Dunno. I thought I wanted a noise antenna, a 'lousy' antenna — that is, I want it to pick up very little signal, just noise, so that its input can be more-easily subtracted from the actual listening antenna. But now I'm wondering if that's not how ESC actually works, b/c I plonked a fairly short vertical antenna 5' from my (presumably relatively noisy) IT rack and despite much spinnin' of the ESC knobs, I have not yet achieved grinnin'. I thought somebody had linked or posted an official FRS video demonstrating ESC doing the thing, but I can't seem to lay hands on it at the moment. Maybe over the holidays I can put up the vertical outside the house at different/greater lengths, see if I get different results.
