Hi folks, Our bare-metal prototype passed FCC Class B RE with flying colors; 8-12 dB margin.Now, a fairly similar unit (hey, they're prototypes) whose enclosure is power coated is now failing by 10-20 dB. The worst failures are at low frequencies, under 50 MHz, apparently. Is there anything more complicated we should look at apart from the powder coat mask not working well enough, such that covers and side panels aren't properly grounded with all that epoxy ? What else could account for this difference? thanks, Colorado Brian
