yes, certification and verification differ. I had a re-look at FCC OET bulletin 62. The tuner may need certification if it is considered to be a peripheral to a computer, in this case a Flex Radio transceiver (particularly the ones without a front panel that require an external pc), depending on how it is interpreted wrt the radio/pc/amp/tuner setup.
But that wasn't the point. You guys were on the wrong track and shooting arrows at each other in the process. The tuner more than likely needs to be evaluated to Part 47 because it has a digital processor, not to Part 97.
