http://www.ieee-pses.org/symposiumDave et al, If it was strictly sold as industrial test equipment then you could justify the 15.103 exemption, but it is advertised and sold for use by (us) ham radio operators, which is IMO is clearly not industrial nor commercial in that our stations are normally in the home. (But in my case its only in the car.) The good part is that the ham population drastically reduces the market for the device, so it isn't advertised to the general public. I suppose a comparison can be drawn to trade magazines with QST and other publications. Hams are expected to know something about interference/RFI. Arguably it is only operated by trained people since we have to prove proficiency in a written test. The device is for intermittant use, unless it lands in a factory where the application is industrial and nobody cares if it runs all day - as long as no RFI complaints arise. Otherwise, it'd be a bag of fun as a Subpart C+J project with requirements that conflict with the device's basic purpose. At the very least the digital related measurements are a good way to start, inhibiting or terminating the RF port then testing it as a Class B computer peripheral. Some user manual warnings regarding RFI potential should be added to the regular Class B warnings. Good luck!
