John Kirk Sorry- EMC- Electromagnetic Compatibility- generic term for various European Commission Directives defining, among other things, permitted emission and susceptibility to emissions for electronic equipment- I believe the standards are not dissimilar to UL/TUV/VDE etc, and are designed to stop equipment being affected or affecting the operation of other equipment. Testing, or more accurately, a Certificate of compliance with these standards is required for equipment sold in the European Union, with various penalties for non-compliance, including seizure of goods etc etc There are "EMC clubs" in the UK, set up by the Department of Trade and Industry, but I'm not sure what they actually do... and I presumed other PIC users in the EU might have had similar experiences and found solutions.
