I am looking forward to it... ...just make sure all of that festive stuff does not effect the noise floor... ;) :D Btw, if possible there should be time allowed to one test within your intervals to reduce potential questions. For example, maybe the test is 90, 100, 110, then if one...
Wouldn't it be possible to just hold one tone (say 30hz) and move the other tone around (changing its frequency) and see which combinations give the highest level of IMD? PS This is really great stuff.
