I'm not so much convinced of this testing method, comparing procedure and
final conclusions.
SWR changes replacing coil the tranformer core material only show that one
of the 2 wasn't done correctly.
1) A measure the beverage self impedance and terminate it properly.
2) Prepare a transformer with a right step up impedance.
3) Check the transformer on the 50 Ohm side and the proper resistive load on
the other side.
4) Verify the useable transformer range varying applyed frequency.
Use the beverage and don't care about its response to unwanted modes or
unknown sources in respect to other beverages with different headings.
