A simple brute force test would be to procure a simple mild steel box sufficient to contain the K2 on all sides save the front panel. See if the K2 in the box is still sensitive to nearby power fields. If not then proceed to use less shielding in a series of tests:
Experiment with sheets of steel to cover just the bottom of the radio, one or both sides, etc. to effect the simplest shield arrangement. Foil shielding tapes are available, and could be used to fashion smaller shields as needed. Perhaps only shielding the areas of circuit involved with frequency generation by under board added steel ground plane will be sufficient. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
