Sony SW 100 microphonics, any cure??
 

Does anyone have a cure for Sony SW 100 microphonics? This causes the set to
shift frequency in response to physical acceleration. If you bump it while
listening to SSB or zero beating WWV you hear a warble. If you turn up the
volume loud while using the internal speaker the acoustic energy causes SSB to
sound really bad because the osc varies with volume. Headphones solves the
problem, but is there a real cure? I have checked 3 SW 100s and all had the
problem, some more some less.
