SD722 advantage

["David Martin"]

Until recently I have been unable to record in some local areas near radio=

broadcasting towers because of interference -- I would always get a low
level of music in the background.  I could never solve the problem.  I
checked cable wiring and upgraded cables, used different mics (Telingas and=

Sennheisers) and used two different recorders (an old SONY cassette
recorder and a PMD670).  Recently I started recording with an SD722 and --=

presto -- no interference.  Same cable and mics.  Of course, I don't know
why the 722 is better, but I suspect that the metal case helps by shielding=

the electronics.
