In actuality...all the I-Pod does is play/record sound (and not very well due to
the frequency/tones of heartbeat & pulse)...so...the digital stethoscope is self
amplified and could operate without the I-Pod if I had a battery powered stand
alone speaker system I could plug into directly with the scope...or as you
suggested (great idea), a wireless transmitter that could then relay the signal
to a good powerful receiver. Any suggestions (brand/model) along either line?

Thanks again for this assistance!

William
