Marc- thank you for the input. I'll look for a 24/96 and see if I can
get one for her. She won't be back until next calendar year, so I
won't know until then if she is successful at getting any good recordings.
Noting that the 24/96 uses CF cards or microdrives, I think I'd prefer
to buy her CF cards to avoid moving parts (it is very humid and dirty
at the research site); can anyone tell me the maximum size CF card
that will work in the 24/96, and/or the minimum acceptable CF card
speed to avoid recording problems?
Many thanks,
Keith
