The problem with adding remote control is you have to continuously power
the receiver for it in the auto recorder. This will way shorten the life
of the batteries. Normally that unit is only running the timer in the
off intervals and that's extremely low power. For equipment like this it
could be on the other side of the state, hundreds of miles away and a
ways off in the brush/swamps/etc., so limiting trips is very valuable.
You want long service intervals.
Note this is a recorder intended for scientific survey use. Before
starting the survey you come up with a protocol that specifies the
record intervals. You don't change them during the middle of the survey
or your data is compromised for some uses. And you'd probably not pass
peer review for publishing. Changing protocol on a scientific study is
not done lightly.
I like the idea of this unit, though I'd really prefer compact flash
instead of SD. I have both cards, but SD is easier to misplace. It also
would have been nice if the unit had phantom power or plug in power.
You don't have hours of recordings exactly in typical froglogger use.
Generally they record just a few minutes several times a night. They are
not run continuously. Over the course of months that can add up, of
course. Thus the advent of computer sound recognition analysis.
I'm waiting to see what the froglogger group comes up with, but probably
going to get a logger or two. I'd love to have a dozen or more, but
that's too much money for me.
On the amphibulator that was mentioned, the pdf has to be bought from
IEEE. Won't help a whole lot, the concept is described but not enough to
build one. Sounds very similar to what the froglogger folks are building
for their next model. The froglogger that's current requires a Marantz
660 for each logger, making it quite expensive. That's one of the
advantages of the Song Meter, it's complete as it comes.
