Nice work!

I'm certainly interested in several.  Will it run from a wall wart or have a
built-in PS like the Monterey?

I'd try this mod, but I like my ESM1 - my soldering's not got enough to
handle the job, I'm afraid.  But I'll happily commit to whatever $75 will
eventually buy!

I'm assuming that there will be lots of interesting stuff that can be done
to analyze the signals once they've been captured to disk.
