Yup. There are dozens of little recorders that work well for making continuous recordings, I've been using a Roland R09 that I've had for many years.

If I want to go to the trouble, I chop up the recording into one hour files using the wonderful MP3DirectCut, which is extremely fast at that task because it doesn't do any re-encoding - it merely cuts on MP3 frame boundaries, and creates the proper header info for each file.

I was interested in the OP's suggestion because it purports to make one hour recordings on the fly, which would save that step, and also be a safer way to do a whole contest without having to worry about a glitch in hour 47 that ruins the whole file.

I use a Sony ICD-UX560 Its MP3 files names are just numbers with an underscore which are easy to transfer to a PC. It is a tiny 2oz device that takes almost no operating space and it works quite well.

There was one comment on Amazon complaining about the file naming by
this recorder - that after some number of 1 hour files, characters not
allowed by Windows started appearing in new file names (<, ?, etc.).

That would be a fatal flaw of course.

What do the file names look like in your experience when you plug the SD
card into a PC? Easily identifiable by hour? Have you tried recording
for 48 hours?

Thanks,

Someone asked about recording off the air. Outside of using a PC and associated resources here is an excellent device that is inexpensive and works extremely well.

It records 1 hour segments and clock can be set to UTC time. Fast forward and reverse and a over one thousand hours recording on a 16Gb memory card using 64kbs bitrate. It goes up to 192kbs for high quality recording. Internal mic, external mic and line in connections. Analog and digital output. Very cool. works extremely well and very easy to use.
