Two quick technical questions about Marantz PMD670

["Desiree L. Narango" lilblue_frog]

For some reason, my the screen on my marantz has the am/pm flashing. The ti=
me is correct and is present on the file's data. Any idea why it's doing th=
is?

Also, in my recordings, I'm getting a higher freq. 'echo' from the bird son=
gs I'm recording (multiple copies of the spectrogram above the actual frequ=
ency recording is). Any idea why this might happen? It doesn't happen all t=
he time, but often when there is background noise. How might I avoid this?
