N1MM records QSO's where Writelog records continuously.
Using N1MM in the NA QSO Party, for 424 QSOs, I used 500 Mb.
A 25 second QSO took 1,101 KB Audio Format PCM 11.025, 16 Bit, Stereo.
With Writelog one hour (3582.78 seconds) is 6,998 KB Audio format MPEG
Layer-3 16 kBits/s, 11,025 Hz, Mono.
Quite possibly I could have cut down the audio format to something like PCM
8 kHz, 8 Bit, Mono 7 kb/sec. That would have saved about 4,000 KB. But
the 8 kHz quality was a fair amount less quality than the 11025 Hz in WPX
SSB using an IC-746 with fixed line output.
So I guess it depends on which program you are using to record, how much
quality you want and how big your hard drive is!

Is there an optimum setting for digital recording (bit rate?) that will
maximise memory capacity? I presume that ssb and cw being narrow audio
need <<than hi fi. Has anyone done the sums to record a 48 hour contest?
This would be brilliant for training.
Even better to record a segment of the band that can be replayed using LP
PAN etc. What memory capacity would be needed for that and is it
practical to do?

Thanks guys...I have Audacity, and that's what I was thinking of using
unless someone had a better idea.
I'm still wondering if there's a way to get the monitor audio out the
line-out output from the rear. It would be there out the headphone
jack but as K8DD pointed out, that is going to be controlled by the AF
Gain, which isn't optimal.
