I think most of you sussed it, but in case you didn't, here's the

Over the past few nights I've been monitoring 1470 kHz using audio 
analysis to "watch" the various carriers fade-in, sign-off or 
fade-out. It's a very busy channel with many carriers slightly offset 
from each other.

Fade-in has been as early as 2130 when only Brazil or Argentina is 
realistically possible, and mostly the strongest signal has been CPN, 
Lima, Peru peaking 0300-0330 UTC.

Does anyone have a list of Brazilian MW stations with sign-off times? 
Or in fact other South American countries too ...

I've uploaded the spectral traces onto my website (CORRECTED and checked)
http://www.dxradio.co.uk/mwoffsets/index.html

The rig is a AOR 7030+, with a 40-inch square MW loop, and the audio 
analysis is done using Spectrum Lab. I've tuned to 1469.000 kHz in 
usb and analysed the audio from 925-1075 Hz ... 1000 Hz would 
correspond to a zero Hz offset on 1470.000 kHz obviously.

CPN Lima would appear to be the station registering on 995 Hz on the 
scale, ie 1469.995 kHz given its fade-in time and peak.
