I was not at home when I heard this, but I did get a recording (a few of them). Signal was very weak on the PY2-81502 and PY2GN KiwiSDRs in Brazil.
2121 UTC-I was checking for Golden Oldies when I noticed someone in the Users list of the PY2-81502 KiwiSDR in Brazil listed as "oldiesRadio" (Pedro Velho, Brazil) tuned to 21485.10 kHz AMN. I tuned there and found a weak signal with severe drift and modulation issues.
2126 UTC-I think it was this time when the signal came back on after being off for a minute or so, this time with something that could actually be described as AM. At some point between 2126 UTC and 2142 UTC "oldiesRadio" started listening on the same frequency using the PY2GN KiwiSDR in Brazil
2127 UTC-I can hear some weak music coming through now on the PY2GN KiwiSDR
2142 UTC-Now "oldiesRadio" is listening on 15010.05 amn, but no signal heard there and "oldiesRadio" stopped listening less than a minute after tuning to that frequency
2155 UTC-Some time before now the station went off the air
Recording (the others were unusable):
