The 13:45 and 14:00 frames have a peak in the same place
as the 10:15 the previous day.

Such a small peak is mathematically insignificant though
but we might take it as a hint that a signal is lurking.

Edgar have you any way to check that the frequency is
properly locked to GPS?   If it's not locked the VO1NA
signal will be smeared out.
