The Peruvian stations are always nice to catch even with modest
antennas and equipments in Sourthern Finland.
This month´s catch is not a rare one anymore, obviously something happeded to it´s equipments this winter.It was not that easy earlier while the most common Latin station was Emisora Mariana de Bogotá.
After February Callao has been very easy to get at least a few moments during sunrise (around 03-05 utc. The station carries often sports with easy to recognize "Gool" announcements - actually it seems to have a long sports program daily before local midnight. It should have close down around 05 utc but I have never managed to hear that.
What is very clear in this time with modern Spectrum receivers you can easily see the carriers of the stations and while Mariana is very stable at 1400.00 and CBC at 1400.009 Callao is clearly lower on 1399.996, so especially checking recordings afterwards you can note what is dominating and check the audio after that... The figure shows a typical morning with 2-3 stations (here Bogotá, CBC and Callao at the same time).
