March 2021 South American Ultralight DXpedition by Martin Butera

Gary DeBock

Ultralight radio DXer Martin Butera (an Argentinian currently living in Brasilia, Brazil) has shared with me the results of his amazing portable DXpedition to Rio de Janeiro, Brazil in March of this year, using only a Radiwow R-108 Ultralight radio with the internal loopstick. These loggings should be useful for anyone with interest in South American DX!    

Martín Butera uses the following names here: A) Excellent (B) Good (C) Fair (D) Poor
It's understood as: A_ Excellent (when the signal is very strong and there is practically no interference)
B_ Good (This indicates that Martín was able to hear the station well, but maybe there was interference, noise, or fading).
C_ Fair (There was interference and / or fading or noise that made copying difficult, but he could still understand parts of the program. Enough for a positive identification)
D_ Poor. (It was almost impossible to copy the signal but you could hear some content. Enough to make a tentative identification).
We also mention that the receptions do not have a specific date of the day because it is a weekly period that goes from March 1 to 8, 2021, to be on this list, it means that at least they were heard more than 2 times, all with their corresponding IDs.
