EAR185 1932 Spain

EAR 185 (Sr. Edmundo Mairlot, EA1AS after EAR conversion on 1934 to EA callsings) qsl addressed to W2BKT (Charles W. Watson, Union City, NJ) confirming qso on january 1932, and a letter addresed also to this station W2BKT.

I supose that EAR 185, one of the most active EAR station that years, following his qso logbook addressed to all USA stations, these letters requesting help and reports for the inminent solar eclipse in that year (not sure but I think the eclipse was august 1932).

The idea was to stude and analize the impact of a complete solar eclipse in the ionospheric comunications, there must be one of the first amateur analisys on that phenomenal.

The amateur bands used were 14 mhz with normal conditions between EA, EU and USA and 7 mhz, when dark area of the eclispe cross the Atlantic ocean.

I think that some articles were published on QST that years.

Thats all, the letter explains itselves.
