SMZ 1932 Sweden

The commercial weather station SMZ was on the amateur bands for a test.
Here is a proper QSL card from SMZ after a QSO with SM7NX (unlicensed).
This QSL is signed by Bengt Andersson who was the 1st operator at SMZ.
Miss Ellis Sandén, who was the 2nd operator at SMZ, was a member of SSA for two years 1932 - 1934 and got the SWL call SM7-088.

Notice what the operator wrote in the lower left corner: "SRI QRT" which I suppose means that the station had gone QRT but that he sent a QSL anyway.
