Austro Control sent a nice fullly detailed I got my QSL NDB GRZ-290 via . The beacon was located on Graz Airport in Austria.

Fully detailed eQSL from Austro Control for NDB GRZ-290 Graz

And yes: “was located”. Because this is another NDB that can’t be heard anymore. More and more of them are taken out of service, as they are deemed obsolete as modern VOR and GPS systems are now available to support navigation.

NDB GRZ was taken off the air on September 7th, 2023. Fortunately I still had a Pskov recording from its final month of operation. I guess I better hurry to get my other Austrian NDBs QSLed.
