Recently I received a nice QSL and a friendly personal e-mail from Radio Pirana International. In October 2021 they were broadcasting from an unknown European location on 6330 kHz in Morse on 6330 kHz. The identification was broadcast continuously in that mode. See on: https://youtu.be/OTsMJCP4wxs. Whether there will be similar broadcasts is unknown, but keep an eye on their website: https://www.radiopirana.com/index.php/en/.
