Card from Double Kilo (Korenklopper) Radio

I received an email confirmation and this nice sticker from Korenklopper Radio for my reception Saturday night on 6306 kHz (my first time hearing him).

According to the operator, "Koren" is corn and "klopper" is "to knock with a hammer".  On shortwave, however, he announced as "Double Kilo Radio".

Thanks Korenklopper!

Cheers, Terry
