For the reception of Radio Frieloo on 6290 kHz I received a friendly QSL email from the operator. I sent my report to frieloo(at)outlook.com .

Radio Frieloo is a pirate station operating from the province Gelderland in The Netherlands. The operator told me that he is not often in the air. When it is the case it is mostly to test antenna designs. The transmitter is a R&S with 100 Watt as shown in the picture.
