It is a sad duty to inform the ham community that Risto Vähäkangas OH8RV has been passed away and is a Silent Key now. Respect and my condolences. I'm sorry that i could not find a link to an official obituary. The link below is to The Finnish Radio Amateur association's weekly bulletin, where You can find the announcement of Risto's SK status. https://www.sral.fi/2021/02/05/bulletiini-05-2021/
