Yesterday I received my QSLs from Vlad for two contacts with him in Mayotte in Februdary 2019. The envelope sent from Russia was postmarked April 15, 2020. So even with the postal slow down from Covid-19 I still received the card in a little over 3 months. I have worked Vlad from several DX locations. He no longer uses LoTW but requests a quite reasonable payment via PayPal. His detailed instructions on his QRZ page. Every QSL request I have sent following his instructions has been answered.
