But camera experiment \r\ncontinues and is integrated in some pocked qubes of colleagues from EA. \r\nSo if your mode will be available, we can implement it in the new \r\nfirmware versions. So keep us informed.\r\n\r\n 73! de Tomas OK2PNQ\r\n\r\nDne 08/09/2022 v 19:46 Sasha Tim napsal(a):\r\n> Thank you very much everyone!
