Hello Mohammad: I guess a out-of-tree module is not installed (probably gr-dab, as the missing blocks are related to dab).
You can install it by yourself, but I think gr-dab does not support 3.10 yet (and is not actively being updated). There's some 3.9 ports, though. https://github.com/andrmuel/gr-dab/issues/28 Regards, Kyeong Su Shin ________________________________ 보낸 사람: Mohammad Riyazudeen <[email protected]> 대신 Discuss-gnuradio <[email protected]> 보낸 날짜: 2022년 5월 28일 토요일 오후 4:27 받는 사람: [email protected] <[email protected]> 제목: Missing Block Dear Experts, The file was designed in GNU Radio version 3.7, when I tried to open it in GNU Radio version 3.10 there was an error in the Blocks like "Missing Block" . What is the issue, how to recover the Blocks. Please refer the attached screenshot. Thanks Mohammad Riyazudeen
