Hello everyone. I haven't gotten around to installing the updated Si4732 receiver board into the Quansheng UV-K5 station for a long time. And now I've finally decided to do it, but I didn't want to just replace the old board with a new one, so I decided to install the new board into the new station to eventually compare the operation of the old version and the new one. See the video for the results. 00:00 Introduction 04:51 Sensitivity measurement 09:09 Board installation work 26:25 Test of work Telegram channel - https://t.me/r3mdg Let me remind you that the content can be found on the Rutube platforms - https://rutube.ru/u/r3mdg/ VK video - https://vk.com/video/playlist/1700112...
