geldiev Hi, Marcologi!Try this diagram, but in russian internethttp://cxema.my1.ru/_pu/48/s13938695.jpghttp://el-shema.ru/publ/izmerenija/chastotomer_na_pic_kontrollere/8-1-0-234I think originally the scheme was designed specifically as a digital scale frequency for the radio. This is evidenced by subtracting intermediate frequency modes. Checking quartz resonators - is an added feature.
