The third harmonic of the 8.362 MHz crystal is exactly half of the frequency of interest and mixes with the incoming rf to give a baseband output to the crystal earpiece... Google "polyakov direct conversion receiver" to learn more... <br />8.362Calvinhttps://www.blogger.com/profile/04642066772718060779noreply@blogger.comtag:blogger.com,1999:blog-7967082143331094697.post-3120391108635904132018-12-26T14:08:50.949-08:002018-12-26T14:08:50.949-08:00what is the function of the two diodes back to bac...what is the function of the two diodes back to back?coffeeCup9NZhttps://www.blogger.com/profile/12173463517320529773noreply@blogger.com
