Eski PCI TV kartı ile FM PLL Stereo alıcı yapımı

Öncelikle belirtmek isterimki bu konuda ilham aldığım projeler Zekeria beyin geniş bant alıcı ve Hüseyin GUNER beyin TSA lı prejeleridir. Azcık ondan azcık bundan karma bişeler yaparak ortaya güzel bir sonuç olarak FM PLL STEREO alıcımız çıktı.

devremizi kurduktan sonra TV kartından söktüğümüz tunerdeki 4mhz kristali sökerek yerine 6.4mhz takıyoruz ve 16F628A programındaki adımların 100khz olmasını sağlıyoruz.Son açılan kanal eprooma kaydedilerek hafızaya alınır.Stereo decoder olarak NEC 1026C kullanıldı ve ledi optokuplor ile sürerek pic stereo yazırmak için input edildi.

Gerekli malzemeler:

Eski bir PCI TV kartı tüneri
6.4MHZ kristal
Pic yüklemek için gerekenler
16F628A ve gerekli devre
Biraz lehimleme kabileyeti
Biraz hayal gücü ve heves

kolay gelsin..

Sanırım hatasız çizebilmişimdir.Stereo decoder seması
