µController Arduino - VHF Projects

Click to enlargeBausteine zum Selbstbau einfacher FM-Transceiver für den VHF- und UHF-Bereich durch DJ7OO
Ab und zu gibt es neu auf dem Markt erscheinende elektronische Bauelemente, an denen man kaum vorbeikommt. So ging es mir jedenfalls mit den FM-Transceiverbausteinen DRA-818V und DRA-818U der Firma DORJI aus dem südchinesischen Shenzhen.
To control the AD9850 you’ll need some sort of micro-controller.

For our local repeater ON0WV, I was looking out for a possibility to decode the assigned CTCSS tone (sent from 'friends'), and next to that, detect CTCSS from signals sent to other repeaters in the surrounding area, on same frequency (sent from 'foes').

Click to enlargeSimplex HAM Repeater Controller by ON7EQ
This project hereby presented is a complete HAM radio simplex 'smart' repeater, built around a Motorola GM-350/950, Arduino NANO board and a WINBOND audio recording integrated circuit.. The repeater was built to work on the 4m band, in order to promote activity and provide testing facility (by providing on-air S-reports).
