with the transmitter M708. The highly reliable transmission code ensures error-free signal detection even in presence of high noise conditions. Search of the station is possible in automatic or manual modes. The circuit can operate with a Digital or Linear AFT control. The Digital AFT mode is necessary for automatic search and requires an external circuit (TDA4433 or equivalent, e.g. dual comparator plus TV station detector) to convert the AFC-S-curve into an Up/Down command. Fine tuning (detuning) is also possible with different modes of operation. The circuit is assembled in 40-pindual in-li... |
