CONNECTIONS
Refer to this diagram for connection details:
①
10.7MHz IF OUT with +/- 5MHz of bandwidth.
②
Headphone socket (3.5mm mono jack, also wired for stereo plug). When this socket is
used, any external speaker connected to socket (3) will be automatically disconnected.
③
External speaker socket (3.5mm mono). The speaker should have a nominal 8
Ω
impedance and power handling of 2 Watts or greater.
④
Accessory socket. Provides output for audio and discriminator, or other applications you
might create. Pin allocation as follows:
Values for pins 2, 6, 7 are for a 3kHz FM deviation at antenna input level.
