Project Info

Another car radio for experiments with radio receiver for amateur radio/SWL etc... Car radios are usually well-made, with good sensivity, resonable selectivity and good mechanical construction (RF tuner screening for example).

I have problem with establishing what exactly model it was... There is only SONY logo and model probably was on sticker... maybe it is (or similiar) XR787 but that is no so important.

Components:

4052 - CMOS Analog switch [14]

4053 - CMOS Analog switch [13]

4081 - CMOS 4x2AND [12]

4558 - OP AMP [15]

5280 - ?

BA14741 - OP AMP [10]

BA3430 - Stereo pre-amplifiers with mute detection circuits for car stereos [9]

CXA1331 - DOLBY B/C TYPE NOISE REDUCTION SYSTEM [6]

LA1060 - Antenna Switching Diversity Circuit for Car-Use FM Tuners [2]

LA1137 - AM Tuners for Car Radios and Home Stereos [11]

LC7218 - PLL [7]

LC7582 - LCD driver [4]
