Recently I've build several FM broadcast band superheterodyne receivers
using e.g. NE602, SO42, A223D, uA3089PC ICs, ceramic filters and few coils. Now I am looking for similar project for AM broadcasting band. By "AM band" I mean both: Long Waves and Medium Waves. I prefer projects with stages on separate ICs/transistors (in opposition to "all in one chip" solution). First ferrite rod antenna, then mixer/oscillator stage (on IC or few transistors), ceramic filter, IF amplifier (on IC), AM demodulator and AF stage. I am looking for complete, tested solutions only (description, schematics, PCB). Do You know something worth of recommendation? |
