Category: Inside Circuits Views: 5006 Rank: 10 This AM receiver is working perfectly without the need of coils or even a variable capacitor. The LF356 is the basic component. P1 and P2 are the frequency selectors. Use a small telescopic antenna. The stations selectivity is not perfect but is acceptable.  This circuit can be very small and you can power the circuit with a 9 volt battery. Datasheet file1: Click here to download BAT85.pdf datasheet.

The TDA7000 is used for its mixer and L.O. section. Using a dual op amp driving a rectifier and emitter-follower, this circuit indicates ac current on an LED. Ll is an au NiCad Charger with temp control One way to charge Ni-Cad batteries rapidly without abuse is to measure cell temperature and taper the charge accordingly. The circuit uses a thermocouple for this function. A second thermocouple nulls out the effects of ambient temperature. The temperature difference between the two thermocouples... A commercial diode is the detector in this highly accurate radiation monitor. The lowdrift FET-input op amp amplifies detector current to a usable level, and the chopper-stabilized amplifier then provides additional gain while minimizing any error caused by ambient-temperature fluctuations The detector is made of fine wires spaced about one or two inches apart.

Can I replace other diode instead of BAT85 diode? Maybe I could use a 1N60 diode?
Thanks for attention!

what is the higher frecuency i can get with this receiver? i want to listen 80m band.

Probably the 1N4007 is a fit, but you can get BAT85 too.. I could order for cents, so not a terrible cost. the optimal frequency range is the same as an old radio's AM band. I use this cirle as a receiver in a metal detector. made a transmitter with a 555 timer approxymate 60 KHz, and tuned the AM receiver.

I used an lf356n and the pin 2 and 3 were reversed (check the datasheet youll see what I mean)
