hi . thnx for ckt . u call ur ckt eavesdropper detector but the ckt detect any radio freq in range 1-1000 mhz.?????

thanks . the one which is modulated with sound .

actually i want  a circuit that can detect IR frequencies .

so can we connect a photodiode with the circuit , to detect IR signals ? if yes then how ?

hi
i like the circuit . can u suggest amodification so that it can detect IR frequencies. :)
