Hi All,
I am new bee in RF electronics.
I have used MK484 for AM reception using loop stick antenna. I am interested in AM reception through Whip Antenna (followed by JFET buffer/Amplifier).
Interestingly Whip Antenna can be used for VLF LF and MW reception as mentioned in many websites around but unfortunately for me none worked and i just hear tick tick loud sound with Whip antenna. One of the circuits i tried is posted in web site Low Freq. Antennas Figure 7. It is claimed by author that it covers 1ookhz to 15 Mhz so AM should be there. Can any one tell me why i am getting this sound. is it Extra gain ( i don't think so) or any other issue. i am using bread board for circuit designing. Preamplifier i have used is attached.
If any one has used whip antenna in AM receiver front end then please provide details.
Thanks
