still not working.

my radio still fails. after much testing and testing. the amplifier finally works. then now the tuning circuit fails. first BJT of the cascode got saturated due to low collector voltage and high base voltage. this means my 200H inductor is BURNING from the 0.2A current that is flowing in my tuning circuit. now i have to supply a 6V to my tuning circuit instead of 9V, and 4V to base voltage of first BJT. crap. there's alot of work to do. i just de-solder 1/4 of my circuit and cramp the new parts in, without soldering them yet. i hope it will work after this modification.

i should just learnt from the seniors - to copy the designs from their seniors, to get a working FM radio and and A, instead of designing it myself, getting a B+ for design and nothing for workability. shall try it once more tomorrow, if not i'll just give up. bah.
