Step nine : do the rest...
You will need the following: Ok, so now you have the hang of things. There is nothing new you need to know to finish this circuit. the only tricky bit is to make sure that the 2SC2538 or 2053 Transistor and the 2SC1970 Transistor are soldered the right way round. With the 2SC2538 the flat side will face 'down'. With the 2SC1970 you will see it has a silver side. This should face 'up'. So do the rest:
51K === (green-brown-black) (resistor)
10PF Ceramic (capacitor)
1K === (brown-black-red) (resisitor)
3.5-4.5 Turns Molded Coil (5mm diameter bobbin)(inductance=ca.0.3MH)
0.01MF (103) Ceramic (capacitor)
0.01MF (103) Ceramic (capacitor)
10PF Ceramic (capacitor)
300K === (orange-black-brown) (resistor) Solder 2SC1970 (see above)
1MH Fixed RFC
10PF Ceramic (capacitor)
33PF Ceramic (capacitor)
3.5-4.5 Turns Molded Coil (5mm diameter bobbin)(inductance=ca.0.3MH)
33PF Ceramic (capacitor) And THATS IT!!!!!!!!!!!!!!!!!!!!!!!!
Next, when we get a few minutes, we will tell you how to connect teh antenna and the power. You can try this yourself already...You'll be able to get it going by looking at Tetsuos diagrams, just remember the power in is DC not AC...try it but watch this spot as their will be this documentation online soon....heres some photos of us for interest...
