Default Re: More Chinese AM radio kits

Hi

Yes, the worry is whether the components are out of spec. In the 1A2 radio thread, I found the 33uH RF chokes to be very low in value typically 20uH so wouldn't be surprised if other components are sub standard.

I would certainly build yourself or buy a decent capacitance meter if experimenting with radio circuits. My capacitance meters and ESR meters have paid for themselves time over. An inductance meter is equally useful when building radio circuits.
