Longwave Radio Circuits

[electronicdx]

Hello,

I have something to ask, how is a longwave radio different from a AM radio receiver. Is it the ferrite coil antenna and also the oscillater/mixer coil? I want to learn more about on how to build a
radio receiver that covers 10 kHz to 150 and also 150 kHz to 520 kHz. Its something for me to learn on how they work and also I want to work on something different.

Also why is there not any long wave radio receiver kits out there, I bet many hobbyists want to build a longwave band radio kit of their
own using a soldering and a bunch a tech tools. I certianly do see
AM and SW radio receiver kits, but no longwave related kits except
the Ramsey VLF converter kit. I hope in the future, especially for
NDB DXers and hobbyists that we get LW radio kits, and also look
into LW and MW kits like 2 band radios or 3 band LW-MW-SW kits.

Please help me out and others who are interested in this, and I hope to get further in low frequency electronics for ham radio
and radio science purposes.

Thanks.

The structure of Long wave radio receiver should be more or less the same as that of AM radio. Just the difference in frequency and the corresponding coils.
