BITX20 component list


ik1zyw
 

Hi!
Has anyone attempted to list all BITX20 components? I haven't found
any link on Ashan's page. Here is my attempt at listing all
components, except for the IRF510 PA (had no time).

Please warn me off the list if corrections are needed.

It's me again.

I have uploaded in the Files section a TXT file with a component list
for BITX20. It DOES include driver/PA section but it DOES NOT include
inductors. The list is meant to be a list you give to the shop
attendant and then return home with everything you need to build a BITX20.

Tap washers can be purchased at a hardware store, which usually
doesn't sell electronic components. Coils wire can be salvaged from
old transformers.

Please someone cross-check my work!
