can any one provide me the inductance value of the coils used in bitx20 v3


 

BITX20hi,
I am trying to construct my bitx20 v3,and I cannot find the insulated copper wire of the same gauge in my local market,
can any one provide me the inductance value of the coils used in bitx20 v3,
T1,T1A,T2,T3, the circuit says 13 turns of 32 swg gauge wire on tv balun core..
thanks

The wire gauge for the broadband transformers is not very specific. If
you can get those many turns through the toroid/binocular former, you
are ok. As they are broadband in nature, they will also be broadly
tolerant of wire size etc. As long as it is not so thin that the
current passing through will melt it!

The value of rf band pass and power amp's low pass filters is given in
the original circuit.

I have been able to find insulated copper wire at stores that sell fly fishing gear. And at craft stores that sell the things to make beaded jewelry. Don't know how good it is but they have it in all the colors of the rainbow.
