Re: Crystal CW filter with Version 4 uBITX boards? #ubitx

ajparent1/KB1GMX <kb1gmx@...>

The bits referred to used no transformers at the ens of the filters.

ubitx does.  The transformers convert impedances so what is the impedance of
the 12 mhz filter at 4.1mhz translated by a 4:1 transformer?  What can we assume?
