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


 

Doesn't look bad.

For the record, I have not duplicated the in and output transformers for the extra xtal filter. So I only use L1 to L4 and let them transform both frequencies.

Yesterday I had a? mistype, I use 8 xtals and not 10, my wide filter is the normal one from the original schematic.
