A Bitx20 band pass filter from Pa1ed:
the bandwith of my bandpass filter in the Bitx 20 was very small.Only 100KHz or so.I found this filter on the internet,and after I,ve build the filter I found out that this was the filter used in the Bitx20A from Hendricks QRP kits.Because I wanted to use the whole 20M band (14.000MHz-14.350MHz) I,decided to build the Original bandfilter which was designed in the Bitx20 V1 by Ashar Farhan.
