SOTABEAMS has introduced a low pass filter kit to complement their popular WSPRlite antenna analysis system. The kit provides selectable 7 element filters for 160m, 80m and 40m on a single PCB. SMA connectors are used to make it easy to interface to the WSPRlite.
The kit is rated at 20 Watts and thus may be useful for other applications where a good quality low-pass filter is needed.
