300Hz CW Roofing Filter
Roofing filter - 300 Hz wide @ IF frequency 9.005 MHz
For use in the Yaesu FT-DX10 transceiver.
The FT-DX10 is already equipped with three roofing filters of 12, 3 and 0.5 kHz width.
The optional 300 Hz CW Filter provides even better selectivity in situations of very high band usage, e.g. in a contest or a pileup.
The installation is relatively easy and can done by the user.
