I am looking for anyone with personal hands on experience with optional
Narrow filter for the YAESU FT101ZD.
YAESU add-on filter are the XF8,9HC 500 Hz for cw.
I would like to increase the selectivity on cw to eliminate adjacent
channels during weak signal dx a specially
on low band .
I am looking for any NARROW (250 Hz) crystal filter for my old but good
doing topband FT101ZD.
Anyone know what filter will be possible to put for my radio ?.
Any answer will be appreciated
