A great QRP accessory! The AF-1 active CW filter really brings those
distant signals right up out of the noise. The kit is easy to assemble.
It consists of a simple filter circuit on a small daughter board. the
circuit is inserted into the audio path before the audio amplifier. The
AF-1 works with most popular transceiver kits.
