The "CW Interface" adds CW mode to the DB4020 transceiver kit. It is a complete circuit incorporates an automatic keyer with memories, side-tone monitor, TX / RX delay adjustment, independent signal power settings for 40 and 20m, switching for SSB / CW and the necessary control lines for the transceiver processor. A small board is included with the jack for the paddles key, the push button "CMD" and the “SSB/CW” switch.
The pack also includes an I.F. filter plug-in for CW. This filter has a narrow bandwidth about 500-600Hz which greatly improves the CW signals reception.
