MFJ CW Gear
Overview
This unit covers two MFJ Enterprises pocket-class CW instruments. The **MFJ-419 CW Elmer** is a dedicated Morse-code practice generator — a receive-side learning appliance (random code groups, Farnsworth-method training, and a USB text mode that plays back typed or pasted prose as code) with no radio in the loop. The **MFJ-422D Electronic Keyer Paddle** is the complementary send-side tool: an iambic electronic keyer with an integrated dual paddle that plugs into any HF rig's key jack to put the operator's CW on the air. Together they form the CW practice-and-sending side of the radio shack, paired with the Xiegu X6100 for on-air work. Migrated from the Scanners project as part of the Scanners/Radios restructure Stage 2 Phase 2 (2026-06-16).
Context
These are bench-only CW tools — neither transmits or receives on its own. The MFJ-419 is the off-line practice room (learn to copy and send code without taking up bandspace or going on-air), while the MFJ-422D drives a real rig — the Xiegu X6100 — for actual on-air CW sending. MFJ Enterprises wound down in mid-2024, so both are secondary-market only with no remaining factory warranty or parts service.
