Description: This listing is for a MFJ 422B-X Electronic KeyerThis keyer seems to work fine. I put a 9V battery on it and it powers up fine. It has a stereo 1/4 Key Jack added to it. It works in both semi and automatic modes including iambic. I noted the tone of the keyer is lower in pitch and this may be adjustable internally but I’m not positive. It sounds around 500Hz so not terribly low. Selling as it with no returns. It is possible you might need to tinker with it, this was pulled from a box of parts in an estate and I know zero history on it. I have other MFJ keyers listed this week. Fits on the Bencher BY-1 style CW keys of the era. You will receive the EXACT item shown in the picture.Thanks for looking!!! _gsrx_vers_1653 (GS 9.7.5 (1653))
