Hilitand MX-K2 Morse Code Keyer Auto Memory Key Controller
Take your CW (Continuous Wave) radio operating to the next level with the Hilitand MX-K2 Morse Code Keyer. Engineered from durable aluminium alloy and powered by a smart PIC-based controller, this compact keyer lets you store, replay, and transmit Morse code messages with minimal effort — perfect for amateur radio operators, ham radio enthusiasts, and CW contest participants alike.
Key Features
- Large Segmented Memory Storage: F1 key stores up to 60 words with power-off data protection; F2 key stores up to 50 words for quick-access messages.
- Data Protection: The power-off protection function on F1 keeps your stored messages safe even when the battery runs out, so you never lose your carefully crafted sequences.
- Command Mode: Simultaneously press F1 and F2 to enter command mode for advanced control — including repeat play (up to 255 times), voice memory toggle, transfer commands, and more.
- Repeat Play Mode: Use the "C" or "E" command to automatically replay stored messages — ideal for beacon transmissions and contest exchanges.
- Simple Two-Button Operation: Just two function buttons and one switch keep operation straightforward, reducing operator fatigue during long sessions.
- Adjustable Speed Control: The R3 potentiometer lets you fine-tune CW sending speed to match your operating preference — rotate down for faster output.
- Buzzer Mute: J1 jumper provides optional buzzer mute for silent operation.
- Versatile Power Input: Compatible with 110–240V supply; runs on 2 × AAA batteries (not included) for portable field use.
- Aluminium Alloy Body: Sturdy, lightweight construction built to withstand regular shack and field use.
How It Works
- Install 2 × AAA batteries (not included).
- Set L/R switch for di/da or da/di paddle orientation.
- Press and hold F1 or F2 for more than half a second — you'll hear "M" to confirm recording mode is active.
- Key in your message. When done, press F1 or F2 again; you'll hear "S" confirming the message is saved.
- To play back a specific segment, press the memory key the corresponding number of times (e.g., 2 presses for the second segment).
- Enter command mode (F1 + F2 simultaneously) to access advanced functions such as repeat play, transfer, and voice memory settings.

Frequently Asked Questions
Q: Does the Hilitand MX-K2 Morse Code Keyer work with all CW transceivers?
A: The MX-K2 is designed as a universal CW keyer controller compatible with most standard amateur radio transceivers and radio amplifiers that support CW operation. Always check your transceiver's keyer input specifications before connecting.
Q: Do the stored messages survive a battery change or power loss?
A: Messages stored in the F1 memory key are protected by the power-off protection function, meaning they remain saved even after the battery is removed or drained. F2 messages, however, are not power-off protected and will be lost when power is disconnected.
Q: How do I adjust the CW sending speed on the MXK2 keyer?
A: Speed is controlled via the R3 potentiometer on the unit. Rotating R3 to a lower value increases the sending speed, while a higher value slows it down, giving you precise control to match your operating comfort level.
Q: Can I use this Morse code keyer for beacon or contest transmissions?
A: Yes! The repeat play mode (activated via "C" or "E" commands in command mode) allows the keyer to automatically replay stored messages — up to 255 times under the "E" command — making it well-suited for beacon duty or contest exchange automation.
