KENT EK-4 vs KENT EK-4M cw keyer
« on: April 04, 2023, 08:13:25 am »
Hello all,
I own the KENT EK4 CW keyer. This keyer can be upgraded to a memory keyer EK4M. It is said that a memory chip eeprom must be inserted. An 8-pin IC socket is available on the printed circuit board. I assume that it needs a serial eeprom.

Does anyone have a similar keyer with the memory expansion? It would also be nice if he took a look at the print to see which 8 pin ic is on it.

I would really appreciate that. leo
