Hi all,

 

I found out that the CW-75 runs much better if I install the internal 9V battery. So my conclusion is that this keyer is sensitive to the supply voltage. Though it says to connect a 13,5 V external line, it seems wise to add some lower voltage, or better regulated?

I thought I’d better share this on the list. Anyone with similar experience?

 

I also found the jumper to get rid of the dreaded dot-memory. What a relief J
