I am looking for a Code Practice Oscillator (CPO), such as the MFJ-557 or something like it. I have plenty of keys, so if you have just the sounder, that would suit me well.
I am an Accredited Examiner and I intend to use this when I administer exams for the Morse Code qualification. I also plan to use this at public demonstrations of Amateur Radio. The code is always a crowd-pleaser.
There was an MFJ-557 recently advertised here, but someone got to it first.
