To practise my morse at the radioclub I looked for a simple morse practise oscillator and found Morse practise oscillator kit - Kent and ordered it at the beginning of Februari. It took a while for it to arrive, but it arrived and I built it in one evening. It's a quite simple kit. Which means the power for the whole circuit runs via the morse key, in theory about 120 mA. And that is more than the octocoupler on the CW output of the nanokeyer I built is willing to deliver (50 mA). So I can't use the practise oscillator straight away, there will need to be a small amplifier in between. Some searching suggests I can use a transistor as 'power amplifier'. Time to look at what I may have (which is not a lot) or find a transistor somewhere. Solution: order a bunch of transistors in a collection so I have some in the junkbox. Oh and: The dashes and dots in the title are the word 'MORSE' in morse.
