Hello Radio Qrp,

Yes seen those schematics.Great site of yours!
I made poppet part15 transmitter.It uses solid state modulation but distortion figures were high.So a voltage follower was added which could suppy more current without loading the lm386 chip.Now one could have 2 watts output on peaks.

Last year I got frustuated trying various modulation transformers hehe that's why I now prefer solidstate modulator.

Very best regards from joy
