Looks like we had somewhat similar ideas. In my version I used a 3 stage Pi filter in the output and 100uH/0.01 as the low pass to the audio amp. What is your receiver sensitivity like. Mine was low and I am starting to suspect my crystal ear piece of having low sensitivity (it is about 20 years old). I had to add an audio amp with transformer coupling to drive a walkman style headset.

Like your website.

Thanks for publishing this, Alan. I'll try a few of your mods in my version, which is still at the breadboard stage.
