The simplest possible QRP transceiver?

What do you think is the simplest possible QRP transceiver? The Pixie or Micro80? Have you built a functional transceiver with even fewer parts than these famous QRP radios? If so, post a link. I believe it should be possible to make a transceiver with fewer than 20 parts in total.,

Hi Roger
Keep it coming. You never know who'll find you via Google.

Anyway, an idea for keeping the parts count down in a QRP DSB rig (and probably help in CW) is the TDA2822. It's a tiny (8pin) dual audio power amp - like 2xLM386 needing from memory only the output capacitor, and if you need lots of output you can bridge the amps (sort of like push-pull) to give quite respectable volume from 2xAA batteries.
