That looks fabulous Rob. I'm glad the coil was helpful - was it tricky to reconnect the fine wires from the internal bobbin?
Even without an RF stage, these radios impress me. In fact, one of my favourite modern communications receiver brands chose to go straight in to the mixer stage (via bandpass selection) and still achieved microvolt sensitivity. If you can hear the atmospheric noise jump when the antenna is connected, generally you have enough sensitivity.

I don't hold with furniture that talks.
