The 2N3904 rig will never happen and this is a result of the reality of the very, very small interest in building anything these days.
It was a suggested project doomed to failure as using a 2N3904 throughout the rig, results in building in the old way of doing things that we have now replaced with modern technology.
Who in their right mind would settle for a drifty Analog VFO when you can have a Digital VFO and the BFO comes as a bonus.
The real negative... no circuit board and no kit. I know it can be done so I have no magic goal to personally be achieved.
A singular benefit is teaching the very few, the tired and the brave, a process for building a true homebrewed SSB radio using a common device in every active circuit.
Ten years ago, I along with AI6YR created a close cousin (with the same teaching goal) and it was published in QRP Quarterly under the title LBS standing for Let's Build Something. A few units were built by the ham community, but it never went viral.
So, Blog Readers you dodged an ad nauseum treatise on the Emitter is biased at this point. Lucky you.
If you know, then you really do know when it is time to go. Likely my time is better spent in making unboxing videos on radios and products from "Chine" as history has shown that is what the customer wants. Bottom line simply stated keep out the technical content and emphasize the flash and cash.
