SolderSmoke Direct Conversion Receiver Used in an SSB QSO in New Zealand by ZL1AUN

 Aaron ZL1AUN used his homebrew SolderSmoke Direct Conversion receiver in a 40 meter SSB contact with his fellow New Zealand radio amateurs.  His transmitter was a modern commercial rig, but his receiver was the Direct Conversion receiver. 

I think Aaron's video is an excellent demonstration of how stable and useful this receiver really is.  

The next step for many will be the construction alongside the DC receiver of a Double Sideband transmitter.  You could make it with only the receiver PTO serving as the common stage.  Just build another mixer, a mic amp,  and an RF amp with low pass filter.  Switch the DC voltage and the antenna from T to R and you will be on the air, on phone,  fully homebrew.  

Here is an article describing how I did this on 17 meters in the Azores in 2001:

Here is the Doug DeMaw article in CQ magazine that got me started in homebrew DSB:
