TRGHS: Hearing K5HCT Through a Single 12AU7 Tube with 12 Volts on the Plate (Video)
The lower portion of the column on the right-hand side of this blog is where I put links to interesting blogs, YouTube channels, and web sites. Yesterday one of the links there led me to the above video. It presents a regen receiver using one 12AU7 tube and a 12 volt power supply. Wow! I have many of those tubes. And at 12 volts I am unlikely to electrocute myself. Count me in.
In the final minute or so of the video, the builder tunes around the 40 meter phone band. Suddenly I heard a familiar voice. It wasn't recorded long enough for the callsign to be heard, but I was pretty sure it was our old friend August, K5HCT (Here Comes Texas) from Odessa.
Odessa, Texas is a good skip distance from both California and Virginia, so Pete and I have both talked to August many times. When I was testing out new homebrew contraptions, August was often there to help me out.
I was pretty sure it was August in the video. I checked with Pete -- he too recognized the voice. Then I got an e-mail response from August -- yea, it was him.
On the air, I often recognize a voice before I hear a callsign. In this case it happened via a somewhat wobbly regen and the internet.
THE RADIO GODS HAVE SPOKEN.
Now where did I leave those 12AU7s?
