So around the time we were building 40 meter direct conversion receivers, someone else was doing something similar. His product (above) is a lot nicer than ours. He has an S-meter and a digital frequency readout. But like ours, his is built on a wooden board. FB OM.
If you want to see what a direct conversion receiver can do, watch his video (above).
I was really amazed to see him use a modified VFO from a Kenwood TS-820. Not long ago Pete N6QW spotted one of these on e-bay and recommended that I buy it. As with the Yaesu FT-101 VFOs, we bought it for the gears and reduction drives but ended up with the entire VFO circuit. I now have one on my shelf, ready to go. TRGHS.
We are not sure who Chappy Happy is, but "Tezukuri" means "hand-made" in Japanese. The writing in the video descriptions are in Japanese, then Chinese.
Here is the YouTube channel. Amazing stuff here: https://www.youtube.com/@chappyhappy3675 He is clearly a ham. He even works on an old S-38. Who is this guy?

A real great homebrewer but he seems like another one of them who prefers to be anonymous. Evidently he is in the Washington State area judging by the 40M SSB he is receiving, although in his Paraset Transmitter video of August 28, 2017 just after the one minute mark he sends a callsign that sounds like JA7TWC (invalid) although the 7 and the T seem to run together somewhat...
ReplyDeleteHe definitely has the knack!

Nice video. Great combination of wood base/ metal front plate. Lots of rigs in the 30's built that way.
ReplyDeleteBest part was cat sleeping on the mouse. Mine is constantly "supervising" me in the shack from a high vantage point.
