Asbestos is not as bad for you as Democrats...


According to Ron, who is restoring a 1930's rare Zenith in this video.

Ron is a glassblowing master who custom makes repos of rare and exotic tubes, along with being a master restorer.

The dem bashing puzzles me, as Ron is transgender.

The good cabinet...




Playing the good chassis...





This thing is LOUD AND POWERFUL and filled the garage with sound, could be heard clearly outside. The video sound doesn't do it justice.

On the back, near the end of the video, you can see "FM The Armstrong Method" sticker. Major Edwin Armstrong was the inventor of the Superheterodyne circuit, and F.M. radio as we know it.

He commited suicide after being hounded into ruin by Davis Sarnoff, C.E.O. of R.C.A.. Sarnoff was heavily invested in A.M. radio, and saw F.M as a threat. So, Armstrong paid the price for being too far ahead of his time.

Also on the back are stickers from long vanished radio repair shops, with phone numbers that begin with letters.

Pure living Americana.

Got my Tecsun PL880!

Ordered the deluxe kit version, with cool carrying case and extras.

So far this radio is amazing me.

The case is emblazoned with a big "TECSUN" logo!

And you get a giant poster of the radio with specs on it!

Army Tank Radio & Chicken Wire - Eavesdropping on Apollo 11 on the Moon!

Apollo 11
Chris Graney

The nearly forgotten story of how a radio amateur successfully detected transmissions from the first men to land on the Moon.

In July of 1969 a ham radio operator and amateur radio-astronomer by the name of Larry Baysinger, W4EJA, accomplished an amazing feat. He independently detected radio transmissions from the Apollo 11 astronauts on the lunar surface. Fortunately, his accomplishments were recorded by Glenn Rutherford, a young reporter for the Louisville (Kentucky) Courier-Journal. “Lunar Eavesdropping: Louisvillians hear moon walk talk on homemade equipment,” sporting Rutherford’s byline, appeared in the Wednesday, July 23, 1969 issue of that paper — front page of section B, the local news section (see Figure 1).

Rutherford opened the Courier story with “Thanks to some homemade electronic equipment, including a rebuilt 20 year old radio receiver from an Army tank (see Figure 2) and an antenna made of spare pieces of aluminum, nylon cord and chicken wire (see Figure 3 and 4), a small band of Louisvillians was able to ‘eavesdrop’ Sunday (July 20) night on the American astronauts’ conversation directly from the moon.”

The story discussed how Baysinger recorded 35 minutes of conversation from VHF signals transmitted between astronauts Armstrong, Aldrin and Collins (he did not attempt to pick up the encoded S-band signals from the main Moon-Earth communication link).1 These 35 minutes included the time during which President Richard Nixon transmitted a message of congratulations to the astronauts.

Rutherford’s story briefly mentioned how Baysinger had been previously successful in constructing a device to detect radio signals from Jupiter and in tracking and reproducing pictures transmitted from Earth-orbiting satellites. It briefly described the antenna used for the lunar eavesdropping project — a fully steerable 8 × 12 foot “corner horn” — and it briefly discussed the amazing sensitivity of the receiver, which Baysinger specially modified for the lunar eavesdropping project. Rutherford finished the story with “Needless to say, the receiver worked to perfection Sunday night.”

Turning Tricks

Blues legend Memphis Minnie worked as a prostitute on Beale Street during the depression, before reaching fame.

She drops the MFer bomb in this song in the 30's, long before rappers discovered it.
