Anyone want to guess what demographic this vintage radio was marketed to?

Marconi, who some people say is the father of radio...

Others know better...read on...

"While the Supreme Court declared the Marconi patent invalid, it affirmed prior work and patents by not only Tesla, but by Lodge and Stone as well. As for the Lodge and Tesla patents, the Supreme Court’s opinion discussed Tesla’s and Lodge’s work in two pages and three pages respectively, but devoted a full twenty pages to Stone’s work. What was so important about Stone’s radio patent? “Stone’s [patent] application,” the Court wrote, “shows an intimate understanding of the mathematical and physical principles underlying radio communication and electrical circuits in general.”


The Supreme Court also ruled on Ambrose Fleming’s patent, issued in 1905, for a diode vacuum tube capable of “converting alternating electric currents and especially high-frequency alternating electric currents or electric oscillations , into continuous electric currents for the purpose of making them detectable by and measurable with ordinary direct current instruments.” The Supreme Court ruled the Fleming patent invalid because of an improper disclaimer. In November of 1915, the Marconi Corporation issued a disclaimer to the Fleming patent that restricted the invention to use with high frequency alternating electric currents such as are used in wireless telegraphy. The Court maintained that using the diode for rectification of low frequency currents, as stated in the original patent, was known art at the time Fleming filed his patent application and therefore ruled that the original patent was invalid. Moreover, it decided that the disclaimer filed in November 1915 could not prevent the patent’s invalidity unless it occurred “through inadvertence, accident, or mistake, and without any fraudulent or deceptive intention.” The Supreme Court also judged that Fleming had delayed an unreasonable length of time in making his disclaimer. Therefore, because U.S. patent law holds that an invalid disclaimer automatically invalidates the patent to which it refers, Fleming’s patent was invalid."

Let the debates begin!

Yeah, that doesn't surprise me. I bought it from an ad I found in a Popular Electronics Magazine back in early 1967. It was made by Kuhn Electronics in Cincinnati. This is one of the few photos that I could find. You can read my previous post on it from 4 years ago at the link below:

I liked the image, so I "tried" to improve it, but I finally met my match, this image kicked my butt and I was not able to do much with it.

My radio was a dark, like "Forest green". Had a separate collapsing/extendable vertical antenna (36" +/-) and a loading coil at the bottom, which was covered with a UV resistant sleeve, in case you wanted to mount the antenna out on your window sill or some place. The antenna connected to the back of the radio via a "banana plug".

It was a tube-type radio. The above photo shows the radio in [what looks like] a metal cabinet. Mine was made of 1/2" plywood. Truly, it was!
That little 4 ohm speaker could fill my 8' X 8' bedroom with a big sound.

Omega-Ti...don't sell yourself short. You did a great job and I really like the blue color!!

P.S. Found this just now. You can almost see the wood grain from the plywood on this model...

Yeah, I found that earlier, but it was so small that I could not enlarge it very much due to the lettering degradation.

That is a rare scanner I'm going to say 1977, it was only VHF high band Crystal control but it also had a slide rule tunable dial. There was a pro 6 that had more band coverage, I still own my Pro one which was a VHF high slide rule dial similar looking radio, actually had two crystals also but they didn't scan they were just selectable. These were all GRE radios.. g r e Japan.

Here is a weird hybrid scanner for those who were either too cheap to buy a crystal, or those wanting to see if a frequency was worth listening to before buying a crystal.
You know, I thought I had seen them all but honestly never saw that one. I just looked up and said 1973.
I think because it was high vhf only and back then I needed low band for many local FDs.
