Re: Two Transistor Radio

Here's one schematic. Not sure if the Nakashuma models were like this. The first transistor is also the detector, and perhaps a preamp, connected to a variable resistor/potentiometer that controlled the volume. https://www.electroschematics.com/2-transistor-radio-receiver/ https://www.electroschemat...

Re: Two Transistor Radio

Google "Nakashuma". It was actually a real brand. I thought Allan Sherman made it up. They have pictures of the Mark 2 and Mark 3, and one picture has the leatherette case with holes in it. No Mark 4 though, the one he said he got. Most of the Nakashuma pictures show radios that look like they're tu...

Re: Two Transistor Radio

I suspect that the two transistor radios were TRF, not superheterodyne. So they didn't need an oscillator, mixer, IF stages with amplification and transformers, just a tuned circuit and a diode. Just maybe an RF Amplifier transistor to bring up the signal level of the ferrite loopstick (some had tel...

Re: WCMU Transmitter Building Fire

At 1349 feet, the WCML tower is now the tallest in Michigan. The WEYI tower was once 1359 feet, but the antenna had more bays to get at one point 4,080,000 watts ERP analog, which was reduced to 2,040,000 watts before going digital only with much less ERP, and only needed a shorter antenna aperture,...

Re: Woman Found Living In Grocery Store Sign

I had some friends who lived in a vacant commercial property near the Physics Building. It was just walled off from the rest of the property with temporary movable barriers. I don't remember where they went for a bathroom or shower. It just had the commercial grade florescent lighting from when the ...

Re: Woman Found Living In Grocery Store Sign

Bigger and better than a lot of apartments in New York City, and a whole lot cheaper.

Probably a lot of students at UM and MSU aren't living much better.

Re: RFK, Jr trying to show he belongs on the debate stage

The truth should come out about all the Kennedy murders and suspicious deaths, as well as other people. Many alphabet departments need to be reformed. There is some hope. A Physicist/Physician just came out with a book after many years of research that refutes the SBT soundly. This is diametrically ...

These are for sale on Amazon. Buy one and take it to wake up in your hotel. They're really loud according to the description. Sha la la.

Re: Your Clock May Not Be Accurate

I mentioned three other methods besides time signals. Most people use their cell phones for alarm clocks in hotels. They can also use a wake up call. You could also bring a small alarm clock and or portable radio with an alarm feature. A small one can easily be packed.

Mill Valley

Anyone remember this? It was played on more modern (not the Sinatra, etc. dominated ones) Adult Contemporary Stations in Michigan back in 1970, even though not on any remaining local charts from Michigan on ARSA. Teacher singer Miss Abrams and her third grade class from California. Drove the acid me...

No concrete reason was ever given to my knowledge.

Tony has a well maintained FB page but never discussed it there, either. I suspect he is bound by an NDA.
Perhaps something just like Laurie DeYoung said about him circa 1980?
