2021-05-29 Tucker Carlson Lies About VAERS, Vaccinations and CoVID19 — BTC

In this short YouTube video Brian Tyler Cohen shows that Carlson lies about VAERS, vaccinations and CoVID19. The pundit and sham artist should be made to tell the truth. https://youtu.be/m8D1HhxE0d8 Carlson said 3,300 people died from vaccinations according to VAERS. That’s false! The VAERS says that the death after vaccination does not prove that the

2021-04-28 Colpitts Oscillator For FM BCB

This is a low power oscillator using an air core coil and silver mica capacitors for stability. Parts values are subject to the frequency needed. There is no modulation. For FM the 10 pF capacitor would be lower and include a reverse biased diode as a varicap in parallel. The audio should be across this

2020-10-15 AM & Digital Radio Mondiale

Well, this article wants the Flunked Clown College to let DRM be one of the choices. It doesn’t matter to me because I don’t plan on spending anything on getting a device that will decode HD radio, FM or AM. Even if the next car I buy has it, I will still not be using

Interview (by Zoom) of William Shatner https://inews.co.uk/culture/television/william-shatner-interview-star-trek-captain-kirk-441311/amp The UnXplained is on Sky History Tuesday 2020 June 9 at 9 PM. Quote from article <<Shatner thinks that part of the appeal of Star Trek is that it shows humans as alive and kicking in 300 years’ time. He is not entirely convinced, though and becomes most

2020-05-28 Solid State Shortwave RF Preselector

Comment left 2020 May 29 on YouTube video in the title. This video covers MOSFET, dual gate MOSFET, JFET and BJT tuned preamps (preselectors) for his shortwave crystal radio. “The talk about using 18 volts for the cascode got me thinking about tube designs. When the plates need 100+V, and when the heater to cathode

2020-03-31 Collecting Novelty Transistor Radios

Also FB group Vintage Transistor Radios Collecting novelty transistor radios has a few drawbacks, the most obvious is that they are much rarer than regular transistor radios. Generally the new novelty transistor radios are much more expensive then a regular radio due to their limited production. The customer who just wants a radio is going

2020-03-29 AM Osc + Modulation + Buffer

This is from Electronics Illustrated Projects 1968. It shows crystal sockets, but instead a RF coil may be used and its value will be about 220 microhenrys. And C1 and C2 will have to be changed to bring the frequency down to the AM band. The germanium transistors are no longer available so silicon transistors

2020-03-10 Simple AM Band Antenna Tuning Coil 240 Microhenrys

The standard ferrite antenna loopstick for a 365 pF tuning capacitor has an inductance of about 230 microhenrys. This in combination with the tuning capacitor tunes across the full AM broadcast band. It’s useful to be able to wind your own inductor so it can be used for an antenna coil, a trap to attenuate

2020-02-19 Nobility 15 transistor Radio Repair

2020 Feb 18 – Nobility 15 transistors OTL S/N (?J)29549 I replaced the electrolytic capacitors. The spkr buzzed when I touched the volume control. Nothing from the detector (transistor). It’s unusual. I pulled and tested some IF parts including one of the transistors, no problems found – transistor tested good. I called it a night.
