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

2020-05-19 Transistor Tester And Other Components

Here is a writeup from another radio enthusiast about his newly purchased Mega 328 uC based component tester. They come in handy for testing electrolytic capacitors especially for ESR – equivalent series resistance. The tester will also test silicon and germanium transistors, handy for making a judgment on how leaky it is. I have a

from FB comment in Vintage Transistor Radios Pablo E. Laredo I used to buy LEDs from small vendors on eBay. I found that most of the 5mm LEDs that I got from the small vendors were seconds, the chip wasn’t centered so the beam was off center, or there were bubbles in the clear epoxy

2020-05-16 Renewables Vs. Nuclear Power Plants

The actual costs of the new NPPs (Vogtle in the US and Okiluoto in Finland) have gone far overbudget – tens of Billions of dollars, plus years of delays. It’s not antinukers, it’s huge cost overruns and delays that are preventing investors from building new NPPs. NPPs are not capable of competing against renewables. The
