From FB group Building Transistor Radios Nick Bastian (High L, low C circuit is better) depends on a lot of factors. From what I’ve read, hams try to keep the L low and the C high to give lower wire resistance and higher Q. In this case, the radio has to be very small so

For FB group Building Transistor Radios I rigged up two of the transformers, connecting six 600 ohm windings in series and two 600 ohm windings in parallel. I measured the voltages to find the turns ratio. I applied 6 volts to the 6 series windings, and measured 1 volt on the two paralleled windings. This

From FB group Orange Talk I’d like to tell you a true story. Back before Direct deposit, we (SAC) had to set up check handout tables for the students on Financial Aid. We had four lines, A thru G, H thruvM, etc. Each had an accordion folder with the checks sorted alphabetically. One day I

From FB group Vintage Transistor Radios James Ault Thanks for reminding me. I gave my 22 yr old car to my sister and after awhile the door started rattling. I found that the post that sticks out for the door’s latch to latch onto used to have a nylon sleeve, but age had caused it

from FB group Orange Talk Mary Mickey Clancy-Kreutz I read some of the 2016 Republican platform, and I was disappointed by how much of it was attacking the “present administration” (Obama), and Democrats. Yet they talk about valuing human rights, then criticize amnesty programs. Many other things were disappointing. They use the term ‘environmental extremism’

From FB group Bell Telephone of… We had a hotline phone from So Cal Edison that was supposed to receive calls only. They would call us on a hot day when the power demand exceeded the supply, and they were going to shut down the a/c on buildings. We got a discount on the electric

From FB group Bell Telephone of… That brings up a thorny question. We moved into a brand new bldg, and when it got hot over the weekend, Monday morning I had to go out to the other campus and find out what happened to a few phones. The phones in 2 of the second floor
