This was our 1 Year Anniversary of the YL Net
Week 52 Wow !! Awesome
We had 12 CheckIns with 4 YLs on Echolink and 4 OMs listening on EchoLink and no telling how many YLs and OMs were listening on the 444.100 Repeater
Announcements included:
- Our next fellowship will be Sept 22 at 1PM EST -- with food and fellowship and a HARP concert by K0MAI
- The Tri State Ham Club is presenting a DSTAR 101 course
- Listen to the ARRL News on 442.650 repeater at 7:30 EST every Monday
- Listen to the World Wide news on the 442.650 at 7:30 EST every Weds.
Technical Questions mostly related to further information about Soldering 'how to's'
Technical Training by AC4HH dealt with more details related to our Soldering event. Specifically she provided information about Resistors, Capacitors, and more. She sent us a copy of the information she presented and it is included here : __________________________________________________________________
YL Lesson: Resistors, Capacitors, and Semi-Conductors
"Tonight we’re going to go over the exercise about identifying resistors in your booklet that came with the soldering kit. But first, I thought I’d define some of the components in the kit.
First is the RESISTOR. The resistor as defined in the soldering practice kit is a “component used to control the flow of electricity in a circuit. It is made of carbon.” Definition from the Internet is: The resistor is a component that resists the flow of current. It is a passive device that doesn’t do anything actively in the circuit, but resistors allow you to have the current and voltages you want in your circuit. It goes back to Ohm’s Law beginning with the formula: I=E/R. Where (I) is the current – sometimes given as (P) for power – equals voltage (E) or (V), divided by resistance (R). The current is the amount of charge flowing through a certain point, and the resistor slows down the flow of the current or charge.
Now let’s talk about CAPACITORS. Our soldering kit booklet defines a capacitor as an electrical component that can store electrical pressure (called voltage) for release when needed. The Internet states that capacitors are energy-storing devices similar to a battery except the capacitor releases its energy much more rapidly. For example, a capacitor if fully charged, can release its energy all at once, such as in a flash bulb. You can charge a capacitor simply by wiring it up in an electrical circuit. When you turn on the power, an electrical charge gradually builds up on the plates – it contains a positive plate and a negative plate. Capacitors are often used as timing devices.
The last component for today is a SEMI-CONDUCTOR. Semi-conductors are like voltage regulators. They are made of a material (often silicon) that has an electrical conductivity falling between that of a conductor –metals, such as copper or gold and an insulator such as glass. Probably you have seen power poles with glass insulators near the top. The semi-conductor conducts current, but only partially.
Quick review: A Resistor resists the flow of current, allowing you to set the current and voltage you want in your circuit.
A Capacitor stores electrical current and can release it much more rapidly. It contains a positive and a negative metal plate.
A Semi-conductor acts as a voltage regulator. It conducts current, but only partially. ... ... ... "

The EMERGENCY PREPAREDNESS TOPIC was presented by KE4RP and was important information about Landslides. At the conclusion of the presentation and discussion she recommened we go to the Ready.Gov website for more information and details.
And thus concluded another wonderful YL Net.
Join us and listen or participate every week
on the 444.100 repeater or via EchoLink Node 68581
