I have been asked by Don Cox, Director of OEM RACES to give this presentation on how, we as a Team, can best communicate electronically using available web-based tools. I will give you an overview of the tools and then we will discuss each one.

2

We will discuss the following, not necessarily in any particular order.

•Who can upload and download files•Membership lists•Ease of use•Cost

3

• Google• GroupSpaces• OEM CMS• Wiggio• Yahoo

4

Google

• Limited to one email list at at time – per login email address – this applies to all email lists with the exception of Wiggio and Groupspaces, which will be discussed later.• Not as many features as the other

brands• Members upload and download

files

5

Groupspaces• Can handle as many email lists as

needed according to the plan you choose.

• Plans range from Free, to paid • Members can upload and

download files• Track when a person opens email

and if they don’t• Email addresses can be added

via .csv spreadsheet.

6

OEM RACES CMS

• No capability of managing email list

• Only “Authorized personnel” can upload files

• Anyone can download files7

Wiggio• As many lists as desired• Free• Members can upload and

download files• Members can go to website and

read past emails• Email addresses can be added

via .csv spreadsheet.8

Wiggio• Host virtual meetings• Easily add members• Add Subgroups to the Main

Group

9

• Yahoo • Limited to one email list• Any member can upload and

download files• Membership – • By invitation• Ask for membership• No limit to membership10

Electric Principles

VOLTS: electrical tern or electromotive force (EMF) Basic unit of electromotive is measured with a Voltmeter About 12 volts for mobile Radio

Current: Measurement of flow Current is measured in AMPS Measured with AN AMMETER

CURRENT

DIRECT CURRENT: Battery what your car has Normal car 13.8 VDC

Alternating Current: What is in your house

Resistance

Unit of measurement is OHM measured with an ohmmeter

CONDUCTANCE AND RESISTANCE

COPPER is a good electrical conductor

GLASS IS A GOOD INSULATOR

POWER

Power is measured in WATTS This is what the meter on your house is measuring

Power Ratios (DB)

3dB is approximate a change of double (2 to 1)

-6 dB approximate decrease change from 12 to 3 (4to 1)

10 dB approximate (10 to1)

ELECTONIC PRINCIPLES AND COMPONETS

RESISTOR: used to oppose the flow of currentPOTENTIOMER

CAPACITOR Stores energy in electric field The Farad is the unit of measurement

Inductor (coil) stores energy in a magnetic field called inductance and measured in Henery’s

Parts

A SWITCH A component to disconnect or connect FUSE component to protect circuit components

Batteries CARBON-ZINE are non rechargeable and produce about 1.5 volts

NiCad batteries are declarable and produce about 1.2 V

Parts are PartsDiode allows current to flow in only one direction ANDOD and CATHODE are the electrical parts and the cathode is usually identified with a Stripe

TRANSISTORS used to control current flow GAIN term to describe transistors ability to amplify

FET FIELD EFFECT TRANSISTOR is a transistor with a gat electrode

LED) LIGHT EMITTING DIOD

A RECTIE changes AC to into varying direct current
