[KYHAM] Radio Theory and Construction Workshop

[Bill Fuqua]

This Saturday, January 8, 2005 we will discuss and do some experiments 
having to do with how radio signals are created and received. We will  be 
experimenting with the detection of AM radio signals, Frequency Mixing and 
receiving CW and SSB signals using our crystal radio set by constructing a 
Local Oscillator/Beat Frequency Oscillator  on the AM radio kit. If you 
have not been attending the work shop and want to attend to learn more, you 
don't have to have a kit. I will have one set up for these demonstrations. 
And if you want to do it yourself I will be able to supply the materials if 
we have enough in stock and if not by the next weekend.
    We will also make music ( sort of ) with this set up and use a PC 
compatible computer to look at waveforms, analyze frequency spectra and 
make measurements using freeware and shareware programs that can be 
downloaded from the internet.

Now, for the weekly announcement.

*******************************************************************************************************************************************************

The Radio Theory and Construction Workshop will meet Saturday, January 8, 
2005 in the basement of the Red Cross Building at 1450 Newtown Pike, 
Lexington, KY. The basement entrance is on the Left side of the building if 
you are looking at the front Newtown Pike side) of it.The Workshop will 
begin at 1:00PM and continue until 3:00PM.
This workshop is for anyone interested in the subject of radio theory or 
construction. Anyone may join the workshop at any time. This workshop does 
not really have a beginning or an end. It is a continuing effort to help 
those that are interested in knowing more about the internal workings of 
radios (receivers, transmitters and antennas) and/or building them. A ham 
license is not required and there are no age restrictions. I encourage 
young students to participate. Participants will have to obtain their own 
tools and they will need to purchase a beginner's radio kit (AM-550K). I 
have kits in stock so you will not have to wait. Just pay me for the kit 
and I'll order another to replace it. That way we will have some always 
available for new participants.
The Bluegrass Amateur Radio Society's Youth Education Program (Y.E.P.) can 
provide "Now You're Talking" books for students up thru the 12th grade 
participating in our "Introduction to Amateur Radio" and books, kits, tools 
and parts for those in the "Radio Theory and Construction Workshop" at no 
cost. This kit cost about $20 and it is perfect for learning soldering, 
component identification and basic radio theory.
If you wish to join our workshop please e-mail me so that I can add you to 
our list. I have a short questionnaire to get some information about your 
interest, experience and knowledge level. If you cannot be contacted by 
e-mail call me in the evening at (859) 272-9523 and I will add you to a 
phone list. This is necessary because we do not hold the workshop every 
weekend due to other obligations, vacation, hamfest and license exam sessions.
