[KYHAM] Radio Theory and Construction Workshop

[Bill Fuqua]

	The Radio Theory and Construction Workshop will meet Saturday, March 6, 
2004 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.

Next Saturday I am hoping to go to the Cave City Hamfest.  If I do I'll 
cancel next Saturday's workshop. So keep an eye out for next week's notice.

This weekend's workshop we will talk about amplification and tuned 
circuits, particularly in regards to the Tuned Radio Frequency   (TRF) 
receiver and  intermediate frequency amplifiers and filters in a 
Superheterodyne receiver.  This discussion will lead into one next time 
about oscillators. How they begin oscillation and continue to oscillate and 
generate a coherent signal. This is a very interesting topic because not 
all oscillators require feedback. This is likely a surprise for many of you.
