[KYHAM] Radio Theory and Construction Workshop

[Bill Fuqua]

The Radio Theory and Construction Workshop will meet Saturday, May 8, 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.

We are currently working on designs for 10 meter and 6 meter CW QRP 
transmitters. The 10 meter one will be on 28.305 MHz just inside the novice 
voice band. And the 6 meter one is at 50.350 MHz.  The frequencies are 
determined by some crystal oscillators that I got in quantity. An 
oscillator, one transistor and a low pass filter will make a real nice 1 
watt CW transmitter.  I am hoping that we can then make these into PIXIE2 
like transceivers. If the transistor will also function as a Mixer or 
Product Detector as well. If not we may go to a separate receiver circuit. 
Which should out perform the PIXIE2 transceiver but will still have few parts.

The Following Saturday May 15th we will not meet due to the Dayton 
Hamvention. I will be there  May 14, 15 and 16. I will be leaving 
Lextington on May 13.  This the largest hamfest in the world. You may want 
to set aside some time to attend it.If you are attending the Hamvention I 
will be at flea market space 2905.
