[KYHAM] Radio Theory and Construction Workshop

[wl fuqua]

         We will hold our Radio Theory and Construction workshop this 
Saturday, September 21, 2002 in the basement of the Red Cross Building at 
1450 Newtown Pike, Lexington, KY. The Workshop will begin at 10:00AM and 
continue until noon. Sometimes we stay longer.
This work shop is for anyone interested in the subject of radio theory or 
construction. Anyone may join in 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 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). This kit cost about $20 
and it is perfect for learning soldering, component identification and 
basic radio theory. Sources for these kits are:

Edlie Electronics    http://www.edlieelectronics.com/

Electronics express   http://www.elexp.com/.

There  are two styles of kits. One has an integrated circuit audio 
amplifier (AM-550K) and the other has a transistor audio amplifier 
(AM-550KT). We prefer the one with the integrated circuit Amplifier but you 
can use the other if you like or if the preferred one is not available. 
Also, a very basic portable cassette tape player will be needed. These are 
less than $10 at many department stores or can be found in garage sales for 
a $1 or so. It has been reported that WalMart has them for about $5. The 
cassette player will be modified to become a sensitive audio amplifier for 
future experiments and trouble shooting. I try to encourage participants to 
be resourceful and use common items found around the home. The tape player 
is a good example.
There are also other recycling projects that we may do, such as making High 
Voltage power supplies for tube QRP projects from old PC power supplies. 
You can make a inverter power supply that will run off 12 volts and produce 
120 or 250 volts DC along with 24 volt filament voltage for tube radio 
projects. These are perfect for some old military tube radios.
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.

Please let me know if you are coming and what you have to bring or would 
like to discuss at the workshop so I can have some time to prepare and 
gather any materials that will be helpful. Even if you are not coming to 
the workshop I would appreciate an email. I like to stay informed on your 
project's progress and I am always happy to answer any questions you may 
have. If anyone is interested in starting the beginning basic workshop or 
if you know of someone please contact me.

         There is a hamfest on Sunday Sept. 22 in Cincinnati, Ohio. Here is
