[KYHAM] Radio Theory and Construction workshop

[Bill Fuqua]

My father is expected to go home from the hospital this week. He is doing 
fine and things will be back to normal.

We will hold our Radio Theory and Construction workshop this Saturday, 
January 7 , 2003 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 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). 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.

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.

I have a number of 14.008 Mhz crystals for those who may want to build a 
transmitter for the 20 meter band. These crystals may be disassembled so 
that you can lower the frequency by putting graphite pencil marks on them 
thus increasing their mass.
I can show you how to do this if you are interested. They also are useful 
for making receive input filters for serious contest operators.
Some of you QRP guys may be interested in these as well. There is a very 
simple amplifier design that will take you PIXIE or rockmite to 5 or more 
watts that we may discuss if you want.
