Subject: Kit Building Class offered by HCRA

 

The HCRA is planning a kit building class with the attached kit.  If you are
interested, additional information, schedule, recommended tools, etc will be
sent to you.

I would like to place the order for the kits on the Monday after the
Thanksgiving weekend, and schedule the class for January/February depending
on everyone's schedule and interest. So if you are interested, please do not
procrastinate, and send a check to the HCRA P.O. Box (on the attachment) and
send me an email with your frequency of choice.  

Thank you for your participation in the HCRA.

Club Kit Building Project

 




The HCRA is planning on a kit building class and has decided to use the
following kit as a standard.  Included in the class will be component
identification, basic soldering skills, and if necessary some trouble
shooting skills.   3560 khz is being recommended as 80 meters tends to have
slow CW, 3560 khz is a tech frequency, and it is also a QRP calling
frequency where more activity exist.  If you are interested, please send me
an email, and send a check to HCRA   P. O. Box  562    Agawam, MA  01001
The email will alert me to go looking for the check.  Thank you

The Rock-Mite is a crystal-controlled direct-conversion transceiver
available for 80M, 40M, 30M or 20M.   It features an on-board 8-pin PIC
micro-controller which controls a T-R offset on key-down. A brief tap of a
pushbutton control switch reverses the offset to yield a second operating
frequency. Pushing and holding on the pushbutton activates the speed
adjustment routine for the built-in Iambic keyer. If you'd rather use an
external keyer or straight key, there's a 'drop-through' mode which allows
use of an external keying source.

 

You'll note in the image above that the Rock-Mite uses two crystals. The
first is used in the local oscillator for transmitter and receiver. The
second is used as a receiver front-end filter. This crystal significantly
reduces the SWBC energy present at the receiver mixer; as a result, unwanted
SWBC reception is dramatically reduced.

 

The Rock-mite uses one surface-mount part with fairly large spacing. There
are no toroids to wind, so assembly should be a snap! The Rock-Mite uses
subminiature epoxy-encapsulated RF chokes instead of toroids.

What a great idea from Jim, here's a few additional comments.

 

Thanks to the efforts of Jim, K1JAW we are offering a kit building class to
our members. Jim has chosen the Rockmite CW transceiver, a good beginner kit
that can be put to use immediately on the air when completed. If you choose
the recommend frequency you can even have fun with other members as they
complete their kits.

 

In addition to sourcing the kit we will also have a few 'Elmers' available
to help you if/when necessary. Whether it be understanding the instructions,
soldering techniques to testing and making that first contact our Elmers
will be there for you (if you need them). The combination of a good, proven
kit and experienced help on tap will pretty much insure success.

 

Please take a look at the attached flyer (if for some reason the attachment
isn't attached I'll resend with it right in the message), send your check in
to the PO Box and pick up your kit at the next meeting. What could be
easier? Just think of the excitement of actually making a contact with a
transceiver you built yourself - speaking from experience it truly is
exciting.

 

Jim, KK1W
