TECHNICAL FORUM
Power Supplies
Saturday March 13, 2010
8:00 AM
Tents of Grace Cafe
North Walnut Street, Gnadenhutten, Ohio
(the meeting will be in the Ice Cream, Sweets, and More room)
Join us for breakfast or a cup of coffee & the topic this week
will continue the series on power supplies; the individual
sessions will not necessarily follow each other, but may be
scattered throughout the coming months.
This month we will discuss additional rectifier combinations you may
find or want to use in power supplies, advantages/disadvantages of
the various circuits, filtering, and will view the waveforms to see the
effects of changes to the progressive design.
If you don't know what this is all about, by all means come and
find out just how exciting your amateur radio experiences can be
when you understand more about your power supply
(or when you design your OWN power supply!).

Special Canadian Callsign Prefix |
|
|
|
|
The use of a Special Event Prefix callsign has been approved by Industry Canada and can be used by all Canadian Radio Amateurs. It commemorates Galileo's first use of an optical telescope and the subsequent discoveries he made in his lifetime.
Starting January 1st until February 28th 2009 all Canadian amateur radio operators may use the special prefix.
VE changes to CG
VA changes to CF
VO changes to CH
VY changes to CI
For example:
VE7DAO = CG7DAO
VA3DAO = CF3DAO
It will certainly attract hams from around the world to call and find out what the new callsign is and will promote the International Year of Astronomy.
A Special Prefix QSL Card has been designed and available for download for this unique Canadian event.
