QRP Hall of Fame
It is a new year and the time has come for the call for nominations for election to the QRP-ARCI 'QRP Hall of Fame'.
You can submit either real mail or internet nominations via e-mail but they must include the following information.
Name & Call of person nominated
Name & Call of person making the nomination.
A full description of why you think your nominee should be in the QRP Hall of Fame (HOF) is needed. Remember the voting body may not know this person and you must convince them that the person is worthy. Things such as "John Doe is a great guy and always helps out at the club" will guarantee he is rejected. Be specific in your recommendation and try to persuade as to why your person should be in the HOF.
The voting body consists of the QRP ARCI Board of Directors, President, Vice-President and last eight members inducted into the Hall of Fame. Nominations may be submitted by anyone, whether a member of the QRP ARCI or not. Similarly, membership in QRP ARCI is not required for someone to receive the honor, since this is an award to recognize those who have made great contributions to the QRP community, not just to the QRP ARCI.
If no nominations are received or the nominee(s) receive(s) less than the required 2/3 vote there will not be an induction at Dayton for 2010. The BOD is adamant that it is not a requirement that we will have an induction. A list of the current members of the HOF can be found here .
Please forward your nominations to BOTH President QRP

AND to the Vice President

Ken Evans, W4DU Kathy Bromley, WQ5T
848 Valbrook Ct. 3424 Brooken Hill Drive
Lilburn, GA 30047 Fort Smith AR 72908-9254
USA USA
The closing date for nominations is March 1, 2010. When a nomination is received, a confirmation e-mail or letter will be sent to the person making the nomination. If you nominate someone and do not receive a confirmation, we did not receive it. You will need to receive a confirmation to insure your nominee will be considered.
Ken Evans, W4DU Kathy Bromley, WQ5T

The FDIM 2010 QRP
Challenge
Need a challenge ?
Can you design and build a ham transceiver with 72 (or fewer) components !
Each year at FDIM attendees have the
opportunity to bring their latest projects and enter them into the "Building
Contest". There are six categories that
are judged by the people attending the Friday night event. Next year we will add a special category called
the FDIM 2010 QRP Challenge.
Normally we do not make FDIM announcements until January, but we thought
that the extra time gained by announcing this in December would help the
participants. So put on your thinking
caps and heat up the irons. Let's see
what can be done with this challenge!
The objective is as follows:
Design and build a
QRP Transceiver using the following rules:
- The transceiver is limited to a
maximum of 72 parts.
- The receiver must be a superhet or
other "single signal receiver".
- Keying and muting must be included.
- Covers at least one of the
standard QRP Frequencies
- Capable of battery power for
portable use.
- Schematic w/parts list and
functional XCVR be brought (or sent) to FDIM 2010 (13-16 May 2010).
- Only one part may be an IC, all other parts must be discrete components.
- Knobs, sockets, tuning dials, copper board, power source and enclosures are not considered parts.

Propagation
is a fascinating subject. It affects us all, is discussed at length on
QRP-L, but is understood by few ! Just what does that Storm graphic
mean ? That's bad isn't it ? Er, or is it good ? What about that
K-index - or should we use the A-index ? Just what do those numbers
mean anyway ?
Paul
Harden NA5N is one of those rare individuals who really understands his
subject and has a talent for explaining in a way we can all understand.
He's also a whizz at presentation. This feature is set to become a
classic, full of hints and tips - you will become your local club's
propagation guru !

 Listen out for more activity from India. A total of twenty 20m transceivers were donated by hams from the USA and UK. The recipients are VU operators who are able to demonstrate and promote ham radio to groups such as colleges, schools and scouts.
 Pictured here are schoolteacher Vineeta Mathur VU3DXX (left) and DXer K. Leela Krishna VU3LGX (above) For more information see the report on the GQRP website |

 A new website to learn and practice Morse telegraphy has been launched - Learn CW OnlineThere are already hundreds of training programs, MP3/CD courses and practice aids available, but LCWO follows a radically different concept: While sticking to well-proven methods for learning and practice, all you need for using LCWO is a web browser! This gives the user the liberty to practice CW wherever an internet connection is available, always retaining the personal settings, scores and statistics. |
