North American QRP and QRPp builders and operators are now invited to join in the venerable Minimal Art Session (MAS) on May 13, 2010, 9 PM to 1 AM LOCAL TIME (in North America only).  This "do the most with the least" event is truly more about Art than Contest.

Lutz Gutheil, DL1RNN, has sent the approval for North America to submit logs for this event.  Last year, for the first time, logs were submitted from the US and Canada.  So, the MAS is growing from its original 12 countries, and is starting to become an even bigger International event.

The MAS is one of several events of the QRP-CC, (QRP Contest Community) that was organized by Dr. Harmut "Hal" Weber, DJ7ST, a recent SK. http://www.qrpcc.de/

To find out what makes the MAS special, check out the session challenge below.  (This information is also available at http://www.qrpcc.de/contestrules/mas/index.html Click the English button in the upper left box.)

[The following was extracted from the QRP-CC site URL, above]

Challenge:

• Contacts have to be made using rigs built by the operator himself, and from as few components as possible.

Date:     

• May 13th, 2010 (Ascension Day) ;  1900-2300 UTC [North American times are as shown above]      

MODE:     

• Single Op CW, Output < 5W or Input < 10W

BAND:     

• 80m CW-Band     CALL: (cq) mas de...

CLASS A:   TX+RX resp. TRX consisting of not more than 100 components

CLASS B:   TX consisting of not more than 50 components,  RX as you like

EXCHANGE: 

• RST/Class and number of components, e.g.: 559/B25 (feel free to exchange name and small talk)

QSO-Pts:  

• A QSO scores 1 point. 4 points will be awarded for a QSO with another MAS-stn whose log has been received.

BONUS:    

• You will get bonus-points in percentages if you stay below the limit of components permitted for your class, e.g. a 50% bonus will be added to your final score if you only use 25 components (instead of max. 50) for your TX in class B or only 50 parts for your TRX in class A (instead of max. 100). Correspondingly 90 parts in class A or 45 parts in class B would mean a 10% bonus.
            

REMARKS:  

• Components will be the following: Resistors, capacitors, coils, diodes, transistors, tubes, crystals, ceramic resonators etc.  Any selective network in the TX output stage will be counted as if consisting of 3 components. For a better suppression of harmonics you are free to use more components - they will not be counted.  IC's are permitted as long as YOU(!) can give a specification of HOW MANY single components are integrated. Plugs, connectors, knobs, fastening material etc. will NOT be counted. This also applies to power supply, headphones, speaker, key, antenna, switches, relays etc.

LOGS:     

• Must contain UTC, call of stn wkd, RST sent & rcvd (see EXCHANGE).  Please give your callsign, full address and possibly PR-mailbox.

IMPORTANT:

• A circuit diagram of rig used with NUMBERED (= counted from left to right) components has to be enclosed (and an IC specification if used)! (It is not necessary to send a circuit diagram for a second time, or if the same equipment has been used in an earlier QRP-MAS)

DEADLINE:

• Within 2 weeks after qrp-mas by mail to: 
•

To see an extensive list of Transmitters, Receivers and Transceivers that have been used in previous MAS sessions, go to http://www.qrpcc.de/contestrules/mas/index.html and click on "Projects for MAS (English)" in the upper left corner.  Or take a look below.

You will note that lots of these rigs came from articles in the GQRP club's Sprat magazine.  Kanga-US sells a CD of Sprat back issues if you want to get more info.  http://www.kangaus.com (click on Books then GQRP)

Let me know your thoughts on this event.  Anything that combines Homebrew with QRP gets my attention.  I look forward to working you on May 21.
