11th Q R P - M I N I M A L A R T - S E S S I O N
QRP-CONTEST-COMMUNITY (qrpcc) 15-March-2011 c/o Lutz Gutheil, DL1RNN Bergstrasse 17 D-38446 Wolfsburg Germany e-mail: email@example.com web: http://www.qrpcc.de 11th QRP-MinimalArt-SESSION (TNX to Eddi, DK3UZ, for translation) "IT IS VAIN TO DOWITH MORE,WHAT CAN BE DONE WITH LESS" (William of Occam, philosopher & theologian, Oxford/Munich 1290-1350) (an early QRPer?) To reach one's goal with minimal consumption of materials demands a feeling for essentials and encourages the art of self-restraint. In the spirit of an active -and winking- dealing with elementary ham-radio the QRP-CONTEST-COMMUNITY invites you to take part in the 11 . Q R P - M I N I M A L - A R T - S E S S I O N Â ( qrp-mas ) -------------------------------------------------------------- This is a proposal of new MAS rules from 2011 on. Challenge: Contacts shall be made using simple rigs built by the operator himself, and from as few components as possible. Date: 2nd June 2011 (Ascension Day), 1600-2200 UTC -------------------------------------------- MODE Single-OP CW, output <5W or input <10W QRG: 80m-CW-subband, recommended: Around 3560 kHz 40m-CW-subband, recommended: Around 7030 kHz / 7160 kHz CALL:"cq mas" or simply "mas de" CLASS A: RX+TX or TRX consisting of not more than 100 components CLASS B: TX consisting of not more than 50 components, Â RX as you like CLASS C: RX+TX or TRX consisting of not more than 100 components, max 1 integrated circuit! EXCHANGE: RST/Class and number of components, e.g.: 559/B25 feel free to exchange name and small talk) QSO-Points: A QSO scores 1 point. The adjudicator will award 4 points for a QSO with another MAS-stn whose log has been received. Points from both bands will be added. BONUS: You will get bonus-points in percentages if you stay below the limit of components permitted for your class, e.g. using a TRX made from only 50 components in class A (max. 100) will boost your final score by 50%. The same goes for a TX of only 25 components in class B (max. 50). A TRX made from 80 parts or a TX made from 40 parts will yield a bonus of 20%. Components are resistors, capacitors, coils, diodes, transistors, valves (multiple sections count per section, e.g. ECL86 = 2), crystals, ceramic resonators etc. Commercially made filters count one per pin. Any selective network in the TX output stage will be assumed and counted as a 3 parts PI filter. For a better suppression of harmonics you are free to use more components - they will not be counted. RX input networks will also be counted as 3 components. These parts do not count: Plugs, binding posts, knobs, sockets, housing, switches, relays, power supply, headphones, speakers, key, antenna, etc. Multiple coil windings on a SINGLE former count as 1 part. ICs are permitted in classes A & B as long as YOU(!) can give a specification of HOW MANY single components are integrated (e.g. LM386 = 20). In class C a single IC is permitted. All connected pins count, but ground and supply voltage pins only once. Participation in class B is possible of course, if the RX part of a TRX uses more components than permitted for class A. LOGS: Columns: UTC, call of station worked, sent & received exchange. You are required to include a circuit diagram of your rig with parts numbered from left to right, and an IC data sheet if applicable (only in class A and B). Please make sure to include the circuit diagram, I don't have any of Hartmut's file. Deadline: Logs should be sent not later than a fortnight after the QRP-MAS to Peter Haensel, DL6CGC Hoetenslebener Str. 15 Barneberg 39393 Hoetensleben mail: "mas at qrpcc.de"
