25th QRP-MinimalArt-SESSION
"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
25 . Q R P - M I N I M A L - A R T - S E S S I O N ( 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: 29th May 2025 (Ascension Day)
40m 1400-2000 UTC
80m 1600-2200 UTC
--------------------------------------------
Next: 14. May 2026

25. May 2028
MODE Single-OP CW, output <5W or input <10W
QRG: 80m-CW-subband, recommended: Around 3560 kHz
40m-CW-subband, recommended: Around 7030 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, 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. All stations can be worked, also stations
not participating in the QRP-MAS.
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
