The Manly Warringah Radio Society (MWRS) invites you to participate in our
Inaugural Postcode Challenge. This is a fun contest and is not to be taken too
seriously. So dust off your rig, get your antenna in the air, try out some different
modes and make some new friends.
When is it?
The contest will run for 14 hours on Saturday 16 th September 2017 commencing at
0000 UTC and finishing at 1400 UTC (10:00 am to midnight AEST).
Postcodes are allocated to geographical areas and used in Australia to efficiently
sort and route mail within the postal system. All postcodes in Australia have four
digits and are placed at the end of the address.
Postcodes have come to have other and varied uses, and it logically follows that the
challenge here is to contact other amateur radio stations in as many different
postcode areas as possible.
The winner of the competition will be the person who collects the most points during
the day of the competition. The scoring has been kept as simple as possible and, in
order to add an element of fun to the occasion, bonus points will be awarded as
The President / Vice-Presidents of MWRS will be adjudicators.
All amateur frequencies and modes including repeaters may be used.
Portable operation is permitted and encouraged.
Maritime operation is permitted using the postcode of your nearest landmark.
Scoring is the same as for portable operation.
A contact will be the exchange of callsign, signal report and postcode
Logs are to be submitted using the Postcode Challenge spreadsheet. (see
