The K2ZRO Memorial Station Engineering Award is an award for station excellence in receiving. Periodically during the year, W5ACM, Andy MacAllister will conduct this test. He transmits a series of 5 digits at becon strength in CW on AO-13. He will then reduce his power by 50% or 3db. He transmits another series of 5 digits. He will continue to reduce power by 50% until he is transmitting at 30db below beacon strength or level A. You attempt to copy the 5 digits to the level you can hear.
This award is no longer available as AO-13 has long since met its demise.
