The  2-Transistor Receiver Challenge proved a challenge to perform!  We had four entries, and it became evident early on that noise from nearby switching power supplies was preventing measurement of the actual receiver noise floor.  Consequently the RF to Audio gain of receiver was used as the evaluation criterion, instead of the original plan to measure MDS.  The outcomes of the event were:


Entrant                           Gain
James Scott WB0IYC    60 dB
Harold Smith KE6TI       59 dB
Jerry Wolczanski            -
Will Harris KI4POC        38 dB

The winner of the IC705 was Jeff Tucker W9TH
The winner of the FT818/A817 package was Tim McLeod
