[Elecraft] reflections on the WPX contest

Thu Apr 3 12:36:07 2003

I had to set back and remember some of the criticism on the MP reflector when I was listening to that...

One was, that the sub RX was not a true second RX, couldn't listen off bands, having many selectivity issues, and being unable to independently operate off band, yada, yada, yada...

A PAIR of K2's just needs an interoperability module/software to be the best SO2R platform on the planet. Could get away with only one 100W module and the internal equivalent of one of the SO2R boxes. Program the interlocks using the aux bus communication, let the contest software set the transmitter/ant.

One K2 does take care of the BASICS, not the subtleties. Two K2s bomb the competition for flexibility.

From a receiving standpoint, only thing I wish my K2 had was passband skirts equivalent to the matching 400 hz INRAD filters in both IF's of my MP, ultimate measured >100 db rejection up or down 500 hz, etc. (How COULD one improve a K2 in that direction, beyond the crystal mod?)
