[TOEC] [CCF] SAC CW 2012 RESULTS PUBLISHED

[Mats Strandberg]

Still thinking we are trying to catch mosquitoes while letting big
elephants slip through our nets...

Best way in to avoid band edges and limits with 1 kHz for CW and 3 kHz for
SSB (depending on LSB or USB). Then you have required margin usually for
frequency accuracy of most rigs.

Frequency violations are important to keep track off, while I still claim
it is better to focus on developing a code of honour for operators in
contests, where main issues are to work unassisted when claiming to do so -
and keeping powers levels within the stipulated classes of the contest and
below the allowed powers of each nation.

Why try to complicate things and just try to pick the small mosquitos?

Amazingly quiet from the participants of the forum related to power
issues... I did not expect the opposite, but silence is also an indicator
of the situation.

73 de RM2D, Mats
