As long as Elecraft continues to make kits (and I certainly hope they do), printed manuals will be essential. I just can't see clicking on a box with my mouse to indicate that I have completed a step. Printing a 100+ page pdf file isn't very practical either. 73, Bob N7XY On Jun 11, 2012,

Bolometers work at pretty low (milliwatt) power levels and you would need to use an attenuator, which could add some error to the measurement. Hewlett Packard made the HP434A Calorimetric Power Meter, which could measure up to 10 watts by matching the temperature in a load with that caused by

The nice thing about the KDSP2 is that you can tailor the settings to do different things when required. I have had good luck reducing atmospheric and similar wideband noise, effectively lowering the noise floor (sometimes to the point where, in the lack of a received signal, you can hardly
