LEDs are low voltage DC current driven devices, and those in the K3 are
easily driven from the internal supplies. LED bulbs used in residential
lighting each have a power supply in their base that has to efficiently
drop the 120 VAC source down to low voltage DC current, and that pretty
much
Jim,
But Joe, you are fixating on a single specification, which is only
one part of what establishes the cleanliness of a radio. On CW and
FSK, there is the keying waveform, and on all modes there is phase
noise.
IMD is not an issue with CW or FSK (or JT65/JT9 for that matter) - they
are
Not everyone can get to Dayton but that does not mean you should not get the
same great service and value as the /Hamventioneers/. Because I cannot
display and sell heatsinks at Dayton, Nick / N3WG of Pignology LLC has
agreed to host the highest performance Cooler KX Plus and a stack of product
You are wise, Ted, to be cautious about this.
As you implied, it is not the LEDs themselves but how they are driven.
LEDs are current driven devices and, for a given intensity, are typically
driven by a constant current source. In the case of a panel LED in a K3 or
whatever it is easy to do

The K3 may be cleaner than low end 12V/100W rigs like the Icom 706mkIIg
