[Elecraft] New K3 F/W - MCU: V 1.49 DSP: V 1.46 NR Improved. AM added

[Eric Swartz - WA6HHQ, Elecraft]

We've been busy at Elecraft Engineering this week and we have just 
placed new K3 firmware on the ftp site.
MCU:  V 1.49
DSP:  V 1.46

New Features:

Noise Reduction significantly improved. Also, NR can be used with narrow 
filters in CW mode.

AM mode added. (6 kHz Filter required.)

NOTE: AM Power control temporarily works as follows: when you set power 
to 100 W in AM mode, it means 100 W *peak power*, and 25 W *carrier 
power*.  Also, the bar graph shows peak power in AM mode. This will be 
corrected later so the display and bar graph both show carrier 
power.Manual notch frequency defaults to 2 kHz (originally 200 Hz).

See 'Release Notes'  in the K3 Update Utility for a complete revision 
history.

Enjoy! :-)

73, Eric   WA6HHQ
