[Elecraft] K3's 2-m module (K144XV): Need testers for major performance improvement

[Wayne Burdick]

Hi all,

We've just made a change to the K144XV firmware that dramatically  
reduces the incidence of weak receive spurs within the 2-meter band.  
Some of our customers who use SSB/CW on 2 meters had pointed these  
out, and we traced them to the K144XV's microcontroller (MCU). We now  
turn the MCU's crystal oscillator off during receive, letting the MCU  
"sleep" until you key the rig, change bands, or cross the 144/146 MHz  
boundary. It's working perfectly in our tests.

If you're using the K144XV for SSB/CW and would be interested in  
trying the new firmware, please email me directly (n6kr at elecraft  
dot com).
