[Elecraft] K3 Production Firmware Release (3.63)

[Wayne Burdick]

The latest beta firmware, 3.63 has been promoted to full production  
status.

Improvements will be ongoing, based on your feedback. But we have a  
high degree of confidence in this revision, and suggest that all K3  
owners upgrade to it at their convenience.

Some of the most significant changes since the last production release  
(3.14) include:

* Automation of often-used control sequences via programmable switch  
"macros"
* Synchronous AM detection with optional VFO tracking
* Incoming CW WPM display (via TEXT DEC switch)
* Improved DVR message play interaction with PTT
* Main/Sub receiver audio mixing
* Many DSP enhancements including improved NR, Autonotch, and AF  
response
* "Live" memory recall (M>V) as VFO A is rotated
* VFO coarse-step rounding
* RF GAIN linearized and S-meter accuracy improved with RF GAIN CAL  
procedure
* SHIFT control steps of 10 Hz optional for CW or DATA modes
* VFOs tune down to 490 kHz
* Lockable transmit controls (PWR, MIC, CMP)
* Automatic CW VFO offset on mode change (typically used for 6 m cross- 
mode)
* GHz transverter digits displayed
* Many new and enhanced remote-control commands

If you have questions about any of the above, feel free to post a  
question here or to email k3support.

Thanks again for your diligent testing of beta and field test  
releases. It's great to have so many outstanding operators working  
with us as we continue to refine the K3.

73,
