[Elecraft] K3 Beta Firmware Revision 2.02

[Nick J. Sinanis F5VIH/SV3SJ]

Interesting, since MCU version 2.00 already,it is possible to use the 
front panel buttons RX ant, PRE, ATT, XFIL AFX while in TX Mode!
The filter settings cannot be yet changed however.

Very useful addition, however no feedback is provided when a key is 
pressed during TX - it all happens when the rig passes in RX mode. I got 
surprised to hear all of a sudden a relay click when my K3 passed in RX 
mode. It was the RX Ant relay after I had pressed the RX Ant button 
during TX mode :-)

Thank you once more Elecraft!
