[Elecraft] Important K3 Firmware Update, MCU rev 1.69 (WAS 1.68)

[wayne burdick]

A customer just alerted us to a firmware issue in CW mode. When using 
external keying (handkey, computer, or external computer) or the 
internal keyer at over 40 WPM, the K3 may switch to the wrong receive 
VFO frequency, crystal filter, and/or preamp setting on key-up. It 
appears that this behavior has been present since MCU revision 1.62.

While these symptoms should occur rarely, we recommend that everyone 
update their K3 MCU firmware to revision 1.69. (1.68 had just been 
released yesterday.) Sorry for the inconvenience.

73,
