[Elecraft] Battery

[Mike Harris]

After twelve and a half years the RTC battery in my K2 KAF2 finally 
croaked.  Not bad going.  Makes me think that as a precaution I should 
also change the same in my redundant K2 KDSP2 (10y) and the K3 (6y) the 
next time I have the sub RX out.

Note: the KDSP2 is redundant only because I've decided to keep the K2 as 
an all analogue signal path to complement the hybrid analogue + digital 
K3.  The KAF2 provides the always in line LPF that the K2 needs to kill 
off receive audio hiss.  When first plugged in the improvement in 
listening pleasure, particularly on SSB was astonishing.
