[Elecraft] KX2 - updating firmware

[Don Wilhelm]

Pete,

Fine that you are using an FTDI USB to serial adapter - but what is the 
connection from the DE-9 conncetor on that adapter to the KX2.  If it is 
the KXSERa cable, then it should work fine, but if you have wired your 
own DE-9 to 3.5mm cable, then check it to make certain it has the 
correct connections and has continuity on all 3 of the used conductors.

In other words, if you have made your own Serial to KX2 cable, check it 
first.
Set the KX2 RS-232 to 38400 and use KX2 Utility to attempt to connect.

73,
