[Elecraft] K3 Setup Failing

[Don Wilhelm]

Brian,

Check your com port settings - the K3 normally connects at 38400 bps.  
You indicate 4800 bps, so perhaps the computer port speed is 
'throttling' the data.  If you are using a USB to serial adapter, a low 
speed like that can create errors in the data stream because the 
responses are not fast enough.  Real serial ports do not usually have 
that problem, but USB to serial adapters often do.
