[Elecraft] K3 utility problem

[Dick Dievendorff]

Sounds like a flakey connection of some sort. RS-232 connector jack screws
reasonably tight? Anything moved lately?  Can you simplify the cable path
from PC to K3 by (temporarily) removing any USB hubs, extension codes, P3s
etc and connect the USB to Serial adapter directly to the K3.

If it's still flakey, can you borrow another USB to Serial adapter long
enough to test that?

I have seen USB to Serial adapters degrade over time, but not often.

Subject: [Elecraft] K3 utility problem

After doing downloads with no problems for four years I'm now running into a
problem.  Using K3 utility v 1.12.3.28 the utility won't hold a connection
to the K3.  No matter what the connection speed, the connection is
interrupted.  Sometimes it gets as far as showing which version of the MCU
is installed.  Sometimes it reaches the FPF version.  Sometimes it even gets
to DSP1 and 2.  But, when I click "Send all new firmware to K3" I get a "no
connection" error.  At the bottom of the utility box it continues to say
"Attempting to connect to K3 on port Com8 at x speed."

I'm using Elecraft's USB/RS232 cable and that cable works fine with my
logging programs, (none of which are open and they don't seem to be
conflicting).  My OS is Windows XP.

Any thoughts?
