The ATU was in bypass. Turning it on, tuning into the DL, and then
putting it back into bypass cured it. As I said before, I don't
understand that behavior, but if it worked, I'll just accept it.

It is D-28, the big fat zener. I had two K3's running off the same supply.
I have not had any failures of this type with other gear in the past. I

at the results. Both failures happened when I

Dave,
Does the PS have a high voltage protective crowbar circuit?
I have never examined the reactive speed of the circuit (I have them in
Astron linear supplies I own) so I don't have any idea if they would be
fast enough to protect you but you would think it would trip on
overvoltage if

Rather than trying to do your proposed test, I would suggest you look
carefully at the T/R switch area first. Typical problems are diodes

Hi Everybody;
As the KUSB discussion thread continues on, I'd like to suggest an
alternative.
All motherboards, except 40 year old ones, sport a PCIE port or two. There
exists a whole
bunch of converter cards that ride the PCIe bus and convert to serial ports,
parallel ports, printer ports

...never a USB problem again!
Actually, I don't think there are USB problems. USB is a very good standard
that supports a large variety of devices and configurations. The specification
allows for simple point-to-point interface as well as hub/hosting, device
sharing, and a number of other
USB is good technology and it only needs a few little
improvements in future revisions to specifications. And, if
vendors always support backward compatibility on USB then we
are in fat-city.
USB is another example of technology ignoring marginal applications.

I've been experimenting with a serial server that resides on the LAN
here:
http://www.serialgear.com/Ethernet-Serial-Servers-NETCOM-411.html.
It's a 4-port and can handle any baud rate needed.
I've had no problems with the server, but it's not as fast as the KUSB
even with the cascaded hubs here.
I've got a note in to K3 support.

Help:
Can someone describe which features are supported by DSP. Guessing from the
block diagram, I am guessing voice compression on TX and maybe some filtering
and IF-shift on RX but I will stop guessing there.

Good Evening,

Although the PW-1 has an input for the stepped band voltage

It looks like Yaesus new FT5000 has copied the K3's architecture
The K3 will be getting a serious run for its money in the next few months.
Yaesu looks like it has done some serious competition analysis.
Features...

Not up conversion
Narrow roofing filters
99 db 3rd dynamic

Hi,
It makes me remember when Honda came to Motorbike competition in the sixties
with a copy of British engine design, but with better steels... and win the
Championship.
Certainly Yaesu engineers bought K3's and worked on it but I do not think they
can compete with the Elecraft prices.
Ah, it seems again they have rushed into production another radio. I wonder
how many design faults the first production run will have.
They are going with a 200W PA, smart move, but I wonder about the filtering and
more importantly the FW.
Wonder if it will have a USB port?
Maybe even
