Tom,
Those show promise. Keep us posted on the results of your experiments.
What about latency? Does it work with QSK CW? How to handle the audio
channel?
To successfully work with existing applications, they would have to be
addressable as a com port to any computer on the network.
Since
What you have for trade?
I got one for a Christmas present when I already had one in the
collection of mods, upgrades that I was accumulating for my #1239's
A/B board upgrade project. I don't know about any since then
upgrades. You'd have to research that with the Elecraft or their tech
support.
Sorry, did not mean to post this to the reflector.

I have had experience with Lantronix products and the Ethernet to

these devices connecting Laboratory devices (chemistry - Blood

Because of the buffering done on the input side, most Enet - Serial
adapters have worse basic transfer rates than USB adapters have.
Datagrams may have only 10-12 characters in the payload.
Try your unit with PortMon, and you'll see what I mean.
The buffering of single characters also causes
Before I retired I used dozens of Lantronix ETS terminal servers to
control network devices in a nationwide network. Bulletproof units.
We were able to make serial ports on remote devices look like they
were local. Actually we were also able to modem into one serial port
and out another.
When I built my K3, I was not able to get a tight enough fit between the
DSP board and the front panel to keep that thick washer (that goes over
the phone jack) from rattling.
I pulled the DSP board this morning to send in for the upgrade, and
would like to fix the washer when I re-install it.
I have also saved a quite number of power pole connectors with small jeweler
pliers like Phil states.

Hi Matt,
Certainly. and not the point.
Seems hard to use the USB adapter when my computer is next to me and the
Ethernet to serial device is across town or across the country. You can
get Ethernet based USB servers but they have the same latency behavior.
If you are trying to operate a

Lantronix Serial servers. Solid but expensive from a hobby
budget point of view. But if you want the best, you cant go
wrong with them.
In a former job, I designed a system that ran an entire
complement of broadcast master control devices
Hi Chris,
I would not worry. Its normal to see a little cracking of the conformal
coating on cap leads when you bend the leads. As long as its not
cracking along the main body of the cap you should be OK.
Also, the 2N7000 is probably OK. 6mm is usually specified to provide
clearance for other

Hi Tom,
Sorry, maybe I didn't say some of what I should have. My reasons for
using Ethernet are similar to yours, at least when it comes to the K3.
IP can be routed, where USB and serial (alone) cannot. This gives us
the option of remote operation, the main goal. Whether for a K3 or
other
Dear Bill,
Thanks a lot for the advice. I am much happier now.
don't worry about the cap, the covering will often crack and even
break off as you straighten the leads or 'stuff' it on the
board.
Good to know that there is no reason to worry. I will take your
advice as write down my
Hi Matt,
I had the same need for serial ports but discovered I could get
inexpensive PCMCIA serial and parallel port cards that worked exactly
like built in serial ports or the docking adapters that fit my ThinkPad
laptops. So ditched the USB converters.
Once I get to go set up the TS-480 out
I imagine latency to be small, possibly negligible if one uses a microwave
link line of sight. It's a dream I have to put my K3 in a remote spot with
line-of-site control via radio (amateur radio or possibly 2.4GHz
licence-free). Unfortunately I think there are licensing issues over here
Hi Eric,
I would not worry.
I'm much relieved and thanks for the quick answer!
Thanks for a fine product.

Hello,
I just completed KRC2, initial test in page 15 of manual was successful.
Now completed final assembly and connect to K3 using AuxBus, turn
on 12V, LED does not turn on, K3 does not recognise KRC2.
Later I realised I should connect GND on pin 5 of K3 side, instead of
pin 6, which KCR2
From what I read in the K3 manual pin 6 is DIGOUT0 which the manual
states will be 0V when you select TRN or HF-TRN and are in low power
mode. At all other times that pin is Hi-Z. So no connecting to that
pin would not have broken anything in your KRC2.
Looks like the only LED in the system is

Don't forget that the transverter option (KXV3 or KXV3A) also gives
you the ability to use a separate receive antenna, especially useful
for low noise receive-only antennas on 80m and 160m. Also, it will be
needed if you intend to eventually add the P3 or other panadapter.

Kazu,
Try re-doing the tests on page 15 of the KRC2 manual. If those tests
are not successful, try loading the KRC2 firmware (download available
from the Elecraft website). You would need the KRC2 Download Program
loaded onto your PC and the actual firmware file to be loaded from the
PC -
It appears that the MCU is not getting power. Go back and recheck your solder
joints - something is definitely amiss. Go through the voltage check table to
make sure the voltages on the important pins (usually the power pins) are
correct.
Note that you probably will not be able to load
Most networking involves some degree of character-level latency. In
general, data are arranged in packets (or frames), each of which
contains some number of characters or bytes, as payload.
If data to/from is buffered, it takes time to accumulate enough data
