Here is the answer that I sent him:

My entire K line is managed by a computer.  I use a USB board with a
pair of relays (only need one) and some specific software (shortcut on
the desktop) to tickle the ACC line to turn the K3 on when I am remote
operating.

http://www.ebay.co.uk/itm/5v-usb-relay-2-channel-programmable-computer-control-for-smart-home-new-s3-/121792206668?hash=item1c5b61974c:g:rY8AAOSwYHxWJT7L
is one example.

The software is at:
https://www.dropbox.com/s/tzngxi28uqune65/USBRelay.zip?dl=0

And naturally since I put this together, I've not had a power failure.

Rick

at QRP levels, you can easily make a relay bypass,  the relays used in the 
2m DG8 pre-amp will suffice..

Be aware - although the line out is stereo,  some sound card devices are

Todd,

I would think you are asking about the K3 or K3S line out jack.
Yes, it is a 3.5mm (or 1/8 inch) jack - it is stereo, so you should use
a stereo plug.

Re: [Elecraft] Remote shutdown of K3?

[Robin Moseley]

I use a pair of Wimo USB mains switches,  one to turn on the PSU, this then 
draws current - this then powers up all the devices plugged into the energy 
saving power strip (one with a master socket that switches power on to the 
other devices)
The second Wimo switch is wired to a mains powered relay, the terminals of 
which are wired to the power switch of a PC, so I can remotely power on the 
PC  or  shut it down. or  force a reboot if it ever locks up.


I shut down my K3 with the PS0 command,  I added this as a command macro, 
then assigned this to a button in Ham Radio Deluxe.


I power up the K3  using a small cheap 2 relay usb device from ebay that is 
wired across 2 pins on the 15 way D connector at the back of the K3.


and a small batch file that I have mapped to an icon on my PC desktop.. I 
just click on the icon and the rig powers up.


If you need any more info.. then reply to this email..

Subject: Re: [Elecraft] Remote shutdown of K3?

OK, sounds like you're off and running on your quest to get remote control.
Your recent reply suggests you have questions about other aspects of remote
control than just K3 power control. Here's what I do; there are dozens of
other options:

I use a remote power switch (webpowerswitch.com) to control ham shack
devices. It presents a Web page for access - very nice. Stuff I often
control, like the rotor controller and the DC PS, are accessible to a
normal log-in ID on the switch. I also set up an admin ID which has sole
access to stuff that I usually leave turned on - a local computer, the
modem and the router. I occasionally (very rarely) need to power cycle
those devices but I don't want them turned hard off accidentally because
then I can't get back in via the Internet. (Learned that by experience.
Fortunately, I found a neighbor who was willing to go in to the house and
restart it all!)

I have two band decoders, one for each rig when I'm local and operating
SO2R. When operating remote, however, only Rig A is accessible. I move the
Rig B decoder over in parallel with the Rig A decoder, giving me a choice
of two different amps.

I also have a remotely controlled DC relay board (Velleman K8090) that
controls power to band decoders and switches band segments on my 80M rotary
dipole. I have some other chores in mind for the remaining four relays.
That board is controlled by a program that must run locally, so I access it
via Chrome Remote Desktop to the local, always-on computer.

My antenna switching is via band decoders driven by the ACC connector band
data lines. The decoders drive a Six Pak antenna relay box through a diode
matrix that lets me use various multi-band antennas. The decoders also
drive bandpass filters but those are irrelevant when I operate remotely
because I'm SO1R in that case.

The local, always-on computer is a $200 surplus Dell OptiPlex runnning Win
XP that almost never fails, hardware or software, and self-reboots when
powered up after a power failure. It also supports the server sides of
KPA500 Remote, KAT500 Remote and PstRotatorAz. I run the corresponding
client sides on a computer at the control site. The Alpha 87A control
program has no client-server support, so I access it, like the DC relay
board, directly via Remote Desktop. (There is a third-party client-server
control app for the 87A but I haven't made it work yet.)

Lots of options - it's a challenging but rewarding exercise in system
integration.

GL & 73,

There is a line on the ACC connector that, when toggled, controls power
on/off. The RemoteRig interface boxes manage it transparently; you just 
tap

the power button on the control K3 or K3/0 and the remote K3 turns on or
off. You can also DIY with homebrew interfaces.

Zip cord is NOT good for ANY application, because it is inherently
susceptible to RFI. TWISTED PAIR is FAR better, because it inherently
rejects interference from low audio frequencies to at least VHF. In the
last few years, I've been replacing more of my DC wiring with twisted

I buy I-pad  screen protectors, then cut to size..
I also use them on the roof of my car to protect the roof from scratches 
when I use a mag mount..

Re: [Elecraft] K-Line mounting

[Robin Moseley]

Kiravan is the way forward,
http://gearjunkie.com/kiravan-expedition-vehicle-rv

But seriously, whatever you do, ensure that there is enough ventilation and 
that things can be  hidden from prying eyes.
Maybe consider using ratchet tie down straps to tie the equipment down 
securely so things don't move or get damagged if you were to have to 
emergency stop.

No need to use a Signalink with a K3..  it's audio input and output jacks 
are already isolated.

Pull the bail down and clamp to that by clamping gently to the rubber
on each side. Then you can slide a SignaLing USB into the empty spot
under the front of the K3.

Most 6m EME guys I know are using Dimension 4. Works great and in my

I have always used my K3 with paddles but today wanted to play with a 
straight key and a sideswiper. For the life of me, I cannot find out how to 
turn the keyer off in the manual. The closest I thought I had come was 
VOX/PTT  and I have also scanned through the config and menu to no avail. 
Perhaps it is just sleep deprivation preventing me from this but please 
how do I do this?

Tnx es 73,Jim W5QM

Re: [Elecraft] K3 - HRD rig control

[Robin Moseley]

Hi ,
I will be working for HRD as a European support guy.

The way it works  is .. you try HRD for 30 days for free.
If you like it, you pay once only  for the version you tried  and for 
upgrades for 12 months, you also get customer support from 3 dedicated 
support guys and developers.
If you are happy with the version you are running, and don't need support or 
updates, then  you don't need to keep paying,  you have bought the license 
for the software.


If you decide that you want the full features of the latest versions, 
support for new radios, windows operating systems etc, country list updates 
and another 12 months of the support team, then it is half the original 
purchase price per year.. so that is just under $50.

It's a good idea to check the resistance of any used dummy load, especially
one that has some age on it.

The resistance of my 30+ year old Heath Cantenna gradually reduced to 42
ohms.  This was enough error for the power meter to indicate a potential
transmitter problem.

W1GA is selling non-inductive replacement resistors on eBay for use in the
Cantenna.  I purchased one and it brought the resistance back to 50 ohms.

[Elecraft] K3 - remote power on

[Robin Moseley]

Hi folks.. 
what do people do to switch on their K3  when used remotely? 

up until a recent firmware upgrade, I could leave the K3 switched on and power 
down the PSU,  when the PSU was powered up, the K3 would come alive all by 
itself.  Shame that this behaviour has been changed,. 

After installing the latest fimware, this no longer happens,  I remotely shut 
down the PSU, but when powering back on, the K3 stays off.  Reading the manual 
shows that  I could provide a ground to pin 8 of the ACC port to power up the 
rig,  am looking for a low cost way to do this,  so far I am thinking of a 
cheap USB relay device that I can send a pulse to from a batch file.

Re: [Elecraft] K3 voltage indicator

[Robin Moseley]

Measure the voltage inside the K3,   at the powerpole..   you may need 
thicker DC lead or clean the fuse contacts.

Subject: [Elecraft] K3 voltage indicator

Folks

I suspect that may have been asked before, so forgive me if it has, but I
need to know what the typical voltage readings are observed (on the K3
voltage indicator) when
a) On receive?
b) With say 10w TX power?
c)  With 100W TX power?

Using a DMM, I can see that my 13.8volt linear PSU seems to drop 0.1volt
when going from receive to the 100W TX level - yet the  display indicator on
the K3 goes from 13.7v (receive) to 13.3v (10W) to 12.9v (100W) Is this
typical?
