Greetings all,

 

Is it possible to be able to power  on and off the KAT500 through the K3?

 

Best regards,

Short answer: No.

From the KAT500 manual:

"Connect to the station 11 to 15 VDC power supply with the white striped lead to the positive terminal. Do not take this power from the K3’s 12 VDC output connector, even if it has been upgraded for 1 Ampere.”

Hope this helps,

But you can via the utility, if that can apply to your needs.

Re: KAT500 question

Jerry
Thanks Rick and John,

I asked the question because I have just bought the K3/0 Mini remote and I would like to be able to turn ON and OFF the KAT500 when I am about 1 thousand miles away. I know that I can do control the on.off on the  KPA500 by connecting the  8 pin line on the 15 pin ACC connector on the KPA500 to pin 11, I was hoping that there would be an undocumented way for the KAT500.

Re: KAT500 question

Jerry
In reply to this post by John E Bastin-2
Thinking about the answers already received, allow me to ask the question in a different manner. Is it possible to control the KAT500 power on\off via programming macros in the K3 PF2 button?

Best regards,


Jerry, W1IE

Re: KAT500 question

Dick Dievendorff-4
In reply to this post by Jerry
Not thru, but if you control a power supply from the K3, that will do it. I bought but haven't yet installed a West Mountain Rig Runner model 4020S+ that switches power to other outlets when one "master" device is switched on.

Or use the K3 back panel RCA 12V connector to activate a relay that provides power to other station devices.

The KAT500 can at times draw a bit more than the 500 ma or 1A provided by the K3 12V RCA connector.

No. And, the KAT should be running when you turn on the K3(S). Mine stays on all the time.

I wonder if this "Do not take this power from the
K3’s 12 VDC output connector, even if it has been
upgraded for 1 Ampere" is because, at one time,
the KAT500 had to be powered on before the K3 was
powered on?

Not really. I totaled the current draw of all the relays when pulled, added the microcontroller current and it was a tad over an amp.

You don't have to play with that 15 pin acc. or anything else. There is
a program on the Elecraft site that you host to the control site. Just
pecking a button in the program will turn it on/off. I used it for 3
mos, 1200 miles away from here.

Re: KAT500 question

Barry Baines
In reply to this post by Jerry
Jerry:

Here’s an approach that I use for K3 remote operation (including control of the KAT500) that you may find appropriate for your needs as well.  

I use my K3 almost exclusively through the K3/0-Mini.  The radio site is in Southeast Georgia and my primary residence is in Massachusetts.  I’ve configured my HF station with the following:

1.  K3/0-Mini controls the K3 through Remote Rig’s RRC-1258Mkii devices.

2.  The Remote Rig RC-1216H provides a web-based control of the KPA500, providing a web screen that looks like the front panel of the KPA500, allowing me to control the amplifier as if I were in front of it without using a PC in the shack.  

3.  For the KAT500, I’m using a Lantronics Serial-to-Ethernet converter that allows me to run Elecraft’s KAT500 Utility software on a computer in Massachusetts controlling the KAT-500 directly in Georgia through the KAT500’s serial port.  The Elecraft software provides all of the status information of the KAT500 plus control of all functions, such as turning the unit on/off, setting which of the three antenna port to use (e.g. dummy load, yagi, etc.), bypassing the tuner, noting the SWR of the antenna/band I’m on when transmitting, etc.  

A prime reason for taking this approach is so I can ensure that the KAT500 antenna port selected when shutting down the tuner is port 1 which has a dummy load attached.  Since I’m not at the radio site, selecting the dummy load provides at least some additional isolation for the KPA500 and K3 between the Polyphaser attached to the grounding system at the ground plate entrance where all coax cables and DC lines (rotor control, Preamp on/off, etc.) enter the shack through various Polyphaser devices.  A dummy load also provides an appropriate load for testing power output before going ‘live’ with the Elecraft software providing real time measurement of performance.

4.  The Orion rotor’s serial port is also fed through the Lantronics Serial-to-Ethernet converter (it is a five port device; I’m using two), allowing me to run PstRotatorAz.exe to control the rotor directly from Massachusetts.  

5.  I can turn on/off devices in the shack using the West Mountain Radio R4005i which allows web-based control of up to five separate devices by providing a 12 VDC output to on any of the five available ports.  The Orion is turned on/off through this device using West Mountain Radio’s PWR AC Controller attached to Port 1, which is a device using 12VDC to switch 120VAC. Anderson Power Poles provide connections to the R4004i’s five ports and the PWR AC, and each of the five ports of the R4005ican be individually configured for when the ’soft’ fuse on each port is opened.  

There are some network configuration setups required at the radio site’s router, such as configuring port forwarding appropriate ports to various devices to make this work, plus DDNS to allow for connection from the outside world (WAN) without having to know the external IP address at the radio site.  

An alternative would be to run the KAT500 software on a computer in the shack and then connect to that PC through remote access software such as Team Viewer or LogMeIn.  This approach would probably be simpler to set up than what I’ve done (no setup of port forwarding within the router), but  prefer my approach because PCs can fail and require reboot which can be problematic if you’re not at the site and won’t be there for some time.  Note that I don’t need any PC to be on in the shack to have total control of my HF Station.  

Overall, I’m very satisfied with this approach. I hope in the future that Remote Rig will provide a firmware update to the RC-1216H to add the ability to control the KAT500 through a web interface just as is done for the KPA500.  Such an approach would eliminate the need for a Serial-to-Ethernet converter as well as allows control of the KAT500 with a iPhone or iPad.  

Hope this helps,

Barry Baines, WD4ASW

Re: KAT500 question

markmusick
In reply to this post by Nr4c
This is no longer true. That problem has been fixed.
I don't know what firmware version it was that eliminated the need to have
power to the KAT500.
Even when the problem existed, it only required that there be 12 Volts at
the KAT500 power connector. It did not require the KAT500 to be powered on.
I solved this by having the K3 and KAT 500 powered from the same power
supply. I could power on the K3 before the KAT500 with no problems.
With the fix the problem is moot.
On Field Day we operated the K3 and KAT500 from separate power supplies and
turning on the K3 before turning on the KAT500 was not a problem.

No. And, the KAT should be running when you turn on the K3(S). Mine stays on
all the time.
