All,

I'd be willing to bet nobody in this country or Canada was tested over 
how to setup a LAN or Ethernet communications on their Ham Radio exams, 
and I'd bet there are a few guys on this board who could teach us all a 
thing or two about radio.


RS-232 just isn't that hard and one of the worst LAN fur balls I ever 
had to fix was caused by a couple of jabbering NIC's. I access all of 
our Routers and Switches with a laptop ,USB to RS-232 adapter and 
telnet. It's just not that hard.


The only thing you get when switching from RS-232 to Ethernet is bandwidth.

Re: [Elecraft] Seeking input on KPA1500 station

2017-06-18 Thread Michael Walker 
Dave et all

I still believe that Lan/IP is the way to go.  The way Flex is doing it
does not require it to be on your active network.  It works very well in a
peer to peer connection and it requires zero configuration.  Significantly
easier than configuring RS232.  The KPA500 software works well, but it have
to have some understanding of IP communication and RS232 configuration to
ensure it works.  I use it every day where the Server side of the KPA500
software (and the W2 for that matter) are running, but I then do an IP
connection to that software so I can see it from my main operating station.


1 Lan cable into the Flex radio and to the Amp at the same time.  But, if
you want it on your network, then you can do that as well.  It is really a
no brainer.

Personally, I have spent so much time debugging RS232 problems for people
and that really surprises me.   RS232 is not as plug and play as LAN is.
Today's people clearly understand it better.

Yes, I guess you can have AV issues, but that is more of the exception than
the norm.  Yes, if you mark all your NIC cards as Public, you are going to
have to white list everything, but there is no real requirement to have the
firewall turned on for machines behind your routers unless you are a belt
and suspenders person.  Certainly having it on on the Ham machines is not
wrong, but is another level of confusion.

A LAN based communications platform opens up the ham shack integration to
an entire new level.   I keep saying over and over that Ham Radio as a

Unless you have some of the popular AV/AM software packages running,
that will actively prevent such things.

Don't ask how I know, but we have LAN equipped kit at work, where sadly
due to the AV/AM security software that we have no visibility into, it
intercepts and blocks many LAN protocols and such, that it doesn't know
about.

We have to get IP addresses white listed for them to work, and even then
there are issues.It's easier to use an old PC that has been stripped
of all such nonsense, we just make sure it's never used on the office
LAN itself these days.

That, and if there is a LAN port, you usually need a way to control it's
settings (IP address, Mask, default gateway etc) else you need to use
RARP to find it's IP address from it's MAC address.   As per the popular
(and very good) Lantronix product line.   But finding an AV/AM package
that will not scream blue murder when it sees RARP being used is another
stumbling block.

Then, there are the potential security issues.  How many LAN equipped
bits of kit, have had their IP stack fully vetted and tested to behave
correctly under all situations, plus the products own firmware needs to
be written with security in mind.

There's enough chaos already from consumer IoT things, from light bulbs
to TV/PVR boxes, we don't want similar nonsense in the shack, nor want
Elecraft to become yet another IoT bot target.   (Google "mirai botnet"
for an example.)

RS232 works, & is difficult to remotely hijack for malicious purposes.  
USB connectivity works too (often emulating legacy com ports etc) and is
easy to implement.   There is nothing "Wrong" with LAN ports for control
and I/O etc, but in this day and age, it has to be done perfectly, or
not at all.  And doing that is not trivial!

Plus, any "PC software" will need to be cross platform too.  NOT just
Windoze.   (A Java app perhaps?)   Or, fully disclose and publish the
protocol used by the "device" so the rest of us can use it.

Plus, will users who don't even understand simple serial port settings
even get their heads around LAN address settings and such, plus some
people will then want WiFi because they don't like wired LAN systems.  
Where do you stop?

Oh, and EMC issues.  QRO RF and LAN systems often don't co-exist well,
also LAN cables can, and often do leak QRM, so you'll be needing STP
cables, not exactly low cost.  Again, I know this from first hand
experience, at work and play!

Why not use Optical fibre links, and simple RS232 like
commands/responses.  RF proof, no radiated EMI, no ground loop issues,

Just my take on it.

My 2 cents.

Drop the RS232 line totally and have only an IP / Lan connection.  This
will solve so many connectivity issues.  With a PC client software, it will
just find the amplifier.

This is what other Amp vendors are now doing and it is litterly plug and
play.

The next K-radio should also be LAN aware.

Would be good if "remote-on" would be possible as well. Possible options 
include serial command, a dedicated I/O-line, or control lines of a serial 
port. 

Such a setup could also be a nice basis for remote operation, including dead 
man switch type setups, power sequencing and so on.

Going a bit outside the scope of the post I'm replying to, such a sequencing 
could also be useful for a later setup of a KPA1500, and a "headless" box 
similar to K3/K3S, with a RemoteRig-type control.

Small controller unit to power on both the KPA1500 and the headless box as 
requested by RemoteRig interface, then operate as normal. Allow controller unit 
to include a timer, disconnect on lost connectivity to the RemoteRig, etc.

Couple of remote GPIO, to allow for sensors based on users need (someone 
entered the room? Ambient temperature? Temperature at amp chassis?), and things 
are starting to look very good for remote users.

[Elecraft] Seeking input on KPA1500 station configurations

2017-06-15 Thread Dave AD6A 
Wayne/Eric,

 

Maybe too late, I know, but I've been thinking about my ideal desk setup for
HF/6m/2m and have come up with the following list of wants for the KPA1500
system:

 

I'd like the KPA1500 power supply consumption to be less than 1W when the PA
is "off".

 

I'd like the power supply to be able to be turned "on" by a single button
push on the front panel of the amplifier (on the desk). That is, the
less-than-1W power supply, via a push-button, operates an AC contactor in
the KPA1500's power supply unit (under the desk) to turn on the main power.

 

I'd like the power supply to be able to provide an extra clean 25A (30A?) at
13.8V via several sets (4?) of 30A Anderson PowerPoles on the back panel so
that I can run my whole HF station (K3s + P3) from just the one KPA1500
power supply and I'd like to be able to turn the power for this extra power
supply on/off from a push button on the front panel of the KPA1500 (on the
desk) or simply have it turn on/off with the main AC power contactor.

 

Other wants (not KPA1500): I'd like Elecraft to make a K3s/P3 matching
stereo speaker that is 17" wide x 4" tall x 10" deep, so that it sits neatly
underneath a K3s/P3 combo. I'm actually making my own right now, but I'd
prefer an Elecraft "branded" one.

 

Thanks for listening!

 

Cheers es 73,

Dave AD6A

Not sure if this has been suggested or not, but .  .  .  .

If you have plenty of room -- and you're not doing anything else(!), I 
think it would be interesting to have a PTT counter - a count of how 
many PTT closures during its lifetime.

Re: [Elecraft] Seeking input on KPA1500 station configurations

2017-06-13 Thread Michael Zabel 
This would be a great help!

I just know myself, and sooner or later I will TX full power into the
untuned antenna/tuner.

Though the rigs rx performance is far from ideal, the current setup has me
pretty spoiled. The Icom trx will initiate a tune of the AH-4 at low power
if I have changed frequency more than 1 %.

The JC-4s I have on order works on the AH-4 protocol too.

Just looking to add an amp to the station when I upgrade and the Elecraft's
have my eye.

Mike:  The "Tune" connector on the back of the KPA1500, like the KAT500,
can be used with an ICOM transceiver to cause a transceiver TUNE button
press to start a tune cycle for the KPA1500's ATU.  No AH-4 is involved,
the AH-4 is designed for the 100-watt category.   The ICOM transceiver
sends and receives the same signals as it would with an AH-4.  But it's the
Elecraft ATU, not the ICOM AH-4.

If you want to use a remote tuner, it should be capable of handing the
amplified output, the ATU tuning negotiation should be between the exciter
and remote ATU (which could well be the AH-4 protocol), and the KPA1500 can
be used in its ATU bypassed configuration.

We will be on the lookout for ways for the KPA1500 to help with this, like
bypassing the amplifier when ATU tuning.

Hello group,

This is my first post here, but have been reading the mail for a while.
I currently do not have any Elecraft gear, but have built a K2, and owned
KX1 and KX3.

I am considering upgrading my station in the near future and am interested
in the control possibilities of the KPA 1500.

I currently use an AH-4 for remote tuning of a non resonant vertical dipole
that I use on the upper bands, and have on order a Stockcorner JC-4s
kilowatt remote tuner to replace the AH-4.

To the topic here, I am interested in the mention of a connection for the
AH-4 on the KPA 1500 and and what it's use would be given the mismatch of
the power ratings of the two devices?

Now on to the station setup I can imagine...

It would be useful in my station setup if the KPA 1500 could sense a
frequency change and initiate a 10-20 watt tune cycle with the JC-4s before
going back to online status. Ideally the KPA 1500 could do this without
communication with the exciter making that interface universal.

Alternately, with the K3(s), any tune initiation from the transceiver could
cause the KPA 1500 to initiate a tune cycle with the JC-4s with the KPA
1500 in bypass.

Or even more ideally, Elecraft comes out with a fully integrated remote
tuner to match the KPA 1500 for those of us who need the wider matching
range in our urban antenna restricted situations.

A wide range tuner in the shack would also work, but then you would only
want to do that with some very low loss coax like 7/8 Heliax.

Thanks for the opportunity to give input and for the example you set as a
company.

Re: [Elecraft] Seeking input on KPA1500 station configurations

2017-06-13 Thread Bob Wilson, N6TV 
Wayne,

Sorry for the delayed response.  What seems to be missing from the KPA1500,
compared to the Alpha 87A, is a keying OUTPUT on an RCA phono jack.  If
it's too late to add another jack to the KPA1500, perhaps the REM jack
could be reprogrammed via firmware to do this function, instead of remote
power on?  Note that it also has to work when the amplifier is OFF.

From the Alpha 87A manual:

"KEY OUT – Provides a pull-down to ground (through 47 ohm resistor) which
follows the line connected to the RELAY jack when the amplifier is ON and
in OPERATE condition. When the 87A is in STANDBY or OFF, KEY OUT is
directly connected to the RELAY jack by a closed relay contact in the
amplifier. Useful for special T/R hook-ups when amplifier is used with
exciters having poor T/R sequencing."


Some folks have to send keying input to the amplifier, and let the
amplifier key the radio, to prevent hot switching.  It may also be useful
in SO2R lockout systems.

In my shack, I currently wire two of these connectors in parallel (from two
amps) into a simple RCA Y-cable to a pre-amplifier's power disconnect line
on a Pixel Loop.  Grounding this line on either amplifier will then remove
power from the antenna-mounted pre-amp whenever I transmit.  The power
coupler is a Clifton Labs Z1203B which is 100% compatible with the Pixel
Loop, but it operates silently at QSK speeds (unlike the original Pixel
power coupler which has a noisy relay).

Re: [Elecraft] Seeking input on KPA1500 station configurations

2017-06-13 Thread Ken G Kopp 
Hi Mike!

I used to use an AH-4.  Check the power handling capability of the unit.  I
think you'll find it's incapable of handling the KPA500, let alone the
KPA1500.

Re: [Elecraft] Seeking input on KPA1500 station configurations

2017-06-13 Thread Michael Zabel 
Hello group,

This is my first post here, but have been reading the mail for a while.
I currently do not have any Elecraft gear, but have built a K2, and owned
KX1 and KX3.

I am considering upgrading my station in the near future and am interested
in the control possibilities of the KPA 1500.

I currently use an AH-4 for remote tuning of a non resonant vertical dipole
that I use on the upper bands, and have on order a Stockcorner JC-4s
kilowatt remote tuner to replace the AH-4.

To the topic here, I am interested in the mention of a connection for the
AH-4 on the KPA 1500 and and what it's use would be given the mismatch of
the power ratings of the two devices?

Now on to the station setup I can imagine...

It would be useful in my station setup if the KPA 1500 could sense a
frequency change and initiate a 10-20 watt tune cycle with the JC-4s before
going back to online status. Ideally the KPA 1500 could do this without
communication with the exciter making that interface universal.

Alternately, with the K3(s), any tune initiation from the transceiver could
cause the KPA 1500 to initiate a tune cycle with the JC-4s with the KPA
1500 in bypass.

Or even more ideally, Elecraft comes out with a fully integrated remote
tuner to match the KPA 1500 for those of us who need the wider matching
range in our urban antenna restricted situations.

A wide range tuner in the shack would also work, but then you would only
want to do that with some very low loss coax like 7/8 Heliax.

Thanks for the opportunity to give input and for the example you set as a
company.

Re: [Elecraft] Seeking input on KPA1500 station configurations

2017-06-08 Thread Tom 

Hi,
Here's one..
Since the KPA1500 can be turned on remotely, why not have it generate the 
necessary signal on the K3 accessory connector to turn on the K3 as well?

Win4K3Suite can leverage this as well.

Subject: [Elecraft] Seeking input on KPA1500 station configurations

The KPA1500 has very flexible I/O, and plenty of space for adding new 
control features in firmware. I/O ports include Ethernet, USB, RS-232, K3 
Accessory connector (including Icom band voltages), AH-4, CI-V, keying input 
(PTT), ALC out, and remote power-on.


In order to prioritize our efforts towards the facilitation of remote 
control and interfacing, we’d like to hear from those considering how they 
might integrate a KPA1500 into their station. Please describe both 
third-party and home-built gear that you might be using. In what situations 
could the KPA1500 itself simplify setup or operation?


I can’t promise we’ll be able to respond to every question or suggestion, 
but we’ll keep all of your input for our internal discussions.

[Elecraft] Seeking input on KPA1500 station configurations

2017-06-08 Thread Wayne Burdick 
The KPA1500 has very flexible I/O, and plenty of space for adding new control 
features in firmware. I/O ports include Ethernet, USB, RS-232, K3 Accessory 
connector (including Icom band voltages), AH-4, CI-V, keying input (PTT), ALC 
out, and remote power-on.

In order to prioritize our efforts towards the facilitation of remote control 
and interfacing, we’d like to hear from those considering how they might 
integrate a KPA1500 into their station. Please describe both third-party and 
home-built gear that you might be using. In what situations could the KPA1500 
itself simplify setup or operation?
