I have noticed a lot of LP Panadaapters for sale. I am wondering why.
Do they work well? I have one but I haven't been able to get it working yet.

Perhaps elecraft is developing its own pandapter for the K3? This will
bring the K3 in front of IC-7800 and the SDRs

The LP-PAN Software Defined Panadapter works fantastic. I use the
K3/LP-PAN/PowerSDR combination and it far exceeds the panadapter display on
my IC-7800 in both weak signal sensitivity and real time display refresh
rate (not to mention the ability to mouse click on a displayed signal and
jump the K3 to it's frequency). I'm so spoiled that I seldom use the 7800
for CW operation anymore. Add to that CWSkimmer (running at the same time)
and I died and gone to heaven ;-)

Sooner or later Elecraft will develop a small board to put inside or maybe outside that taking the IF output will make it a standard NTSC format video out to be seen by a simple video monitor,wait and see,that will kill not only the old 7800 but also the new 7600 as well.
Don't forget our K3's are still a project in progress.

Many people buy the LP-PAN but get bogged down in it's complexity and end up
selling them. It's not "plug and play". You're dealing with:
1. K3 must have the KXV3 board, $99, installed.
2. BNC coax cable to LP-PAN.
3. LP-PAN $227 assembled.
4. Cables from LP-PAN to sound card.
5. Sound card (special). Not your average Soundblaster! I used the Creative
EMU 0202 external USB attached "audio interface". $100.
6. USB cable to PC.
7. Drivers installed for sound card.
8. PowerSDR-IF software from WU2X (download).
9. Configure, calibrate and choose from dozens of options and settings in
software.
"INSTRUCTIONS" for the LP-PAN are found at this link:
http://www.telepostinc.com/LP-PAN.html
"INSTRUCTIONS for PowerSDR-IF are found at this link:
http://www.wu2x.com/sdr.html
This is at best, confusing. Paragraph after paragraph of information that
has slowly evolved over months and months. Useful links, system
requirements, mods, betas, HRD, SDR-IQ.....It's a world of it's own!
I'm using LP-PAN here. Yes it took me quiet a while to make it all work. The
software locked up my PC. I had cable problems. I ended up changing PCs and
the one I have still isn't fast enough to actually use LP-PAN as a radio.
Too many pops and cracks but the scope is GREAT! I use it constantly.
Yea, you can set there and slowly twiddle the vfo knob across the band
searching for signals but with the scope you soon learn that you had been
tuning right past signals and didn't know it! All it takes is a brief pause
in transmission and you've missed him. Just a few days ago I landed on 6
meters and sat back and watched the scope. Soon a single blip appeared in
the cw portion for about 5 seconds. I clicked the mouse in the general area
and waited for about 30 seconds. Suddenly I heard CQ CQ CQ de W5VYH W5VYH K.
I snagged him. A distance of 625 miles. The only signal on 6 meters and CW
at that! It's the first 6 meter QSO I've had in 30 years. The band quickly
went dead and it was over.
Tell me....What are the odds of me working W5VYH if I had no bandscope?
ZERO, ZILCH....You could wear out 100 finger dimples and never accomplish
that!
Did I mention my antenna? A 200' doublet fed with ladder line....The tuner
in the K3 somehow found a match on 6 meters. BTW: That tuner is astounding.
It matches things that shouldn't be matched.

Yes I hope Elecraft comes out with a better solution than this cantankerous
hodgepodge of little black boxes, cables and weird software but until then
I'll keep on using it.

I purchased the LP-PAN because I came from several years of owning the Flex
5000A and it uses the same software. I had forgotten how to use knobs.

Only had one configuration problem and a phone call to Larry, fixed that.
It has worked perfectly since and I love using it. I am spoiled with the
scope, especially on 6 meters for the reasons mentioned. On the other
bands, tuning is so quick with a simple mouse click. It puts the frosting
on the K3.

Dave,

I purchased a LP-Pan and a E-MU 0202 a few weeks ago and had no problem
getting either of them working and interfacing DXBase. I wonder if you have
given Larry a call at Telepost?

The only minor problem I had was with the PowerSDR software. For reasons
only known to the "computer gods", it would not load correctly and when I
tried to run it, I would get three or four "fatal error" messages. I even
tried to un-install it and then re-install with no luck.

There was an easy fix that involved formating the hard drive and then
re-installing Windows XP (a "ritual" that should be done once a year
anyway). Fortunately, formattng the hard drive and re-installing XP is
pretty easy, but time consuming to download and install all the updates and
programs. With the fresh install, everything worked the first time.

I did have a couple of "procedural" questions, and a couple of quick calls
to Larry answered those.

It works really great and well worth the time and expense of installing it.

Linux users can install quisk-lppan-k3. It's a far simpler user interface
than the PowerSDR software. We're hoping to port it to Windows as well
some day. It can control the K3 directly, or work through fldigi, which
is a digimode program that itself runs on Windows, Mac, and Linux.

On that screen shot is that + and - about 20Khz? Shouldn't the system
be able to pull off 192Khz total width? It would also be really slick
if the waterfall was labeled with absolute values rather than relative
ones.

Honestly the only reason I haven't purchased an LP-PAN is because all
the computers at the house are running Linux. However I'm also VERY
hopeful that the Elecraft bandscope when it comes out doesn't require a
computer of any kind.

I'm not certain on my feelings of requiring that the device needs a VGA
monitor. I really hope that the thing is completely self contained and
even better if it was a box with an LCD of some sort and fits nice right
on top of the K3 and looks like it belongs there.

I guess time will only tell....

Brett,
Thanks for pointing it out. It was an old screen shot. I updated it to
a more recent one as the package does provide frequency control.

As for the bandwidth of the display, it's purely a function of the sound
card. On Linux, the EMU-0202 sound device supports 44.1 KHz unless it's
sent a USB command to change sample rate. I've worked with some other
Linux folks around the world to help fix this, and the results should be
coming out in new versions of the Linux "ALSA" sound system soon.
Unfortunately, it doesn't seem to get past 96 KHz. (The Mac driver for
the EMU-020 has this same limitation.)

You can use quisk and the LP-PAN with a less expensive sound card such
as the Griffin iMic or a 48KHz Creative USB product, all in the $40
range, and get a 48KHz bandwidth view coverage. If you're a CW or
digital mode operator, that's pretty much all you need, and it's about
half the cost of the EMU-0202.

I don't know what Elecraft's plans are, but I believe there's room for
both standalone display devices and shack computer integrated devices.
Quisk is an option for those of us who have the LP-PAN and use Linux in
the shack.

I can tell you that this, unfortunately, is impossible. The K3's display isn't bit-mapped
-- it has a fixed set of things that it can display.

I too admit that I've watched all of these LPPans go by at attractive prices because --
much as I want a panoramic display -- I am waiting for the Elecraft product. And I also
hope it will be a standalone device that does not require a computer.

You know what, I guess that Steve already knew that the K3's display wasn't
going to be able accommodate a landscape function ;-)

I too would like to express my desire for a build-in / stand alone unit for
the K3. One were I can hook up a monitor, a key board and maybe even a mouse
if I wanted too and do all the modes that are available. And also very
important, it should be more or less plug and play.

PC's and I don't go very well together and although the LP PAN stuff looks
and sounds very promising, it is way to complicated for me. I am glad that I
am able to update my K3 every once in a while. Kudo's to Elecraft for making
it that simple.

Also, for a "wireless" hobby, with LP PAN you sure as hell need a lot off
wires (pun intended ;-))

I think all of us find PCs a hassle. I worked with computers all my life but
there are still times when I want to attack the thing with a 4lb club
hammer.

Unfortunately for your requirement I think a PC would be the most cost
effective platform to do all that. I think the most we can hope for is
something that is just a panoramic display. The question in my mind is,
since for most people the benefit is being able to point and click to QSY,
how would that work using a separate display? Most people will still be
using a PC for logging etc. Having a separate screen for the display is not
an issue (in fact it would be a benefit to keep the main screen clear) but
having a separate screen that your mouse cannot click on doesn't seem like
an ergonomic ideal to me.

So I'm guessing that it will just be a passive display like the ones in the
Icom 756 series that you can look at but not click on.

Hi Vic,

It would be a pity if Elecraft's product could only be used to display the
K3's receiver IF, and could not be tuned to other frequencies and used to
display transmitter IMD products for example. Perhaps that would make the
product too expensive.

I haven't used a panaramic display but have wanted one for some time. I do
have a problem understanding how a stand alone display can possibly have the
capabilities of a PC based design as far as point and click to change the
radio to the frequency of the signal you are seeing.

I CAN see the usefulness of a second video display monitor on the PC to use
for some of the "extras" that would get covered up on you main screen when
you have it set the way you like.

I too am waiting for the Elecraft unit to see how it is implemented and it's
capabilities.

There are 'single board computers' available that would provide mouse, VGA, and RS232
support and which can be programmed to do whatever you want. They have simple operating
systems (sometimes forms of Linux) and are designed to be embedded in devices like this.
When you click on the display it would just send the appropriate rig-control command to
the K3.

A panoramic display unit could incorporate this plus a simple SDR to provide all these
functions.

If it did not include the display itself but could be connected to a VGA monitor, the
price could be kept reasonable. Monitors are cheap and used ones are often free. And the
owner could choose how big a display he wanted.

Click with what?
Plug a mouse/keyboard into the panadapter?
That's going to be some pretty fancy firmware programming and real
expensive.

I don't think there's any way for Elecraft to produce a standalone
panadapter that can compete with the LP-PAN/Sound card/Computer combo
either performance or price wise.

We'll see if they can prove me wrong.

I'm sure that Elecraft (or any other company) can design and produce just
about whatever is technologically feasible. However, the issue boils down
to at what cost, and then what market is out there to recover the costs.

Yes, it will be great if Elecraft does come out with a Panadapter "add on";
the last figure I heard was in the $700 to $800 dollar price range.
However, if one were to start "tacking on" all the features that every K3
owner feels is a "must have", the price would probably triple.

Now granted, if you add 2400 or so bucks to the price of the K3, it is
still considerable less than the piece of junk Icom sells for 12,000 bucks
(I guess 10,500 with all the discounts). Personally though, I don't think
the majority of K3 owner would want to fork over much more than 700 dollars
for a panadaptor. And this is especially true when you can achieve the
same results (and with a unit that will most likely do considerable more
than what is in the works at Elecraft) right now for under $300. A lot of
the "features" that seem to wanted are already functional or soon will be
with LP-Pan.

Yes, you do have to have a computer; but what ham out there does not own a
computer (especially amateurs that have found there "niche" in the hobby
were they want and need the capabilities of the K3)? If you can afford a
K3 (and the cost of a add on panadapter), I will "go out on a limb" and say
you can afford to purchase a computer.

You don't have to be a "computer geek" to install and configure LP-Pan,
LP-Bridge, and Power SDR. And if you run into problems, there seems to be
plenty of help on the LP reflector and my dealings with Larry at Telepost
leave me with the impression that he is more than willing to take the extra
step in helping you to get his product up and running.

I have had LP-Pan hooked up to my K3 for about a week and I am really
impressed with what it does. Went out and bought a second monitor for the
computer and I have PowerSDR displayed on it. Right now the display is 14"
wide and 7" in height; I can damn near read it without my glasses!

That is my "two cents worth".

Bah. There are tons of embedded PC boards that essentially offer the

I have (several) computers and I am a 'computer geek'. But I still want a standalone unit.

I want it to come on when the radio does and I don't want to mess around with all of the
issues surrounding a computer just to use it.

Point and click doesn't interest me ... I traded off a hamfest-won

I fully agree. Even more to the point, can anyone explain to me why it is at all important for a panadapter to be standalone, i.e., independent of a computer for either display or function?

1. Whether I am contesting or DXing or ragchewing, my computer is always connected to my K3 for logging and other functions (digital modes, memory buffers, etc). Why would I want to add another user interface in the form of a keyboard or mouse connected directly to the panadapter?

2. I guarantee I would be able to upgrade my computer for function or storage capacity more easily than I could the innards of a standalone panadapter. The more dedicated hardware in the panadapter, the more functionally stagnate it becomes.

3. External monitors with MUCH larger screens that would be practical for a standalone panadapter are cheap, as are video cards with dual monitor ports. What's the point of having a wide spectrum capability if the display scrunches it down to VGA dimensions?

4. Software that controlled the panadapter from the computer would almost certainly integrate more easily into other software such as logging or rig control programs, compared with firmware residing on the panadapter.


So ... why add cost and size in the form of panadapter hardware that can be done better and more cheaply with hardware that already exists? Are there that many K3 owners out there that use their rig like an FT-101?

Actually, you can buy a very competent refurbished computer (with warranty), a nice display, and LP-Pan for less than the price Elecraft has projected for the panadapter. Along with many others I am looking forward to the Elecraft panadapter with great anticipation, but if it doesn't offer performance and flexibility instead of redundant hardware I won't be very impressed.

Yes, you do have to have a computer; but what ham out there does not own a
computer (especially amateurs that have found there "niche" in the hobby
were they want and need the capabilities of the K3)? If you can afford a
K3 (and the cost of a add on panadapter), I will "go out on a limb" and say
you can afford to purchase a computer.

Dave,

I think what's turning many folks away is the combined complexity of cables,
temperamental drivers, high-end sound cards, and the need for a reasonably
competent PC (owing to PowerSDR software). That's a shame because much of
these problems are easy to overcome with the SDR-IQ unit. Only two cables
are used for connectivity and it's self-powered through the USB cable. Much
of the needed DSP processing power is assigned to the SDR-IQ rather than the
need to depend on PowerSDR or one of its variants that places a high CPU
demand on the PC when using a high-end sound card.

With the SDR-IQ, I've found my PC's CPU demand is minimal -- to the point
where I use it with an inexpensive Samsung netbook PC for point & click
tuning through SpectraVue software. The K3, netbook, SDR-IQ and two
cables -- and you're done. If the SDR-IQ is set up as only a panadpter
without the need for its internal demods, CPU demand is reduced further.

I'm sure Elecraft will make their panadapter as powerful as possible for the
price -- but it's pretty tough to beat the utility-to-price ratio of a $300
netbook + $495 SDR-IQ unit -- and use it for much more than just a
panadpter. If the small netbook monitor is not of sufficient size, just
plug-in a flatscreen LCD monitor of your choice. For me, I get a powerful
combination at home with large monitor and between the tiny SDR-IQ and
netbook, I can quickly take it portable with the K3 in a small Pelican case.

Anti point and clickers......Imagine replacing your computer mouse with two
knobs and a button. Remember Etch a Sketch? Once you get used to clicking on
signals with a mouse, going back to a knob would hurt. Sure, You'll get

Because some of us despise being forced to run Windows to use the
product. Some of us would also like the tools to continue working
well beyond when they are supported. If someone quits writing
software to support a particular tool it only takes the next version
of windows to feasibly turn that product into an expensive brick.

Personally I'd be ok with just a bandscope with a nice resolution and
very fast update rate without point and click functionality. Drop in
some more handy test type features (like Elecraft already has with the
AFV and what not)...

Honestly we already have a perfectly fine computer based solution and
it looks like its slowly getting better Linux support. Why would we
need another. I want my radio to perform like a radio so that I can
take it to the top of a hill and make it work sans computer. I've
already had a blast taking it up to a few mountain tops and making a
few RTTY contacts sans computer. Come on thats fun!

I'm still one of those guys that thinks an oscilloscope should have
knobs and buttons and no keyboard. I also think that an oscilloscope
shouldn't take several minutes to boot up! Some things just aren't
made better by adding a computer.

After reconsidering I came to the conclusion that I just want to be able to
see a portion of the band I'm on.
Sure, point and click would be nice but if I really want that, I'll go with
the all ready existing panadapter or something like Flexradio.

Yes, I have a PC in my shack and it is used for logging and updating the K3
and surfing on the www, that's it. I don't want it to do anything else. I
just don't get along with those darn things.
When I was young all my friends were starting to get familiar with PC's. My
parents didn't buy one because they thought it was just a hype and it would
blow over. Boy were they wrong. By the time we finally got one all my
friends could do magic with these things (at least in my eyes they could)
and all I could do with it was turning it on and off. I lost interest before
I even got started.
When I got older I got confronted with fact that I couldn't get around
them so I learned how to use then but I never could really enjoy it. I still
don't for that matter.

I'm probably missing out on a whole bunch of stuff but I guess I don't know
exactly what it is that I'm missing and therefore I don't Miss it. (that
sentence can't be wright but I think you know what I mean)

I will now go to "start" and turn off my PC (I know, that's Windows and not
the PC itself) and turn on the K3 to make some Q's.

I suspect you expect too much from a $300 netbook thingy.

But isn't it amazing that the price of the computer (even a not-
netbook) might be less than the price of the RF head. How is that
possible -- with all of those 12AU7 dual triode flip-flops in the
computer :-)

Honestly I'm perfectly fine with a computer solution but I want the
same amount of power and flexibility no matter if I'm sitting in front
of Windows or Linux or even Mac for that matter! I give high praise
to Elecraft for keeping software update utilities for all 3 OSes and
they are all kept up to date!

However all this being said there is already a computer solution which
is no where near as powerful in Linux but its coming along... Why do
we need yet another of the same thing? For me an embedded solution
would be where its at. I'd like to see something with a PXA310 or
similar processor that was essentially a PDA with a specialized wider
shorter display. Implementing it as a touchscreen would be nice but a
lot of the hams I've known would be way to ham fisted to be able to
operate it and so they'd just complain. I see good value in adding a
good fast updating display with decent resolution. Oh and I'm all for
small too! My eyes still work good!

How about a variable rate tuning knob with a built in push switch. I am
thinking of the tuning system on the old (1970s) Cubic/Swan Astro 150.
This was a variable rate spring loaded rotary control that speeds up the
tuning rate as it is turned further clockwise or counter-clockwise from
the detented center position. It would suit those that do not like extra
cables and clutter on their desks.

I'd like to have it for field day and sometimes having that sitting there is
easier to find CQers than constantly actively scanning... Helps ya keep the
fire going if you don't have to be scanning all the time... The scan
feature works a trick but a panadapter would be nicer. Also a panadapter
can turn out to be a nice poor man's SpecAn in a pinch.

Vic,

Your point is well taken; but in the end what percentage of amatuers that
own a K3 do not have it hooked up to a computer and a logging program; and I
bet that most amateurs leave their computer on 24/7 and connected to a DX
Cluster.

Like Dave (AB7E) who posted a comment, I am also part of the aforementioned
group, my computer is on all the time; thus PowerSDR and LP Bridge are also
on all the time. When I turn on the K3, LP-Pan (which is powered by the Aux
12V out on the K3) turns on, and bingo, signals appear on the PowerSDR
screen. If for some reason (like going on vacation) I turn off my
computer, when I turn it back on, I just start LP Bridge and that auto
starts both DXBase and PowerSDR. Basically one click and one button push
on the K3 and I am in business.

Actually, I have to admit that it is slightly more complicated than that;
after I turn on the K3, I have to push the on/off switch on the Green Heron
Eng rotor box to on. The Green Heron is plugged into a AC switch that all
the other assorted and sundry accessories are plugged into, and turning it
on, powers up the rest of the station.

So, I guess that I have not figured out what all the other "issues" might be
in having a panadapter run by your computer?? Actually I spend more time
in the summer connecting and disconnecting the coax and rotor cables because
of the thundrestorms than I do "turning on" the K3 and Green Heron Rotor
box.

In any case, I am sure that your wish for a stand alone unit will come true.
The only question is what features and at what cost will the Elecraft unit
have. One thing I am sure of is the display will not be of the 17" to 22"
variity.

One other interesting point that should be brought upis that CW Skimmer
works very well with LP-Bridge.. Though I have not installed it yet, I
have been told that CW Skimmer is the "cats meow" to the CW contester or
DXer; and to them, it is what Viagra is to the "old timers"! It works
great and allows them to do things they had never done before!

It's quite likely that the cheapest way for Elecraft to implement such a
product would result in its running Windows, albeit XP embedded, on
flash. The next alternative would be Linux.

Just a gentle suggestion from a non-K3 guy.

A while back it was brought up that we'd place the model # of the rig being
discussed in the subject line of our posts, when applicable.

Like, "K3" when we were talking about that rig, or K1, etc. Threads of
general interest would not have any specific identifier.

The purpose was so that people not interested in the thread about a given
model # could filter it out.

I fully understand that another way to avoid this problem is to buy ALL of
the Elecraft rigs so we'd have an interest in everything, but some of us
haven't had taken that route (Yet :) ). So I'd respectfully request that
we go back to that protocol as some have continued.

Thanks

"Lowly" K2, Tom??

For me the jury's still out: my nice analog K2 or the very flexible and
feature-rich digital K3.

I'll probably never decide, just as I won't bother to decide whether 80 or
40 meters is a better band. They're just different, that's all. They do
different things better.

As for your suggestion, good point. From the e-mail reflector guidelines on
the Elecraft web site:

4b. When emailing about a specific rig or option, please add the rig/option
name(s) to the first part of your email subject line. (K1, K2, K3,
KX1 etc.) This will be a huge help for those experiencing email overload and
will allow automatic filtering based on subject line.

Examples:

"Subject: [K3] Filter Options"
"Subject: [KX1] How to use ped portable?"
"Subject: [XG2] Wow! Its a big help.

I certainly don't do that. Our electricity bill is high enough as it is, and
besides, leaving stuff switched on when it isn't being used is not a very
responsible use of non-renewable resources.

I'd be happier with a computer-based solution if the software ONLY gave you
the panoramic display. I want a standalone display that I can use alongside
the software of my choice but although I certainly understand the reasoning
of those who want one that will work without a PC I personally don't mind if
it is a standalone application. I can always buy a second monitor to display
it on if I want to. What I don't want or need is a whole screenful of
PowerSDR which was designed to be the front end to a fully computer
controlled radio not a "simple" panadapter.

I would find a "hybrid" solution more useful, ie. stand-alone or capable
of interfacing w/ a PC. The current problem I run into now is that
there is no "practical" way to run two LP-PANs (specifically PowerSDR)
on one PC, one for each of two K3s. I've tested doing so w/ one
instance of PowerSDR in a VMware container, but additional bandwidth
limitations (virtual sound device), delays, et.al. are less than
optimum. With two stand-alone units, there wouldn't be a particular
PC-related limitation, but then "point-and-click" may be lost. Though,
as I understand it, there were plans to use a "tuning" knob on the front
panel with push capability to jump to K3 to the freq. were the on-screen
marker is located.

The Elecraft panadapter could take a couple directions as far as PC
integration. 1) Provide I/Q outputs to interface w/ the PC's soundcard,
or 2) Have a built-in USB sound device (ie. similar to some Microham
devices). The latter would certainly increase costs, but would
eliminate the need to go out and purchase a high-end card; maybe include
it as an add-on option in the same style as everything else in the K3 realm.

Anyways, it will be interesting to see the product when it arrives.

Here is one way to pull off what you want... Use 2 PC's and 2 LP-PAN's
with your 2 K3's and then user Synergy to tie the two PCs together. I
use this at work. I have two monitors and two PC's (one running linux
and the other running windows) and I'm able to share one keyboard and
mouse between the two computers. I can move my mouse from one monitor
to the other and which ever computer has the mouse cursor on the screen
is the one that gets the keyboard focus. Its kinda complicated to
explain but if you see it in action it works like a single computer with
two displays except for the fact that there is a different computer
running each monitor. They can both be windows boxes if you want to do
it that way and you would for running 2 LP Pan's. You're of course
going to need two sound cards too...

Actually, there a number of folks running multiple instances of
LP-PAN/PowerSDR, both with two K3s and with a K3 with KRX3. It is not
terribly difficult if you are computer savvy, and requires a newish PC (duo
or quad core), but there is nothing in either program which prevents
multiple instances and nothing that prevents multiple sound cards. LP-Bridge
even provides the ability to launch two instances of PowerSDR at start-up.
Check the archives of the LP-PAN User Group for some feedback on this
process.

There are some new developments coming with updated versions of PowerSDR for
panadapter use, and a new LP-Bridge. Things go a little slower in summer
with vacations, family commitments, etc., but development is definitely
continuing on several fronts.
