LP PAN FOR SALE

[Tom McCulloch]

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

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.

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.

Yea I figured this was possible but I was trying to help solve the issue
in the manner the person was looking to.  And using synergy would allow
one to get the job done with two lesser machines.  The worlds greatest
multi tasker is another computer... ;)

Thanks much Larry...
