If you expect 100 KHz (more than 22 KHz) with CW Skimmer you will need
to split the receive antenna loop and feed a true SDR (e.g., SDR I/Q, 
Perseus, QSR1, etc or equivalent) tuned to the bottom of the active
band.  See the CW skimmer documentation - any configuration that feeds
skimmer from the IF and tracks the IF offset is limited to 22 KHz (the
operating frequency +/- 11 KHz).
[pjd] 
[pjd] Yes, that was my understanding (after having bought the LP-PAN, of
course). Is there such a thing as an easily affordable "True SDR"? I priced
out the Perseus and it's far out of my ballpark, and the SDR I/Q is no
longer being made.

 >>The "direct" receiver configuration does not require/use microHAM
Router.  Other software is used to link logging software and skimmer.

[pjd] I'm not sure what you mean by that. Can you please elaborate a little?
I've tried the LP-Bridge and a NaP3 and that just complicates things far
worse. I'm after "dirt simple" and "easy to configure." The last thing I
want is for something to get messed up 10 minutes into CQWW-CW and I'm out
of the game until I can troubleshoot it. I'm looking for a one-box solution
if such a thing exists, set it (document it) and forget it, and it just
works whenever N1MM+ is running, or when I'm using DX Labs.

I am able to make it work Skimmer work with DX Labs Commander, but, again,
subject to the IF limitations that I only realized existed after having
bought it.

My eyes glaze over at the thought of Skimmer, but I heartily agree with Don 
about LP-Bridge.  I use it with my K3s and run my logging program (DXBase), 
SpectraVue (runs SDR-IQ as bandscope), MMTTY, FLDIGI, N1MM, etc.  LP-Bridge
will 
also start all of these programs automatically when executed.

[pjd] I tried LP-Bridge but it was conflicting with something else in the
system, and I'm guessing it was Router. It would just never open any defined
ports, or if it did, it would do it once but never again afterwards until I
shut the system down and restarted. Too much hassle. I like the KISS
principle and all that extra overhead was making my head spin.

[pjd] There are two big advantages with Skimmer for me: 1), in contests, I
can see what my antenna can hear, not what a massive cluster node can hear.
I'm behind a mountain to Europe and only have a single 70' tower and a
tribander, and even with the K3S, I can only hear about 50-60% of the spots
on the local node. I can't run in CW, so while I'm S, I can keep my
"rate" going if I can definitively see who's where, and not pausing to
listen on frequencies that are empty, or missing unspotted calls. 2), in
DXing, I want to see the pileup and know exactly where to drop my call in
after the last guy is giving his report. I don't enjoy snarling bedlam and
the sooner I can get in, work the guy and get out again, the happier I am.

[pjd] They're younger computer-oriented guys, and having the ability to
monitor multiple bands at the same time (and for one of the, doing SO2R with
one radio). I gotta admit, this intrigues the hell out of me. Plus it's all
IP controlled, so no need for a rat's nest behind the radio, and no need for
boxes like the MicroHam; everything is controlled via software and IP. Plus
according to them, it's far easier to remote than the K3, but I'm not
finding any problem with Remotehams to be honest.

Still all in all, I'm extremely intrigued by having one box to do everything
in the station, especially multiple panadapters built in, SO2R in a box, the
ability to monitor and skim several bands at once, keep on RX on 6m JT-65 at
all times regardless of what else the radio is doing, etc.  I really fell in
love with my K3S when I bought it last year and I'm slowly learning to use
it, but I have to wonder if I made the right choice when I read their posts
about having a pure SDR solution, the ease of setup, etc. I am too old,
infirm and poor to travel so I don't need a DXpeditioner's Dream, but rather
a DXer/Contester's ultimate weapon. 

I will probably keep the K3S, but I'm still not convinced it's the right
tool for what I need to do and my style of operating. I just don't know
enough about modern radios to make an informed decision to be honest.

I echo what you say, David. I have K2/100 #380 
started in July 1999, with all the subsequent

It's still a very solid radio I use in my second

everything in it (excepting part of the KDSP2

Subject: Re: [Elecraft] Skimmer and the K3S

Pete,

I think you are mixing too many things together, and they are not
necessarily related.
Let me try to 'unravel the ball of twine' for you.

The birdies/mirror images you encountered are not the fault of LP-Pan, but
instead related to either your soundcard cables or the capability of the
Panadapter display software that you were using.

[pjd] I have tried four different sound cards on a very powerful PC (i7/32GB
RAM/SSD that has tons of processor, drive and RAM headroom, with virtually
nothing running), the birdies are identical with all the different sound
cards. I stuck with the Xonar U5. I've been over the level settings a
hundred times and that's not the issue. I believe I read somewhere that an
xtal oscillator inside the LP is the cause. There is nothing I can do to fix
it.


 >>Since you now have the P3 and are apparently happy with it for the
Panadapter display,  I suggest you continue to use it.
 >>BUT,  you cannot display Skimmer on the P3.
[pjd] I never did. I use the IF OUT from the K3S backplane to the IF IN on
the P3, then use the IF OUT from the P3 (setting the switch on the back to
open that port up) to feed into the LP-PAN.

[pjd] >>Connect the K3 IF output to both the P and the LP-Pan (use a BNC T
adapter).
[pjd] See above.

Connect the LP-Pan I/Q outputs to your computer soundcard and load 
Skimmer on your computer.Configure CW Skimmer to use that soundcard 
and it will display whatever is within it's "hearing range".  The document
at http://www.dxatlas.com/CwSkimmer/Files/Skimmerintro.pdf may be helpful
with your setup.

[pjd] Yes, this was all done when I bought the LP-PAN and Skimmer. It IS
working as best it can, but it cannot do what I need it to do, and that's
why I'm posting here--unless I've completely misunderstood the LP-PAN
limitations. That device seems to only allow me to see something like 22 kHz
on either side of my tuned frequency. If I'm working at 14.022, that's
great. I can see 14.000 to 12.044. If I'm S at 14.095 I'm kinda hosed.

I reiterate, I need to be able to see then entire CW sub-band (or as much as
possible), from 14.000 to 14.100 at least. I'd be good with a 96 kHz spread
(14.0-14.096), INDEPENDENT of where my 2nd VFO is tuned. I do not believe
LP-PAN can achieve this desired goal, but again, I could be mistaken. 

 >>Note carefully, you do not have to run NaP3 or other panadapter
applications - CW Skimmer is independent of those.
[pjd] That's good, because I don't' want to run any of those. I just want
the decoded calls to show up on my bandmap.

If you need to run other PC applications (loggers and other rig control
applications) that each want to use the COM port connection to your K3 (in
addition to CW Skimmer) - only one application can talk with the K3 at the
same time.  Enter LP-Bridge or Com-O-Com which create virtual ports on your
PC.  IMHO LP-Bridge is a good choice for use with the K3, but all your
applications that want to talk with the K3 will talk instead to their own
LP-Bridge virtual ports - only LP-Bridge connects directly to the K3.

[pjd] LP- Bridge will not work on my system, period. I've tried for months
to make it play and it just won't. It's also probably not necessary for what
I want to do. I get failure after failure, and I'm 99% sure it's conflicting
with MicroHam Router (software I desperately wish I could dispense with
forever, but I can't achieve half the functionality of my station without a
MicroKeyer-II).

That's pretty interesting if you actually have the filters defined in the
K3/K3s as 1.8 kHz. Because what will happen when you set front panel WIDTH
control (the DSP width) to 2.1 is that the K3 will engage filters defined
as 2.1, or the next wider set of filters and will NOT be using the 1.8's.

However if you deliberately define those 1.8 filters as 2.1 in the filter
setup, then you will basically be hearing the selectivity of the two 1.8
roofers when your WIDTH control is at 2.1.

I have my 8 pole 1.8 roofers defined as 1.8. Can't stand them for casual
SSB & yak fests, but they are cat's meow for SSB contests. I have to ride
the shift control all the time for intelligibility, but that's better than
not being able to understand because the crud is terrible above or below.
If crud is terrible above AND below, some part of it is going to be IN the
bandpass and I have to give up and move.

John W2ID:

You do realize that these are roofing filters and that operating bw is set
by the DSP?  Of course if you are operating in a dense high signal
environment (lots of QRM on adjacent freq) then having a roofing filter that
matches your operating bw is helpful.

I have both main and sub Rx but only use a duplicate of my SSB filter
(2.8-KHz 8-pole) in my sub receiver.  I initially bought a 13-KHz filter for
the sub-Rx not realizing it was not going to be used for diversity on FM so
I sold it soon after purchase.  I have 13-KHz because I use my K3/10 with
VHF/UHF transverters operating FM.  I do no AM but can use that filter for
AM.  I also bought a 400-Hz filter thinking it would help receiving CW, and
it does (almost too good). 
But having more noise suppression in the narrower bw does help weak CW copy
(since I only use CW for eme).

Adding more filters to the sub-Rx is not as difficult as to the main-Rx.
The sub-Rx has to be removed to add/remove or change filters in the main-Rx.
So try to get the arrangement in the main-Rx before installing the sub-Rx.

But for casual CW listening I usually dial DSP bw to 1.0 KHz for easier
listening.

I only run diversity mode for running 2m eme using digital mode of JT65b
using MAP65 sw which enables dual receive of two receivers.

But like the KX2,  both K3 and K3s do not provide IQ interface, so I tap off
the 1st IF of both receivers to go to two SDR which are phase-locked in
frequency so that diversity info is preserved at the soundcard.  Because I
tap off the 8.2 MHz IF's the signal does not go thru the roofing filters or
the DSP in the K3.  The K3 merely acts as a tunable down converter from
28-MHz which what my transverters input at.

I know this has little to offer in your decision on filters to install.  I
kept it simple (one SSB filter in my  sub-Rx).

Thanks Alan,

Yes, by all means ignore my suggestion about using the T adapter and

Sorry for my mental lapse - I should have been thinking better,

afternoon, and knew perfectly well that the P3 has an IF out. That is a 
replication of the IF IN.

No adapter is required.  The P3 has an internal 3 dB splitter and an 
IF OUT connector that can be connected to LP-PAN.  Just make sure the 
rear-panel switch is in the "ON" (up) position.

Re: [Elecraft] Skimmer and the K3S

[Joe Subich, W4TV]

If you expect 100 KHz (more than 22 KHz) with CW Skimmer you will need
to split the receive antenna loop and feed a true SDR (e.g., SDR I/Q, 
Perseus, QSR1, etc or equivalent) tuned to the bottom of the active

band.  See the CW skimmer documentation - any configuration that feeds
skimmer from the IF and tracks the IF offset is limited to 22 KHz (the
operating frequency +/- 11 KHz).

This is a design choice made by the developer of CW Skimmer.  If you
have questions, contact him.

The "direct" receiver configuration does not require/use microHAM
Router.  Other software is used to link logging software and skimmer.

Hello all,
With the vast majority of my friends having gone the Flex route rather than

everybody who's running it. I just can't figure out how to make it work
acceptably well with the K3S/P3 combination I have here.

I went the LP-PAN route and the birdies/mirror images make that device
wholly unsuitable for me, so I'm back to square one. I don't want to spend
another small fortune on interface boxes, but something better than LP-PAN
is clearly the answer. I just don't know what it is, what to do once I buy
it, or anything else. The big limitation I have is whatever devices that I
will need to buy will also have to play well with MicroHam Router software,
and in the past that has left my head spinning. This stuff is SO far beyond
my understanding I feel as if I've been thrown into the deep end of the pool
without knowing how to swim.

Working backwards, let's say the required end result is to have the CW
portion of whichever band I'm on skimmed and calls displayed on my bandmap
in either N1MM+ or DX Labs' Commander. Not 22kHz worth of calls relative to
my operating frequency, but everything, from .000 to .100 and maybe beyond.
If I'm running in CQWW or ARRL-CW, I'm less impressed with what the cluster
is showing me and would rather rely more heavily on what my own antenna is
picking up.

I have only two antenna feeds on the property: Whatever's selected on the
tower or a K9AY loop connected to the RX-in line on the back of the K3S. I
don't' have a separate antenna to feed another receiver so I guess the idea
is to take signal off the IF from the P3 out, yes? Like I said, I'm really
very old-school and I need help getting up to speed with all this stuff. I
migrated from a Mark V last year and the learning curve on the K3S is still
as steep as Mt. Everest for me. Any help greatly appreciated,
please'n'thanks!

Re: [Elecraft] Skimmer and the K3S

[Alan Bloom]

Excellent explanation Don.  Just one thing:

> Connect the K3 IF output to both the P and the LP-Pan (use a BNC T
> adapter).

No adapter is required.  The P3 has an internal 3 dB splitter and an IF 
OUT connector that can be connected to LP-PAN.  Just make sure the 
rear-panel switch is in the "ON" (up) position.

Let me try to 'unravel the ball of twine' for you.

The birdies/mirror images you encountered are not the fault of LP-Pan,

the Panadapter display software that you were using.

Since you now have the P3 and are apparently happy with it for the
Panadapter display,  I suggest you continue to use it.

BUT,  you cannot display Skimmer on the P3.

So 'what to do'? - I would suggest that you use the LP-Pan hardware.
Connect the K3 IF output to both the P and the LP-Pan (use a BNC T
adapter).

Connect the LP-Pan I/Q outputs to your computer soundcard and load
Skimmer on your computer.Configure CW Skimmer to use that soundcard
and it will display whatever is within it's "hearing range".  The
document at http://www.dxatlas.com/CwSkimmer/Files/Skimmerintro.pdf may
be helpful with your setup.
Note carefully, you do not have to run NaP3 or other panadapter
applications - CW Skimmer is independent of those.

If you need to run other PC applications (loggers and other rig control
applications) that each want to use the COM port connection to your K3
(in addition to CW Skimmer) - only one application can talk with the K3
at the same time.  Enter LP-Bridge or Com-O-Com which create virtual
ports on your PC.  IMHO LP-Bridge is a good choice for use with the K3,
but all your applications that want to talk with the K3 will talk
instead to their own LP-Bridge virtual ports - only LP-Bridge connects
directly to the K3.

Hopefully that helps.

Re: [Elecraft] Skimmer and the K3S

[Wes Stewart]

My eyes glaze over at the thought of Skimmer, but I heartily agree with Don 
about LP-Bridge.  I use it with my K3s and run my logging program (DXBase), 
SpectraVue (runs SDR-IQ as bandscope), MMTTY, FLDIGI, N1MM, etc.  LP-Bridge will 
also start all of these programs automatically when executed.

everybody who's running it. I just can't figure out how to make it work
acceptably well with the K3S/P3 combination I have here.

I went the LP-PAN route and the birdies/mirror images make that device
wholly unsuitable for me, so I'm back to square one. I don't want to spend
another small fortune on interface boxes, but something better than LP-PAN
is clearly the answer. I just don't know what it is, what to do once I buy
it, or anything else.

That's pretty interesting if you actually have the filters defined in the
K3/K3s as 1.8 kHz. Because what will happen when you set front panel WIDTH
control (the DSP width) to 2.1 is that the K3 will engage filters defined
as 2.1, or the next wider set of filters and will NOT be using the 1.8's.

However if you deliberately define those 1.8 filters as 2.1 in the filter
setup, then you will basically be hearing the selectivity of the two 1.8
roofers when your WIDTH control is at 2.1.

I have my 8 pole 1.8 roofers defined as 1.8. Can't stand them for casual
SSB & yak fests, but they are cat's meow for SSB contests. I have to ride
the shift control all the time for intelligibility, but that's better than
not being able to understand because the crud is terrible above or below.
If crud is terrible above AND below, some part of it is going to be IN the
bandpass and I have to give up and move.

Re: [Elecraft] Recommended filters for Diversity Receive?

I rarely use bw above 1.8 on ssb with adjustment on Hi/Lo cut set accordingly. 
Audio on Rx is very good and also using Yamaha CM500 headset.
To "my" ears, this is "nice" to listen to and I have been using these settings 
for years on my K3.

John W2ID:

You do realize that these are roofing filters and that operating bw is set
by the DSP?  Of course if you are operating in a dense high signal
environment (lots of QRM on adjacent freq) then having a roofing filter that
matches your operating bw is helpful.

I have both main and sub Rx but only use a duplicate of my SSB filter
(2.8-KHz 8-pole) in my sub receiver.  I initially bought a 13-KHz filter for
the sub-Rx not realizing it was not going to be used for diversity on FM so
I sold it soon after purchase.  I have 13-KHz because I use my K3/10 with
VHF/UHF transverters operating FM.  I do no AM but can use that filter for
AM.  I also bought a 400-Hz filter thinking it would help receiving CW, and
it does (almost too good). 
But having more noise suppression in the narrower bw does help weak CW copy
(since I only use CW for eme).

Adding more filters to the sub-Rx is not as difficult as to the main-Rx.
The sub-Rx has to be removed to add/remove or change filters in the main-Rx.
So try to get the arrangement in the main-Rx before installing the sub-Rx.

But for casual CW listening I usually dial DSP bw to 1.0 KHz for easier
listening.

I only run diversity mode for running 2m eme using digital mode of JT65b
using MAP65 sw which enables dual receive of two receivers.

But like the KX2,  both K3 and K3s do not provide IQ interface, so I tap off
the 1st IF of both receivers to go to two SDR which are phase-locked in
frequency so that diversity info is preserved at the soundcard.  Because I
tap off the 8.2 MHz IF's the signal does not go thru the roofing filters or
the DSP in the K3.  The K3 merely acts as a tunable down converter from
28-MHz which what my transverters input at.

I know this has little to offer in your decision on filters to install.  I
kept it simple (one SSB filter in my  sub-Rx).

Hi Tim, 

I just verified the bug on my unit here.  I'll put it on the list.  In the
meantime you can set TxtAuto so it is enabled.  This will automatically turn

Re: [Elecraft] SSB Contesting filtering out contesters

[Jim Rhodes]

And don't forget the AGC and RF gain settings. Often those nasty signals
can be minimized by proper use of the two. Modern receivers tend to have
better dynamic range and sometimes those nasty, wide signals can be reduced
in strength so that the filters can do a better job.

Re: [Elecraft] SSB Contesting filtering out contesters

[Ron D'Eau Claire]

David, it's called QRM and has been with us since the first spark
transmitters were on the air. 

On CW how does the frequency of the interfering stations compare with the
ones you are trying to hear? I'm referring to the audio frequency of the CW
signal you hear in the speaker or headphones compared to the desired signal.
If they are very nearly the same, it's because the interfering signal is on
the same frequency as the one you want to hear. 

Since Ham bands are not "channelized", any station can operate on any
frequency within the band. Interfering stations can end up on your frequency
in several ways. It might just be a careless operator who didn't listen
first or one who didn't care if other signals were present. Unfortunately,
this happens a lot in contests. Just as likely, it may be because of
propagation. It's common for other stations in different locations to not be
able to hear the signals you do. That's why good Ham protocol is to send
QRL? (is the frequency in use?) before starting a call. In that case you
could send an "R" indicating the frequency is in use even though the other
station could not hear. But, again, that is often overlooked in Contesting.
Also, it's possible for the interfering station to not be able to hear
either of you due to high noise levels, poor receiver, etc. 

Another possibility that is becoming very rare with modern equipment is that
the interfering signal might be a spurious (unintended) signal on a
frequency far from the other station's main signal. 

Yes, directional antennas help, but on HF especially many Hams must make do
with whatever antenna they can put up in their yard or garden.

Re: [Elecraft] SSB Contesting filtering out contesters

[n9tf]

David, 
Jim is spot on about wide dirty signals getting into your passband. The best 
you can do is play with the band width and shift to find a combination that 
limits the interference and makes the signal you are trying to copy, more 
copyable. For SSB contesting I will use the 2.1khz filter with a bit of DSP and 
also some shift to knock down the interfering station. I will say, the K3/S is 
far superior to the 756ProIII I had prior in this regard, from sharp filtering 
and AGC pumping. I can usually knock out a strong wide signal well into the 
passband I am listening, so that I can copy the weaker station. 
  
I am amazed though how close these days SSB contesters "overlap" intentionally 
into someone else's frequency, sharing half of the 2.7khz band width! That's 
one reason I prefer and enjoy CW and RTTY contests over SSB contests. Much more 
pleasing on the ears and temper!

Re: [Elecraft] Recommended filters for Diversity Receive?

[Edward R Cole]

John W2ID:

You do realize that these are roofing filters and that operating bw 
is set by the DSP?  Of course if you are operating in a dense high 
signal environment (lots of QRM on adjacent freq) then having a 
roofing filter that matches your operating bw is helpful.


I have both main and sub Rx but only use a duplicate of my SSB filter 
(2.8-KHz 8-pole) in my sub receiver.  I initially bought a 13-KHz 
filter for the sub-Rx not realizing it was not going to be used for 
diversity on FM so I sold it soon after purchase.  I have 13-KHz 
because I use my K3/10 with VHF/UHF transverters operating FM.  I do 
no AM but can use that filter for AM.  I also bought a 400-Hz filter 
thinking it would help receiving CW, and it does (almost too good). 
But having more noise suppression in the narrower bw does help weak 
CW copy (since I only use CW for eme).


Adding more filters to the sub-Rx is not as difficult as to the 
main-Rx.  The sub-Rx has to be removed to add/remove or change 
filters in the main-Rx.  So try to get the arrangement in the main-Rx 
before installing the sub-Rx.


But for casual CW listening I usually dial DSP bw to 1.0 KHz for 
easier listening.


I only run diversity mode for running 2m eme using digital mode of 
JT65b using MAP65 sw which enables dual receive of two receivers.


But like the KX2,  both K3 and K3s do not provide IQ interface, so I 
tap off the 1st IF of both receivers to go to two SDR which are 
phase-locked in frequency so that diversity info is preserved at the 
soundcard.  Because I tap off the 8.2 MHz IF's the signal does not go 
thru the roofing filters or the DSP in the K3.  The K3 merely acts as 
a tunable down converter from 28-MHz which what my transverters input at.


I know this has little to offer in your decision on filters to 
install.  I kept it simple (one SSB filter in my  sub-Rx).

Re: [Elecraft] (Update) PX3 text not working

[Joe Stone (KF5WBO)]

Same here.  This is an "undocumented feature" (i.e., firmware bug).  Please
E-mail Paul Saffren (psaffren at elecraft dot com).

You can enable and disable text using the "LABELS" (hold) switch.  This
won't require a power-cycle to take effect.  This is probably easier than
using the menu.

Nothing new here -- NO receiver can "filter out" interference that is 
inside its passband. If a station is transmitting trash (splatter) ON 
YOUR FREQUENCY, there is NO solution other than him fixing his dirty 
station. This splatter (and key clicks) can be VERY clearly seen on a 
properly adjusted P3 as horizontal lines in the waterfall from a dirty 
signal on audio peaks.

[Elecraft] (Update) PX3 text not working

[Tim Cook]

Making some progress, found that after enabling text on the PX3 I have to turn 
the PX3 off then on and then the decoded text will show up on the display.  If 
I turn off text and on via the menu it stops decoding and won't start again 
until I cycle the power on the PX3.

Any thoughts?

Re: [Elecraft] SSB Contesting filtering out contesters

[Nate Bargmann]

It is a way of life.  That said, I have found that for stations below my
frequency on LSB or above it on USB that I can advanced the Hi Cut
control quite a ways while maintaining intelligibility of the received
signal.  The converse, stations above on LSB or below on USB cause me
more problems as intelligibility deteriorates rapidly as the Lo Cut
control is advanced.  This is with a K3 with a 2.1 kHz filter installed.

Still, the K3 is the absolute best in this regard of a number of radios
I've used over the years.  This is just due to the characteristics of
SSB and the way we use it in amateur radio.

I agree, Bob.  Controlling marker A (or marker B) and QSY'ing the rig VFO to
the marker frequency is a primary use case for any remote control panel.

I want to be clear ... porting the #MAA and #MBA remote-control commands to
the P3 will enable control of the P3 markers using the PigKnob.  I can't
speak to what's involved in controlling the P3 markers using the K-Pod.

[Elecraft] Diversity RX question

[Peter W2IRT]

So, I'm wondering if I will be able to use Diversity RX on my K3S given my
antenna situation. At the moment I have ANT-1 connected to my remote antenna
switch at the tower, which selects 10-160m. ANT-2 is a 6m Yagi on a separate
tower, and a K9AY loop is connected via BNC to the RX antenna port on the
K3S. Those are all the antennas I possess, and my understanding is that I
need another dedicated antenna for diversity. Is there any way I can use
what I have to get diversity and still retain use of the RX antenna port
feature for the lowbands? If not, what are most people using for diversity?
Is this something that's used on all bands or is it a predominantly lowband
feature (which is where I need the most CW RX help given my very noisy QTH)?

Thanks in advance.

[Elecraft] Skimmer and the K3S

[Peter W2IRT]

Hello all,
With the vast majority of my friends having gone the Flex route rather than
the K3, I'm finding I'm at a rather huge disadvantage in terms of CW
operation, and that's Skimmer, which is an absolute game-changer for
everybody who's running it. I just can't figure out how to make it work
acceptably well with the K3S/P3 combination I have here.

I went the LP-PAN route and the birdies/mirror images make that device
wholly unsuitable for me, so I'm back to square one. I don't want to spend
another small fortune on interface boxes, but something better than LP-PAN
is clearly the answer. I just don't know what it is, what to do once I buy
it, or anything else. The big limitation I have is whatever devices that I
will need to buy will also have to play well with MicroHam Router software,
and in the past that has left my head spinning. This stuff is SO far beyond
my understanding I feel as if I've been thrown into the deep end of the pool
without knowing how to swim.

Working backwards, let's say the required end result is to have the CW
portion of whichever band I'm on skimmed and calls displayed on my bandmap
in either N1MM+ or DX Labs' Commander. Not 22kHz worth of calls relative to
my operating frequency, but everything, from .000 to .100 and maybe beyond.
If I'm running in CQWW or ARRL-CW, I'm less impressed with what the cluster
is showing me and would rather rely more heavily on what my own antenna is
picking up.

I have only two antenna feeds on the property: Whatever's selected on the
tower or a K9AY loop connected to the RX-in line on the back of the K3S. I
don't' have a separate antenna to feed another receiver so I guess the idea
is to take signal off the IF from the P3 out, yes? Like I said, I'm really
very old-school and I need help getting up to speed with all this stuff. I
migrated from a Mark V last year and the learning curve on the K3S is still
as steep as Mt. Everest for me. Any help greatly appreciated,
please'n'thanks!

it might be.

I am getting the text on the KX3 screen and TEXT is enabled on the PX3, the

text should be, but nothing shows up. 

The PX3 seems to work on in all other respects..

 

I get digest emails, so a direct email to n...@woh.rr.com
  with any help would be appreciated to see if I can
