comparing P3, LP-Pan, SDRPlay, others?

Jim Hoge-2

Greetings,

I have yet to be convinced I need a panadapter for HF but its use for weak signal 6m use is what has my attention. That said, I have seen the P3 and an LP-Pan demonstrated but nothing else. I realize I am probably trying to compare apples to oranges but how do these stack up against each other? Can anything  besides the P3 be used to point and click for QSY? I think the P3 lends itself to my rudimentary comfort level with computers but I do have good tech support in my wife. That said, fire away....

Tnx,
Jim, W5QM

It is very useful for search and pounce operation in contests, and for
finding a slot to call CQ. It is also useful for understanding the shape
of a DX pileup.

I find that it helps build a mental picture of the band that I was never
able to do simply by listening. Having owned one together with the VGA
adapter, I would be very reluctant to go back to ears only operating on
any band.

Jim:

How can you enjoy a radio without a pan adapter or spectrum display nowadays? After using the P3 for close to six years, I would never even consider a radio without something  with that functionality. Still thinking about it? Hello, just don’t think anymore. Just use the plastic and enjoy ham radio again!

Premise: It is more enjoyable working them than not-- the quicker the
better.

Let's face it DXing is a competitive undertaking.  Besides power and
antenna dB's, there is another "space race" war going on.

Technology has equipped many station with panadapters of some sort.
They have proved so useful that those without them are at a huge
disadvantage.

So to stay even with the crowd, one almost has to have one.

DXpeditions have been impacted negatively.  They can't listen on the
same frequency for more than one or two QSO's.  That frequency becomes a
wall of unreadable stations.  Thus they move their receive frequency
between QSO's.  Finding that pattern is really hard without a
panadapter.

Don't shoot the messenger.

Re: comparing P3, LP-Pan, SDRPlay, others?

Richard Fjeld-2
In reply to this post by Guy Olinger K2AV

Not all pan-adapters are created equal.  Some suggestions;

Compare the images of one to another.

Look for images that are sluggish and exhibit a delay between what is
heard and what is seen due to the computer involved.

Also look for false images that are mirrored, etc.  (That may take
experience to notice.)  The same image may be appearing in more than one
place on the band at the same time.  Best done at the widest bandwidth
setting.

Compare the bandwidth capability of the various units.

Compare the features included in the various units.

Compare the ease of operation.

Never used an LP-Pan, but it appears to be a sweet instrument and lots
of folks like it.

I have a P3 w/ SVGA option (will add TXMON soon).

IMHO, a panadapter is no longer optional.  I use it every time I am on
the radio...  regardless of the band.

I use it to monitor a band segment when running a net.  Use it to find
signals when DXing, et al.  Use it for weak signal work (the screen is
better than my ears).

Use it for all kinds of stuff...

The P3 is excellent for HF but its "point and click" facility is far too
slow to catch fleeting openings on 6m.

To keep watch on the 6m beacons, CW and SSB requires a frequency span of
at least 200kHz - and wherever a station may appear, you need to jump
onto that frequency *immediately*. For a 6m DXer, that is the practical
test case.

A mouse can point-and-click accurately at the opposite side of the
screen within 2-3 seconds, almost independent of the size of the jump.
If a station is calling CQ and you're using a mouse, you can probably
arrive in time to catch the callsign - so if it's a new one, you can be
the first to answer. But the P3 requires a button-press before you can
even begin to twiddle the small knob, and then it takes at least an
order of magn... oh never mind, the station's gone. The P3 fails that
practical test by a wide margin.

Having suffered that scenario too many times, when I purchased a second
K3 for use mostly at VHF I decided not to buy either a P3 or a KRX3.
There are far better possibilities using conventional SDRs with computer
displays that have the *true* point-and-click facility.

After some experimentation the 2m station now uses an SDR at the
transverter IF, 28MHz, which is where the front-end gain and SNR are the
highest (the SNR at the K3 IF port is not as good, which is very
noticeable with weak signals). The SDR-IQ, Funcube Dongle Pro+ and
SDRplay all gave comparably good waterfall displays but the SDRplay has
the major advantage that the frequency span can be expanded beyond the
more usual limit of 192kHz. For example, European VHF/UHF contests
require 250kHz for full coverage - and those extra kHz are important,
because stations do spread out to the extreme edges of the range.

Integration with logging software is obviously vital. At present I am
using Eterlogic's VSPE port emulator to provide a additional USB links
to the HDSDR program and to N1MM+. HDSDR offers the valuable option of
the Winrad waterfall palette which is specifically optimized for finding
weak signals, and it automatically recognises the K3's transverter
offset and allows single-click QSY of either VFO A or VFO B. If HDSDR is
linked to VFO B, the K3's VFO B knob can then be used to tune the SDR.
All the other functions of the K3 remain unaffected, so the SDR is
effectively behaving as a second receiver. A simple switch allows the
audio output from HDSDR to be fed into the RH earphone, effectively
replacing the KRX3 for SO2V operation. Meanwhile N1MM+ automatically
keeps track of all events, and can provide voice and CW keying in the
normal way.  

This setup is still in the experimental stage, not yet ready for a full
cookbook description, but it is showing geat promise. None of this is
new, but it was new to me  (special thanks to GM4JJJ for pointing me in
the right direction and making it click). Above all, it does seem to
meet the *practical* requirements for VHF/UHF DXing and contesting.

Re: comparing P3, LP-Pan, SDRPlay, others?

Wes Stewart-2
In reply to this post by Jim Hoge-2
I use an SDR-IQ and SpectraVue software* to look at the K3 IF output. The
software has a K3 interface option built in that knows all of the frequency
offsets between modes and tracks the K3 center frequency perfectly and
seamlessly.  You can tune the K3 with the mouse wheel or point and click.  
Theoretically it can be used as a second RX, however latency might be
disconcerting, at least it is to me.  But I don't have a second RX in the K3
either since I have a hard enough job listening to one frequency without trying
two :-)

The SDR-IQ has been discontinued but used ones still show up. (~$350-$400)  
There is a higher priced replacement but I can't speak to that one. The P3 crowd
will argue that my approach requires a computer (and a USB port), but who
doesn't already use one for logging anyway?  I run LP-Bridge to share the USB
port with the SDR, K3, logging program, MMTTY, etc.

A secondary benefit is that the SDR-IQ makes a decent (but not stellar)
standalone RX and can be used (with care) as a very accurate spectrum analyzer.  
I used my second one to measure the TX IMD of both my K3 and K3S. My data
correlated with Elecraft's to within a dB or less.

* There is other SDR programs out there and I've tried most of them but I'm
sorry, the authors of the other packages simply don't think like real people do
and I find them simply awful.

When I was trying to work my friend Ned, AA7A, operating RTTY at VP8STI I was
looking for his pattern.  It took about an hour to figure out that he didn't
have one! I finally stuck to one frequency and he eventually found me.

When I saw him later I mentioned it and he confirmed that after each QSO he just
randomly moved the dial.

I love my P3.  I've been a ham for 36 years (active for all of them).

I've had my P3 for over a year and a half and simply don't know how I ever

Although I really like using a panadapter, which I made from a Softrock
Lite II for $21.00 and an external USB sound card for about $50.00, it was
a lot of fun using my K1 during a recent NAQCC sprint.  Panadapters are
nice, but not absolutely necessary in my opinion.

NAP3 + Softrock IF + built-in stereo line in (96kHz samplerate) is best
bang for the buck if you want to see the band, point & click and solid
integration with K3 and other software.

The combo here is:
- software: N1MM logger + NAP3 + LP-bridge
- hardware: Softrock-IF, built-in soundcard on 5 year old laptop (can
run at 192kHz) or back in the shack an 8 yr old vista-Dell with $50
soundcard.

Use the point and click when scanning the band and looking for certain
stations or QRM free frequencies.

Can anything  besides the P3 be used to point and click for QSY?
If you want to point and click to EXACT frequencies, I recommend CW Skimmer with LP-PAN.  Skimmer is the only SDR program I'm aware of that calculates exact frequencies for its decoder dots.  When properly set up (which takes some doing), you can dead zero beat decoder dots simply by clicking them.  This was one of my gripes about the P3.  It's difficult to position the cursor exactly and then press the knob without applying any torque which will slightly shift the frequency.  

Another useful feature of Skimmer in large pileups is its "599" function.  You can watch the display for a magenta 599 to appear and then click to the exact frequency of the last station worked.  I've worked stations in very large pileups without ever actually listening to the pileup itself.  I do dial in a small XIT offset so that I'm not dead zero beat with others using the same technique.  For determining the pattern that the DX is using to work the pileup, it's simply a matter of watching the 599s to appear to see whether the DX op is working up the band, down the band (and by how much) or random tuning.

Here's a recent post about how to do this (note that a KRX3 is required) including a link to the Skimmer page which showing the 599 function in a very large pileup:

Both CA Skimmer and Rocky have this feature.  All you need to do is click within a pixel or two of the desired signal and it pulls the frequency to zero beat the signal.  I have only used it on CW, so I don't know if it works for other modes.  It is similar to the CWT function.

If the P3 and PX3 don't have this feature, they should!  It would complement the "Elecraft Quality" that they build into their radios.

As I said "Skimmer is the only SDR program I'm aware of that calculates exact frequencies for its decoder dots" and I haven't researched newer programs since 2011, so there are probably others now.  

BTW your comment assumes the calling station in question is still there for CWT-like behavior to work.  The 599 function will send the K3 to the frequency of the *last* station worked in the pileup, even though he's probably no longer transmitting.  

Here's another neat thing you can do with Skimmer and a script to control it via a mouse wheel.  I use the wheel to quickly tune up or down the band in contests.  No need to mess with carefully positioning a mouse, pressing a knob, etc.  Note that this is Blind Skimmer mode (no callsign decoding) which is legal for unassisted contest categories.

I use Win4K3 with CW Simmer. I can see what the band looks like in the
spectrum display in Win4K3 and refine my selection and decode call signs
for 1/2 the sampling rate of my sound card in CW Skimmer. Together they
are a powerful combination. Both control the frequency tuning of your
radio.

HiWin4K3Suite can also qsy cwskimmer on VFOB allowing split operation which is great for pileup.  Cwskimmer alone does not have this functionality. 73 Tom va2fsq.com

True.  However if you have a KRX3, CW Skimmer can use VFOA for TX/RX pileup and VFOB for RX DX frequency *without any other program needed*.  Since I already have a KRX3 (necessary for diversity), I created a simple Macro to program VFOA for TX and VFOB for RX (see my previously referenced link for the Macro) allowing Skimmer to jump the TX frequency to Skimmer's 599 decoder dots.

If you have SKIMMER on the subrx's IF, you also need a different RIG
file for SKIMMER to do this.

It's really neat though.  Send SKIMMER spots to the logging program.
Click on them there and VFO A goes to the spot.  Click on spot in
SKIMMER and VFO B goes to the spot.
