A button I never use ... that fixed it.  I must have bumped it while 
re-mounting the data switch on top. Thanks,

Re: [Elecraft] P3 Waterfall

[Bob Wilson, N6TV]

I recently saw this happen on W6NV's P3 after upgrading the firmware from a
very old version to the most recent version in one jump, or perhaps I
accidentally removed power from the back of the P3 while it was on, while
simultaneously bumping one of the front panel buttons.  Reloading the
firmware and doing multiple power cycles did not fix it.

Instead, if you can get to the P3 menu, go to the RESET option and press
the knob.

Or, if the P3 Utility still talks to the P3, go to the command tester and
type:

#RST;

You may then find that the REF LEVEL is set way too high at 0 dB.   Adjust
REF LEVEL back down to about -120 dB and it should be back to normal.

[Elecraft] P3 Waterfall

Re: [Elecraft] P3 Waterfall Off with SVGA Waterfall On???

[Alan]

To have waterfall enabled on the external display and off on the 
internal display, or vice versa, requires three things:


- P3 firmware 1.50 or later

- The "SVGA WfEn" menu entry set to either "Waterfall on" or "Waterfall 
off" as desired.


- Toggling the DISPLAY key on the P3 to turn on/off the waterfall.

Re: [Elecraft] P3 Waterfall Off with SVGA Waterfall On???

[Cady, Fred]

Hi all,
The SVGA WfEn toggles the SVGA waterfall on and or or tracks the P3's main 
display.  So you can set it on and the turn the P3 on and off independently.  
That's how I have mine set up.
Cheers and 73,

[Elecraft] P3 Waterfall Off with SVGA Waterfall On???

[Ken Widelitz]

The bottom of page 30 of the P3 manual shows a photo with the waterfall
completely off on the P3 with the TX Mon option. The text immediately above
that photo states "Note that in this illustration the waterfall display is
turned off so the spectrum display and the waveform display fill the main
part of the screen."

 

I see the menu item under SVGA where I can turn the waterfall on or off. I
don't see that option for just the P3 display. What I would like to
accomplish is have the waterfall on the SVGA monitor, but not on the P3
display. Is that possible?

 

73, Ken, K6LA / VY2TT

Re: [Elecraft] P3 - Waterfall Marker?

[d...@lightstream.net]

Hi Steve,

I agree that a dot or small vertical line at the bottom of the screen
would work great for this purpose.

The bottom white 'frame' already has small vertical 'tic' marks on it. I
think adding a small tic or dot just beneath that bottom frame would do
the trick. That way, the active part of the screen isn't being painted.

Dale WA8SRA

Re: [Elecraft] P3 - Waterfall Marker?

Hi,

I use 50 Khz or more span only to get an overview. Normally i only use 10
khz and never had problems turning the marker to the waterfall trace, so
that I could catch the station next time it came up.

[Elecraft] P3 - Waterfall Marker?

[Steve Ellington]

Am I doing something wrong or is this just how it works?

I have the P3's waterfall marker turned on. The "marker" slowly crawls down
the screen toward the bottom. Moving the Select knob drags the top of the
marker and the rest slowly follows drawing a snake. Cute but...huh?

Question: What good is this? The reason I would want the marker is to
quickly set it on a signal that has already progressed down the screen. I
can't because basically there's no marker. If I just wait for it, desired
signal is gone.

Why can't the marker in the waterfall just be an extension of the one in
the spectrum so you can use it? Is there some technical reason?

I'm used to using software for this and none of them work like this.

Am I missing a setting somewhere? I've looked hard.


Thanks for listening;

Steve N4LQ

Hi Steve, 

That's how it works.  If you don't want the signal to roll off the bottom of
the screen, use Freeze to stop the screen from updating or turn averaging on
to slow the screen updates and provide more history.  

Kind regards, 

Paul

Re: [Elecraft] P3 - Waterfall Marker?

"Freeze" locks up everything including the marker so how does that help?

When searching for signals we might see one on the waterfall that is half
way down the screen. We want to mark, click or do something to get us
exactly on frequency so we can either wait for the signal to return or try
calling QRZ however there doesn't seem to be a way to get on frequency
other than a rough guess.

At first when you mentioned "freeze" I was excited but now I find that
using freeze makes the situation even worse since nothing responds. I'm
just looking at a locked up system!

The marker needs to be independent of the displayed materialLike a
mouse on virtually any other SDR software.
Is that something Elecraft can do or is it impossible with this hardware
configuration?

Thanks

Re: [Elecraft] P3 - Waterfall Marker?

[Al Lorona]

I think what Steve is asking for is a dot (non-line) marker at the *bottom* of 
the waterfall and that doesn't have persistence (doesn't "leave a trail"), so 
that he can line it up with a scrolling signal and then QSY to it before it 
disappears off the bottom of the screen. It's actually not too bad an idea, 
considering that signals are always heading to the bottom of the waterfall, but 
currently the marker's latest position is at the top of the waterfall.

I can usually get close enough to hear the station by eye without a 
marker, either on the P3 or on a 24" VGA.

calling QRZ however there doesn't seem to be a way to get on frequency

At first when you mentioned "freeze" I was excited but now I find that

The marker needs to be independent of the displayed materialLike a

Is that something Elecraft can do or is it impossible with this hardware

Re: [Elecraft] P3 - Waterfall Marker?

[Steve Ellington]

I always used fixed mode. Nope doesn't help.
There needs to be a marker at least at the bottom of the waterfall so you
can mark the signal before it disappears and shift frequency to it.

[Elecraft] P3 - Waterfall Marker Question

[Steve]

Am I doing something wrong or is this just how it works?

I have the P3's waterfall marker turned on. The "marker" slowly crawls 
down the screen toward the bottom. Moving the Select knob drags the top 
of the marker and the rest slowly follows drawing a snake. Cute but...huh?


Question: What good is this? The reason I would want the marker is to 
quickly set it on a signal that has already progressed down the screen. 
I can't because basically there's no marker. If I just wait for it, 
desired signal is gone.


Why can't the marker in the waterfall just be an extension of the one in 
the spectrum so you can use it? Is there some technical reason?


I'm used to using software for this and none of them work like this.

Am I missing a setting somewhere? I've looked hard.


Thanks for listening;

Steve N4LQ

Re: [Elecraft] P3 waterfall curser operation

[Paul Saffren]

Hi Allan,

The short answer is that the hardware doesn't support it.  The long 
answer is that the video chip we are using on the SVGA accessory board 
limits us to how many "video layers" we can combine to produce the video 
image.  Overlaying the cursors on to the waterfall would require an 
additional layer which we do not have.

Re: [Elecraft] P3 waterfall curser operation

[Paul Saffren N6HZ]

Hi Smith, 

The P3/SVGA waterfall cursor is incorrectly named, it should read 'waterfall
marker" in the release notes.  The cursor is not shown in the SVGA
waterfall, but if you turn on Marker A or B, they will appear.

Why is are waterfall cursors not available?  They would be much more useful

Re: [Elecraft] P3 Waterfall

[Alan]

You can increase the waterfall sensitivity by adjusting the REF LVL to 
place the noise right at the bottom of the spectrum display and then 
increasing the SCALE setting.  The same REF LVL and SCALE settings are 
applied to both the spectrum and the waterfall displays.  For further 
details, see the PX3 User's Manual section called How to Set Up and 
Interpret the OX3 Display.


To erase a FN key setting, use the FN Erase menu function.  You can also 
over-write it by assigning a different function.

All of your concerns are answered in the manual. The P3 is a very 
powerful and versatile product, and the SVGA board increases its 
capabilities. It's scan width can set to any value between 2 kHz and 200 
kHz. Amplitude range can be set between about 10 dB and 80 dB. The unit 
can be calibrated to the voltage at the K3's input terminals (a signal 
generator is required). Both amplitude and waterfall can be averaged or 
not, and average settings are adjustable. There are separate settings 
for the P3 display and the external display. The frequency resolution is 
quite good, and is improved by a factor of 10 or more by the separate 
FFT used to drive the SVGA output.


Here's a link to some lab quality spectrum measurements I've done with 
my P3/SVGA. k9yc.com/FTDX5000_Report.pdf The P3/SVGA combination has 
frequency resolution that is roughly 100X better than my HP 8509D.

Re: [Elecraft] P3 waterfall legend?

[Peter Eijlander (PA0PJE)]

Hi Gary,

The signal you are referring to is a STANAG 4285 military transmission 
from Turkey. The curly things you see in the spectrum is in fact 
selective fading in the sent spectrum, which is roughly 10 kHz wide.


quote
10.1102 MHz-USB-Izmir, Turkey Turkish Navy - STANAG 4285
unquote from:

http://qrg.globaltuners.com/?q=STANAG%204285o=qthm=0m=1

The RTTY on 10.101 is DDK9, A German Meteo service sending SYNOP to 
(probably just a handful now, I suppose...) ships. Germany seems to have 
enough money to maintain a 10 kW transmitter active 24/24 for ancient 
services.

[Elecraft] P3 waterfall legend?

[Gary Smith]

Is there a resource on the internet where you can look at different 
screenshots and see what the source is for some of the signals that 
are translated by the waterfall? I see so many different geometric 
forms based on the nature of the Rf and they are a mystery to me.  CW 
is pretty easy to detect, same with RTTY. Some of the other digital 
signals have their own appearance you see often. There are some 
signals I have heard before but now to see them portrayed on a screen 
as in a waterfall, they are surprising to me and I'd like to know 
what they are. 

For instance; I was on 10.1 MHz and there's that constant commercial 
RTTY station around 10.101 but next to it around 10.112 is another 
much larger signal and it takes a lot of bandwidth. At first I 
thought it was some new digital mode I haven't yet seen but it is 
continuous so it must be commercial. It looks to be a series of 
curled sections spiralling with each other. I've heard this signal 
before but just now with the P3 with its SVGA larger output, am able 
to see it.
 
http://doctorgary.net/p3screen.jpg

I'd like to be able to identify what kinds of signals make the QRM 
that we hear but can now see with the waterfall display.

Gary

[Elecraft] P3 Waterfall

[W4GRJ]

This is more a educational question. When using the manual notch to take out
a constant carrier, I can see the notch take out the carrier on the DSM780
waterfall however, the carrier is still visible on the P3 waterfall. Just
wondering why you can't see the same notch effect in the P3 waterfall.
Thanks,
Jack

Re: [Elecraft] P3 Waterfall

This is because the P3 waterfall is taken from the IF output. The notch is done 
with the DSP on the 15KHz IF, not the 8215KHz IF.

[Joe Subich, W4TV]

  The manual notch is NOT within AGC loop.

It's not a matter or the notch being within the AGC loop (although
it should be for other reasons).  The P3 is fed from the output of
the first mixer - before the roofing filter.  That's the only
place to get a 200 KHz +/- bandwidth.

Re: [Elecraft] [P3] Waterfall Display

[Bill W4ZV]

 using/interpreting the waterfall display?
 

I searched but the following is the best I could find (which isn't great):

http://en.wikipedia.org/wiki/Spectrogram

A waterfall is basically a spectrum (signal amplitude versus frequency) but
with the added dimension of time (amplitude versus frequency versus time). 
A waterfall is most useful for detecting signals that are not continuously
present.  For example a weak DX station only sending short bursts when he's
answering callers that may be calling split on a different frequency.  Or
for extremely weak signals fading in and out of noise (e.g. QSB on the low
bands or meteor scatter at VHF).  For weak signals buried in noise, your eye
would probably never detect these in a spectrum display but they become
quite apparent in a waterfall display.  Once you know exactly where a weak
signal is, then you can tune your receiver to the exact frequency and begin
to apply filtering in both the radio and your ear/brain to copy it.

I use waterfalls mainly for weak signal CW on the low bands.  They're
especially helpful for signals at or below the noise floor.  I understand
they also work well for digital (not my thing except for the original
digital mode---CW).  They don't work as well for wideband and time-varying
signals like SSB.  If you seldom operate CW or digital modes, I doubt you
would find a waterfall very useful.  

I prefer a waterfall only mode for my applications and will probably use
that when Alan eventually makes it available on the P3.  As the P3 stands
now, I maximize the waterfall portion of the display, turn MKR on in the
spectrum area only, center it over a waterfall signal just below and press
QSY to identify the station by ear.  

CW Skimmer is another alternative that uses waterfalls exclusively.  Below
are some screen shots of Skimmer's waterfalls (which are unique in their
ability to show CW dots and dashes over a wide dynamic range of signal
strengths):

http://dxatlas.com/CwSkimmer/

I hope this helps but the best thing is to simply play a game with the
waterfall display.  Try setting Ref Lvl just at the noise floor and see if
you can copy the weakest signals the waterfall detects.  When you can,
you'll be ready to work weak CW DX on the low bands or at VHF.

73,  Bill

[Elecraft] P3 - waterfall suggestion

[GLEN BROWN]

The P3 waterfall works just like all others I have seen and used: when you
tune to radio, the old pixels continue to move down the screen vertically,
but do not move horizontally with the tuning.  As a result, the waterfall is
useless until it catches up a couple of seconds later.  If those pixels all
moved horizontally with the tuning, then the waterfall would still be
relevant and helpful in tuning to a signal of interest.  It's only
software.

By the way, what a totally enjoyable addition to a great radio.  Way to go,
guys.

Re: [Elecraft] P3 - waterfall suggestion

[Guy Olinger K2AV]

This is the normal behavior of all waterfall displays I've seen, and
is a very familiar screen behavior.

The cursor is the means of zeroing a signal of interest which then
telegraphs the new frequency back to the K3.

Part of the issue of tuning is that the saved information does not
include frequencies outside the display, so tuning as you suggest
would require filling in zeros all the way down AND further,
performing a second graduated shift of ALL information.  Given the
very fine degree of detail stored, this may be a significant CPU
intensive task using up processor cycles.  Devil will be in the
details, not in the simplicity of concept.

73, Guy.

[Elecraft] [P3] Waterfall Display

I have never used a waterfall display before getting my P3 (sn 155). I used 
 spectrum analyzers before.
Does anyone have a recommendation on an article or some info on  
using/interpreting the waterfall display? 
In the commercial world, never used them just spectrum analyzers.
Oh the P3 works well. There are more signals than I thought out there. Even 
 the ones in the noise.

With very careful adjustment of the P3's Ref Lvl and Scale, some dots and

works with no adjustments necessary.  I believe Alex VE3NEA is using some
AGC to adjust for varying noise conditions and signal levels.

My decoder is much better than either, but it's not for sale.  ;-)

[Elecraft] {P3] Waterfall Resolution

[David Gilbert]

For those who now have a P3 and also use CW Skimmer in one form or 
another, how do the waterfall displays compare on CW for resolution and 
scroll rate?  I often use CW Skimmer in blind mode with just the audio 
feed from my K3 to provide a running visual CW display (about 12 to 15 
seconds on my monitor) in case I miss part of a contest exchange.  It's 
clumsy and MUCH less effective in general than copying by ear, but it 
sometimes helps me avoid asking for a repeat if I miss a character.  Of 
all the various non-SDR applications I tried that are capable of 
displaying a waterfall (Spectrogram, DigiPan, MixW, MultiPSK, etc) CW 
Skimmer was heads above the rest, but the recent comments about the 
sharpness of the P3 display make me wonder if the P3 is potentially 
better in spite of the smaller screen.  With CW Skimmer, visual copy 
above roughly 35 wpm gets pretty dicey.

[Elecraft] P3 Waterfall Averaging

[The Smiths]

I hate to be a party pooper, Allen, but I absolutely HATE having the the 
waterfall average along with the audio scope on ver .031.  
 
It makes the noise floor an out of focus blob and all the code coming down 
through it just a big blur.  I would MUCH prefer to have the upper portion ONLY 
average, and the bottom waterfall just work as it always did before.
If you have others that like that waterfall averaging, perhaps it can be a 
settings that you select WHAT you're going to average. As for now I can no 
longer use the Averaging display.  Thanks,

Re: [Elecraft] P3 Waterfall Averaging

Thank you Alan.  That's just what I needed!  Good programming!

I'm really liking version .031, now that the waterfall situation is not an 
issue. I haven't found any new problems that affect me.  I'll let you know if I 
do. 
 
Any ideas on what we can do to remove the drifting?  I've noticed on 2 units 
now that they all continue to drift DOWN in freq. as the day goes on.

Re: [Elecraft] P3 Waterfall Averaging

[Ed, W9EJB]

Alan,

I am curious about the algorithm you used for the averaging.  Is it just a
straightforward, uniformally weighted average or do you use something more
sophisticated? , e.g., an exponentially weighted average.
