[Flexradio] I recovered from the Fatal Error syndrome!!!

[Tim Ellison]

OK, here is the skinny.  After reading all the posts today on the Fatal
Error Syndrome, it kept occurring to me that something in the video
driver / DirectX  arena was probably the culprit, so I focused my energy
there.  I ran DXDIAG, an it said everything was fine and dandy, but I
had my suspicions since it took forever for the Direct Draw test to
start.  Bottom line is that Windows really can't 100% fix itself.  You
have to do it for it. After trying just about every combination of
driver setting, I decided to punt.  

1.) I downloaded the latest version of DirectX (again) and installed it.
It was the entire package of DirectX, not the updates.
2.) I downloaded the latest video driver for my NVIDIA GeForce 6200
3.) I went into Device Manager and I wiped the video driver clean off
the system (files and Registry settings).  Rebooted when it asked to.
4.) Once the system rebooted, I allowed it to install the standard VGA
driver.
5.) Then I ran the NVIDIA driver install program and rebooted (again)
6.) Once it rebooted I re-ran DXDIAG and Direct Draw was MUCH faster.
Direct 3D ran about the same.
7.) I crossed my fingers and sacrificed an effigy of Bill Gates in the
back yard (this step is optional, but it makes you feel a lot better)
8.) I started Preview 8 and low and behold, it loaded. The PowerSDR
Setup Wizard never looked so SWEET!

Let the testing begin.

Re: [Flexradio] Congratulations Phil Covington

Wow, I like that microscope, vision problems is a big issue with me, I
find it very difficult to work with all this SMT stuff. But if you are
going to work with new chips, SMT is about the only choice these
days.
Last week I started setting $75 a week into a special account so I can
burn some money at Dayton and other hamfest, I can see I'm going to have
to up that figure.
Phil, what is the working distance of that microscope? I have a real nice
Nikon 6.5X loop for looking at 60mmX70mm negatives, but it's useless for
working on a board, it's only good for inspection, you have to get too
close.

[Flexradio] ADD'L INFO

[Philip M. Lanese]

Been using DirectX 9.0 since 11/29/05
 
Phil, K3IB

Re: [Flexradio] Preview 8 DirectX

[Philip M. Lanese]

With the ATI FireGL X128 this occurs when I drop the hardware acceleration down
three notches.

With SDRConsole beta Preview 8 running, GDI+ selected, I move slider three
notches to:

"Disable all DirectDraw and Direct3D accelerators, as well as all cursor and
advanced drawing accelerators."  "Use this setting to correct severe problems
with DirectX and accelerated applications."

If I switch from GDI+ to DirectX, all functions work but the noise floor 'grass'
is no longer refreshed and moving the setup pane around the desktop erases to
black the entire display area of the console, grids, left over noise floor
grass, etc. but the little red cursor controlled display numerics still work and
follow mouse as normal (frequency, amplitude, etc.).

Attempting to shut down and restart P8 results in "Fatal Error" about 1/2 way
thru initialization with the following JIT info:

Object reference not set to an instance of an object.
  at PowerSDR.Display.Init(t)
  at PowerSDR.Console.InitConsole( )
  at PowerSDR.Console .. ctor(String[ ] args)
  at PowerSDR.Console.Main(String[ ]args)


Otherwise, CPU = 3.06G P4, 1G 400 MHz DDR, gets the following mileage:
Beta P4:  10 to 15%,
Beta P8, GDI+: 5 to 18%,
Beta P8, DirectX: 2 to 10%  (only cursor controlled display numerics active)
No SDR program running: 0 to 2%, mostly 0%

Re: [Flexradio] Preview 8 Fatal Error

Hello all.
 
Just found this link with instructions to check 
your video display and DirectX install to
see if it is set up correctly to run DirectX as 
well as set up 3D Device object.
 
The utility is called dxdiag.exe. The instructions 
are at this link.
 
http://support.microsoft.com/default.aspx?scid=kb;en-us;191660
 
I ran the tool and found that I passed all tests. 
Preview 8 still does not work, but
I think I have ruled out my video card, and version 
of DirectX as culprits.

Eric has done a great job with the first release with DirectX.  MS's
documentation of DirectX and WDM KS is either very very sparse, or
where it is documented, it is incomplete and/or just plain wrong.  I

[Flexradio] DirectX vs. RealVNC

[Duane - N9DG]

Uh, oh... I have discovered that choosing DirectX effectively
breaks the use of WinVNC with PowerSDR. With GDI+ it does
work rather well where the panadapter displayed remotely via
VNC is *very* usable on a 100Mb/s network. With the new
DirectX setting the panadapter doesn't really update unless
you are doing something on the screen when using the default
"VNC hooks" setting in the VNC server. It can be made to
refresh ~4 times/second by setting VNC server to "poll the
desktop" for changes though it is not nearly as smooth as
GDI+.

1. Has anyone else been using VNC with PowerSDR?

2. If so what have been your experiences?

Scorecard update:
DirectX with VNC = LOSS :(

Re: [Flexradio] One man's POS is another Man's dream

[KD5NWA]

Well I have exactly the same POS video card in all my PC's, a Matrox 
G450 dual-head video card (same drivers also), I just installed Beta 
8 in the PC I will be using for SDR work, and it works fine after a 
fresh install and switching to DirectX.


Unlike my previous try, in this Dual-CPU Dell PC trying DirectX made 
a big difference, the average load of the two CPU's went down to 1/2 
of the usage before switching to DirectX. By the way, after running 
for a while I ran FFTW3 and it further lowered the CPU usage, the 1/2 
usage figure is after running FFTW3.


Unlike the single CPU system whose CPU load goes up and down on a 
regular basis, the dual CPU load is fairly steady at around 10%.


Life is good when you have a POS video card that doesn't blow up on 
your face. Besides right now I'm so over budget that buying a video 
card is out  of the question.

There should be included in your distribution a new fftw_wisdom.  It
really must be run with FFTW3.  It can take a while depending on your
CPU.  I think in the 64 bit CPU case it will make a difference.  Let us
know if it does not.  If you have the correct wisdom,  when you start it
you should see it go up in increasing FFT size in the forward and then
again in the backward direction.  On the bombing on initialization bug,
I have no clue what that is and Eric will have to deal with it.  If
deleting the database does not fix the problem,  I am lost.

Have a great weekend.

Re: [Flexradio] TX Image Rejection Question

[Robert McGwier]

No. That is what I meant by "we are not doing this correctly".  The 
issue is, and always has been,  the monitoring demands of the 
audiophiles and many others.   When we had two port (single stereo 
channel output) cards, we could not provide both monitoring and 
offset.   You are quite correct that it is a good thing, and we 
should've already done it.  The single stereo card folks will just have 
to lose out on this immediate and large improvement in TX quality.  The 
four port cards allow us to do this easily.

Aren't you doing your Tx at the same DDS frequency as the Rx (where

Or, does the software switch the DDS frequency when you go from Tx to 
Rx? (which raises a whole host of issues with spurs and the like).

[Flexradio] A bit more on Preview8 and DirectX

[Ross]

Just to add to the pile of data, (or pile of 
whatever)
I tried DirectX again and instead of allowing it to 
cancel, allowed it to continue. The CPU usage immediately
dropped to about 6 +- 3 ie 3 to 9 a big reduction 
from the 20+ under GDI. However the panadapter lost its grid totally, the 
panadapter
screen went white but the trace still continued. 
Mixw stopped receiving but that could have been a separate problem.
Being positive Eric, you are on the right track 
just a bit more "tweaking".
Good luck and thanks for the software, it is 
getting better all the time.

[Flexradio] Preview 8 DirectX

Hi Eric,

>From my earlier report I indicated that the text in the display modes

I went into the code and commented out the try..catch block around the
hardware rendering setup.  So it either tries to do only software
rendering or none...   When it does software rendering the text and
grid displays are now readable on my system.  I guess the conclusion
is that the problem lies in how hardware rendering in the different

considerable decrease in CPU usage as compared to GDI+ on this system.

One possible solution is to add another combo box under the Setup
Driver Engine combo box and maybe let the user select between
hardware, software, and none for the rendering instead of
automatically allowing hardware rendering if the function does not

Re: [Flexradio] Beta 8, DirectX, new AGC, use of FFTW3

[Bob Tracy]

Well,

My problem with DirectX is only in the debug mode.  I installed fresh
software for P8, tested both runtime and executable, and then ran
fftw_wisdom on both.  The runtime codes is working just fine in both cases.
I notice a definite decrease in CPU usage after the console has been running
for a few minutes.  It is initally higher, in the 30-40% range, and then
drops into the 3-6% range.  RX sounds very good!

Sure wish I had thought of running the executable yesterday, might have
saved Eric and I a lot of time but when you get focused on a problem you
sometimes can't see the forest for the trees.

I suspect my problem is with my copy of the DirectX SDK.  I "updated" it on
the MS site after I started having problems but the updates from my original
version to the current version are documentation only (so I've been told).
Unfortunately, there is no way to uninstall DirectX and start over again
short of a hd format and reinstalling the OS.  The good news is that I can
run in debug in the GDI+ mode so I'm not dead in the water as far as CAT
development is concerned.

Hope everyone finds a solution as easily as I did :>)

[Flexradio] 1.4.5 Beta 8 - Scorecard

[Duane - N9DG]

Scorecard:

DirectX = TIE, no discernable difference either good or bad.
Total machine CPU usage has been runing <10% (typically
6-7%), still running in the excact same range using DirectX.
FWIW the first versions of PowerSDR I ran about a year ago
were more like 25%. There have been no significant changes to
the machine HW/SW over the last year.   

New AGC (esp. gain) = WIN, can once again hear all that I can
see on the panadapter, it's been a few versions since I could
do that. Woohoo!!

Pollyphase FFT = TIE, no discernable difference either good
or bad, running fftw_wisdom.exe did not change anything.


Player stats:

CPU = AMD Athlon XP 3000+

RAM = 1GB

Video = NVIDIA GeForce4 MX Integrated GPU (64MB) running
@1024x768 75Hz, 32 bit color quality.

Sound Card = Audiophile 192

OS = Windows XP Home / SP2

Re: [Flexradio] Arrrrg Release Notes omission: polyphase FFT

[Robert McGwier]

We can increase the resolution here by factors of 2 with the 
computational complexity also going up by a factor of 2 each time.  
ALSO:  if you go as much as twice as deep (a factor of 8 rather than a 
factor of 4) the increase in video latency becomes absolutely 
immediately apparent.  You will hear a sound and a noticeable amount of 
time later,  the display will correspond to the sound.  There is not 
such thing as a free lunch.

[Flexradio] One man's POS is another Man's dream

[Robert McGwier]

We have some clear cut examples of very good video cards that are 
blowing up.  This is Eric's first DirectX offering.  It is just not 
trivial to deal with these Microsoft tools so I would wait until some of 
the dust settles on all this before you give up on your card.  We 
definitely have some issues with this release .  We have one clear cut 
case of FFTW3 not improving but hurting (the 64 bit CPU case) since GDI 
was used.


There should be included in your distribution a new fftw_wisdom.  It 
really must be run with FFTW3.  It can take a while depending on your 
CPU.  I think in the 64 bit CPU case it will make a difference.  Let us 
know if it does not.  If you have the correct wisdom,  when you start it 
you should see it go up in increasing FFT size in the forward and then 
again in the backward direction.  On the bombing on initialization bug,  
I have no clue what that is and Eric will have to deal with it.  If 
deleting the database does not fix the problem,  I am lost.


Have a great weekend.

Let me say this once since it has not been made explicit.

Whether or not DirectX helps you or hurts you is COMPLETELY dependent 
on
the quality of your video card and its driver.  If you driver and 
video

card do lots and lots of texturing and rendering, etc. in hardware, it
will give you a huge cut down in CPU.  If you own a POS video card, to
match the POS mobo for the sound card, expect no help from this
setting.  Please continue to use GDI.

(POS == piece of slime, otherwise substitute your favorite)

On my laptop,  the CPU %   moves up and down from 1% to 10% with much
more variance than before.  However,  previous to our use of FFTW3 and
DirectX,  it was a steady 40%.  This latest version is an overall
MASSIVE win.

The agc is now the FULL two track specification that Phil proposed.
The implementation has undergone many iterations and the fast track 
came

together in the last two weeks while sitting in my hotel room in
Marburg, Germany.  Frank and I attended an AMSAT meeting there where 
it

became absolutely clear that SDR is the future of amateur radio
satellites.  Phase 3E will use an SDX (software defined transponder) 
and
AMSAT's current Eagle proposal is a software defined satellite.  Now 
if

we could only get Software defined launches!

Back to the AGC,  Phil lives in the land down under.  This means that 
he

and I are inverted!

Phil suggests setting the fast attack threshold to twice that of slow
track to target the same signal.

Phil used AGC voltage (the more negative, the more AGC limiting).   I
use gain.  Furthermore,  my gain is voltage multiplier.  His AGC was 
dB
and inverse gain.  The results were like those of the JPL engineers 
who

spoke metric on one side and feet/yards on the other and sent the Mars
mission into the dirt.   This is entirely my fault and Phil's spec has
been fine since day one.  I really like the new sound this gives.
Thanks so much to Jeff for his constant probing of the agc and his
EXTREMELY useful software analysis and critical remarks.  Also to Dale
for his continued testing and remarks and measurements.  Four days ago
they gave me their latest comments and measurements on overshoot and I
hope we successfully captured the necessary changes in release 8.  If
not,  we are still learning.  What I can say is this is a sweet 
sounding

agc now and we should all send our thanks to Phil, VK6APH.

Eric is busting his rear end on getting DirectX to work.  Like all
things, Microsoft works extremely hard to obfuscate as much as
possible.  I am becoming more and more convinced that you get the 
secret
keys to the kingdom of their documentation, and probably code 
examples,

only as a result of attending this huge thousands of dollars developer
courses.  Monopolies stink.  There is absolutely NOTHING worse than 
the

documentation for WDM-KS.  DirectX is slightly improved with the
"managed directX" is an abomination.  It silently wrecked the floating
point coprocessor and we were pointing the finger at FFTW3 until Eric
found a page or two full of complaints about the idiotic silent 
behavior

and then implemented the (behind the hidden handshake and thousands of
dollars of training) hidden flag that stops this behavior.

[Flexradio] Further comments on preview 8

[Ross]

Firstly thanks Bob, and all the others who 
contributed to preview 8. The software changes to the AGC and the correction for 
digu are a great
improvement. keep up the good work, its a fantastic 
system.
Secondly, unfortunately there are a few problems, 
showing up.
I am running a top of the line system, (just to 
drive the SDR1000) 
comprising an Athlon 64 dual core 4400, an very 
high spec PCI-express SLI video card, with its own ram, plus 2gb ram on the 
motherboard.
Preview 8 loaded, but it now takes between 20 to 
24% of the CPU, whereas Preview 7 and earlier, only needed 10-12%.
I cannot run DirectX I get the standard Exception 
error, but GDI works ok.
 
Best wishes to all

Re: [Flexradio] Preview 8 doesn't like my computer?

[José Dumoulin]

I have no problem with Preview 8 (GDI+ or
Directx). I imported the Preview 7 database.

I prefer to stay with GDI+ because, with Directx, the percent
CPU used is around 38 instead of 4.

I saw no difference with Preview 7. I must confess that AGC and ALC
setup are
still obscure to me.

Abyway the SDR has it's own computer.

Subject: [Flexradio] Failure of Preview 8

What did I do wrong!!
ran the .exe file like all the others. It made a directory and
installed itself. Clicked on the ICON on the desktop and "Fatal Error"

It

says Object reference no set to an instance of an object.
at PowerSDR.display.Init()
at PowerSDR.Console.initConsol() etc etc.

First time using PowerSDR that this happened to me. Preview 7

works

OK as well as all the others.

Any Suggestions?

Re: [Flexradio] TX Image Rejection Question

[Robert McGwier]

Jim:

Sorry I was not clear:

2 transmit ports could output processed audio for monitoring and 2 could 
output 11025 KHz for sending to the radio.  It will have the hookup we 
currently use for the Delta 44 but we are sending the same thing to both 
ports, one has AF gain control on it for monitoring and the other has 
PWR control on it.  Otherwise, it is the same audio.


This will move us away from the 1/f,  DC mixing components, etc we 
currently get (at a low level but present nevertheless) and it will move 
the image from (say) a few Hz to 20+ Khz away making image rejection 
more easy on TX.

I'm not sure what you mean here..

I assume that if you have a high performance audio card, you'll use 2 
of the inputs for the Rx and 2 of the outputs as the Tx.


But that won't allow you to calibrate the Tx side (unless you assume 
the Tx and Rx responses are the same, which might be true for the 
audio side on the card, but is almost certainly not true for the audio 
side on the SDR1000).  On the other hand, it might be "good enough".


It's conceivable that you could "loop back" the Tx into the Rx; they 
actually join at the 4:1 transformer, after all. That's a convenient 
calibration plane, at least for the image rejection issue, because 
it's on the RF side of the QSE/QSD.  Unfortunately, even though you 
could calibrate the receiver, and then use that to calibrate the Tx, 
it looks like the Tx/Rx control line disables and enables the 
detector/encoder, with no way to defeat this (short of changing the 
board).


For that matter, it might be "good enough" to calibrate/equalize just 
the audio card with an audio loopback.

Re: [Flexradio] wave files

[Mike Naruta]

Hi Mike,


You may have already discovered this, but here's
how to record your IF to a wave file.

On the menu bar click on Wave.

In the Record section, click on the Record button
to start the recording.

The button turns yellow and you are now recording
your IF until you click the Record button again.
Note:  this makes a BIG file.

After you have recorded one, you can play it back.

Note:  the recorded file is in the location where
your software was installed.  When you upgrade to
a newer version, the new files are recorded where
the new version is installed.  When you go to play
back a file from an older version, you will not see
it unless you browse to the older version's folder.

You can find the directions in the SDR-1000 Operating
Manual version 0.7 at page 116.

Re: [Flexradio] Beta 8, DirectX, new AGC, use of FFTW3

[Robert McGwier]

Larry:

As I said,  DirectX implementations depending heavily on the hardware 
and the drivers.  When I engage directx with my ATI Radeon 9800, I get 
an immediate factor over 2 drop in CPU ticks!  When I use it on my 
Nvidia card at work,  I get a larger drop.  When I use it with the ATI 
Radeon Mobo card on my laptop, the CPU drops on average by a factor of 
two.  Coupled with the use of SSE2 in the FFTW arithmetic,  this winds 
up being a factor of FOUR on my laptop.  This is due to faster graphics 
plus fast computation of the filters.


These numbers are huge as you can imagine.  The graphics systems was 
clearly a severe limiting factor in the performance of the code system.  
There was really no way for us to know what we would find at the end of 
the day due to the large variance in cards and drivers.  For the time 
being,  the implications are clear:  Use the graphics system that gives 
you the best overall performance.  The DirectX (really managed DirectX) 
is new to us all and will take time to work out in detail (hopefully not 
as long as the sound card issues took for us to completely understand).

[Flexradio] New SCOPE

[Robert McGwier]

Nothing proves to me how much better the agc action is in this release 
than Eric's new scope display. Eric has done a very nice job with this.  
We can see the individual dits and dahs and the design of the agc comes 
through.  Phil gave us a very nice technical description for the the agc 
action he was after and I think we have come close to that (the 
exception is the slope calculations).  But the thing that this scope 
shows absolutely clearly is that we are beautifully shaped the agc with 
the "lead in system" implemented in the agc which is a major addition to 
the Phil specification.



Let me do some ascii art that I did for Jeff earlier.


indx  fastindxsndx
| slow channel learns >|
  |-fast learns-->|


Time and samples come in on the left and then proceed to right (without 
actually moving, done with a circular buffer and pointers).  So indx 
marks the new sample.  The slow agc channel learns what gain should be 
applied over the time span marked slow channel learns.  This is 3 time 
constants of the attack time you have requested (my selecting fast, med, 
slow, long agc).  The time constant for the fast channel is 1ms, the 
decay time for fast is 3ms."fast learns" is two time constants long. 

So now the 3 time constants of slow learning and two time constants of 
fast learning arrive at the past sample, sndx.


What is applied is   the MINIMUM of the slow agc gain and the fast agc 
gain and this application occurs at the sample marked by sndx.  This is 
output.  The intent of this is clear.  If a large signal arrives and it 
is short duration,  we want the signal reduced quickly but smoothly, the 
way the old agc worked (but more smoothly) and then with the short time 
constant, decay and get out of the way so that the average signal value 
stays high.  This improves things a lot on transmit.  On receive, we can 
easily hear the slow decay of the breathing agc system.  The downside is 
that 3X slow agc time constant latency is introduced.  To me, it is 
worth it.  You can easily see all of this latency in scope.


We have the potential for a huge selection of agc settings.  We have not 
really implemented a reasonable way to control all of that.  That is for 
future work by Eric.

[Flexradio] Max CW Power

[Richard Stouffer]

I read in the manual that the Max power for CW should not
exceed 25 watts, however, I can’t TX CW at settings greater that 12 or 13
Watts without the high SWR legend popping up.  I have this even if I have equal
reading for both “Fwd Pow” and “Rev Pow”.  Am I
misinterpreting the Fwd and Rev as a rough SWR indicator, or is there a
calibration problem?  Where do I start to isolate the problem?

Re: [Flexradio] Failure of Preview 8

[Tim Ellison]

Jerry,

I see a common thread here.  I am running an AMD Athlon 64 bit
processor.  I have both .NET 1.1 (it is embedded in Win2003) and 2.0.
My video card is also a NVIDIA GEforce 6200.  And last but not least,
the Delta 44.

I wonder if it is hardware?

goes brain dead and I must reset and set the CAT. (Use N!MM or WRITELOG

Abyway the SDR has it's own computer.

Must be something simple and some one will point out

Let me say this once since it has not been made explicit.

Whether or not DirectX helps you or hurts you is COMPLETELY dependent on
the quality of your video card and its driver.  If you driver and video
card do lots and lots of texturing and rendering, etc. in hardware, it
will give you a huge cut down in CPU.  If you own a POS video card, to
match the POS mobo for the sound card, expect no help from this
setting.  Please continue to use GDI.

(POS == piece of slime, otherwise substitute your favorite)

On my laptop,  the CPU %   moves up and down from 1% to 10% with much
more variance than before.  However,  previous to our use of FFTW3 and
DirectX,  it was a steady 40%.  This latest version is an overall
MASSIVE win.

The agc is now the FULL two track specification that Phil proposed.
The implementation has undergone many iterations and the fast track came
together in the last two weeks while sitting in my hotel room in
Marburg, Germany.  Frank and I attended an AMSAT meeting there where it
became absolutely clear that SDR is the future of amateur radio
satellites.  Phase 3E will use an SDX (software defined transponder) and
AMSAT's current Eagle proposal is a software defined satellite.  Now if
we could only get Software defined launches!

Back to the AGC,  Phil lives in the land down under.  This means that he
and I are inverted!

Phil suggests setting the fast attack threshold to twice that of slow
track to target the same signal.

Phil used AGC voltage (the more negative, the more AGC limiting).   I
use gain.  Furthermore,  my gain is voltage multiplier.  His AGC was dB
and inverse gain.  The results were like those of the JPL engineers who
spoke metric on one side and feet/yards on the other and sent the Mars
mission into the dirt.   This is entirely my fault and Phil's spec has
been fine since day one.  I really like the new sound this gives.
Thanks so much to Jeff for his constant probing of the agc and his
EXTREMELY useful software analysis and critical remarks.  Also to Dale
for his continued testing and remarks and measurements.  Four days ago
they gave me their latest comments and measurements on overshoot and I
hope we successfully captured the necessary changes in release 8.  If
not,  we are still learning.  What I can say is this is a sweet sounding
agc now and we should all send our thanks to Phil, VK6APH.

Eric is busting his rear end on getting DirectX to work.  Like all
things, Microsoft works extremely hard to obfuscate as much as
possible.  I am becoming more and more convinced that you get the secret
keys to the kingdom of their documentation, and probably code examples,
only as a result of attending this huge thousands of dollars developer
courses.  Monopolies stink.  There is absolutely NOTHING worse than the
documentation for WDM-KS.  DirectX is slightly improved with the
"managed directX" is an abomination.  It silently wrecked the floating
point coprocessor and we were pointing the finger at FFTW3 until Eric
found a page or two full of complaints about the idiotic silent behavior
and then implemented the (behind the hidden handshake and thousands of
dollars of training) hidden flag that stops this behavior.

[Flexradio] Arrrrg Release Notes omission: polyphase FFT

In release notes for version 8,  we made a serious omission.


Go into CW mode.   Go into the 500 Hz filter and tune in a CW signal or 
carrier, etc.  But be sure you choose a CW note that is not one with 
1000 Hz wide key clicks like the FT-1000.



Click on the setup panel.  Click on Display tab.  On the right edge in 
the center.  This is a check box.


click on Polyphase FFT enable box and watch the CW note on the display 
get 4 times narrower.  This is the exact same polyphase ratio used by Alex.

I finally hooked up a microphone and made my first ssb qso with my 100w
sdr1000.  The tuner worked fine trimming the small mismatch on my r6000
vertical on 7153kHz. As I was talking and watching the power meter it
was some times hitting 120 watts and I think some parts may have been
getting hot.

What is the accepted procedure for limiting the power output? The power
