Re: [Flexradio] Lightning Strikes

[Bob McGwier]

Let me help with "it could have been worse".

W5ZN, former ARRL prez, and my good friend, had 160 through 10 Ghz, multiple 
radios, etc and had unplugged antennas and grounded them.  Lightning came in 
and wiped it ALL out, almost total loss.

Re: [Flexradio] Distorted TX audio PWRSDR-2.6.4

[Bob McGwier]

I think what is preferred is what works best for your particular 
computer, 1394 device, etc.


Once you have down how this works,  it is easy to go back and forth and 
change drivers.



Jay <mailto:n...@no5j.org>

Is the "New" driver now preferred over the "Legacy" driver? with my TI 
firewire chipset it's never made any difference which of the three 
(New, Legacy, or TI) drivers is used, they all seem to work the same. 
Prior to PowerSDR 2.6.4, I had the impression that the preference was 
to go with the Legacy driver unless there was better performance seen 
with one of the others. Is it time for me to update my impression 
about which driver should preform the best and switch to the "New" 
driver, and stop relying on and recommending the "Legacy" driver.


I don't want to steer anyone into using the wrong driver.

For my own usage I've been selecting the "Legacy" driver over the 
others based on recommendations I've seen on the reflectors and in the 
knowledge center and PowerSDR release notes. But specific instructions 
from Bob McGwier carry more weight.


And Bob, A Big Thank You! for all you do.

In device manager, click on the device. Click on the driver tab. Tell 
it to update and pick the new driver.


If this looks like a foreign language to you, don't do this without help.

After updating the software in Win7-64 to  PWRSDR-2.6.4 the TX audio 
is badly distorted (did try reset database).   The same update on my 
Win7-32 system worked fine.  When I checked the FW driver in Device 
manager they are both using the 1394 OHCI Compliant Host controller 
legacy driver.  I was surprised since I thought it would use the new 
Flex Firewire driver 4.1.1 .


The FW card uses the TI chip-set and worked fine in previous versions 
of PWRSDR.


I would like to try the new FW driver.  How do I manual install this 
since it did not do this on the update.


Note: using DPCLAT or the Flex program I don`t see any bad DPC`s and 
the Flex program recommend `Normal Mode`


Any suggestionsÉ

Mark:
NB1 and NB2 are intended to aid mitigation of impulsive noise. NR is
intended to mitigate white noise. The hump does not fit what this (or most

Re: [Flexradio] Panafall artifacts and things that make me go, HMMMM...

[Bob McGwier]

Another thing to get used to is the S meter reads the integrated signal
power from the entire passband filter, not just the display power in the
single FFT bin (the few bins)  that goes into a pixel in he panadapter.

This is most easily seen by setting a filter and slowly decreasing the
filter bandwidth by dragging filter edges and watching the meter value
decrease (unless it was already dominated by a very strong signal).

How can you be certain that the listener on the OTHER end is calibrated?  Maybe 
you are perfect and they are off.

Re: [Flexradio] AM with new software

[Bob McGwier]

I always got complaints no matter where we put the ANF.  The ANF is a
complex filter running at IF, and it is BEFORE the agc.  If you notch the
carrier, which the ANF can and does do, the AGC raises the levels of the
sidebands.  This is because we got complaints that when the ANF worked
well,  it took out the interfering tones but they had captured the AGC.  So
it was moved before the AGC.

This is a thing that can be dealt with but with a collection of software
changes and additions but I won't be saying it will be done, only that it
can be done.  This will be decided at Flex Central

Re: [Flexradio] Flex 1500 keyer and PSDR 2.4.4

[Bob McGwier]

It's pretty amazing and the improvements, which have been steady, came from 
both concerted effort to replace the first keyer and impediments to good 
latency in response to keying stimulus AND serendipity!  The last big step was 
a complete surprise realized by Tim, and I will leave it there since it has not 
been conclusively proven (though some of us are certain).  I will say that it 
was an oversight that could have been picked up when we changed from VS2003 to 
VS2008.  Anyway, it really is a remarkably improved keyer.

I have really enjoyed it and so will you.

Re: [Flexradio] Trying to improve DPCLAT, now SDR crashes

[Bob McGwier]

I agree!  GBoost is a well done tool for performance geeks,  mostly gamers,  
who count every cycle and know more than we ever could about how to squeeze  
your machine AND give you control over how far to go and a Meter to show you  
how well you've done. 

I am not sure how good it would be for hunting down a DPC bad actor  
driver/hardware. 

I used it on my old AMD dual core laptop and it ran Flex 5000 at 192000 for  
the first time ever.

Flex lost a strong supporter in Ed White, WA3BZT of Delaware.  He was at
Charlotte, NC at the SVHFS meeting a short while ago and shortly after was
diagnosed with mesothelioma and is now SK.  Ed was a great big kid about
his ham radio, enjoyed life to the max, and was a hoot to be around.  We
were in Packrats together while I lived in New Jersey.

Not to denigrate the F:EX ( I am waiting on a 5000) but as one who has

suggest you look at the Yaesu FT-857, or similar.   This, in the size of a
book, gives 100 watts on all modes, all bands, and you do not need a laptop
unless you are running digital.   You do need 12V.   In most travel

other end modified with a connector to the radio. By the way, on the beach,

The term obsolete just doesn't apply here as it means no longer suitable or  
sustainable for the purpose at hand.


If you were top of your class when in school and a new, smarter, student  
came in, were you suddenly obsolete or merely not the smartest in the class?


Being completely susceptible to "The Brand New Wow!" myself, it doesn't mean  
I will be using my 5000 any more or less, it just means Flex has a new radio  
(that I want to play with NOW!)


Yes, firewire is a limited lifespan product, but for gods sake, I have  
friends still using computers with ISA slots to contest with. I still have  
an ISA slotted machine so I could play with my contest cards) but sadly its  
sitting in the trash heap at the very moment!   If someone is willing to buy  
a PCIe firewire card for their computer, you have a decade or more of buying  
firewire components.


The other "limited lifespan" product is powerSDR. Not its ability to run on  
a computer, or your ability to download it, etc. but the continued evolution  
of new features, etc.  I think this is a Chicken Little issue however. When  
the day comes that Flex cannot/will not continue to develop/maintain it, I  
have an optimistic feeling someone else will. 

Why are we so paranoid that one day the 5000 will become a "boat anchor"  
(but we definitely need a new term for this kind of radio!)?

Burt, et al, Flex 5000 can be used forever pending radical changes in

Firewire, etc may become as obsolete as IBM single sided single density  
251Kb 8 inch floppy disks but if you can find "old" boards to keep your  
computer running  A N D any replacement parts for any failures within the  
radio box there is no reason why a Flex can't last essentially forever.


Saying "half" the radio is the computer and computers are nearly obsolete  
when sold etc. doesn't really tell the story.  Computers get obsolete  
compared to newer offerings NOT because they start to loose function with  
age like we all do.  I have a good friend who is still using the Samsung  
6-8MHz XT clone I gave him last century.  It still performs flawlessly and  
runs Multiplan, WordStar, etc just as good as when new.


Flex radios can evolve and change over time if someone has the ability to  
improve on the software.  This is a giant difference as compared to the  
beloved venerable Hallicrafters of my youth.  Only the future can dictate if  
the Flex radio portion of the equation will become obsolete and unusable.


The 6K is (depending on your predilection for hyperbole) an evolutionary  
improvement over the 5K or if you are a marketing type a REVOLUTIONARY  
improvement but, "I don't think so, Tim.) (Spoken by Al to Tim "The Tool  
Man" Taylor, not THE TIM of flex fame.  The 6K does essentially what the 5K  
does but does it differently and better in some respects. I am not in a  
position to opine on the 6K's obsolescence resistance. After some  
consideration I decided the 6K does not obsolete the 5K any more than a  
Tesla obsoletes my wife's Prius.  Different price points, different  
performance, different sex appeal and both meeting their requirements very  
well but not really intended to race each other or be rated as "Babe  
Magnets."


May Flex and Flexers live long and prosper.

P.S.  I hooked up my new 5K last night and have a few things to figure out

No network protection mechanism worthy of being called such will EVER
survive in the modern environment with a CDN which starts with an SDN.

You need multiple innovations these days and work is already being done in
these areas (most of the IP is declared and protected).

1) A software defined router capable of taking rapid training of new rules
and applying MANY MANY rules more than is currently sustainable by almost
any available commercial router.
2) An AI capable of running both rule based and inference based update of
the state of play and then making the changes to the routing rules.  This
is the only way to be fast enough to ever hope to be useful these days and
those which are surely to follow.

A world with SDN informed by an AI making it a Cognitive DN is doomed to be
as useful as coaxial based 10BaseT ethernet card is today.

Absolutely you can.  Just configure CWskimmer for the WDM-KS driver and 
192K.  You will need to set the radio's sampling rate to 192K also, as 
Direct IQ is directly dependent on the radio's native sampling rate.

Necessary evil.  It has always worked well enough not to spend tens of  
thousands of dollars to replace it.   I was awfully glad when I. first got  
this going but wish we could afford the time to "do our own ". 

It is a big deal to replace all the wires!

"AUDIO SUBSYSTEM ERROR: INVALID DEVICE

Whoops! Looks like something has gone wrong in the Audio section.

Go look in the Setup Form ->  Audio Tab to verify the settings there.

Since VAC is enabled, make sure you look at these settings as well."



The panadapter froze up but audio was still heard.  When I closed the

With the start button dark, I hit the 12m band and hit start.  The radio
came back on, but when I hit the 12m band button again, the error message
returned.  I tried the 10&  20m bands with the same results.  Now these

These are my Audio Tab settings;

These are the same settings I used on v2.2.3 except Driver-MME and Sample

VAC 2:

Closing the software and rebooting does not correct the problem.

A solution to the problem would be appreciated.

Re: [Flexradio] [FlexRadio] Re: Transmit spikes - continuing problem

[Bob McGwier]

I consult for Flex,  did the SDR software with AB2KT with contributions and  
suggestions from many here.


I own only two manufacturers HF radios except for my mobile rig.  I have  
multiple Flex radios and multiple Elecraft radios that I built.


You want to find what most fits your needs and then if you are US, say thank  
goodness for Gerald Youngblood and Wayne Burdick.  They have directly  
contributed to almost ALL of the interesting innovation in amateur radio  
equipment manufacturing and MADE IN THE USA is personally nice to have.
Both are engineering stars and K3 v Flex is to be decided by what fits you  
best.


Snap decisions are not required.  The density of both radios in the US  
certainly allows one to get out of their easy chair and drive to a fellow  
ham's shack and play before spending thousands.  I think it is almost that  
dense in much of Europe. 

I have operated Flex 5000 and Elecraft K3 in contests and watched a novice  
contester use the 5000 and N1MM without any previous prejudices about  
operating contests.  I would say that, for the moment, if you are a  
multi-multi peopled by old contests hands, the K3 wins.  If operate a lot of  
search and pounce NOTHING beats a Flex with its fantastic display and  
filters and ease of finding a spectral hole to drop in.   If you are  
operating digital modes and other interesting experiments and want dual  
synchronous hardware receivers, and many more things, you cannot beat the  
Flex.


You can have my Flex radios and the Elecrafts I built when .. uh ...  
never.

load. I used the new MH-31 mic. The result was SPIKES


I like the receiver, the filters, the screen - but, I cannot tolerate

I will miss the good qualities of the 3000 - but, certainly not the

Hi all

Its that time of the year to be kind to our PCs since they are the
touchstone for all of our radio fun!!

Click on the start button, then click on All Programs, scroll to the
Accessories category and then right click on the Command Prompt. When the
pop-up menu comes up, select "Run as Administrator".

When the "DOS" shell comes up, type in "SFC /SCANNOW"

This is the System File Check utility and it will go through all of the
system files and make sure they are intact and working well. If it finds a
problem, it usually will replace it from a copy of all files Windows keeps
in a cache directory.

It will take some time (longer if you have a lot of programs), but this is
one utility that you should periodically run.

To be honest, Bob's machine is underpowered also and it will be interesting
to see if he is still happy with that part of the machine 6 months from now.

The original computer I started selling 3 years ago had a 350 watt PSU and
that was just the bare minimum and if anyone plugged anything extra into
one of its slots or a power drawing USB device, twilight-zone time.

Just as an aside, the ASUS power supply calculator says Bob's system needs
a minimum of a 350 watt system (and thats a minimum).  Try it yourself at

This is not the board that Neal recommended, but it is the "little

Today (December 20) NewEgg has the Asus M4A88T-M motherboard for

That is a mini-ATX board. I am using the M4A88TD-V EVO, a "regular" ATX
board, which has more expansion slots. The integrated video (same on
both) is not for gamers, but it's fine for PowerSDR.

Re: [Flexradio] AMD chip

[Bob McGwier]

My experience with the AMD II-X4 machine from Wally world is identical to
Brett.  I ran 192000 with 256 and the rest at 128 and I NEVER ONCE heard  a
glitch with VAC running WDM-KS,  8000, 512  and any of JT65-HF, FlDigi,
MMTTY, MMSSTV along with logging programs DXlab with spot collector,
dxview, etc. I used VSPmgr and Eltima serial cables.

I used N1MM with keying during the Stew Perry and it never blinked.  Near
QSK, etc.

I hope the quality of the parts holds up in the machine because it is a
fantastic performer.  Its only "lack" is VGA connector Nvidia video.  The
Windows "experience" is 3.7 and this is completely dominated by graphics
performance.  I keep my display update to 10, but I could run it higher if
I thought it bought anything.  I never once even started GBoost.  There was
no need.

So, I am very pleasantly surprised, especially after getting a refurbed
earlier model for more money from Tigerdirect and having it arrive DOA.

I think this is the thing that drives me personally to scratch my head
until I have at most three hairs left on top.  I cannot explain why this
inexpensive machine performs the best of anything I've plopped down in
front of, but I will take it.

Yes, absolutely.  The faster the convergence, the more likely disturbances
to the carrier from fading and interference from other signals, noise, and
low frequency modulation will impact it.

Let me thank you right now for all the great work you have done with

"...doing all the filtering and demodulation with perfect

I wonder if Flex, or anyone with the ability to do the coding, ever 
considered these four enhancements that definitely interest me:


1. Costas loop detection for receiving pure DSB with suppressed 
carrier. No transmitted carrier is required for a Costas loop sync 
detector. It depends on the audio null in the Q channel for phase 
lock. It makes DSBSC practical and supposedly does better than a 
carrier lock sync detector when propagation is turbulent, even on AM.


2. Provision for transmission and phase-locked reception of SSB with 
a pilot carrier down 20 dB or so. This was used by TMC for HF SSB 
broadcast relay gear and gave SSB a clarity, with perfectly aligned 
harmonics, that current ESSB techniques cannot (though they can come 
close with rubidium or GPS frequency standards).


3. Use of "selectable sideband sync detection" using the phasing 
technique to cancel the interference in either the upper or lower 
sideband of an AM signal. (Since there is no significant desired 
audio in the Q channel, the desired audio is _not_ cancelled from 
either sideband.) This gives a 6 dB s/n advantage over the "drag the 
filter edge" technique of chopping off one sideband when it is 
interfered with. This would also lend itself to a fantastically 
effective kind of binaural reception on AM: LSB interference in the 
left headphone channel; USB interference in the right channel; 
desired AM audio -- and _nothing but_ desired AM audio -- in the 
center. I have experienced this and it allows the brain to process 
the signal in a way that allows _much_ better intelligibility.


4. Adding the ability to see the modulated RF (really IF) on the 
receiver scope, instead of just the demodulated audio. This tells 
you a lot about the received signal, especially on AM, and would be 
a very valuable tool.



With best Yule wishes,


Kevin, WB4AIO.

Re: [Flexradio] FlexRadio Digest, Vol 80, Issue 17

[Bob McGwier]

Absolutely NOTHING.  That is the REASON for having the (synchronous AM) SAM
detector.  Maybe we should not have included the AM detector at all but I
thought it would be of interest to compare them side-by-side so the
differences in signal processing could be seen.

When the selective fading takes out the carrier,  the exact same distortion
occurs on the AM detector that would happen if you overmodulate an AM
carrier, it is the same phenomenon mathematically.  On selective fading HF
channels it is more complex distortion, but nevertheless the same.

SAM zero beats the signal and then detects it as a DSB signal and
coherently adds the sidebands.  Since the carrier is tracked and "replaced"
overmodulation doesn't occur.  Further, since the DSB out of SAM is not run
through an ugly nonlinearity to detect it,  you do not get IMD and other
ugliness.  It does have nonlinear processing, just not as nasty as a full
wave rectifier followed by a filter AFTER the IMD damage and multiplication
by noise has occurred.

If what we are experiencing is AM being hit by selective fading,  then use
SAM.

Re: [Flexradio] Misinformation about k3 being srd

[Bob McGwier]

Now there we can all most certainly agree.  If they don't do the S part
often enough to make it useful or at least exciting,  then the utility of
the S part is to the manufacturer and not the user.

One of the things I was involved with for Flex was the TNF.  I made an
addition to the waveform processing software and the guys at Flex turned it
into a work of art and all of us got a brand new radio with software
change.  Before that we turned a mediocre CW effort I was involve with to a
really good break in effort done by the guys at Flex and .  we got a
brand new radio.

The TNF is the penultimate effort for me...  and I am working hard on the
ultimate for me for the year now.  FINGERS CROSSED,  I still have 16 days

Re: [Flexradio] Misinformation about k3 being srd

[Bob McGwier]

Stand alone does not preclude software defined.  I offer up as evidence the  
Ettus USRP E100.  It is completely stand alone but runs GnuRadio on an  
embedded processor.


The ability to change the code running on ANY ASSOCIATED processor doing the  
signal processing is what defines an SDR.  It doesn't matter if it is the  
user or the manufacturer.   If the entire waveform processing can be changed  
WITHOUT changing the hardware,  and only changing software, it is most  
assuredly software defined.


The K3 fits this description.  It is NOT as versatile as the FLEX system in  
this regard but it is an SDR.  In the case of the K3, DSP chips are used.   
In Ettus hardware, FPGA are used and either PC or embedded processor is  
used.  Flex uses the PC for its amateur radio equipment and FPGA and PC for  
its commercial offerings.

All,

There are many hams that swear up and down that their K3's are software  
defined. I try to explain to them that their k3 rigs are software enhanced,  
but not truly software defined.


Many hams including some very bright engineers that are in the club still  
think that their k3's are SRD.


I try to explain it that it is not srd as it can be run standalone, where a  
Flex cannot.


I still get that glazed deer in the headlights look when I try to explain  
SDR.


Any suggestions?

Those are great little boards, and often quite cheap when you find them on
eBay.  I've built up about half a dozen boxes using those boards for under
$100 total including memory, an IDE-to-CF adapter and CF card (as a cheap
solid-state HD replacement), case, and 12V DC power supply.  They're in use
as mountaintop Linux/Asterisk machines serving as repeater controllers and
remote base controllers.

Would I build my Flex machine around one of those boards?  No, though I
can't say I've tried either.  Apparently from what you're reporting, if you
run the OS lean enough, they've got enough horsepower to do the job.

Tell Carter and Kay that Jeff WN3A said hi!

Re: [Flexradio] Heil Headset and FLEX-5000

[Bob McGwier]

Thanks to everyone who helped.  I got time to go over to N3AO last night
and we got his headset working.

My Heil Proset set is Tango Uniform.  I think there is a break in the cord
as neither element works.  This induced aggro which led to an improper
setting in the aggro environment which prevented the perfectly good headset
from showing it was working.

The 5000 is working perfectly in all modes on my Intel ATOM computer.
Since N3AO, N3KN, N1SMM, and I will be doing contesting and some serious
algorithm testing,  I am moving the new AMD II-X4 over there to use.

When my refurbished AMD II-X4 arrived from Tigerdirect it was DOA.

When I found out they had depleted their stock, I looked at Walmart and
found this

http://www.walmart.com/ip/Acer-1TB-PT.SGM02.002/16608489

It was the same price,  brand new,  with better graphics 

I will report after the contest this weekend.

The RCA adapter plugs are for the back panel inputs (line in and PTT) so we
can make sure the front plug is working.

Re: [Flexradio] Heil Headset and FLEX-5000

[Bob McGwier]

Thanks guys.  I think we are having a serious problem with the headset.
Carter has two of the adapter plugs.

I am REALLY hoping it is the headset and not the rig.  I'm going to take
over a Traveler and RCA phono plug adapters and make sure we have the mixer
settings right which is of course new to Carter as he has gone from Flex
1500 to 5000 fully loaded.  It is a learning curve!

He is getting my poor help as N1SMM and I are going to operate the 10m
contest with the Craigies this weekend.

73's and thanks for helping us.

When you run the installer for PSDR 2.2.3,  SELECT FLEXCONTROL as part of

Re: [Flexradio] Why doesn't MON button work in AM

[Bob McGwier]

In the case of FM, you get the fully FM'd carrier but you need to offset in
case there is no modulation because the AC coupling in the QSE would block
it so that much is indeed the same.

Re: [Flexradio] Why doesn't MON button work in AM

[Bob McGwier]

In order to get the carrier through the QSE (the exciter), it must be offset
from zero.  This means you would hear a loud heterodyne and offtuned double
sideband speech.  It would not be very pleasant to listen to.

Guy,

I do not think that I de-sense anyone's receive capability with my 25 watts and 
indoor antennas. I typically get signal reports of -15 dB and I do not believe 
that I have ever received one better than -09 dB. I only asked the question 
because I was curious as to why I could not increase my power beyond about 
25-30 watts without invoking the ALC. I did not intend to run more power when 
using this mode as I am well aware of the problems too much power output can 
cause, including "splatter" when people let their ALC take over.

I do not take your comments as being "snippy", but I do not think we should 
pursue this topic on the Flex lists.

Ed,

Are you serious?

Understand that JT65 is a WEAK signal mode; one the biggest problems is people 
running far too much power and causing de-sensing.

Please do a little research on this mode before proceeding; and try running 5 
Watts.

I don't mean to be snippy but...

Re: [Flexradio] high pitched squeal Flex 1500

[Bob McGwier]

Have you somehow set your "IF Offset" in the setup panel to something near zero?

There is sometimes a DC offset that dies after transitions.  The slow decay is 
caused by the large capacitor in the AC coupling.  It is gone after a couple of 
seconds and is not audible or even impacting unless you have zero IF or near so.

Re: [Flexradio] CPU Utilization Spike When FM Is Squelched

[Bob McGwier]

Through magical incantations learned from a logical trial and error
process.  That is what you call it when it is fixed,  you don't understand
WHY the fix works, but you just know it does.

Re: [Flexradio] Off topic: Hard Drive

[Bob McGwier]

My experience with 2011 differs.  While admitting completely that I am not
an "average user" and have 30+ years of computer programming and user
experience,  I do not have trouble navigating the GUI.

I have used Acronis with BlacX dual drive machinery to clone failing
notebook drives,  desktop drivers, server drives, etc.  through firewire,
USB, e-Sata, and more and  it just works.  I have not found a single
bug.  Now there was a major update just before I got the BlacX and the
program update and maybe this repaired many of the problems Alan presents.
 I know this,  I respect Alan a lot, and so be cautious.  Don't destroy
(overwrite) the old drive before you have tested the new one.  A "wipe the
old one" is an option during clone.

JUST SAY NO to the wipe.  You can always deep zero it later and repeatedly
and format, etc.

I  agree with Ignacio.  Acronis True image is all I use to copy/clone hard

Re: [Flexradio] Notch Filter and PB tuning?

[Bob McGwier]

My apologies to all for being so busy my mind was half asleep.  I am really
up against it at work.
.,
ANF is completely DISABLED in CW.   I cannot remember a time when it was not
but as you can tell, my mind can go off track when multitasking.

This is by design because we wanted ANF to operate reasonably rapidly on
interfering tones and this seemed inconsistent with CW.

I can only promise that all of this stuff in adaptive LMS (ANF, NR, etc.) is
under active consideration.

It is really straightforward.  THERE IS NO PRE_EMPHASIS OR DE_EMPHASIS.  It

"Incorrectly handles" is the wrong phase.

It would.  The only thing that we need on CW is the manual notch, which I

[Flexradio] Firewire Driver NOT legacy after SP1 installed

[Bob McGwier]

About the time one of the recent updates from Flex came out,  I starting
having Blue Screens of Death on Windows 7 Professional x64 SP1.

So I was blaming it.  HOWEVER, contemporaneous with the Flex Beta code
install,  Windows came out with SP1.  It updated lots of things, including
going BACK to the "newer superior" driver.  SIGH, Microsoft.

I sent a dump to a couple of people and they pointed me here.


http://www.osronline.com/page.cfm?name=analyze

It analyzed the dump and
immediately told me that it was the new 1394 driver and NOT the legacy
driver.

I went here:


http://kc.flexradio.com/KnowledgebaseArticle50433.aspx?Keywords=legacy+driver

Followed the instructions and now all is well.

Re: [Flexradio] N1MM VAC Audio

[Bob McGwier]

Here is how I have solved the problem with OTHER programs which misbehaved.

I made one of the VAC cables have one be the default SYSTEM sound card for
playback and another for recording.

(Control Panel, Sound setup, make the cables as described).

This will remove your external speakers from the system sound hookup so this
is usually a temporary thing only.

Restart N1MM and see if it will connect to the default system sound card by
default now.

The other ends of the cables, as appropriate,  attach to PSDR.

NO GUARANTEE but I have yet to find a program that this did not fix.  YMMV!!

Re: [Flexradio] Yaesu Production Suspended

Man, FUKUSHIMA?

As in Fukushima that holds the Dai-Ichi nuclear power plant?  I would expect
them to NEVER be able to reopen that plant.

This is not good news for amateur radio.  Competition in Japan and in the US
has brought us to a level of radio technology that many of us NEVER believed
we see and at really good prices.  You can buy a great radio right now for
about the same dollars (even after inflation) that I did in the late
1970's!

I hope they make a come back.

Re: [Flexradio] why am I seeing this ?

[Bob McGwier]

Ed:

The Flex equipment, the TX included, is a baseband SSB mixer.  We inject the
transmit signal high side.  You will see the image of this low side in
another receiver.  BUT, please note HOW FAR DOWN IT IS FROM THE MAIN SIGNAL.
 It way below the legal requirements and you need to be very close to hear
it.

Re: [Flexradio] Some used Flex-5000s on the market

[Bob McGwier]

I agree with Bill on this.We have seen and been a part of hunting down
signals much weaker than this on 160m because DX are typically right at the
noise floor.  We have mounted campaigns to get the offending commercial
transmitters to fix their mess.  It is simply the right thing to do and now
it has been done.

I am as certain at Bill's observations this morning,  the problem is fixed.

Re: [Flexradio] FLEX5K Drops Amplifier

[Bob McGwier]

CPDR on, and set to 1, is very light compression.  It is IMPOSSIBLE for it
to overshoot.  If there is overshoot with that on, it is a hardware spike.

I suggest an experiment with CPDR on, set to 1, to see if the ACOM stops
tripping.  This would isolate it to the DSP sections working on the digital
version of the signal.

Re: [Flexradio] FLEX5K Drops Amplifier

[Bob McGwier]

Writing complex code systems such as PSDR is like pushing on jello, one of
my favorite analogies.  I get the pleasure of doing this in multiple code
bases but PSDR and GnuRadio are the ones that jump to mind when I worry
about consequences because of the number of people and equipment impacted.
 GR was particularly bad when the bleeding edge on all tools was always
insisted upon by the leaders and if it broke applications? "it is open
source go fix it".

Re: [Flexradio] FLEX-5000 160m CW spur ECO

[Bob McGwier]

It fixes both sides.  The opposite spur was weaker and less problematic
since it was lower than the image in every case tested.

Fewer than ten owners complained to Flex.  It is fully realized how many
heard the problem and how many competitors laughed behind their hands or
even out in the open.

I know Bill remembers as I do,  how many years we suffered, without so much
as an acknowledgement of the Yaesu key click problem and we all bore 100% of
the cost over multiple models with their "everyone will continue to buy"
attitude.

This is exemplary behavior on the part of Flex in comparison.

I listened to mine, and I listened to W5ZN while I was there, on both sides
of the channel.  It much lower. I will not claim numbers.  W5ZN is measuring
and will publish numbers independent of mine.  That is as it should be.  My
opinion?  It is fixed once and for all.

Re: [Flexradio] The CW revolution?

[Bob McGwier]

I wrote the original mess (the key handler inside computer) and I can tell
you I HATED IT from day one.  Now MUCH changed after I wrote it.  TC Systems
released their full "pal" handler and "midi" was no longer required.  The
driver and interface got better and better and better.  But I made a very
big mistake.  There were three asynchronous clocks in that thing and no way
to keep them all straight at all times.

The new keyer does away with the much of the problem by relying on the
correct clock for the base timing, and compressing the necessary events in a
good way to handle low impact through the system to maintain state and give
you tone.  This is a COMPLETELY new keyer, literally written from the ground
up.  I didn't understand it for two weeks, and then all of a sudden got it.
 By then, Steve and Eric were half through the basic state machine and it
has taken a long time to track down and eliminate all of the ugly band aids
we place on the old code to handle the mess, and to fix up corner cases
introduced by the new code.

I made a few hundred contacts in the ARRL on my 5000,3000, and 1500 and all
were FLAWLESS CW.  ON PURPOSE, I didn't use a logging program, but my
bencher hex paddle.  It was like night and day from before.  This is a major
breakthrough and will end completely this set of complaints and can only get
better as things are tweaked.

Re: [Flexradio] Flex 1500 Panadapter

Good idea.  Lots of people were unhappy that CW did not show up on the
panadapter during transmit because of the way we did it before the guys in
Texas rewrote the whole thing.  I neither want nor desire to see it on the
screen with the exception of looking at the keying sidebands during
adjustment.

[Flexradio] Apology to Cornell Drentea, Larry Wolfgang, QEX, etc.

[Bob McGwier]

Have you ever done something in heat which you wish you had not done 
later? Consider these:


http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/2007-November/020003.html

http://lists.openhpsdr.org/pipermail/hpsdr-openhpsdr.org/2007-November/005905.html

Cornell wrote a series of articles on his Star 10 transceiver design for 
QEX.  I consider the entire series a work of art and clearly based on 
Cornell's long and illustrious career as a design engineer.



“Dear QEX Editor:

Please allow me to send my sincerest possible admiration for Cornell 
Drentea's Star 10 transceiver series.   This is the kind of article I 
would hope we see regularly in QEX.  The entire effort is a testimonial 
to the life time's experience Drentea has instilled into
the effort. I admire Mr. Drentea’s technical effort and presentation and 
the extensive list of accompanying references.  I always knew Mr. 
Drentea was a

skilled engineer.  May I add my voice to the chorus who really like
the direction and content and evolution of QEX.  Doug Smith was doing
a great job and it is clear this tradition will be improved upon.



 My best 73's
Bob McGwier
N4HY"

was sent to QEX after the last installment.

I strongly objected to what I considered commentary in article 1 in this 
series.  I wish I had sent my strongly held view to Larry and Cornell 
directly.  Unfortunately I did not.


I did and still do believe that article 1 should NEVER have been 
published in that form.  I have since seen QEX be managed VERY well and 
edited with great skill by the brand new editor at that time, Larry 
Wolfgang.


To Larry and Cornell, I give my sincerest apologies for my intemperate 
remarks.  If anyone considers anything in my notes to forums in the 
links above as defaming the character of Cornell Drentea,  you are 
mistaken.  I do not know anything about Cornell Drentea's character so I 
have nothing to defame.  He has an illustrious career as an engineer and 
having owned and operated amplifiers designed my Mr. Drentea, I consider 
him to be a good and valuable engineer and amateur radio operator.


Sincerely,
Dr. Robert W. McGwier
Bob, N4HY

[Flexradio] 2nd Edition

[Bob McGwier]

The 2nd edition of the REALLY expensive ($29.95) SDR book by friend and

contains important additions (OFDM, more filtering, all known errata 
fixed) and I recommend it highly.

Well, Stan & Wayne:

First, Stan, let me say that I'm 71 plus and I've always felt blessed 
because I had a mother and grandmother who made sure I had "scientific 
toys."   I really do believe that their attitudes make it possible for me to 
accept not only technology but new directions in it.  As I've said many 
times, whenever I fire up one of my SDR radios I give thanks that I have 
such a marvelous resource and feel guilty because so many great ham radio 
operators do not!  I don't try to argue the relative merits of SDR vs. knob 
and button radios.   I quickly decided that joining that argument was the 
same as doing business with relatives or arguing the relative merits of 
religion or disagreeing actively with the XYL.   All are pointless.   The 
first time you "mouse" those sliders and buttons to pull a signal out of the 
mud little doubt remains as to where the truth lies!

Re: [Flexradio] QSK -- It's not...

[Bob McGwier]

You would be wrong  about some of the things you say.

When I operate outside of my car.  CW. I have top tens in DX 
contests, my cw speed is 40 wpm with good copy, 50 wpm in "contest mode" 
and I have been a developer of software for the Flex radios since the 
3rd month of their existence.  When I still cared, I was on the honor 
roll in only one mode, CW.


I cannot stop the hype writers from doing their job and I did not get 
to review early copy of ads, but PowerSDR 1.X has always been a decent 
semi-breakin radio at best.  The web pages and ads no longer MENTION QSK 
so far a quick look just showed me.  The early ads did in fact mention 
QSK without understanding that this had a huge number of implicit 
declarations, just as you have mentioned.


PowerSDR 2.0 switches from TX-RX for receive in more than adequate time 
for QSK.  Keydown to RF out is under 20ms.


There are issues dealing with agc memory across transitions which we 
have put down the list for PowerSDR 2.0 in order to do other work which 
Flex feels is higher priority for the release of PowerSDR 2.0, such as 
full support for Flex 1500,  Flex V/U, diversity/phased array reception 
with the Flex 5000 and some other things which are less important.


PowerSDR 2.0 and its plusses and minuses and current efforts are 
discussed in FlexEdge reflector, not here.  But let me say this much. 
HUGE strides have been made in moving the software towards full QSK 
operation.  So I will only say stuff here to dispel the incorrect 
interpretation you make about what it is we are doing or what we care 
about.


From our tests, we believe the hardware will switch back and forth in 
well under 10ms and we are spending serious time in figuring out how to 
cut transition time and transitory response.  We have reduced all of 
that to 1/3 of what it was before in PowerSDR 1.X.  The switch times are 
as good or BETTER than Elecraft K3, Orion 2, ICOM 7800.  We have two 
software ONLY issues remaining to make it QSK and that is going to take 
some sofware engineering that we do not want to do so the hardware 
mentioned is fully supported before Dayton.


Best wishes and it really is like Gerald is fond of saying,  you are 
going to be able to download software soon, and have a new radio.

Hi, Mike...

Read your blog. As a long-time CW operator (licensed ~1946), and having
owned both TenTec and Elecraft rigs with perfect QSK, I was really
deeply disappointed in that aspect of the F3K -- it is a typical
"semi-break-in" rig. I had a fair amount of trouble using it with my
paddles, so shifted over to the keyboard. It is a more or less
reasonable CW "semi-break-in" rig when used that way, but it is still
obvious that the designers were SSB or AM types that did not use CW in
their ham activity. I hope your comment about pSDR 2.x is right, but I
don't hold out much hope, reading the reflector and all the jazz about
audio quality, etc. The only saving grace for CW is the digital filter
system...as you say, it is absolutely superlative.

For a long time I was reticent about making noise over the lack of CW
capability. I finally did so, more in the way of criticizing the ads'
wording about break-in than anything else. I see that the latest web
page ads only specify "semi-break-in."

I think it is important to comment or even complain bitterly about the
lacks of the F3K in this regard. Amusingly, I did see a comment by an
owner of an F5K, who used the dual receiver to provide a kind of
break-in. Unfortunately, we poor cousins don't have that option. Another
comment on the reflector was from an op who claimed that full QSK was
just an annoyance! Go figure.

I personally couldn't give a hang about "audio quality." I'm not in the
broadcast business...just give me a carbon mike salvaged from a WW-2
fighter! But since we come "to praise Caesar not bury him," I thought
your blog struck a nice balance. We wait impatiently for Ver. 2.x (along
with our F1.5K)!

That is job number one after the changes to make sure we didn't mess

Re: [Flexradio] Flex-5000A

[Bob McGwier]

There is one serious stand out that fits your needs.  DXLabs is written by one 
of the finest programmers around.

Dave has taken this task of providing quality software in for years.  He 
natively supports flex radio cat.  I have used no other for a decade at home.

it is a huge suite, doing much more than logging.  I use SpotCollector, 
pathview, integrated with dxatlas cwskimmer and in and on.

Best yet?  He does it as a service to ham radio.  Try it first.

I am considering using a logging program on the same Vista machine as I

Re: [Flexradio] Will Flex-1500 have wide FM?

[Bob McGwier]

That was not my question.  as a VHF/UHF operator I am aware.  I asked if it was 
legal to be wider than nbfm.

The principal difficulty with our FM system is the lack of any pre-emphasis and 
deemphasis (audio shaping).  At the request of several people, specifically 
some in Europe, we narrowed the deviation to make the radio and software legal. 
 Thus my question.  It was a serious one, not flippant.

Bob,

Apparently you are of the opinion that VHF activity is limited to sideband
and FM repeaters. There is plenty of 2 meter simplex action in New England,
both horizontally and vertically polarized. There is also a good deal of 6
meter FM during openings for when you are sick of the '59 goodbye' contacts.
In its current form, I don't believe the deviation is wide enough to sound
full on a decent 2 meter rig. One thing is for sure, the FM transmit quality
between my IC-271 and the Flex is astounding. If "proper shaping of the
audio" fixes this, I'll be a happy camper.

Re: [Flexradio] Voice Shaper 0.93 beta

[Bob McGwier]

Because it is not an open source product and even if it was we would 
really be in trouble if the license granted by Alex was not consistent 
with the GPL.


What Alex is proposing and it is a proposal I wholeheartedly agree with 
is providing the hooks to integrate it since we want to do that 
generically and enable such a thing as a matter of course by giving 
ourselves a description of the functionality of the add in and where its 
sink and source need to go.


We benefit from the outside work, work we have no time to do ourselves, 
and everyone benefits that wishes to use his fantastic work.


I think probably this discussion is better held in Flex Edge since it is 
about nonexistent (so pre-alpha ;-)  software.

FLEX cannot distribute it with PowerSDR, but we can and should test for
the presence of this dll and make use of it.  We can and will be doing
this a lot in the replacement code coming this year after PowerSDR 2.0

I am thinking we should offer several modes built into the GUI with the

Re: [Flexradio] Spur in PSK31 output even with no rf out into Dummyload.

[Bob McGwier]

I was going to say this perfectly demonstrates both the great power 
(sensitivity) of the panadapter and our greatest curse at the same time. 
 I was going to give my usual long winded commentary but I must admit 
that your 3 letter comment is right to the point.



There are design compromises in our resampler (which will be eliminated 
in an all new version of things later by using the arbitrary phase 
resampler which will have 120 dB noise floor and cost FEWER ticks by 
lots than the current one).  But VAC itself has a resampler or uses the 
WinBLOWS resampler (horrible) depending on the interface, driver, etc.



YO PEOPLE.  When you have 140 dB of dynamic range displayed in front of 
you as in our panadapter with standard settings,  get an idea that is 
FOURTEEN orders of magnitude in power, seven in voltage.  10^14 is a 
very large number and is huge in signal processing even if it is about 
the right amount when discussing next year's US government deficit spending.

If there is built in to the fldigi development and intent to allow for

You can run wireshark for windows and determine if data is being sent

Everyone who seriously uses the internet in this day and age of CONSTANT

Thinking that this might have something to do with my AV software,

with the internet connection showing T/R activity only when fldigi is

I have re-booted the machine; nothing changes. I am a bit concerned 
that I might have picked up a contaminated copy of fldigi; I 
downloaded this copy directly from the fldigi web site.


I would appreciate comments from anyone who sees through this

"the only people for me are the mad ones,
 the ones who are mad to live, mad to talk,
 mad to be saved, desirous of everything at
 the same time, the ones who never yawn or
 say a commonplace thing, but burn, burn, burn
 like fabulous yellow roman candles" Kerouac
