Re: [Flexradio] Digital modes not working correctly anymore

[Steve Sterling]

How about the audio level into your digital app?  There is a "sweet 
spot" between the RF gain (AGC-T), and AF gain for good decoding. 
Generally quite low AGC-T at least with FlDigi I use.

"When using say psk or rtty etc everything works fine if I use usb/lsb and not

Your digital mode program does not talk native PowerSDR CAT, so it is confused 
about the modes DIGU and DIGL.  In the CAT setup, check the box that says 
DIGIL/U returns LSB/USB.  Programs like FLdigi speak PowerSDR CAT fluently.

"When using the DIG modes on PowerSDR I have a terribly wait before it actually 
sends after keying and after it finishes sending a long wait before it returns 
to receive.."

You are using HRD and DM780 and there are known problems with delayed PTT 
operations.  It is specific to these programs.  Other digi mode programs do not 
exhibit this delay.

Except when there's no alternative ;-)

Some of the modes will suffer worse than others. One thing to keep in mind
is that many of the soundcard digital programs are built around
voice-channel bandwidth and common consumer-grade soundcards. You have to
resample the...ahem...high-quality SDR audio anyhow. Even a weak-signal
program like WSJT is doing some serious mangling to the signal in software
on the radio side of the software codec.

As it is right now, almost no common digimode program is really set up to
take advantage of what all-SDR can provide. The digital paths are there for
convenience, mostly, not performance.

Under Linux and OS X this is easy since the "modern" audio subsystems are
designed with full-duplex patching among audio apps in mind.

However, it *does* make some sense ultimately to put codecs into the SDR
DSP, for a variety of reasons. But this transposes the problem to a
different area. On the application side of the codecs, the data will be
bits, not samples. What's the transport yoga for these bits? If they
represent varicode, where does the corresponding binary codec live?
Furthermore they could be soft and not hard bits. Is the idea to put every
variety of Viterbi decoder into the SDR? If not, what's the protocol?

None of these questions has even begun to be asked yet, much less addressed,
and it's lunacy to plunge ahead with a one-off solution based on our own
idiosyncratic needs.

It's a further safe bet that the existing digimode programs are far, far
away from being restructured to handle binary data I/O rather than digitized
audio, if indeed they can be restructured at all. Very few of the ones we've
been able to examine at the source level (far too few of them BTW, since so
many of the authors lock up the source) are designed for the kind of
concurrency that would make that job palatable.

Also BTW, these are exactly the issues that arise in building a systematic
solution for digital voice, but in spades, since in that arena it will be
almost essential to have a fairly tight feedback loop between the codecs and
the DSP, irrespective of what the audio payload might be. The current
generation of digimode programs, by and large, isn't up to that job in
particular.

Well, not quite. I try to stay away from Windows wherever possible so  
all my preferred digital mode programs run on Linux and MacOS.  
Regardless, I understand the reality.

Thank you (and everyone else) for the responses, both here and in

Re: [Flexradio] digital modes

[Ray, K9DUR]

Brian,

Although I believe there was some initial intent to include the digital
modes in PowerSDR, it was decided not to re-invent the wheel.  There are so
many excellent digital mode programs out there, it was better to focus the
limited programming resources on improving PowerSDR.

Now, to answer your real question.  There is a 3rd party program called
Virtual Audio Cable (VAC) which creates audio "cables" in software.  These
virtual cables are used to pipe the audio between PowerSDR & a digital mode
program such as MixW or DM780.  Unfortunately VAC is not free, but it is
reasonably priced at $30.

There are several articles in the Knowledge Base on the FlexRadio website
that discuss the use of VAC with PowerSDR & digital mode programs.  The
following article gives step-by-step instructions on how to set up VAC.  The
article is a little dated, but is still a good starting point.

 http://support.flex-radio.com/Downloads.aspx?id=117

It is possible to download a free trial version of VAC.  However, the trial
version inserts the word "TRIAL" into the audio stream every few seconds,
making it unusable for on-the-air tests.  Once you register the product, you
can download a version without that annoying message.

Re: [Flexradio] digital modes

[Tim Ellison]

PowerSDR is not a digital mode program.  There are no current plans to make it 
one since there are sooo many good programs available to operate digital 
modes.  FLEXability is PowerSDR's first name.  There is no need to reinvent the 
wheel.

"So, does one just pipe the audio bitstream to another program to do the 
decoding?"

That is one way, and IMHO the preferred way to do it.  You can also cobble 
together an external audio interface to a sound card in a computer in the 
traditional way you connect a transceiver to a computer for digital mode 
operation.

In the first case, a third party program called VAC is used to create a virtual 
audio cable (VAC) between PowerSDR and the digital mode sound card program.  In 
this configuration the AF between the two programs is kept entirely in the 
digital domain eliminating any noise or distortion introduced in the multiple 
A/D and D/A conversions.

With VAC, PowerSDR "looks" like a soundcard to the digital mode program.

See the following KB articles for more information:
FAQ: What is VAC and What Does It Do? 
(http://kb.flex-radio.com/article.aspx?id=10475)
HOWTO: How to Setup Virtual Audio Cable (VAC) 4.0x with PowerSDR 
(http://kb.flex-radio.com/article.aspx?id=10218)

When you combine VAC with a virtual com port (vCom or Com0Com) to provide CAT 
support to the digital mode program, then you have a fully operational digital 
mode station.

This will work for all digital mode programs except for the ones that require a 
specific sound card to work.  In these cases, you will need to cobble together 
and external audio interface using the FLEX-5000 line in/line out (RCA 
connectors).

This is probably a silly question but I am wondering how one runs
various digital modes with the Flex5000. I assumed that PowerSDR would
provide the requisite codecs for various modes; e.g. psk31, mfsk,
hellschreiber, etc.; but I didn't see it in the description.

So, does one just pipe the audio bitstream to another program to do
the decoding?

Joe,  how do you save the receive filter?  When I save a new profile,
or one I change, it will indeed save the tx filter, but not the rx
filter.  Is this maybe something new above svn 573?  That's what I'm

Re: [Flexradio] Digital modes questions

[Joe - AB1DO]

Paul,

you may also want to take a look at the PowerSDR manual version 1.6.2, 
specifically the Digital Mode Operation section of chapter 10: Operations, 
which starts on page 131. This section includes updated VAC installation 
instructions, based on the document originally written by N4HY as well as 
up-to-date step by step installation instructions of N8VB's VCom virtual com 
port utility. MixW is used as an example of how to set up a third party 
program to operate with PowerSDR using VAC and VCom.

There are 2 notes on page 133 which detail what the buttons DIGU, DIGL and 
DRM do.

Also, there is a hint that describes the  2 ways of using the filters of 
PowerSDR and MixW (eg). The first is to set a wideband receive filter in 
PowerSDR and use the filtering capabilities of MixW to isolate the signal of 
interest. (This is akin to how MixW operates with most hardware rigs.) To 
transmit successfully this way, you do indeed need to make sure that your 
PowerSDR transmit filter matches the receive filter settings or you may not 
have any RF out at the filter's edges as Jim describes.

Secondly, you can use the (superior) PowerSDR narrow band filter 
capabilities to home in on the signal of interest. In MixW you will then 
only see 1 single signal and the rest of MixW's waterfall display will be 
black - quite an interesting sight. In this mode you do all your tuning with 
PowerSDR. Through VCom, MixW will track PowerSDR's VFO frequency. If you 
also set your transmit filter just wide enough to transmit the digital 
signal without distortion, chances are you will achieve better sideband 
suppression than otherwise available.

You can save the desired PowerSDR receive/transmit filter settings (for 
various digital modes and wide/narrow filter settings as desired, as well as 
transmit power, etc ) as a Profile in PowerSDR's setup>transmit form. That 
way, the settings are easily available each time you wish to operate a 
specific digital mode using either wide or narrow PowerSDR filter settings.

Finally, the trial version of VAC periodically injects an announcement (of 
the VAC version, if I'm not mistaken), which will distort your 
received/transmitted signal. To get rid of this, you will need to purchase 
VAC.

Hope this helps,
73 de Joe - AB1DO

Paul,
I am pretty new at this also, but will share my findings and embarassing
"foo paws" (red neck for faux pais).
I am running MixW 2.17 and PowerSDR 1.6.2. Power SDR is set up exactly 
like
the manual. I have worked rtty, cw, and BPSK31 with very good results
considering I have only a 40M off center fed dipole in the attic.
For the foo paws, I would make a contact and everything would work 
fine. I
would then tune up the band and all of the sudden when I would attempt the
contact, NO RF out!!! Took a while for me to figure out what was happening
including a couple of reloads of MixW. Actually the problem was a short
between the ears. With PowerSDR you can LOOK at a wide segment of the
spectrum, 6.0kHz. BUT the transmit filter is not that wide so when I
moved up the band far 'nuff, MixW did its thing to put out the audio, but it
was outside the transmit filter band pass.
VAC  Took this old bird a few moments to get that down but when I
followed the directions and mentally tied it all together, I love it.
Virtual Serial Ports. A dream come true. I just don't know why I did not
think of that years ago. To think of all those null modem cables I
built.
For me, the SDR-1000 comes into its own on digital. And yes, I think the
digital modes DIGU/DIGL are there to switch in the VAC. Actually I leave VAC
in all the time because my other favorite mode is CW, but being somewhat CW
challenged I use CWGet to boost my CW cognizance. .
There are a number of packet programs out there that do generate the 
packet
doodles in software. I am suprised that MixW does not. I have not tried that
one so really cannot speak very well to that issue.
I found, that for me at least, it sorta took a few days to get 
everything
settled. I made a lot of backup copies of the database, so I could get back
to point B from point Z, and even resorted to a Windows RESTORE at one
point. But the effort has been fruitful. The system is quite stable at this

I have even been able to switch into the 1.6.3 SVN whatever and just

Re: [Flexradio] Digital modes questions

[Tim Ellison]

Paul,

It really isn't off topic. Asking how to replace the alternator on a 74
Fiat - now that is off topic.

First off, to get to the root of your issues requires a bit more detail
info.  In this case specifically what version of VAC are you using?  4.x
or 3.x?  3.12 is still the best version to use.  4.x has some issues.

One of the problems you may be having is that the trial version
periodically transmits the phrase "Trial version" (or something like
that) which is injected into the audio stream and destroys most digital
reception.

Second, it sounds like you are close.  I would focus on a simple digital
mode like PSK31 and when you have that down solid, then RX and TX of
other digital soundcard modes will be a snap.

Third, DigiU mode is upper side band, but there is no processing done on
the signal at all except of AGC.  It bypasses compression, the EQ and
things like that which would adversely effect the TX of a digital mode
signal.  You have to engage VAC in automatic mode to get it to come on
"automatically" when in a digital mode (digiU, digiL and DRM).

Subject: [Flexradio] Digital modes questions

Sort of off topic, but you folks collectively know everything, perhaps
you can help.

I followed the flex document "powersdr_vac_operation.pdf" and have been
able to receive a few digital modes for the first time (using mixw).
Since I have almost no idea what the spectrum or waterfall looks like
for any mode it's taken
2 sessions to start to receive anything. I have to look for any signal
in the rtty and packet bands and start guessing the mode and settings.
There is almost nothing on the air generally. So far:

Packet: got some callsigns, then I messed up the settings or something.
Couldn't get anything else.

RTTY: achieved my first reception ever. It was the "ratts net" in the
western states. 

Even though I downloaded the trial version of vac I was able to send
RTTY test transmissions. WIth 1W I'm not going to do much.

BPSK31: listened in on a qso about 300 mi away, they were running very
low power I think. Many errors.

PACTOR: picked up a local transmission here in Boise. I read that an
external TNC is required to send pactor. Why is that? Why wouldn't
pactor be implemented fully in software?

It takes hours to do anything, there are almost no signals here. I have
been able to do everything with the trial version of vac, what are it's
_limitations_?

Is the sdr1000 digu mode the same as usb, except it controls the auto
enable vac?
This is only a guess, I should rtm.

Re: [Flexradio] Digital Modes anomalies

[FlexRadio - Eric]

The transition issues were affected by the recent changes to improve CW.
We're working to smooth out the rough edges.  I was unable to recreate any
problems with VAC Auto Enable.

I sure have in digiU mode.  There was a bug on Bug Track, but it seems
to be gone.  The audio spike sounds like a combination of a pop and a
chirp.  The funny thing is if you listen to the TX signal on another
receiver, the audio artifact is not in the transmitted audio.

GM,

Using SDR v 1.6.2 SVN 556 or Jeff Anderson's June 23 release and
operating DIGU/L mode with MixW, in Setup/VAC I need to check Enable
VAC.  Auto enable doesn't work.

When going from transmit to receive, there is a large audio spike of the
transmitted audio sent to the headphones/speaker.  Using FireBox (no
firmware mods).

Anyone else notice these anomalies?

73, Chas W1CG

Re: [Flexradio] Digital modes perfect but no ssb?

[Ross]

OOOps thanks, that does make a heck of a lot of difference,
but shouldn't that be an automatic feature of the software, when in ssb, 
that VAC is shut off?
for example while working 3d2ba on Olivia, (he is literally  just across a 
bit of ocean)

we often swap to ssb to make any quick comments

Advice please,
I am using preview 5 and the digital modes work perfectly, using vcom ,

I went back to check USB and unfortunately nothing. No power output and 
nothing showing on the panadaptor while speaking.

Any one any ideas as to what I have done wrong..
Thanks

 Did you shut off VAC when you went to SSB?

The digital mode button is on the list.  That's all I can say for now.

Bob, I've long thought the easiest and best way to do this is to have a 
"RTTY" or "Digital" check box, perhaps near the band buttons.


This would fairly easily accommodate all of what you are talking about. 
The idea would be, if you are using a 3rd party program and they put it 
in SSB (USB _or_ LSB) for digital modes, then the CAT commands would 
work as those programs expect.  

But, the check box could enable all sorts of other useful things, things 
you as the user would want to enable:   1) special filtering, or at 
least alternate filter button selection, 2) turning off all the various 
compression. etc. for SSB so digital has its own less modified shape, 3) 
Accepting a few other sources than the paddles for CW (c.f. the old 
keyer).  And so on.  

All of which would be enabled by the "digital" check box that would, in 
effect, create a set of alternate settings.  Thus, all 3rd party 
software and hardware could be accommodated in that manner.

Now that the VAC is implemented, how long will it be before the digital
modes are enabled?  I think Bob mentioned the code has been ready.

Recommend when you do, that when clicking on RTTY or PSK (one for SSTV too?)
that the VAC is automatically enabled.  When click any other mode it should
automatically be disabled.

I know FSK is not ready yet, but would still be nice to have the digial
modes in AFSK for now.
