FreeDV on Smart SDR 1.4.11

  • Updated 4 years ago
The Waveform installer is available here:

http://www.flexradio.com/downloads/freedv_waveform_installer-msi/

I installed the file. A FDV red icon appeared in my desktop.



I clicked on File > Waveforms... inside the SmartSDR program. 

Inside of WaveformManager I clicked "Installed..."



This took me directly to the right folder in my system:



I selected the only file there, clicked OPEN and FDV was installed.

I can now selected FDV mode in the slice:



If I double click the FreeDV red icon in the Desktop this little window appears:



If I TX this is what appears on the radio screen. 



Not sure if it works I will stay in 14.236 and wait for any FreeDV activity.

Exciting times to own a Flex Radio! Thanks FRS Team!.

What does the waveform look like when you transmit with voice?

The desktop icon is to show and send the callsign / message text.  It is an "el cheapo" app that is largely crafted as a demonstrator for some enterprising coder that wants to code from an example.  It is not intended to be a polished application. You can type your call and a message in the box below and it will stream out with your data.  The callsign data is not error corrected so it will often get errors if your SNR isn't great.  Also the green bar is a reading from the SNR measurement inside the codec.

Can the data/message be read by all FDV users or just Flex folk?
Thanks for your clarifications on this new release in this thread and others. You have a talent for explaining complicated things so those not in the field can understand. You should write a book.

How much power should I use when running FDV?

The FDV mode shows up ok but when I click MOX, I don't see the carrier as you do. 
Clicking red icon, the little window doesn't show that strange text either. It is empty.

Just completed my first FreeDV QSO with Mel, K0PFX, in St Louis, MO (from Greenville, SC).  I was on 14236 KHz.  Ran about 45 watts.  He gave me a 10DB SNR (he was using a Flex 5000)..  Is there an SNR meter indicator in Smart SDR?.

Does the audio processor operate in FDV?  He indicated my audio was a little rough, and I was in the DX position on the processor.  Moved it to Normal.

Neat stuff.  Nice to have a new mode!

There is an SNR meter in the applet that installs.  You can click the red FreeDV icon and the green bar is the SNR.

I am not seeing a green bar, it is indicating as a blue bar and does not react to signals I have received.  SW loaded as normal, as I did it according to the instructions.

I can hear someone but I am probably not decoding correctly. It sounds like a robot !

OK, anything below a signal of 3 is squelched, signals of 5 or more come thru clearer.

I have tried to monitor a couple of slices in FDV and it seems that if I mute one it does actually mute. If I change it to a different mode the mute works. Is anyone else experiencing this?

Neat! I can hear various stations but cannot transmit ("No FreeDV slice." appears in the FreeDV window. I suspect there is something I forgot to do in DAX or something. :(

You must have the mode set to FDV in SmartSDR.  This is what the Windows applet looks for in the API.  Then you'd also have to have transmit enabled for the slice by pressing the TX button on the slice flag.

Done that, but still nothing. Will start a separate thread to avoid "hijacking" this one.

Just had 3 QSOs with FDV. 
Sounds a bit bassy.
Left channel only? Is that normal?
When the other guy drops below S5 you loose everything. Not much of a mode of you ask me. :*(
I guess it's ok for strong and steady signals.

Digital modes need good signals. They do not graciously degrade like analogue modes as the power drops, they drop off a cliff at some point as I believe is the case with all digital modes.

Ummmm...Yea but with keyboard type digital modes you loose a letter now and then and with Hellscriber maybe things get a bit fuzzy but with FDV it's like BLAM....You loose an entire sentence. I would be ok with maybe a QSB to a Mr. Roboto voice but seeing a nice signal on the screen and hearing nothing bugs me.

Just had my first three contacts.  Sounds good here.  Better than DSTAR in my view.  I noticed audio in only one speaker as well.  I also noticed you wont get a decode if you have FDV selected on more than one slice at the same time.  I had 40m FDV on one slice and 20m FDV  on the other.   No audio until I took one slice off FDV. 

Marginal signals decode the best using my Pixel RF 1B mag loop receive antenna.

Cal:  Thanks for the first FDV QSO on 40M a few minutes ago!  Great fun.  Tried to log the QSO via DXKeeper as DIGVOICE, but LOTW threw up on that.  You may see a weird SSB contact show up.  Hope to see you on FDV again.

Thanks to Flex for another neat new toy!  73, Tom

For some reason I only get audio out of the left speaker. The balance control is in the middle.

A couple of points that may help some having problem a getting started with FreeDV.

Error: "No FreeDV slice"

If you start the FreeDV app (from the red Icon on desktop) and the little window open up saying "No FreeDV slice" there a couple of things that can cause this:

1) - you do not have the slice set to the FDV mode. Change to the FDV mode and it should start working correctly.

2) - The FreeDV app requires network access, separate from SmartSDR. So your firewall could be blocking it.

In my case I'm use ESET Smart Security. Every time I install SmartSDR I have to switch to manual mode authorize it to connect to the network, before I see he radio in the list. The same thing is required for FreeDV to work.After this, a rule is written and it works every time.

I listened a bit on 14.236 and heard a few short parts of transmissions so far. I'm have a problem with strong S9 QRM which is no help..  will keep trying.

Ken, the (Windows) firewall was the culprit... disabled it and got rid of the error message. Now to get into the Firewall settings and fix it once and for all, and then go make some contacts (I hope...). :)

There are 2 frequencies for 40m. Being in G land I wondered which they were using.

You can chat to others logged into that page entering text in the black bar at the bottom. As well you can update your listing for the frequency you are monitoring or calling on.
