Hi all,
David Rowe has the C++ sauce code available for his new mode 700D on github.
Mark VK5QI and I just made a QSO using it on 7177KHz LSB This evening 9pm Sunday
On Linux
svn co
https://svn.code.sf.net/p/freetel/code/codec2-dev
mkdir build_linux; cd build_linux; cmake ../ ; make; sudo make install
and the GUI app
svn co
https://svn.code.sf.net/p/freetel/code/freedv-dev
echo '========== Build instructions ========
edit CMakeLists.txt
modify set(USE_STATIC_CODEC2 FALSE CACHE BOOL
modify set(USE_STATIC_SPEEXDSP FALSE CACHE BOOL
search WXRC "" => "wxrc-3.0" and line before "" => "wx-config-3.0"
mkdir build_linux; cd build_linux; cmake ../ ; make

It's been a very long time since I could be bothered **** around with all the linux build palaver but these lines look like they have unterminated expressions:
modify set(USE_STATIC_CODEC2 FALSE CACHE BOOL
modify set(USE_STATIC_SPEEXDSP FALSE CACHE BOOL
Should they have terminating brackets somewhere?

I help the developer by downloading, compiling and running the code.
This is how I help the developer.
The notes above are "notes to self" and I expect you the reader to interpret them that way.
The Codec2/FreeDV project is quite important to us hams.
Digital HF communications carrying voice, real time, at low signal strengths, is coming and we want to be there.
FreeDV gives us semi-secure HF voice comms method NOW.
Who will be the first to do EME with this mode?

So then answer the question...
Are there missing terminators in those two lines?
I've played with a lot of scripting over the years and they look wrong, but I have no recent knowledge to know. I ask in case someone finds the thread and wants to use the scripts.
If you are one of those who think that being an OS snob is cool and important, good on you.
Me? After decades playing with machines starting with S100 bus jobs onto IBM PC (you know, before the 8088) right through to performance testing massive scale virtual environments I am a bit OS agnostic. Frankly I dislike them all.

Hi all,
For you Windows guys, David Rowe has made a ZIP file available, as pre-release.
An Installer package will be available later.

Hey David,
Thanks - it might help someone down the track.
Besides, you can take the boy out of test engineering; but you can't take the test engineering out of the boy.

Hi all,
Now I'm back from Croatia, a 12 day holiday trip, an update:
My "parrot" repeater on 7177 has been running 24x7 for two months now
with signals received on Sunday mornings from VK3 and VK5 but nobody
has yet triggered a "repeat". (except Hil VK2AZ 5km away)
Have a look at Codan's website and see their use of TWELP 600 digital mode.
We hams can be at the cutting edge of this Digital "revolution".
As you know, HF is "fickle" but offers long distance communications to a Skip Zone.
If we place a repeater in this Skip Zone, stations in a wide area can communicate via
this repeater. Perhaps a repeater in Central Australia (Alice Springs or Broken Hill)
could service all Australia.
Any thoughts?
Frequencies and times:
7177 here in Emu Plains is just not working. Do we have an 80m frequency for a night time net?
Should I move to 20m, 14236 in the daytime?
I'll have to do this manually, but being retired, not too much problem.

Summer is over. After three months on 20m, I've gone back to:
7177 KHz LSB is now the parrot repeater 24x7

Is the repeater only for parrots? If so, it should be well used, the old saying says: "birds of a feather flock together"

I'll ignore the parrot comments...
A stand alone Codec2 encode and decode box.
I've downloaded "SmallDV" from:
http://www.kk5jy.net/smalldv-v1/
and compiled it up on a Banana Pi M2 Berry and showed the box
at Wyong. Any Pi will do and a good USB audio dongle.
I've tested these USB thingies:
Creative Sound Blaster Play! 3................available worldwide
VOLANS chipset: ASMedia HS100-B.......who knows

My local radio club (AREG), have organised a FreeDV QSO Party for April

More progress with SmallDV sourcecode.
With a stereo sound card, one can use left in and left out for RX
and Right mic and Right out for Tx. Thus not needing a relay or quad bi-lateral switch.
Source on

FDVcoreStereo.tgz
Tested with: Creative Sound Blaster Play! 3
Why this device, available WORLD WIDE.
