FLDIGI hamradio digital modem decoder/encoder
 

Hi friends!
Imagine that while listening to your ham radio receiver you find a digital transmission and you would know what they are saying.... but you don't have a pc....
WRONG!!! You have your little dear N900!! :D:D

Oh yeah... i was forgetting that selecting the portaudio output device you could also write some text and encode it to obtain an encoded flux reproduced from the speaker of your N900. (so you can also transmit that text!!)

UPDATED!
All the packages are know available into extras-devel with proper optification to save your root fs space.

You can install:
fltk 1.3.2, hamlib 1.2.15.3 and fldigi 3.21.82.

Fldigi already contains the script to fix the font size and i suggest you to chose portaudio to record from the microphone the audio of your receiver.

Enjoy!

----------------------------------------------------------------------------------
Old setup:
(please use repo's packages)
Here you can find FLDIGI 3.21.76

So unzip, copy all the tar.gz in /opt/ , unpack them
and run /opt/fldigi/bin/fldigi

If you find some issue, try
ldd /opt/fldigi/bin/fldigi

and verify to have all the required libs.
(maybe a little boring process... )

To fix the hamlib dependency problem:

ln -s /opt/hamlib/lib/hamlib /usr/lib/hamlib
ln -s /opt/hamlib/lib/libhamlib++.so.2.0.16 /usr/lib/libhamlib++.so.2.0.16
ln -s /opt/hamlib/lib/libhamlib.so.2.0.16 /usr/lib/libhamlib.so.2.0.16
ln -s /usr/lib/libhamlib.so.2.0.16 /usr/lib/libhamlib.so
ln -s /usr/lib/libhamlib.so.2.0.16 /usr/lib/libhamlib.so.2
ln -s /usr/lib/libhamlib++.so.2.0.16 /usr/lib/libhamlib++.so
ln -s /usr/lib/libhamlib++.so.2.0.16 /usr/lib/libhamlib++.so.2

As suggested by the developer w1hkj, to increase the font size, run fldigi in this way:
/opt/fldigi/bin/fldigi --font sans:16


At this time, the only issue that i have is that the gtk theme does not work well and you must select the plastic theme.

Fldigi 3.21.76 pack:

Fldigi 3.21.39 pack:
(containing: fldigi_3.21.39_N900_Xes_ftk130.tar.gz fltk_1.3.0_N900_Xes.tar.gz hamlib_1.2.15_N900_Xes.tar.gz libsamplerate_0.1.8_N900_Xes.tar.gz)

Awesome! I will check this out tonight. Thanks!

Re: FLDIGI hamradio digital modem decoder/encoder
 

Thanks for the good work.
However, $: /opt/fldigi/bin/fldigi gets the following error: "./fldigi: error while loading shared libraries: libhamlib.so.2: cannot open shared object file".
$: ldd fldigi shows libhamlib.so.2 not found. However, it exists at /opt/hamlib/lib/libhamlib.so.2.
How should that be fixed?

Re: FLDIGI hamradio digital modem decoder/encoder
 

I added /opt/hamlib/lib to /etc/ld.so.conf and ran $: ldconfig as root. fldigi would then start. Don't have audio figured out yet.

Re: FLDIGI hamradio digital modem decoder/encoder
 

Yes! You are right.... i forgot to mention that there is some issue building fldigi through hamlib libs installed in /opt...

So, the solution is to make some symbolic link in /usr/lib:

ln -s /opt/hamlib/lib/hamlib /usr/lib/hamlib
ln -s /opt/hamlib/lib/libhamlib++.so.2.0.16 /usr/lib/libhamlib++.so.2.0.16
ln -s /opt/hamlib/lib/libhamlib.so.2.0.16 /usr/lib/libhamlib.so.2.0.16
ln -s /usr/lib/libhamlib.so.2.0.16 /usr/lib/libhamlib.so
ln -s /usr/lib/libhamlib.so.2.0.16 /usr/lib/libhamlib.so.2
ln -s /usr/lib/libhamlib++.so.2.0.16 /usr/lib/libhamlib++.so
ln -s /usr/lib/libhamlib++.so.2.0.16 /usr/lib/libhamlib++.so.2


Sorry but i suppose there is some bug into the configure process of fldigi and until now i can't address this problem.

PS.
added fix to the first post

Re: FLDIGI hamradio digital modem decoder/encoder
 

Looking at fldigi settings, try changing the audio input from portaudio to pulseaudio.
(both should work, but you are supposed to have all the libs)

Re: FLDIGI hamradio digital modem decoder/encoder
 

The audio is working. Cockpit error on fldigi squelch. Thanks for the excellent work. I'll continue checking out the N900 fldigi. Is there any way to zoom? Menu selections are pretty small.

Until now i think that the fullscreen trick is the only way to have a bigger window.
Fonts are taken from the fltk theme... i'm still trying to customize it.

Re: FLDIGI hamradio digital modem decoder/encoder
 

To add fldigi to the task launcher, I created the file fldigi.desktop in /usr/share/applications/hildon.

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Name=fldigi
Exec=/opt/fldigi/bin/fldigi --font sans:16
Icon=fldigi
StartupWMClass=
X-Window-Icon=fldigi
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable
Terminal=false

Then copy /opt/fldigi/share/pixmaps/fldigi.xpm to /opt/share/pixmaps/ or set up a link.

fldigi should show up in the list of apps.
(post edited to add proper icon and increased font size)

Re: FLDIGI hamradio digital modem decoder/encoder
 

Just added on the first post a tip to run fldigi with a different font..
