Re: fldigi 3.22.08, portaudio, signalink usb, raspberry pi 2



The configure script is supposed to autodetect pulseaudio and build accordingly, but you can explicitly request it by giving the configure script the option "--with-pulseaudio" It's curious that it lets you use portaudio even though configure is building fldigi without it.

Thanks for the response guys. I have the latest version of libportaudio-dev. I tried to configure 3.22.08 again just incase I installed that after the fact. Is there a switch that needs to be set to configure with portaudio? I notice at the end when I run ./configure it lists a summary and under build options it shows
Sndfile...no
oss ...yes
Portaudio...no
Pulseaudio...no
Flxlmrc...no
Hamlib...yes
As previously stated I am able to select portaudio in version 3.21.48.

Thanks

HI,
You need this: https://packages.debian.org/wheezy/libportaudio-dev .  That is the development package for portaudio.  Fldigi needs this when you are building from source.

Linpac 0.21 (AX.25 packet radio application) posted




Hello Everyone,

This is just a heads up that I have posted Linpac 0.21:  https://sourceforge.net/projects/linpac/


What is Linpac?

LinPac is an Ncurses based AX.25 packet radio terminal for use with Linux's native AX.25 stack.  It mimics many of the feature packed HOST-MODE programs that used to exist for Dos (PkGold, etc) but with any TNC running in KISS mode. It allows wide configuration and easy addition of new functions and special functions needed by the user. It's intended for keyboard-to-keyboard use but also supports receiving basic PBBS messages, local Converse-link chat rooms, basic node commands like mheard and making outgoing connections, etc.

The aim was to minimize the amount of 'hard coded' functions and create a complete set of applications that can be easily expanded and/or completely reconfigured via a simple macro language.  There is also a developing GUI version (1.x branch) that provides either a Java Swing GUI or the familiar Ncurses UI.


Changes since 0.20:
--
Memory cleanups
Fixed Debian based ncurses package dependency
Added a cron-able script that can send email and SMS notifications when you get a new Linpac message
Added a script to start linpac via screen for being able to detach and re-attach to the session from anywhere
Added some Ncurses fixes for spurious "x"'s showed up instead of vertical lines
Added lots of things to the linpac-todo.txt  (we'd love to get more C developers to help out if you have some time)
--

There aren't any binaries posted at the moment but I can email Centos6 RPMs and Raspian(wheezy) .debs if requested.  Everyone else will need to read the README file included in the sources on how to install the required dependencies and build the package yourself.  It's not hard and is quite fast.  Once installed, Linpac will NOT work without a properly configured Linux AX.25 stack.  There are many resources out on the Internet on how to do this and I can help out as well if requested.

Multiple sound cards and FLDigi

I'm running Mint 13LTS Mate 32 bit and I have 3 sound devices installed.

I followed the tip in the FLDigi manual and added 
/etc/modprobe.d/alsa-options

# Set preferred order of the sound cards
options snd-CS46xx index=0
options snd-CODEC index=1
options snd-SB index=2
options snd-HDMI index=3

The problem is my sound cards are not in that order.  Adjusting the web 
browser volume seems
to change the TX level on FLDigi even though it is not using the same 
sound card. Pulse audio doesn't
seem very user friendly.

mike <at> mike-GA-MA785GM-US2H ~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****

I thought it was working at one time but it doesn't appear to be now. 
Any suggestions would be appreciated. I'm a newbie so I'll need detail.

Extending battery life on MacBook Pro using FLDIGI



I am using the latest FLDIGI on a MacBook Pro Retina (bought late 2014) running Mavericks.


When I field operate on PSK with my IC-7200, the limiting factor for operating times is the laptop, which chews through the battery quite quickly while running FLDIGI. Only my copy of Cinema 4D can exceed that.


The activity monitor shows it running at over 22%.


I've used the 'slow CPU' option which appears to have some effect (down to about 17%).


Are there any bare bones configuration settings that might bring that CPU use down even further? The command line options don't seem to offer anything obvious.an>

Hi.

Some digimodes though using signals that spread over a few 100Hz to several 
kHz, actually only transmit one clean "tone" at any one time.   So they can be 
suitable for Class C PA's etc.    So you could put a multi kW Class C PA after a 
low power SSB TX in that case.   The SSB TX is only a frequency changer in 
effect.

RTTY, CW are the obvious modes...

Other modes that involve PSK type signals, single or multiple "tones" at any one 
instant in time, then yes they do need ultra linear signal paths in the TX chain, 
as they have a very significant amplitude component to their signals.

For long distance paths subject to multipath, selective fading and so on...

If you look at:-
http://en.wikipedia.org/wiki/Olivia_MFSK

That is listed as being very good for the sort of propogation troubles of interest.

It realy does work very well indeed, and of course is a standard mode included 
within Fldigi.   On 60m (5MHz) you can hold onto a QSO when you can't even 
hear the signal, or even in the presence of some quite severe QRM.

Though it only transmits one tone at any one time, they are amplitude shaped to 
reduce sideband artifacts due to the rapid sequence of carrier frequency 
changes, so will also have some significant amplitude linearity needs, but as only 
one "tone or carrier" is used at any one time, you can "crank it up a bit" when 
needed, without unduly splattering all over the spectral neighbours, unlike when 
you try that with PSK!....

Enjoy!..

Aw: Re: Best non-RTTY Digi for multi-path, QRM, polar flutter?



This depends on how the tones are switched... In DomEx e.g. the tone switching has been made 
soft enough to allow using a class C amp. In this case there is hardly any amplitude variation
when going from one tone to the next.

I don't know how to amplify two carriers with a class C amplifier without extreme distortion.  I only know how to do it with tones and linear amplification.

All the transmission types using audio tones fed to SSB input must use a linear amplifier.

Or am I forgetting something again?  I do that these days.

Hi David,
 
DominoEX, RTTY, and other (M)FSK based modes can increase their power without suffering from the fuzzy distorted nature of PSK :)
 
This means DominoEX (and all other MFSK-based modes) can be used with "RTTY type" high-power RF amplifiers. Class A, AB, or C. 
 
For MFSK-based signals, the distortion incurred does not affect the data. For PSK signals, this non-linear amplification can destroy the data. Not because it's a single carrier, just because the type of distortion doesn't affect that type of modulation much. Same for CW and Hellscreiber. The distortion goes unnoticed.

John,

So you can use DominoEX8 and increase power to increase range because  it is only a single carrier like RTTY, Throb, and keyed CW?

I think Hellschriber is also a single carrier too.

In other words the signal does not get wide and fuzzy when you increase power like psk does?

Hi to all :)
 
Wanted to chime-in after reading through the discussion thread. This is interesting stuff to me. 
 
Given the low-to-no delay requirements of RTTY contesting, it is pretty much impossible to use forward error correction to add robustness. :-/
 
That said; ZL1BPU did create the DominoEX modes to address the HF channel issues being raised in this discussion thread, including the contesting requirement of having no turnaround delay. 
 
Using DominoEX8 (available in fldigi) will give comparable speed to RTTY 45, has about the same bandwidth, and is far more robust on a poor channel.
Also, this mode can be used with non-linear amplifiers, just like RTTY. 
 
For an in depth read, there is a great MFSK paper ZL1BPU wrote  available at :  
 
Also see the DominoEX specific page at 
 
Far as I know, nobody's compared RTTY and DominoEX8 on-air to get numbers for comparison. 
It definitely has the potential to be an RTTY successor, if that is what is being looked for.

I suppose another factor in this question is that RTTY is almost never used
conversationally anymore; it it almost exclusively used for contests and DX
chasing.  And in those activities the ability to out-shout your opponents is
important; hence you want all the power you can get.  In my opinion
RTTY remains popular for contests and DX because it offers very quick
turnaround and acceptable accuracy.  In those activities speed of making
a contact is all-important.  You don't need a lot of accuracy because you
already know the call sign of the station you are calling, and you know the
RST will be 599, so if what you see on the screen looks like what you want
it to you call it a good contact.
