Gqrx 2.6 released

[Alexandru Csete]

Greetings,

I am happy to announce that Gqrx 2.6 has now been released and ready
for download. As promised, this release includes experimental binaries
for the Raspberry Pi 2 and 3.

Thanks to everybody who contributed to making this release happen!

http://gqrx.dk/download


New features:

- 1-2-5 scaling on FFT axis.
- Audio waterfall.
- Remember AGC settings between sessions.
- Right-click on FFT resets frequency zoom.
- Separate dB ranges for pandapter and waterfall.
- Raw I/Q mode.
- Portaudio support.
- Command line option to set Qt style (fusion, windows, …)
- Binary packages for Raspberry Pi 2 and 3.


Bugs fixed:

- Stuttering audio with Pulseaudio backend.
- Use system font on FFT plot (too small font on high res displays).
- Broken FUNcube Dongle Pro+ support on Mac OS X 10.11.4.
- Correct display of negative offsets between -1 and 0 kHz.
- Reset frequency digits below the one that is being changed.
- LNB LO could not be set from I/O configuration dialog.
- Update squelch level when switching between demodulators.
- Set correct filter range when loading bookmark.
- White area on waterfall.
- RFSpace Cloud-IQ support on Mac OS X, RPI binaries and in PPA.


Miscellaneous improvements:

- Input decimator performance.
- SDRPlay integration through SoapySDR.
- Only probe for devices when the program is started.
- Allow user to enter ALSA device name.
- Set default audio FFT range to -70…0 dB.
- Restore audio FFT dB scaling between sessions.


The download page and the Ubuntu PPA have already been updated with
the new source packages and binaries for the Raspberry Pi 2 and 3. Mac
OS X users will have to wait a few more days for and App bundle.

As mentioned in the release notes, we have fixed RFSpace Cloud-IQ
support in gr-osmosdr and Gqrx can now work reliably with the
Cloud-IQ. The patches are integrated into the Raspberry Pi binaries
but not yet in the Ubuntu PPA. I anticipate a PPA update during next
week that will include both the RFSpace fixes and some Airpsy
improvements.

I hope you will enjoy this new version of Gqrx and stay tuned for
exciting new developments in the embedded single board computer area
in the foreseeable future.

Let us know what you think!

Thank you so much for improving a product that gives me so much enjoyment.

The addition of the ARM based Raspberry PI 2 and 3 is an exciting new direction for Software defined radio enthusiasts.

I congratulate you on this excellent achievement and milestone.

Great

I did test this version . It is working fine . As now it supports IQ output . I have 2 questions :

- On windows SDR software, when outputting to IQ, sound is mutted allowed to listen to IQ result . Can we do the same with GQRX 2.6 ?

- Now that IQ is supported , how can we do to send IQ to telive TETRA decoder ? (using PACAT command line)

I did some tests no error but no result

I'm using this script

#!/bin/sh
export TETRA_HACK_PORT=7379
export TETRA_HACK_RXID=$1
ulimit -c unlimited
pacat --passthrough -v -d alsa_output.pci-0000_00_1b.0.analog-stereo |./osmo-tetra-sq5bpf/src/demod/python/simdemod2.py -o /dev/stdout | ./osmo-tetra-sq5bpf/src/float_to_bits /dev/stdin /dev/stdout | ./osmo-tetra-sq5bpf/src/tetra-rx /dev/stdin

Source code of telive :
https://github.com/sq5bpf/telive

That would be great because it could help us to monitor TETRA using Airspy or sdrplay correctly

Hi,

In gqrx raw I/Q is pretty much like stereo audio but without
demodulator. So, if you turn the volume down there will be no output.
I am considering adding an option for a secondary audio device that
would allow using one audio device for listening and another one as a
loopback device for piping to external apps.

I don't know much about this so I can't help much right now, but you
can try recording the raw IQ to audio wav file and replay it in your
pipeline outside gqrx to see if the captured IQ is OK. I haven't
tested much so there could be some bug.

With pulseaudio, there is an audio control, generally found on the desktop panel top right-hand side (may be elsewhere if you are not using the Unity desktop) in the form of the loudspeaker icon 🔊.

The lowest option on the control is labelled Sound Settings…

Within the Sound Settings panel is a tab labelled Applications. Using this tab, one can mute individual applications, such as GQRX.

However, you may find that JACK provides the flexibility of audio routing that you are looking for, but it will be a steep learning curve. [I have managed without using it in the past, but for applications such as fldigi JACK is quite attractive. YMMV]

HTH,

Robin, G8DQX

I tried using Gqrx for the first time (new SDR) and the app crashes on launch (OS X Sierra). Can post more of the console log if that would help.

Hi Erik,

I have built it on El Capitain and I guess it is not compatible with
the new version. You are welcome to post more info but I suspect I
will have to rebuild the whole toolchain for Sierra and I don't have
time for it right now, sorry.

Alex Gqrx runs OK! on OS X Sierra!

The only issue I can find is a small issues with frezzing whaterfall when shifting mode and frequency fast, typical when using the scanning scrips.
I had the same issues with the 2.5.3 version on my Mac with El Captain and Sierra.
I don't belive that the whaterfall issue is coused by gqrx. Addressing a virtual audio interface made by "Rogue Amoeba Loopback" makes gqrx run very good, not perfect but very good. This Indicates to me that something happens in the Apple audio interfaces that is behind the waterfall problems i experience.
I have decreesed the FFT size from 8 something to 4 something and the rate so that I dont have any overlap. I dont remember as Im at my work now.

Sorry for my English.

Yes it seems to work fine on my MacBook Pro. The crash I had is on my Hackintosh- not clear if that's why (never had an issue with other apps). I will try to investigate it more. 

Thanks,

Erik.

Whether that's the reason I can't tell, but you should definitely
include that info in future problem reports as it is is a significant
deviation from a "standard mac" setup ;-)

Bonjour,
J'ai installé sur mon raspberry pi3 model b la version Gqrx 2.6 .
J'utilise le Funcube pro plus  et je constate que lors d'écoute sur le 14.122Mhz je dois utiliser le mode LSB pour pour que cela soit   compréhensible .
Je pense que le mode USB serait plus logique ?
Cordialement.
F1HCN

[Robin Gape]

1) is Swap I/Q selected? (Would give this effect)?

2) Is there the same problem on an x86 PC or laptop? (To check the FCDPP)

3) Is there the same problem on other frequencies—does 40m have USB signals rather than LSB, for example?

4) Does the passband tune backwards? (may be easiest to see with another RX, or on MW/MO)

5) Sometimes the IQ balance gets confused, overcompensates, and swaps I&Q. Try deselecting IQ balance. If that cures the problem, then IQ balance may safely be selected again. This problem seems to occur when there are only a few weak signals in the FDCPP passband. (In my case, the local 1296MHz beacon.)

HTH, 73

[Richard Ferryman]

Thank you!  At last I have the ability to use the Funcube Pro+ on a Raspberry Pi 2.
Now I have a good reason to buy a RPi 3.  Install was straight forward even for my old brain and it runs surprisingly well.  I feel like I have received an early Chritmas present :-)

[Alexandru Csete]

Thanks for the feedback Dick!
I did get some help with testing before the release so I could try a
few iterations of packaging and installation notes :)

thanks very much, Gqrx on raspberry pi3 works nice,i had a question about source for raspberry pi3?
i want to build source on raspberry pi 3 myself. older source on github can be built for raspberry pi3??
best regards stackprogramer

So the Ubuntu PPAs don't (today) fully support yakkety... This means it can't be installed on Ubuntu 16.10... 

And the version on the official Ubuntu repository version (2.5.3) is broken on Ubuntu 16.10 (libgnuradio-blocks segfaults)...

So kind of a bummer. :(

Hi Gilles,

Please see the other threads regarding the problems on 16.10.

The crash occurs in a library so there is nothing to fix in gqrx and
it wouldn't help to have 2.6 in a PPA - it would still crash. We are
trying to come up with a workaround and then we will update the PPAs
to provide the working versions, so please be patient.

Hi David,

There are a few libraries you have to install before you can run gqrx
on the Raspberry Pi. Please read the included readme file or the
instructions on the download page:
