Hi,

Apparently airspy package from the raspbian repository is not enough / too old (??).

Thank you for the solution!

Regards,
O.

Unable to run SpyServer on Raspberry Pi #spyserver

Olgierd Pilarczyk
 

Hi,

I try to run the latest version of SpyServer on Raspberry Pi 3 with Raspbian, but get the following error:

pi@raspberrypi:~/spyserver $ ./spyserver 
SPY Server v2.0.1629 - http://airspy.com
Reading the configuration file: spyserver.config
Unable to load user mode driver for 'AirspyOne'
Closed all connections and released the device
*** Error in `./spyserver': free(): invalid pointer: 0x7ed6e35c ***
Aborted
Raspi runs quite fresh raspbian (Linux raspberrypi 4.9.41-v7+ #1023 SMP Tue Aug 8 16:00:15 BST 2017 armv7l GNU/Linux), installed airspy and libairspy0 packages.

Any ideas? :-)

Regards,
Olgierd SQ3SWF

Re: squelch debate

Leif Asbrink
 

Hi All,

Syllabic squelch is the only good HF squelch.
I think it has been patented by some firms.
There is a squelch in Linrad that is based on an FFT
analysis of the baseband. It works in all modes,
AM, FM, SSB and CW.

It would open the squelch at very low levels and the user
can set a delay to not loose the first fraction of
a message. Those who have an interest could make a wideband
recording available to me and I would make a video on how
to use the Linrad squelch.

Linrad is free software. Open source, with the most generous
licence. The squelch is a simple procedure that others could
implement. I think it is close to optimum.

Re: squelch debate

Siegfried Jackstien
 

several sdr software have such a funtion (simon also added it in sdrconsole v3)

i was wondering why not all commercial radios have such a function

for adding such a thingy to your "normal" rig you can use software like dsp filter from makito mori

or an external device like nir12 or sprachextractor lingua

... But why it is not inside radios????

when a homebrewers group with an open source firmware (like in mchf) can include it ... why not the clever programmers of icom, kenwood, yaesu ????

dg9bfc sigi

ps the nr in mchf does wonders :-)

mchf firmware now has such a function and it really serves your nerves
when listening to a longer conversation cause it significantly lowers
the noise in the voice (background noise) and there is almost silence in
voice pauses

it even can dig out a low quality signal OUT of the noise so it really
increases signal to noise ratio

if there is no readable signal it can not work but if you have a low
quality signal (barely redable with just a few db over noise) it lift
that signal up to a much better quality and readability

for older radios you can add something like sprachextractor, jps nir10
or 12, or ... several units now on the market but why it is not included
INSIDE the radios ?!?!

you wrote that you use mil radios?!?

what kind of vad (voice squelch) does those radios offer??? (i never had
such a unit or sit before on and have the luck to try it thats why i am
asking)

Most military and commercial radios have incorporated voice or
"syllabic" squelch for decades, and thus they are the only ones I use
for long-time monitoring.    They have been implemented in both
hardware and software as well, and the circuits/algorithms are
described in documentation from Stephens Engineering Associates,
Harris, Codan, and others.    Voice squelch on SSB channels is
essential for those who monitor particular frequencies for activity -
I built my first one back in the 1970s and have no idea why the ham
manufacturers have ignored such a useful feature.

I think it has been patented by some firms.
Icom's old version of VSC used to be quite similar, but their DSP version of it in later radios didn't work half as good.

Used several Sailor (S.P.Radio Denmark) maritime SSB radios with syllabic squelch.
It's quite magical.

Re: Airspy mini and rtl_fm

fyi, I tried so many combinations on rx_fm but audio from fm stations were extremely slow. Using GQRX, audio was fine and smooth.

I was planning on using use rx_fm to record NOAA APT similar to what I was doing using rtl_fm.
