Hi,
this [ https://sourceforge.net/projects/automodrecog/ ] is my little
effort about handling IQ files.
The input IQ file is recorded with HDSDR, very nice piece of sw, that
as a good recording scheduler. By the way the file provided can be
played with it. I do also some tests with IQ file produce
sible to refine this task... I've a
lot to study!

Good morning,
I'm exploring QT graphical, to begin lo leave WX widget
I'm looking for good infos about resizing / fix the dimensions of my

Moreover in WX there's a Notebook container, very useful with crowded

Hi ,
take a look at my [ https://sourceforge.net/projects/automodrecog/ ] and
tale a look at pyplot docs... not Gnuradio but it work!
My app generate a plot as analysis's result and creates a PNG image
embedeed into an html form.
Bye,

Hi Dirk,
in my experience SDR is a nice stuff but sometimes analog tech can help:
try to lower total NF using a tuned LNA in front of you receiver... RTL
dongles or other sampler are a bit deaf and noisy, and your signal seems
very feeble.
... my 2 eurocent... !

Hello!
About frequencies pay attention that there are more than a single (406.025
MHz) frequency.
In my direct experience there's also 406.028 / 406.039 MHZ in use. So also
tuning has to be on the right frequency.
Take a look also at

i Vicfield!
another info for you: are you palying with a "real" EPIRB signal or with a
"test" signal?
In the first case be sure that the signal cannot reach the open space:
the signal "trigs" an expensive and complicated stuff, actulally it's
starts a S&R process with a lot of people involv
Hi Mehmeto,
in my opinion and in my experience with LEO sats, it's usefull to retune
the receiver using doppler correction info coming from external app.
In the past I used to query old beloved Predict via socket to control a
ICOM PR1000 receiver with a little utility that I wrote ( google "pcrsat"
try ' arp -s 'ip number' 'mac-address'

Hi everybody,
I need to "switch" randomly 5 different signal generator via selector block
every [say] 3 seconds
So , in GRC, I've a vector_source with values coming from
[random.randint(0, 4) for p in range(0,4)]. This put some random values
displayed right.
Now how I can scan the vector, a v

In my experience "rf inserting" 1pps into early receiver (sampler) stages,
maybe "coding" timing with 1pps && 10Hz, all derived from gps reference.
This "affect" the signal under analysis but that can be do only
periodically... for multilateration ;-)

Nice!! just what I was looking on... got big IQ files and look in deeper as
second-pass analysis.
Next days, I'm abroad now, I'll make some tests.
Tnx GhostOp !!!👍

Take a look also at LimeSDR... there is a "mini" version for about 150$.
If I recall right it's a fullduplex 12 bit ADC/DDC, ranging 1MHz / 6GHz
with 20 MSPS, with USB port.

Good evening,
I'm trying to make a multimode receiver using a PlutoSDR; all the
demodulation and visualization parts work correctly.
Now I would like to use a click'n-point tuning and as a result I have
tried to understand something more about the use of controlports.
I followed some tutorials and

Good afternoon,
yes Marcus, just a "quick look"!
Good afternoon David and list!
Recently I had your same problems developing an application ( a SDR
transceiver, mainly for satellite ops, based on ADALM Pluto).
The main headache was " how I can *click* on the waterfall and *tune*
there?...", clearly invoking some variable interaction then yor
