Waterfall

2022-08-05T21:03:10Z

OE2LSP:

== Beschreibung ==
Mithilfe erwünscht! Wer kann/will hier Informationen beisteuern? Bitte Info per Mail.

waterfall ist ein Tool um aus einer IQ Datei bzw. einer Pipe ein Wasserfalldiagramm zu erstellen.
"Max-Hold" Wasserfall um auch lange Zeiträume in einem Wasserfallbild darzustellen.

Dieses Tool wird beim SDR-Buffer benutzt 
https://wiki.oevsv.at/wiki/SDR-Buffer 
https://websdr.iks.tugraz.at/sdrbuffer/

Beispiel:
./waterfall-x64 -i /media/DUMP/20200915/1256 -o 400 -C -w test.png -x 1600 -y 5 -j 65000 -b 17 -d -c col.txt -z 85

Um das selbe Ergebnis mit unterschiedlichen input Bandbreiten zu erhalten, müssen die Werte bei den Parametern -j und -b angepasst werden.

== Varianten ==

* waterfall
* waterfall3
* waterfall.py

== waterfall ==

=== Übersicht der Parameter ===
<nowiki>
waterfall -h
Make Waterfall image out of IQ-File
-b <brightness> gain (20.0)
-c <file> read colour lines "<index> <r> <g> " (0..255) gaps interpolated

-j <ms> in roll-mode (-r) wait ms till next subsample taken from near eof
next image written in this time*oversample at system clock second change
on system clock jump max. 60s will be filled or left out
-m mirror image vertical
-o <n> oversample <n> times with peak-hold before draw next line (1)
if -r and IQ-file is a pipe: -o seconds/line -j samples/line
-r roll-mode with image line from last position of (growing) IQ-file
IQ-file may be removed/rewritten any time
-t unfilled part of image is transparent
-w <file> waterfall image png in roll mode written every new line
-x <pixel> image x-size, prefer 2^n for no pixel interpolation
-y <pixel> image y-size, if not -r default as filesize
-Z <%> threshold for blacklevel in % of pixels/line below black (10)
-z <level> manual noisefloor blacklevel, 0.0 for automatic (0.0)

-j <ms> in roll-mode (-r) wait ms till next subsample taken from near eof
next image written in this time*oversample at system clock second change
on system clock jump max. 60s will be filled or left out
-M make median of "-o" lines before draw it, default peak-hold
-m mirror image vertical

Downsamples iq input, e.g. to extract Hamradio band from raw SDR input with more bandwidth.
This tool is used at the SDR-Buffer 
https://wiki.oevsv.at/wiki/SDR-Buffer

Beispiel:
./downsample_x64 -a 0.1709 -F u8 -f u8 -i /dev/stdin -l 64 -o /dev/stdout -r 0.1709

Downsamples 2.048 MHz bandwidth to 350kHz 
-l and -a are used against aliasing effects. 
-s is necessary if not the center of the spectrum should be used.

Panorama

2022-08-05T20:21:56Z

OE2LSP:

== Beschreibung ==

Dieses Tools wurde ursprünglich für die HamnetDB geschrieben. Es kann aber auch auf der Kommandozeile verwendet werden, wenn man es selbst nutzen möchte. Auf weitere Details gehen wir an dieser Stelle aber nicht ein, da der normale "User" eher keinen BEdarf an diesem Tool hat. Vertiefende Informationen gibt es direkt bei Chris OE5DXL.

Die grafische Oberfläche für dieses Tool kann unter https://hamnetdb.net/rftools unter Panorama gefunden werden.

Hostint

2022-08-05T20:09:53Z

OE2LSP:

== Beschreibung ==

Mithilfe erwünscht! Wer kann/will hier Informationen beisteuern? Bitte Info per Mail.

Tool um beispielsweise einen PacketRadio( PR) client wie tnt und axudp zu verbinden

Beispiel: hostint -i OE0XYZ-5 -t /tmp/hostmode -U 44.143.40.90:10094:10096 -v

-i ist das Rufzeichen der Station die sich zu einer PR-Gegenstelle/PR-Digi "-U" verbindet, 
-t ist der pfad zu peudo schnittstelle des Programms wie tnt. Im Beispiel von tnt legt dieses einen Symlink zu /dev/pts/XY an, der Symlink dafür befindet sich unter /tmp/hostmode

== Übersicht der Parameter ==
<nowiki>
hostint -h

-h this
-i <mycall>
-t <tty:baud> baud=0 is pseudo tty
-U <x.x.x.x:destport:listenport> axudp /listenport not check ip
repeat -U for more ports
-v verbous
