IBP International Beacon Project


IBP shows which of the beacons of the International Beacon Project is transmitting now.
IBP is a Linux program that helps one with monitoring the beacons of the International Beacon Project, by continuously showing which beacon is transmitting on which frequency, along with the distance and antenna directions by PA3FWM.

Echolink on Ubuntu Linux (with Wine)



Echolink on Ubuntu (Linux)

The default Windows Echolink installers work fine with Wine on Ubuntu.
1) Install Wine.
2) Download Echolink install.
3) Run install using Wine.
4) There will then be an Echolink Icon in Wine program files and on your Desktop.
5) Start Echolink and set-up your station info.
6) Have fun....

If you are looking for a native Echolink program for Linux read my blog here http://zr6aic.blogspot.com/2013/07/echolink-on-ubuntu-setting-up-svxlink.html

Packet Radio on Ubuntu using Soundmodem

Packet Radio on Ubuntu using Soundmodem (144.800Mhz)











I got my ax25 configuration working with soundmodem on Ubuntu.


1) Install soundmodem and all ax25 options with Synaptic Package Manager or with (apt-get)
1.1)The list of apps I installed. ax25-apps, ax25-tools, ax25-xtools, ax25mail-utils, ax25spyd, soundmodem,

sudo apt-get install ax25-apps
sudo apt-get install ax25-tools
sudo apt-get install ax25-xtools
sudo apt-get install ax25mail-utils
sudo apt-get install ax25spyd
sudo apt-get install soundmodem

1.2) I found this script EasyPacket (install it) http://www.w1hkj.com/EasyPacket.html .
It consist of a series of scipts to simplify the process of starting and configerating a user packet node, see documentation in /usr/share/doc/easypacket (after instillation) for mode details.
1.3) The document was in Spanish and I had to translate it with google. Here is the content.
****************************************************
README
Greetings, My name is Pavel and I am CO7WTCosta Milanes, a Cuban Amateur Radio

This packete software was created to provide aconfiguration standard in mind to facilitate the assembly of apacket station in GNU / Linux, is expected to be as automatic as possible throughout their development.

The ideas or main bases of this software are:

- Used to create 3 soundmodem software modems simultaneous / Individual
- Create three ports of packet: 1k2, 9k6 and 4K8,which correspond to the speed AFSK 1200, 4800 and 9600 AFSK FSK,or all together or each individually.
- As a GNU / Linux has to assign an IP address toScholarly interface, suggests the use of AMPR declared 44.128.xxsegment test for each of the interfaces on different network segments, you must reset the IP address what proveea your local coordinator, allocation is as follows:
IP Address Mode Speed ​​port interface
1200 baud AFSK 1k2 44.128.0.1 x0
4K8 AFSK
4800 baud ax1 44.128.1.1
9600 baud FSK 9k6 44.128.2.1 ax2
- Only taken into account the connections AX25;NETROSE BPQ and others are referred
- Default incoming connections to ttylinkd enrrutanis not actualemnte functional.
- The indicative NOCALL default and is configured using the packetconfig script.
*********************************************
I found the README a bit cryptic.

2) I did the following.


2.1)I run soundmodemconfig  you will need X window server if you are doing this remotely via ssh

sudo soundmodemconfig

Soundmodem config screen













2.2) Configure the sound modem as in the pictures above. ( it will save the config when you exit the app)

plughw0.0 could be different for your Linux depending how many Audio sound cards you have in your ALSA configuration.  

sudo arecord -l will list your device's

**** List of CAPTURE Hardware Devices ****
xcb_connection_has_error() returned true
Home directory /home/anton not ours.
card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 1: V10 [FUNcube Dongle V1.0], device 0: USB Audio [USB Audio]
  Subdevices: 1/1

  Subdevice #0: subdevice #0

plughw0.0  will be card 0


2.3) I connected the external speaker sound plug on Radio to laptop line in and tuned VHF radio to 144.800Mhz FM to see some local packet traffic.






























2.4) Select new configuration in file menu and then sound card.
On the older Ubuntu it was /dev/dsp (soundcard) new Ubuntu its (alsa and plughw:0,0) and your serial port (my port was /dev/ttyS0) for your PTT (I am using ZS1I radio interface between radio and laptop)

to see what is the list of serial devices run the command ls -al /dev/* | grep ttyS

crw-rw----  1 root dialout   4,  64 Sep  4 17:42 /dev/ttyS0
crw-rw----  1 root dialout   4,  65 Sep  4 17:42 /dev/ttyS1
crw-rw----  1 root dialout   4,  74 Sep  4 17:42 /dev/ttyS10
crw-rw----  1 root dialout   4,  75 Sep  4 17:42 /dev/ttyS11
crw-rw----  1 root dialout   4,  76 Sep  4 17:42 /dev/ttyS12

U can use the terminal program to see if its the correct serial port.
Install minicom serial terminal program.

sudo apt-get install minicom

sudo minicom

select  X to exit


2.5) Then select file new channel in the soundmodemconfig ( Select modulator and demodulator afsk the rest of the defaults should be ok.)
Change your cal-sign in Packet IO tab.

2.6) Select Channel menu on left and the click on Diagnostics menu and click on scope. You should see your audio from your radio ext speaker. ( if you get an error you have the wrong audio device change it until it work)




Set the volume on receiver for reasonable level (You might have to set the level with sudo alsamixer)


Sudo alsamixer

Use the F5 and F6 keys to select the sound card and input M also selects options

2.7) Exit the soundmodem config program. ( it will save the config on exit)

2.8) There should be a config file in /etc/ax25/soundmodem.conf

2.9) make a copy and rename it to soundmodem.9k6.conf

3) you can now start the easypacket script (sudo packeton 9k6)

3.1) you should see something like (The following interfaces are ready to rock: sm0 ZR6AIC)
hi......
Almost done.
you could now monitor packet in listening mode with the following commands. (sudo ax25spy or sudo  listen  has changed to sudo axlistin -c -a).

Weather satellite reception with Funcube and WXtoImg (ubuntu)

Weather satellite reception with Funcube and WXtoImg (Ubuntu)

















I am using QUISK,QTHID and xwxtoimg on my Ubuntu to receive weather satellite reception.












Still trying to get the bandwidth bigger in fun-cube but here's the details so far.

I am using a mobile 2M 1/4 wave mag mount on roof for reception Antenna.

1) Start QTHID
2.1) Change the frequency to one of the following.
2.2) Polar orbiting satellites TX freq 137.10 137.40 137.50 137.62 or 137.9125 50ksz or NFM until you receive a satellite. Satellite will pass twice per day
about 12h apart.
3) Start QUISK.
3.1) select FM and click on center of wave.
4)Start WXtoImg.
4.1) Firs time you use WXtoImg set your location it is needed to calculate your satellite time and freq. (wxtoimg -G)
4.1) select file update Keplers.
4.2) Click on Satellite Pass List.
4.3) select freq for next pass on QTHID.
4.4) Select Record and the image and then OK.
4.5) Play with volume control to get best results.
4.6) Band with on fun-cube still to narrow still puzzling out how to make it wider.

Satellite News


Cubesats Deployed From Vandenberg Atlas V Launch

The Atlas V NROL-36 launch from Vandenberg Air Force Base in Cali- fornia, originally planned for August, successfully launched on 13 September at 2139 UTC.

This launch carried a satellite for the National Reconnaissance Office. Also aboard this flight at four cubesats as part of ELaNa IV mission and seven cubesats for government missions.

Several hours after launch Justin Foley, KI6EPH, announced via the #Cubesat IRC Channel that all eight P-PODS had successfully deployed.

The ELaNa Cubesats aboard are:
+ CINEMA (Cubesat for Ion, Neutral, Electron, Magnetic fields)
   o Downlinks for engineering telemetry and command are in the 2400-2450 MHz range; Science telemetry is in 2200-2300 MHz range.

+ CSSWE (Colorado Student Space Weather Experiment)
   o Downlink 437.345 MHz, 9k6 with AX25

+ CP5 (PolySat)
   o Downlink 437.405 MHz at 1 watt, AFSK on LSB AX.25 over NRZI at 1200 baud, every 2 minutes, begins 3.5 hours after first turn-on.
