Raspberry Pi and Amateur Radio (Apps and more)


have a raspberry Pi or want a raspberry PI?

this is the best thing going for now. it is a full blown computer on a 2x2 board
HD audio
HD Video

1GB of memory and FAST

and very little $$$ compared to what you are used to!

here is a link to check it out:rasp pi

software list for ham radio is XXXXXXX

then i will point you to what you can do with it with Ham radio

ham radio/raspberrey pi>hamradioscience


to get a raspberry pi to work with linux (raspbian) the drivers were already there for many ham radio apps

to get the audio working for raspberry pi and linux:

install alsa a mp3 tool and wav to mp3 conversion:

> sudo apt-get install alsa-utils
> sudo apt-get install mpg321
> sudo apt-get install lame

enable sound module, then reboot
> lsmod snd-bcm2835
> sudo modprobe snd-bcm2835

then just use
>aplay xxxx.wav


there are a few Ham Radio Linux distributions for Raspberry pi:

1. KB1OIQ Andy ham radio for linux>KB1OIQ
2. raspberryconnect>RASPBERRYCONNECT
3. raspberrypi.org>RASPBERRYPI
4. ubuntumate> ubuntumate
5. linux.org.au>australian linux group



for digital modes ham radio and linux you need a new radio or some type of tnc or analog to digital converter.

so there are a few: Rigblaster - by west mountain radio or signlalink by www.tigertronics.com/slusbmain.htm

Ham radio deluxe is only for windows you CAN run wine but good luck people say it works ok
but I prefer not to run wine ( I might as well run windows)
so programs i would suggest:
FLDIGI for most digital modes CW, rtty, psk
ECHOLINK echolink
VOACAP
ALARMEJT>alarmjt
FREEDV>that allows any SSB radio to be used for low bit rate digital voice.
MMTTY > rtty
MMSSTV> slow scan tv
WSTOOLS>Linux version of the JT44 and FSK441 communications protocols, usually described together as WSJT.
HAMLIB>HAMLIB LINK
ICOM> This program controls ICOM radio transceivers and receivers with the CI-V option.
