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
4. ubuntumate> ubuntumate
5.>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

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
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.
ICOM> This program controls ICOM radio transceivers and receivers with the CI-V option.
