#
# Makefile for dxlAPRS toolchain containing:
# - afskmodem	soundmodem for afsk/fsk up to 19200 bd using Linux OSS
# - gps2aprs	aprs-tracker using some serial gps, produces axudp frames which
#				may be sent with afskmodem
# - gps2digipos	generates a beaconfile for a (mobile) aprs-digi,
#				using some serial GPS
# - sondeudp	soundmodem for RS92 (and other) wx-ballons using Linux OSS,
#				the produced axudp frames are beeing post-processed by sondemod
#				to generate aprs-beacons
# - sondemod	RS92 (and other) wx-ballon decoder (takes data from sondeudp
#				and generates aprs-beacons)
# - udpbox		very powerful aprs-digi and axudp "distributor"
# - udpgate4	very powerful aprs-igate server (with http-interface)
# - udpflex		interfaces serial stuff like TNC2, TNC3, KISS, RMNC
#				to axudp frames
# - udphub		L2 AX25 switch to process many Packet Radio clients on one
#				single AXUDP interface from Flexnet, XNET, ...
# - aprsmap		powerful APRS viewer based on Openstreetmap
# - profile		makes png Image with Geo-Profile of 2 Positions using srtm-datafiles
# - radiorange		makes png Image/tiles with radio illumintion of 1 or 2 Positions
#                               using srtm-datafiles
# - waterfall           fft from iq file  to png
# - downsample          shift frquency and resample iq file 
# - sdrtx               modulate AM, FM, SSB, Stereo-WFM to IQ-file 
# - ra02                radio module RA-02 to axudp
