The time of DB9 sockets being over, USB / RS232 adapters are now used. The COS signal tells the RPi a signal is being received by the radio with the correct CTCSS tone. I wanted to modify one and attach a transistor to the GPIO lines to act as PTT.
#ARRL RTTY PATCH#
I have submitted the following patch to soundmodem v0. Save the settings by typing radio tune save You may now test the setup to see if it repeats audio. The interface between the repeater and the Raspberry Pi controller is a modified CM108 chip based USB sound card. There are slight differences Inexpensive sound card CM108 IC7300 internal PCM2901 sound card 2. net> * * \par See also SignaLink USB Interface. Although these aren't usually connected it is possible to modify some of these interfaces to make this available for use as a PTT function or to build an interface from scratch using these devices. Most other projects on the web are using adapters based on the CM108 chip. From the list below, select the contest or call sign for which you want to view records, select the desired geographic area and then click on Go.Cm108 radio interface Having the key ingredients and the rest of the parts in my junk box I decided to put together a "radio-less" node interface that will also make a great test box.
