Transmit prerecorded CQ from linux to TRX with one tuch key


One way to automate the work with a microphone - playing frequently repeated phrases from a computer.
This version allows you to work without X, from the console, does not require a powerful computer.
It requires a connection to the transceiver for both digital modes of operation, the transmission 
is controlled by the RTS line RS232 (including and USB-COM devices)

For transmit need make ttyptt.c and simple bash digicq


cc -o ttyptt ttyptt.c

Next change PTT port to you use at top of digicq file, pre-recorded audio files (.wav) and audio device. List audio device see like

aplay -L 

aplay -l

my option
#! /bin/bash

ttyport=/dev/ttyUSB20
snddev=plughw:0,0
track1=ew1ln-eng.wav
track2=ew1ln-rus.wav

#--------------------------
Next change hot key you want use and, maby, add more keys in "case" and edit help string
 
"(e-engl, r-rus, q-quit) >"


    case $input in 
    
    "e" ) 	if ! ./ttyptt $ttyport 1 ; then 
		    exit 
	        fi;
		echo $texton;
		aplay -D $snddev $track1; 
		./ttyptt $ttyport 0;
		echo $textoff;
		let counter++;;

    "r" ) 	if ! ./ttyptt $ttyport 1 ; then 
		    exit
		fi;
		echo $texton;
		aplay -D $snddev $track2;
		./ttyptt $ttyport 0;
		echo $textoff;
		let counter++;;

    esac
    
    done
Screen in work if you don't use RS-232 PTT, try rigctl from utilities to support the hamlib radio control library
rigctl T: 
	set_ptt                        
rigctl t: 
	get_ptt
