echo What is the phone number to text?
read phone
echo What do you want the text to say?
read msg

value="\"@ALLCALL APRS::SMSGTE   :@${phone} ${msg}\""
echo sending $value

printf '{"params": {}, "type": "TX.SET_TEXT", "value": %s}\n' "${value}" | nc -l -u -w 10 2237
echo

echo
echo Your message is ready to send
echo Go to JS8Call and press the send button

Is it possible to send a message this way without having to press SEND in js8call ?
