Use "expect" after installing it via "pacman -S expect". Then build the 
script:

autoexpect /usr/bin/simpleusb-tune-menu

and after entering the desired inputs "V" etc., run the resultant script 
from the command line or via cron, and parse its output to get what you 
want, e.g.:

# ./script.exp | grep -A3 "^REAL"
REALTIME RX TELEMETRY DISPLAY:
     COS     |   COS   |  COS   |  CTCSS  |   CTCSS    | PTT
(composite) | (input) | (test) | (input) | (override) |
    CLEAR    |  CLEAR  | CLEAR  | IGNORE  |   CLEAR    | CLEAR

The man pages for expect and autoexpect are of course more informative, 
but this simple example should pique your interest as it meets your request.
