Re: LF: vlfrx tools question

Paul - thanks for advice. Apologies to others as this is a bit OT.

Ntp is now running from the gps. However, gpsd still required additional 
commands to work.
This command:

    sudo gpsd -bnN -D3 /dev/ttyACM0

gave error messages about:  " can't bind to IPv4 port gpsd, Address 
already in use"
While looking on other ntp websites, I saw a note that if  using 
Raspbian Jessie or later, a systemd service (installed by gpsd) should 
be disabled as it interferes with manually run gpsd instances. After 
giving the commands:
    sudo systemctl stop gpsd.socket
    sudo systemctl disable gpsd.socket

Then command:

sudo gpsd -bnN -D3 /dev/ttyACM0

runs without error, giving various launching and listening INFO messages 
from gpsd  and the wanted result shows in ntpq.
Now I know the system can work, I'm hoping I can avoid all this 
procedure each time by using an appropriate config file so that gpsd/ntp 
can be initiated to run correctly in the background at boot up?
Just for info, I am running Raspbian Jessie Lite on a RaPi3 with an 
Octosound. vlfrx tools is installed and working.
