Thanks Joeseph
I appreciate your comments. It's a like visiting another country where no one speaks English.¬† It's easy to get lost. We stumble around and hope that we end up somewhere safe. ūüėä. I probably should not have ventured into the first order of draws but I couldn't resist because it's exactly what I wanted to simplify my portable station. I have it working with wsjt-x and js8call. I am proud of that.¬†
On the other hand, if only experts had purchased the first edition, then the developers would get a totally skewed impression. Clear and simple user guides are going to he critical to the success of this project. This is a human endeavour, not just technology. 
I really want this to work. I think it's a brilliant idea and I support their work completely. 
Thanks again, Joeseph.

Re: Setting up auto time with draws gps #ntp #chrony #gps #clock #battery

 

Budd,

If you have the GPS attached as a refclock, and it is active, it is actually a better time source than the Internet ntp servers.

As has been discussed previously.  NTP services like chrony slowly adjust the system clock based on information obtained from both ntp servers and refclocks (like the GPS and PPS).
 
Basil has created a script that verifies time at ~/n7nix/gps/verify_time.sh
 
The command line to do a quick update of the clock is:   sudo chronyc makestep

You can verify your clocks with: chronyc sources -v

The battery backed RTC in the GPS must be set by the GPS once it has acquired the time reference from the satellites.
 
In my opinion, NTP time synchronization works best if the computer is not powered down and the Raspberry Pi is well suited to continuous operation at low power consumption.  With the computer running continuously the chrony daemon can keep the system clock well synchronized whether using the GPS/PPS and/or network connections.  (It ignores sources that are not reporting or are way out of sync.)

Re: Unable to resolve hostname with RPi Draws

 

Use the program 

sudo raspi-config

to set the hostname, and then reboot.

Usually get this symptom if you set the hostname then do not do a
reboot. See instructions here:
https://nw-digital-radio.groups.io/g/udrc/wiki/DRAWS%3A-Getting-Started
Note the "Now reboot your RPi" after you run ./app_config.sh core

What do you get when you run:

hostname

if you do not get 'bobspi' then reboot & type: hostname again.

as root run:
chronyc makestep

Then send me the output of:
cd

It's a little confusing because the DRAWS image uses chronyd for the NTP
service and NOT ntpd.
So there are 3 situations:

No gps antenna
No Internet connection
No gps antenna or Internet connection

I have a script that dumps the world for chrony here:
n7nix/gps/verify_time.sh

It's also good to see how many satellites the gps is picking up with:
gpsmon

Usually if your clock is off by a lot & you are connected to the
Internet you can kick it in the butt as root with:

chronyc makestep

My experience as well, except when one might want to setup tunnel connection as part of the ampr.net (‚Äú44.‚ÄĚ Net). I plan to be doing that with some DRAWS functions. I thought that was a big deal out there in the PacNW.

 

Jack ‚Äď kd4iz

So, in the majority of whatcom county, from my understanding almost everything is handled via fsq, I think a few other modes are used for transmitting data however I don't think ampr (44 net) is used as much (or at least i've not seen it in any discussions on the MT Baker digital group).

also, the thing to keep in mind is that not everyone is going to use this board in the same way (I don't ever think i'm going to do an rms gateway or winlink on my setup), it might be a good idea to do groups for what people want to do (ie aprs with fldigi for example, or aprs with winlink and rms gateway and bbs)... this way people who want to only do a few things (like aprs and fldigi) don't have to wade through the more in depth/specialized options (ax.25/rms/winlink/etc) that they probably will never need or want
