Re: GPS NMEA monitor software for the Pi
Stephen Farthing
Doug, Google is your friend here. From a search I found this article which is a good start :- You may have to write some code in Python to get exactly what you want. One of the issues is that there is no common way to put every GPS into NMEA mode. I have some Motorola ones and an some Trimble ones and they all require a different string to be sent to the GPS to put it into NMEA mode. Both have various proprietary modes as well as NMEA.?
Hope this helps, Steve G0XAR |

Have you checked out gpsd yet? I know it gives the base level of outputs but as for S/N,I didn't notice that. Nice thing about gpsd is that it can be accessed by any other program via TCP. Looking at using it to provide a basic ntp server for me for when I do not have Internet access to keep times up to date for meteor scatter and FSK144/JT usage.

Re: GPS NMEA monitor software for the Pi
Hi Max,
Yes, I can see the ASCII strings on my Pi using Minicom. So I know the NMEA data sentences are there. I just need a linux program to parse the data and put it into a human readable display, something like VisualGPS which works for that horrible OS known as Windows!
Thanks,
Doug, k4cle

Re: GPS NMEA monitor software for the Pi

The NMEA data just streams as ASCII text, so you should be able to "see" it in a terminal session
toggle quoted message
Show quoted text
For serial number I guess you need to send the GPS a command also simple ASCII.... I have no idea what... I guess the NMEA command set is defined some where on the www ... Max On 20/06/2014 06:15, 'Douglas N. Baker' kfourcle@... [Raspberry_Pi_4-Ham_RADIO] wrote:

GPS NMEA monitor software for the Pi
Hello All,
Anyone in the group know of a good GPS receiver software program for monitoring the NMEA data sent by a GPS receiver? I have looked on the net and found some Linux programs that display the position on maps but I have not found anything that will just a simple display of the basic S/N levels, lat/long, etc. Had thought this should be simple but I haven't found any such so far. Thanks... Doug, k4cle |

Xastir no offline maps
After a bit a of a struggle? I got APRS working using a USB sound card direwolf, soundmoden and xastir. I have a few questions?
1. how do I find, download and install? maps for xastir for offline use. 2. how to I get ax25? soundmodem, configured in MKiss mode to work remotely as a server so I can use it? like? dirworlf as an agw server for windows PC apps like UISS or APRIS32? 3. what ax25 programing resources out there? Eventually I want to use the Pi as a High altitude balloon flight computer and tracker. I just want get used programming the Pi (python and C++) by? a program to listen for aprs packets? then put the data in a spread sheet. comma-separated values. I wan tdrive around with the pi for grins to survey what it can pick up. |

¿ªÔÆÌåÓýTurns out it was VERY good advice and the source of the problem.?

Been in Digi mode for over 36 hours now with NO issues. ? A permanent fix will be a smaller choke and a metal case ¨C trip planned to Radio Shack later today, ? Thanks! ? Clay N7QNM ??? ?

Dire Wolf 1.0 now available.
Dire Wolf is a software "soundcard" modem/TNC and APRS encoder/decoder.???It can be used stand-alone to receive APRS messages, as a digipeater, APRStt gateway, or Internet Gateway (IGate).? ??It can also be used as a virtual TNC for other applications such as?,?,?,?,?,?,?,?, and many others. It runs on Windows and Linux systems including the Raspberry Pi. New features in version 1.0 include 9600 baud operation and?new interfaces for operation with software defined radios (SDR) such as??or?.? More details: |

John do you have a rough idea on price?? I would have to wait for bult boards.? Will they also throttle down if needed to 1200?? I have two GE Rangr UHF radios that are almost ready for these.?? One going in a high spot locally and one going in my Van. Sounds great!On Tue, Jun 10, 2014 at 3:51 PM, John Hansen coastalchip@... [Raspberry_Pi_4-Ham_RADIO] <Raspberry_Pi_4-Ham_RADIO@...> wrote:

I do not know. Good question. I think the alinco line has some. A better option is a commercial? rig.? I forget the make. But I will find out. 73 On Jun 10, 2014 7:24 PM, "Bill Vodall wa7nwp@... [Raspberry_Pi_4-Ham_RADIO]" <Raspberry_Pi_4-Ham_RADIO@...> wrote:

Ohio Linux Fest
Hello ALL:
I just wanted to share this link regarding a Linux Fest Oct. 24-26 2014. "The twelfth annual Ohio LinuxFest will be held October 24-26, 2014, at the Greater Columbus Convention Center in downtown Columbus, Ohio. Hosting authoritative speakers and a large expo, the Ohio LinuxFest welcomes all Free and Open Source Software professionals, enthusiasts, and everyone interested in learning more about Free and Open Source Software." In addition if anbody is so inclined, the organizers are open for people to give presentations. I'm thinking such a presentation by utilizing the R Pi and other Linux stuff would bea good way to promote amateur radio. See this link for details. 73 John KB3SVJ |
