KAM-XL symbol (was: GPS Setup SOLVED)

Lynn Deffenbaugh
 

What particular station was showing a boat vs a red dot?  I'd like to track down and explain the choice of symbol.

I can see you have got a Fix Quality of 2 in the GGA string which is very good. I am no expert in GPS, but I had to learn few things, forced by the hobby... I have experimented with Kantronics KAM-XL where you can find a similar setup, GPS wise. What I have noticed is that APRSISCE shows the KAM-XL GPS waypoins with a boat symbol (I am assuming it could because boats use a similar format in their positioning system?), aprs.fi on the other hand shows them correctly as waypoints (red dot). aprsdirect.com doesn't show them at all ( I learned aprsdirect.com doesn't show APRS Items either). aprs.fi won't show waypoints with a poor Fix Quality aka zero.
Good luck and regards,73 de J M0IPU YO3FCA

The first two lines may be a communication link or baud rate connection to your computer from the GPS. Once that function happens the gps is running and linked to your computer.

Hello group,

I found a section of the GPS dongle's configuration utility where you can tell the dongle how to send the NMEA strings. Two of the settings are called "Main Talker ID" and "GSV Talker ID". They were previously set as follows:
Main Talker ID: 0-system dependent
GSV Talker ID: 0-GNSS Specific

I'm far from a GPS expert (obviously), but I think the dongle was formatting the data strings differently based on what type of satellite system the data was coming from. I changed those settings to the following:
Main Talker ID: 1-GP (GPS)
GSV Talker ID: 1-Use Main Talker ID

After flashing those instructions to the dongle I reopened the virtual COM port in PuTTY. Everything is not coming through as $GPxxx type strings:

There is still all that funky stuff at the beginning, but I guess that's normal because it doesn't seem to be hurting anything. Anyway, when I engage the port in APRSIS32 again I get a full lock almost immediately, as expected.

Re: GPS Setup

Brandon Clark
 

Thanks for the advice Lynn. I opened a terminal session using PuTTY on COM6 and made a screenshot of the output:



It looks like I am getting a mix of different types of data? Some have the "$GPxxX" structure you mentioned, but others are beginning with "GNxxx" and "GLxxx". I watched the terminal for a while and the structure is always the same:
-Weird characters on the top row or two,
-$GNxx strings,
-$GPxxx strings,
-$GLxxx strings,
-$GNxxx strings

Could it be that the weird characters at the start of the data are messing up the interpretation? The $GPxxx strings are present, but maybe they are not getting read since they are bracketed by other data types?

Re: GPS Setup

Lynn Deffenbaugh
 

APRSISCE/32 expects NMEA strings from the GPS.  You can confirm this by opening a simple terminal program to the GPS port (assuming no other program has it open) and see if it is readable.  Each line should start with a $GPxxx and be a string of comma-separated values not all of which are numeric.

If you don't see this, and it is readable, post the results here.  If what you see is not readable, then your GPS is in a binary mode that will need an NMEA conversion somewhere before getting to APRSISCE/32.

Hello group,

Well, I've been trying to get my new GPS dongle working with APRSIS32 and am still stuck. I initially did not have the "Enables | NMEA" part going, but once I enabled that the screen displayed the expected elements: location and heading boxes, list of anticipated satellites, etc.

Where I'm stuck now is that the GPS data doesn't seem to be "getting into" the program. When i use the USB dongle with the included testing and config program (U-Center 8.26) I can get a position fix, see which satellites are being received, and so forth. So I know Windows 10 is able to work with the dongle.

Also installed is a virtual com port driver, which creates a COM6 for the GPS dongle. I double- and triple-checked the port configuration in APRSIS32 against what shows up in Windows Device Manager (COM#, Baud, Parity, Data Bits, and Stop Bits). Everything matches.

Now, the receiver is very configurable. My hypothesis is that the receiver is sending data in a protocol that the U-Center 8.26 program can decipher, but which APRSIS32 cannot. I think I have also found where I can flash the configuration to the receiver to change how it communicates.

My question is, what must APRSIS32 receive in order to read the data properly? It looks like there are multiple versions if the NMEA protocol. Which one should I tell the receiver to use? Are there any other settings I should look for in the configuration program?

Interesting. I'll have to study this more, Lynn.

We've a local ham who's scripted to send via RF, passes of the Fox birds. They'll start showing on my heard list when approaching in range and continue until out of the local range.

TH-D74A and GPS

Greg Isringhaus
 

Hey guys.  I'm wanting to do GPS with my TH-D74A over Bluetooth to APRSIS32. 
I had it working before and then I did a firmware upgrade and I lost all my settings.
Can someone help me out to get this going again?

Thanks all!
