Update:

I have used Pocket Earth 3.5 to help show what I believe is my GPS running appropriately.

When setting up and detecting an operational port, my GPS detects and runs on Com5 with a rate of 1200, even when manually set to use the following configuration (GPS program port set at comm 8 and hardware port set at comm 4, with baud rate of 34800).

It both show:

Waiting for GPS data...

PSRFTXT,CHNL: 1273

GPRMC,235947.035,V,,,,,,,120806,,,N48

GPRMC,235948.044,V,,,,,,,120806,,,N41

another running capture shows:

GPRMC,000152.032,V,,,,,,,130806,,,N46

GPRMC,000153.032,V,,,,,,,130806,,,N47

GPRMC,000154.042,V,,,,,,,130806,,,N47

I believe this information shows that my device is functioning appropriately (but according to the reference below it looks like I am getting incomplete word groupings / sentences), but at the same point in time I can't get any other application to show a gps fix or even signal. I have used several radio stacks and left my device in the open for more than 20 minutes without so much as a small degree of signal showing up from any of the birds. I do get listings of the birds that are in the air, but not enough to lock or provide positioning. Does anyone have anythoughts or ability to translate the running feed shown above? I can get my tilt to function without issue, but my athena running PK 3.0 isn't happy...

Lastly, Googlemaps seems to provide a blue flashing dot from time to time, but won't give me anything better than a 5km ring of accuracy. The other apps don't even do that :-(

Any help, understanding, decoding, or tools would be greatly appreciated.

v/r

Alternate GPS sentences (other than $GPRMC - the default) may be enabled by setting the relevent bits of 'mode' in the server configuration line

* server 127.127.20.x mode X

bit 0 - enables RMC ( value = 1)

bit 1 - enables GGA ( value = 2)

bit 2 - enables GLL ( value = 4)

multiple sentences may be selected
