;W0GQ-R *192245z4158.56N/09140.24Wr146.745- PL open

Well, actually no.  But thanks for asking..  I see a few
improvements that can be made.

1) Only the call shows on the map/D700 and not the freq.
2) It does not include the PHG data for displaying its range
3) It did not use the 111111z standard to make it permanent.

So here is how I recommend it:

;146.745- *111111z4158.56N/09140.24WrPHGxxxx PL is open W0GQ-R

That fixes all the problems and by adding the word "is", then it
fits nicely on the display of a D7 or D700 mobile.  You fill in
the values for the xxxx PHG digits.  If you don't know, just
tell me the estimated Height above average terrain in the area,
the estimated power, any favored direction, and the estimated
antenna gain and Ill send you back the right values.

Doing it the way I recommended, it will show on a D7 mobile
display as:

+------------+
| 146.745-   |
| PL is OPEN |
|  W0GQ-R    |
+------------+

And the PHG data would show as:

+-------------+
| 146.745-    |
| pw 9W h0040'|
| ant6dB omni |
+-------------+
 
If it was running 9 watts at 40 feet with a 6 dB omni antenna.
Most APRS clients would then plot a range circle around that
repeater to show it's useable range if requested.

Thanks
