Voice Repeater Objects:

Now, as Alabama has begun adding Voice Repeater Objects to all
of its 15 UIDIGI ROM digipeaters (thanks tim!), we have a lot of
good feedback and have improved the text associated with the
display formats.  The "lines" refer to how the voice repeater
object looks when received on a D7 or D700 10x10x8 display
format.  Here are some examples.

1st line: is the FFF.FFF FREQUENCY (in place of callsign)

2nd line:  (actually beginning of Object text)

T123 R45mi - Combines PL and Range on one line. 
D234 R45mi - Combines DCS code and Range on one line. 
N45, S15mi - No tone with different ranges N/S or E/W 

3rd Line:   (begins w space if previous line uses 10 

Net 9pm W  - if it has regular nets worthy of note
Mtg 1st M  - if it has regular meetings 
144.875in  - optional for a non stndard input
 
4th Line: (The first 8 bytes will show on the D700, more will
show on PC clients ...

Also the DUPE issue on the APRS-IS has been resolved since we
have these OBJECT NAME Formats:

FFF.FFF-x - where x is one of 62 characters (A-z or 0-9)
FFF.FF+xy - where xy is one of over 3600 combinations

The +/- indicate offset.

With all these options, surely all of the 146.94 repeaters can
find a unique combination.  And the way I see it, the first one
that gets on the air, the better the choice.  Though it would be
nice to negotiate if there are conflicts.  Now that these all
appear on the APRS-IS, it is easy to see what is already in use.
Just http://MAP.FINDU.COM/146.94* to see which ones are on the
air!

So all this is on the updated LOCAL-INFO-INITIATIVE web site:

If you are going to get your locally recommended best travelers
voice repeater object on the APRS map, please do it before the
big Dayton Pilgrimage!

Thanks,
Bob, WB4APR
