Of course, you have to be in simplex range of these frequency
objects to see them, because if they are beaconed over areas
where they are not useable, then they are SPAM and should be
erradicated..  But that being said, if you are in range of ANY
APRS digipeater then its locally recommended local voice
frequency object should show up on your radio.

That is simple.. EVERY DIGIPEATER is supposed to provide this
frequency object to its users.  Basically, the DIGI is making
sure that all APRS mobiles within its (the digi's) footprint are
being informed about the recommended VOICE repeater in the
digi's coverage area.

Notice the distinction.  This is -not- a frequency object for
every voice repeater.  It -is- supposed to be -ONE- recommended
voice frequency object in the vicinity of -each- digi.

Every digipeaeter is supposed to use its BTEXT for this object.
See how on www.aprs.org/localinfo.html

I need your help to contact every digi operator in your area
(and anywhere else you stumble across them) and make sure his
digipeater is doing this according to the New-N paradigm
settings since 2004.

When you drive through an area, and don't see these objects on
the front panel of your radio, then get on the air, find the
local voice repeater and ask them to contact their local APRS
sysop and findout why not?
