Subject: [aprssig] APRS at Dayton
I hope to go to Dayton this year and hope to see lots of APRS activity.
I hope all travelers will set for VoiceAlert while enroute.
The operations of APRS in the center of Dayton can be greatly enhanced by
just a few SYSOP settings at the major DIGI's in the area. With these
remote-sysop settings, hundreds of APRS mobiles can be accomodated. See the
web page:
http://eng.usna.navy.mil/~bruninga/aprs/dayton.txt
Do we have the Dayton SYSOPS on here? Do they see this as a viable
approach? Who can guarantee an Igate in simplex range of HARA arena?
Mobiles do *not* need to change their mobile settings enroute Dayton,
assuming they are using the receomended New-N settings already
(WIDE1-1,WIDE2-1 or 2-2). That is the power of the New-N paradigm is that
the local SYSOPS can make a few simle changes to accommodate these hundreds
of users without expecting the users to change anything.
Either 1) TURN OFF your tracker when parked, or 2) Set packet rate to 30
minutes while parked. At Dayton, it is nice to see parked vehicles on all
the screens, but only at the low rate.
Since 52 will be useless, do we want to designate another simplex APRS
Voice frequency in the immediate area? Why not the 445.925 alternate APRS
channel?
Anything else?

On Hamvention Saturday, Bob will speak at the APRS Forum, which I am
moderating (at 11:30 AM in Room 3). I hope to see a lot of APRSSIGers in
attendance.

The Good news: Dayton has excellent APRS coverage potential for Hamvention
with existing stations and hardware. Only new hardware needed is an Igate
that is simplex to the arena.
The Bad news: A quick look on FINDU reveals that less than 10% of the
digis in and around Dayton are New-N compliant. Without New-N, it is
impossible for users or anyone looking at FINDU to tell what the local
Dayton network supports:
>30% lack any PHG antenna height info
>80% don't show their path support "Wn" or "W11"?
>20% still using RELAY and WIDE
Sorted by range from Hamvention:
TYPE CALL HAAT DIS DIR Comments
---- ------- ---- --- --- ----------------------------------
DIGI W8GUC 160' 4 NE No new-N, no path info, no Overlay
Home WA8ZWJ 40' 8 NW no indication of W1-1 support
Home KA8C 20' 8 E no indication of W1-1 support
Home N8QNM ? 8 NW no indication of W1-1 support
Home WA8VIW 80' 12 S no indication of W1-1 support
DIGI KC8QBL-3 ? 19 SE no PHG no New-N no path info no overlay
DIGI WB8BLV 160' 19 SW New-N with "S" overlay, W3 recommended
DIGI KC8KQE 40' 31 NE home, no new-N, no info, no overlay
DIGI WA8SDF-1 ? 32 SW no new-N no info, no recommends, no W1-1?
DIGI KC9CJJ-3 40' 36 W New-N recommends W3-3
DIGI KA8ZNY10 160' 40 SE old W-R-T, no New-N no W1-1
Simple fixes for Dayton Hamvention:
1) Have all HOME stations support WIDE1-1 as an ALIAS.
2) Have home digis show "W11" at start of their position txt.
3) Have W8GUC support only W1-1 during hamvention weekend and keep its
current "support" whether W# or W11 always updated in its position text.
4) put correct Overlays on all digis and include W# or W11 in texts
The nomencalture "W#" means for the digi to indicate the maximum number of
hops recommended in the area. If that is 2 hops, then put in "W2" if it is
3 hops, then "W3". Only if it is unlimited use "Wn".
The absence of any HIGH and wide area digis is ideal for a high density
situation like Hamvention, since it avoides the problem of bringing in too
much out-of-area QRM. But this then requires many home station or fill-in
WIDE1-1 digis. It appears to me that two more home-stations or fill-in
W1-1's are needed to the SW and SE about 8 miles or so.
Is there anyone local to Dayton that will take on these challenges, at
least to contact all of the above stations and do the simple changes to
W1-1 support, and update position-texts PHG's and W#'s so that the network
is self-explanitory?
Thanks.
Bob, WB4APR

Well, if y'all would stop buying stuff for 20 minutes I could get out of
the booth and go watch! =] Hopefully I'll have enough help this time to
be able to sneak out once in ahile and see at least one forum, and maybe
even spend more than $30 this year.
Still waiting for booth assignments, but I'll be there with OpenTracker
stuff, along with Jim from APRS World and Jason from RPC Electronics. All
of us should have more new gadgets to show off this year.
