has a hard-coded 500 ms TXD. That completely destroys any increase in
throughput you might get by going to 9600. You could put a LOT of FEC data
on the packet, though!</FONT></SPAN></DIV>

<DIV><FONT face=Arial color=#0000ff><SPAN class=428142219-25092006>Bellow is a
message of a discussion we have been having for about a month now on 9600 baud
UHF APRS that we are experimenting with on the NW APRS Group Network. It
looks like we are coming up with another innovative more efficient APRS
network. Maybe those of you who are innovative and curious on helping to
pioneer a more efficient APRS Network should subscribe to our list to follow
our development. Maybe some other congested areas want to give 9600 baud
a try. I am sure Bob King K7OFT would be more than willing to help you
get started.</SPAN></FONT></DIV>

nwaprssig@nwaprs.info<BR><B>Subject:</B> Re: [nwaprssig] D700 UHF APRS
DIGI<BR><BR></FONT></DIV>Thanks to both Bob and Scott for their efforts. We're
breaking new ground here. Far as I know, there is no other APRS interest group
with a 9600 baud UHF activity. The plan to expand the system here in Spokane
is coming along. I'm still looking for a home for the 9600b digi. It needs to
be mountaintop or tower top somewhere near Spokane. <BR><BR>I think we have
the digi settings all worked out. We'll leave them on the wiki pages, but I
will duplicate them to the website shortly, now that we have settings ironed
out. This is critical with using a D700 as a remote digi, because unlike the
KPC-3, there is no remote connect to make further changes. It would take
another trip to the hill for those changes. <BR><BR>Come on Portland OR and
Vancouver BC, any interest in your neck of the woods?<BR><BR>Let's spread this
good stuff faster than the bird flu!<BR><BR>David<BR><BR>

not sure, but Scott may have been referring to the original file we
used<BR>to set up the D700 on UBALDI. That file is stored on my
home computer and<BR>my laptop. It has been modified to correct
for the BEACON E 15 error. It <BR>has been changed to BEACON E
90.<BR><BR>By the way, I did some testing with the D700 DIGI on
Baldi to test the<BR>decrementing feature of WIDEn-N. The results
of the testing show that the<BR>D700 DOES indeed decrement a WIDEn-N
packet. And that was done with the TNC <BR>set in the
configuration shown on the wiki page. I would encourage
others<BR>to verify this.<BR><BR>The test that Scott just finished this
weekend when he traveled to Eastern<BR>Wa. and earlier tests I have done in
Eastern Wa and Puget Sound, and <BR>comments from others taking up
440.875MHz 9600 Baud operations here should<BR>once and for all put away the
commonly held notion that you need super<BR>strong signals to work 9600
Baud. It is simply not true. My field tests
<BR>indicate that 9k6 works as well as and in certain situations, better
than<BR>1k2 operations. Give it a try!<BR><BR>Scott, thanks for
putting the APRS 9k6 Baud DIGI on Baldi. It will<BR>certainly
open lots of eyes.<BR><BR>Bob
