[aprssig] D700A TNC Problems????

Fri Sep 14 16:44:19 EDT 2007

You have to remember that what you see from the IS (FindU,
aprsworld.net, aprsdepot.com, etc.) does not ALWAYS show how your
station is working as it relates to digipeaters.  You may be getting
digied just fine by W4IAX-7, but the path to the nearest iGate (which is
responsible for posting your information to the IS) may be by way of
KI4ELU-7.  OR, they may both be getting you to a nearby iGate just find
but because the IS drops duplicate packets, only the W4IAX-7 digi is
getting 'recorded'.  

What your more concerned with is getting into the IS regardless of how.
If your positions are making into the IS, then all is well and good.

Subject: [aprssig] D700A TNC Problems????

Hello all. I'm riding from Fairhope, AL over to work each day and have
not been getting into the digipeaters that well. The KI4ELU-7 I get to
nicely when in range, but as I cross I-10 to the north, I do not get 
digi'd very good. When on I-10 I am VERY close to W4IAX-7 digi. See
below for my raw packets showing KI4ELU-7 as the first digi that picks
me up. Note that N4ESS-2 in the next batch of raw packets is picked up 
by W4IAX-7 digi even though he's futher away than I am. Can anyone
give me any ideas as to "why" W4IAX-7 digi does not pick me up? I'm
using a D700A radio mounted on a motorcycle.

HEre is W5WHT-7's raw packets showing W4IAX-7 as his first digipeater
most of the time with KI4ELU-7 only twice.

My concern is the TNC in my D700A isn't working correctly - I've read a
couple of posts about the TNC not transmitting correctly - perhaps with
packets digi'd for a couple of days, then not working correctlly.  Since
this radio is only a month old, I'd like to determine this early on if
possible. 

Also, there are several times when I get digi'd by the KI4ELU-7 digi,
but it never makes it to an Igate.  Perhaps the TNC is sending packets
that are almost out of spec and only KI4ELU can pass them reliably? 

Is there any way I can *test* this radio to check?

Thanks to all for any help,

Ken H> K9FV-1
