<div class="moz-cite-prefix">But to the original poster's question
about being "received by an I-Gate", and to clarify the actual
meaning of the tones of the D72, here's a copy my reply in the D72
Yahoo group:<br>
<br>
The "two-tone audio feedback" doesn't mean that your packet was
received by an IGate. The only way you can tell that is by
independently monitoring the APRS-IS via the Internet.<br>
<br>
What it DOES mean is that your packet was digipeated AND the
repeated packet was copied and decoded by your D72. The original
packet, or the digipeated packet, or some subsequently digipeated
packet (depending on your path settings) may or may not be copied
and decoded by an IGate, there's no way to know that from the RF
side.<br>
<br>
It is VERY common to not decode a digipeat of your transmitted
packet so you cannot read any success or failure criteria into the
presence or absence of the "two-tone" sound.<br>

most important thing to realize is that if you can hit TWO
digipeaters, then the chance is very high that you will NOT
get a “MY PACKET” display since both of those digis will
BOTH digipeate your packet at the same time and you will
always get a collision.</span></p>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">But
this is very easy to know. Just –listen- to the APRS
channel. If you hear an immediate digipeat of your packet
and the noise is strong (even if it is a cgarbled collision)
then you know it got out even though you will not decode
it. </span></p>

<span
style="font-size:16.0pt;font-family:"Tahoma","sans-serif"">I
was on two Summits On The Air climbs recently and I was
trying to get spot information posted via APRS regarding
my operational parameters: frequency and mode. When I
sent regular APRS packets with the current info in Status
Text as well as messages sent to SOTA, I very seldom got
the two-tone audio feedback that they had been received by
an I-Gate, so I kept sending them. When I got home I
found that a large number of my packets and messages had,
indeed, been successful in getting into the system, so
most of those repeats were not necessary. Is there some
parameter I need to change on my TH-D72 so that I get
feedback on APRS packets and messages which succeed in
entering the APRS web system?<br>
Thanks and 73,<br>
