The packets aren't in ASCII TNC2 command-mode format, so no receiving station will understand them with the first 16+ bytes of the frame not compliant with the AX.25 protocol specification.

<div>Here is what I got. I never gated it. I'm guessing that its
because it was not a KISS frame???? I'm not sure what FLDigi
needs to see to forward it over the KISS interface. I'll have to
work on setting up some sort of test bed so I can test it end to
end.</div>

<div>I think that was me.I am going to try again today if I
can. I was centered on 1700 Hz. I could see the data going
out, it sends the RSID, a gap, and then the text. Maybe I
need more power, I was sending at about 20 watts. :)<br>

<div>Around 09:01 EDT (1301 UTC), I copied these RSID
transmissions without any following traffic. Do these
look like the times you tried?<br>

<div>What kind of transceiver were you using?<br>
</div>
<div><br>
</div>
<div>What exact "dial frequency were you on?<br>
</div>
<div><br>
</div>
<div>Were you on USB? (Most ham transceivers try to
default to LSB below 10 MHz, and must be overridden to
USB.)<br>
</div>
<div><br>
</div>
<div>Was the center frequency of the cursor in the FLdigi
waterfall exactly on 1700 Hz?<br>
</div>
<div><br>
</div>
<div>Did you see your transmitted string appear in the
upper (buff-colored) window of FLdigi?<br>
</div>
<div><br>
</div>
<div>Were you trying to send from a KISS-linked APRS
application, or did you just hand-enter a string
directly into FLdigi?<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>The RSID mode ID sent before the actual transmission
is very reliable and will often be decoded even when the
actual transmission on MFSK16, PSK63, etc fails to
decode. This could happen if the radio frequency of the
radio, or the audio tones in FLdigi are off.<br>

<div>You MUST be within 20-30 Hz of the correct frequency
for a successful decode to happen. This includes the
total of any error in both the RF frequency and the
audio frequency in FLdigi.<br>
