someone who thinks they know everything and won't listen to anyone
else... We have a lot of the latter around.
I've been reading and replying on the Blackberry so had limited access
to the available data.
Now with more information such as only a single i-gate heard and gated
you, not just that no digipeaters acted upon the packet, we're on a
As Jason has indicated, your "tweaking" of the TX level could be the
culprit. Excessive deviation is the usual culprit for lack of receive
by other stations. Be glad you got the data you did, and recovered the
payload... put this knowledge in the brain bucket and move on to more
The usual culprit for "issues" like you initially reported is lack of
understanding of the function of the APRS-IS.
BTW, welcome to the hobby, and have fun climbing the learning curve.
If you haven't already check out the GPSL reflector and APRSISCE/32 as a client.

may still be able to decode the tones. Distant ones where your signal
is weaker may not be able to. You have probably heard this on a voice
repeater or even on simplex. A distant and noisy station can be copied
via a repeater if he backs off from the mic. If he starts shouting, the
deviation goes up. More energy is outside the passband of the receiver
and eventually the signal is too noisy to copy or the squelch might
even close. If you are simplex, you can try opening your squelch. If
you are on a repeater, you're out of luck. It's the same with packet.
You are better off having the deviation set properly. It can be done
by ear, but a deviation meter or service monitor would be better.
Lacking one, just crank the deviation all of the way up and then
start turning it down. When it starts to sound quieter, turn it down
some more. It will get you in the ballpark, but checking the actual
deviation would be better.
Perhaps you could check the actual deviation before you change
anything. So... could over-deviation explain why only one iGate
