[aprssig] Not Receiving Messages from APRS-IS

Hello All -

I am fairly new to APRS, but I think I have the basics down.

I'm having problems *receiving* APRS messages from the internet.
Sometimes it seems to work just fine, so I think my setup is OK.  Most
of the time, especially in my home town, I just don't get messages
sent to me via the internet.

Here's a simple demo.  I query my own call using the WHO-IS service
(via WIDE2-2).  My position and message make it to the internet just
fine:
20080519152034,N0JUH-3>APAGW,KC0IRJ-3*,WIDE2-1,qAo,KB0PJH:=3833.70N/09209.16W-PHG2230testing

20080519152102,N0JUH-3>APAGW,KA0GFC-2*,WIDE2-1,qAO,KA0GFC-3::WHO-IS :N0JUH{21

And the ack and response from WHO-IS appear on the internet:
20080519151156,WHO-IS>APJIQ3,TCPIP*,qAC,jFindU-QZ:>QRZ Lookup Server
20080519152102,WHO-IS>APJIQ3,TCPIP*,qAC,jFindU-QZ::N0JUH-3 :ack21
20080519152102,WHO-IS>APJIQ3,TCPIP*,qAC,jFindU-QZ::N0JUH-3
:N0JUH/G/JEFFREY J KUNCE/MO/USA{00
20080519152203,WHO-IS>APJIQ3,TCPIP*,qAC,jFindU-QZ::N0JUH-3
:N0JUH/G/JEFFREY J KUNCE/MO/USA{00
20080519152305,WHO-IS>APJIQ3,TCPIP*,qAC,jFindU-QZ::N0JUH-3
:N0JUH/G/JEFFREY J KUNCE/MO/USA{00
20080519152405,WHO-IS>APJIQ3,TCPIP*,qAC,jFindU-QZ::N0JUH-3
:N0JUH/G/JEFFREY J KUNCE/MO/USA{00

But I never see this at my station.

Shouldn't the IGATE that relayed my message know where I am and send
the response back so I can hear it?  How is this supposed to work, and
what is going wrong?

Thanks!

  -- Jeff, n0juh
