Ok, so I kinda got it working... apparently there is some issue with my
tnc-pi not transmitting =(

I tried to power cycle it but no go, I'll check the cables tomorrow
night... HOWEVER it is receiving! I haven't turned on the IGATE yet due
to transmitter problems but i'll leave it on over night and check it in
the morning =)

Speaking of I-Gates, here is something from Bob Brunigna to think about when we are setting up our APRS stations and considering I-Gateing.

This first couple paragraphs are the important part. This message is several years old, I do not know if the proposal has been adopted or not.

Robert/KF7VOP
All IGate operators please read and consider action on this proposal.

RX-only IGates kill the functionality of the APRS-IS as a universal system!
And they give casual observers the impression that APRS has global
connectivity, when in fact, that view has lots of invisible holes because of
RX-only IGates.

Compounding this problem is that we have no way of knowing if people are
using the right symbol for their IGate.  Are they using "I" because it is
really  a TX Igate, or just because it seems logical?

Using http://www.findu.com/cgi-bin/symbol.cgi?icon=Iamp&limit=2000 I see 960
"I&" Igates
Using http://www.findu.com/cgi-bin/symbol.cgi?icon=Ramp&limit=2000 I see 130
"R&" Igates

Maybe we need to have a 3rd symbol, a "T" Overlay so that operators of
serious two-way IGates and indicate their dedicated intent to provide good
APRS-IS local service.  These guys will take the trouble to indicate a TX
Igate.  When we see one of those, we have proof-positive that the IGate
includes a two-way TX capability.
We could even go one step farther.  We could indicate the NUMBER OF HOPS
that the IGate uses by default for IS-to-RF packets.  This could help us
better manage overlapping IGate coverage...  So how about this plan:

I& - is an IGate, but is ambiguous with respect to transmitting
R& - means it is definitely an RX only IGate
T& - Means it is definitely a TX IGate with one hop path only
2& - means it is a TX igate clobbering two hops in all directions
3& - means it is a TX SPAM GENERATOR , (or a legitimate special case)
Etc..

Should we do this???

Bob, WB4APR
