I'm not sure how you might have interpreted my questions regarding I-gates and
Digipeaters as confusing the two--I have a good grasp of packet as I
mentioned in my original post.
The link you included was very helpful. I just finished reading it and have
as many questions as I did before reading--which in my case is a good
Now that I'm back at my QTH, I want to start defining good hill top gear--KPC
by Kantronics seems like a good choice but I'd certainly like to hear what
other node operators are using on their hill tops. Here, I have access to
some VERY good locations--locations that are very much needed since this is
serious canyon country. We are a responsive ham group here on the coast, so
I will certainly have plenty of good help too. Anyway, I'd like to use gear
that is future compatible (non-locked in firmware etc) so updates to APRS
routing can be facilitated without replacement of costly gear.
I think I'll set up an Igate here at my QTH. I only use Linux so any Igate
ops lurking, please feel free to post suggestions/help/tips via this list.
Just a quick perview of Igate software available looks interesting, however,
I will need to read much more about it since I don't want to listen to
traffic as much as I wish to add "our" traffic to the APRS servers.
I've been sending packets for over 12 hours and yet to have any heard by an
Igate using 5 watts and a very high gain antenna. It's very clear I need to
get a hill top digipeater in place to cover the towns of
Trinidad>Mckinleyville>Arcata>Eureka>Loleta>Fortuna>Rio Dell (These towns
account for most activity and usually can't hear each other even though
distance is relatively small). These towns are 0n HW101.
Finally, are backbones used for APRS via local digipeaters? I'd really like
to see how other communities like ours are set up to handle the difficult
terrain. Relieving packet dups/congestion at 1200 packet speed is obviously
Thanks again for your help, input, and review!
How much does free cost?
How much is free worth?
