[... confusion and typos ...]

Jack None of the ~180k packets I have have two asterisks.

Roger Sorry, typo. For a frame header decoded by an AEA/Timewave TNC,
Roger it should of course have been -
Roger KB5WIAWIDE2*APRS:$GPGLL,3759.519,N,12218.458,W,2 32104,A*3A

Right, but that's not what I saw, which is why I asked. If I had seen
that, I would have understood it to be what you explained.

Roger The main point being, that, as I said, most WIDEn-N digis set
Roger the 'H' bit when the SSID is decremented to zero.

I need to reread the AX25 spec until I understand all of the bits.

Jack.

Uh... Is there an Idiots Guide to APRS? I recently got a Knwd D700, it's
really slick and I'm interested in learning more. I downloaded the spec and
looked over the digi paper referenced on Jeff's site @
http://www.dididahdahdidit.com/text/digis.txt over in Woodstock (I'm
nearby), but there is still many details assumed. It's all still over my
head except for hooking up the GPS and using it. I'd like to gain an
understanding of the basics. Should I understand packet first? A simple
glossary of terms would be a good thing. I may just try to corner Jeff.

Callsign substitution when using RELAY and WIDE is probably not the
norm.


Though not yet universal, callsign substitution is _quite_ common in my
area, where many are using Kantronics or PacComm TNCs.

What station is repeating this packet? I can't tell. What's supposed
to happen here?


These two packets were sent by a couple of high-elevation WIDEn-N
digipeaters on mountaintops ringing the SF Bay area.

There are two implementations of WIDEn-N -

Mixing the two can result in misleading information.


NOID is far better for determining network topology, and is recommended.
This recommendation is by, not least of all, the Father of APRS, Bob

WB4APR,
who worked with Kantronics to enable the WIDEn-N protocol in the first
place, and the guy whose idea WIDEn-N was.
