A computer and packet TNC (terminal node controller), which is like a

for HF, not VHF. On VHF we operate 1200 baud with wide shift. On HF, we
are limited to 300 baud and very narrow shift. The Kantronics KAM '98 is
such a modem:

======================

Thanks.

Several more questions:

Is the Kantronics TNC comparable to something like the SCS PTC-IIpro
which is the recommended unit for SailMail?

They have alot of the same features except for the one you really need
for SailMail. That being Pactor II and Pactor III modes. The SCS TNCs
are the only ones to offer it because it is proprietary.

How would you automate sending a new position packet every hour or so?

The TNC does that for you. At least my KAM Plus does.

Is there any acknowledgement that your position report was correctly
received?

I'm not sure, but I don;t think so. The position reporting used by Winlink
is
though. I don;t beleive SailMail has any position reporting feature but I
haven't used SailMail for a couple of years.

Can a position report be sent to APRS via EMAIL?

Not as far as I know, but check their website for lots of details.
