Is APRS runnng on HF? Last I used it, it was only operating
on VHF.

Did a search for my question, but didn't find anything, so if I missed
this, I apologize.

Getting ready to sail a new boat from San Francisco to Newport, OR in
May, and we'd like to let the home folks know every couple of days that
everything is OK (or not). So my question, is there was a way to use
SSB to communicate with a shore based phone line? Something on the
order of using the SSB to call either a phone, or a shore station that
could relay a message, or something.

I've read on this forum how to use the SSB to send/receive email, and
we'll be working that issue, but wondered if there was a simple, legal
way to "phone home".

Thanks in advance for any help.


There are very FEW Public Coast MF/HF Stations left operating along
US Coastal Waters, since AT&T closed KMI, WOO, and WOM a few years back.
I don't think there are ANY Regional MF Stations at all any more.
You could find one of the Private Coast MF/HF Stations that might handle
you message traffic, but very few, if any, of those have Phonepatch
capabilities. Your best bet, is to get a Ham Operator onboard as a crew
member, and have him run your traffic thru the Ham Radio Networks. I
know a few of these type guys, who specifically crew delivery voyages,
just for this purpose.

I agree about the ham types. I suggest a simple HF Amateur Position
Reporting System (APRS) so exact GPS position reporting is sent out and
any
family/relatives, etc., may access the APRS web site and type in a FindU
command and follow your progress. Do a web search on APRS and you will be
surprised what ham are doing with this technology. They even track search
and rescue dogs equipped with GPS and VHF/UHF flea power transmitters.

Tune your HF receiver to 10.151 LSB and listen to the APRS network on HF.
It's at the very top of the 30 meter band. The two tone modulation on LSB
puts it a hairs width inside the ham band.

30 meters works great 24/7 most of the time.

I'll check it out. I had very good luck with the position locator
in Winlink while cruising. Family and friends got a real kick
out of knowing where we were.

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

Larry, what else do you need to transmit or receive the position
reports on 10.151?

The entire setup consists of a radio, TNC, GPS, and a computer.

A computer and packet TNC (terminal node controller), which is like a
special modem for packet HF radio. To operate on HF, you'd need a TNC made
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:
http://www.kantronics.com/kam98.htm
It is made to directly connect to your NMEA 0183 GPS and will beacon APRS
over your HF ham SSB radio. It operates many modes:

GTOR™
PACTOR
AMTOR ARQ, FEC, SELFEC, CCIR 476 & 625
PACKET 300, 1200 or 9600 bps
RTTY
NAVTEX / AMTEX
ASCII
WEFAX
EMWIN
HF e-mail
CW
GPS NMEA-0183 compatible
TELEMETRY
REMOTE CONTROL
REMOTE SYSOP ACCESS
HOST Mode
KISS

many useful for boaters, like NAVTEX, WEFAX, PACTOR, and AMTOR which is
called SITOR on the marine bands. HF email is also included. When plugged
into the computer, the computer runs a terminal program made to command the
KAM which automates its use.

If you plan on leaving it to automate HF email delivery to its built-in
email box, get the 512K Memory expansion for it.

It'll run fine just connected directly to your 12V house batteries. It
draws little power, around 150 ma.

Of course....you'll need a GENERAL CLASS HAM LICENSE to use it. This isn't
an emergency comm.

I have a KAM+ I'm willing to part with. The only thing I've ever used it
for is APRS.

Thanks.

Several more questions:

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

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

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

Can a position report be sent to APRS via EMAIL?

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.

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.
