The TinyTrak's sister device, the WXtrak does exactly this (if you have
the right weather station to connect to it).
Quoting the website:
"WXTrak is a weather information encoder which, when connected to a
compatible weather staion and a radio, will transmit the weather data at
an adjustable rate. It is a construction project based on the TinyTrak3,
and provides an inexpensive way to transmit weather information without
the need for a full TNC.
WXTrak is configured by connecting to a computer's serial port, and
running a simple configuration tool which allows setting of all user
options. It transmits the APRS weather protocol. Since it is designed
around the TinyTrak3, It is available with an optional case.
Currently supported weather stations include the Radio Shack WX200, the
Oregon Scientific WM-918, and the Peet Brothers Ultimeter 100, Ultimeter
800, Ultimeter 2000, and Ultimeter 2100. Future versions are expected to
support Davis and Dallas 1-wire stations. "

Umm, another stuff is

You can use the Ultimeter weather stations which you can go directly to a
KPC-3+ or similar TNC and it will work! KF4OTN-4/6 is setup this way... No
computer.

Hi all,
First of all let me correct one comment. There are actually 3 CHANNELS, 4
freqs, dedicated to digital transmissions. CH 70 156.525 DSC calling (voice
comms not allowed); CH 87A&B 157.375 (ship TX) & 161.975 (ship RX) this is
Automatic Identification System (AIS) duplex repeater; CH 88 B 162.025
(ship TX and RX simplex) AIS.
A few additional comments regards CH 70 in addition to Charlie's points,
there are several more that you may find very interesting. CH 70 is also
the DISTRESS channel. When a sailor hits the DISTRESS switch on his radio,
regardless of what CH the VHF radio is setting on, the radio switches to CH
70 and transmitts the MMSI identifier, Boat name, Lat/Lon and "NATURE" of
distress. The sailor can key the distress either for his own boat or he can
relay another boat in distress. He has the options of selecting the
following designations: EXPLOSION, FLOODING, COLLISION, GROUNDING,
CAPSIZING, SINKING, ADRIFT, ABANDONING, PIRACY, MOB (Man Over Board).
Another interesting point is any vessel within range of the distress call
will automatically switch channels, provide an alarm and display the posit
and nature of distress. Of course you are duty bound to assist if you are
close enough and should coordinate with any other vessels on CH 16.
The AIS channels are what I find so interesting. I have my ICOM M602
connected into a KAM+ and display the data streams that are transmitted by
all commercial vessels entering & leaving TampaBay. The raw data string
looks precisely like a standard APRS transmission. The field separators are
different but it is very easy to detect the Lat/Lon ; Speed; Course, I have
subsequently been able to determine ORE Carrier; Container ship, Cruise
ship, however there are some 15 additional 3 number codes that apparently
are for work boat icons. But the bottom line is I can manually edit the
data string and save it to a DOS APRS app and it plots the ship's track in
and out of the Bay. Very obviously this is a major commercial version of
APRS!
Now the point about this system that has captured my intrest is the fact
these big ships have much better range on their VHF AIS transmitters than
private boats. I have consistantly recorded their positions at 35+ miles
away! Much futher than any small boat radar can reach. Obviously the point
here is you could have solid data of a freighter's posit, speed and course
long before you could see him by radar or visual. What a godsend at night!

You might add that they are also using this on HF.
Do you have some of this data captured that you can send to the SIG? It
would be kinda interesting to see some of this data parsed in real time...

Just to follow up on my last posting...
(Taken from http://www.navcen.uscg.gov/marcomms/high_frequency/rtchansi.htm)
Global Maritime Distress & Safety System DSC & Radiotelephone Channels
The simplex DSC frequencies are guarded and are used for digital alerting
and calling for distress, urgency and safety. Once the DSC call has been
sent, the corresponding radiotelephone frequency is used for voice
communications.
These simplex voice frequencies are used for distress and safety
communications, and (except for 2182 kHz) are not normally guarded.
DSC VOICE DSC VOICE
2187.5 2182 8414.5 8291
