Anyone know what the freqs are for packet nodes and bbs's in Miami, FL?
Many thanks.

Subject: Palm Pilot, Email, Packet?
The simplest way to do this would be to use APRS. APRS uses ONE frequency
everywhere in the USA. It is on 144.390. With a GPS connected, it will show
your dad's position to anyone who has access to the internet. It will also
send and receive messages. Your Dad will be able to send E-mail, but will
not receive E-mail. The station once set up is easy. There is PocketAPRS
which will run on a Palm pilot. Of course you will need a TNC to connect the
Palm to a radio, and GPS.
For more info on APRS here are some links.
http://www.findu.com/cgi-bin/find.cgi?k4hg-8 This is an example of what you
would see from the internet, as your dad traveled.
http://www.qsl.net/kd4rdb/aprs.htm This is an introduction to APRS and more.

Hope this helps,
Let me know if you need any more information.

Subject: PSK31 reception killed by RFI from PC...
The fact that the interference occurs on discrete frequencies (Prime and
regular harmonics) leads me to believe that it is the monitor. Try changing
the refresh rate and you may verify this. I had the same problem and this was
the cure.

I think it's 14.070 and it's the 3rd PSK31 signal from the left on the

Has anyone else besides me used this device yet. I have purchased
one, and have some user questions regarding its features, which the
company has not answered. If you have tried and used it, I'd be
interested in corresponding with you to compare notes on its use.
Please E-Mail me. Thanks.

Subject: Stupid Question
I've been reading up on Packet radio, and a question was prompted by
something I read, and I can't find the answer. A couple of documents
made a real point of differentiating between the data rate between the
computer/TNC and the TNC to the radio, as if they could ever be
effectively different. I understand data communications well, in
general, and I was wondereing, did I mis-read, or is there really some
effective difference?
I mean, if the highest effective bit rate out of the TNC is 9600, for
example, how can I possibly get more throughput?
Thanks in advance.

They usually are different. The TNC to Radio baud rate may be 1200
baud while the TNC to Computer (serial port) baud rate is usually much
higher (9600, 19.2, etc). The serial port uses a handshake (hardware
or software) to control the flow of data from the computer and prevent
the buffers in the TNC from overflowing. A higher baud rate is used on
the serial port in order to quickly fill up a packet during file
transfers so it can get transmitted by the TNC. That improves the
throughput. The total throughput is limited by the radio side though.
The throughput for 1200 baud is less than 1200 baud because of the
packet overhead (addressing, CRC check, etc). The more "real data" you
can stuff into a packet, the more efficient it is.

Memory. A TNC is essentially a big buffer and a modem. With enough
memory you can fill up the buffer and then signal the computer to hold
off until it's through.
The TNC hardware is generally a microcontroller and very low horse-power,
so terminal baud rates are limited.
