How much bandwidth does the mobile ham really need?
most questions, there are several answers to this. The best one
probably being "it depends on your lifestyle". If you are used to
broadband internet access and don't want to give that up when you are
en route, you are a potential candidate for internet access via
satellite, and you will have to bear the cost of that luxury. If on the
other hand you are en route to relax, and you don't need instant
information, you could try PSKmail for
bare bones information delivery. Pskmail gives you a 500 Hz wide
channel to the internet. This is enough to get the most important
email, the weather forecast and the daily update on the sunspots. Being
nomadic, we live on a boat during summer and in a camper during winter,
I get by with 200 Hz and a half hour session with the server most of
the time. How much email do you really need daily to keep up to date?
course we combine daily PSKmail with a webmail session once a week, to
get the 'picture ' if you know what I mean. And to get the non-ham
I can upload software patches to the internet on a daily basis while
living on a Mediterranean beach which does not have a ADSL socket.

use PSK, MFSK and THOR modes, including the new robust PSK modes which include soft viterbi

protocol only allows 1 connected client at the time. Bandwidth (3dB)
using the maximum speed (PSK500) is max. 500 Hz,
providing a net throughput of ~2600
characters/minute including ARQ overhead.

linux and OSX. The server is written in perl.
Applications include a Mailbox (port 24) allowing down/upload

messaging via APRS(port26),

was only available for Linux, the java client started early 2009 and
has now taken over from the perl client, so that pskmail is now
compatible with all common operating systems. VK2ETA joined the team in
2009, with valuable contributions regarding robust psk modes for
fldigi. John also did most of the work for the translation of the modem
code from C++ to java. The work on the mainstream client focuses on transfer of email
