What is PSKmail?</SPAN><BR><BR>PSKmail is a ham radio working mode, which uses
data traffic (PSK) : The clients and servers work in PSK-250 mode with and among
each other. Everyone can connect to anyone.<BR>An important element of PSKmail
is the interconnection of several working modes and transmission
media.<BR><BR>> APRS Automatic Positions Reporting System<BR>> Server
network<BR>> Email<BR>> Short-Mail (APRS)<BR>> Internet-file<BR>>
local mailbox<BR>> Weatherreport<BR>> Positionsreport<BR><BR>Many things
are possible. You can read and send email (fetch weather reports, send direct
messages) and update the ships position through the APRS system (= Automatic
Position Reporting System). PSKmail can provide access to internet services
specifically worked out for sailers. You can use all functions with the
Afu-license, but the servers can even be used without internet connection.
Without Afu-licence, many functions can only be used by logging in. Therefore
PSKmail in general is a SWL (listeners)-application !<BR><BR><IMG

style="FONT-WEIGHT: bold">2. What do you need for PSKmail?</SPAN><BR><BR>In the
simplest case (SWL, listeners), one only needs a SSB shortwave receiver, a
notebook, a connecting cable with cable interface*, and the PSKmail software
V1.01 Linux or the INTERMAR PSKsoftware Win 1.0 for Windows XP. Of course
licensed amateurs use a shortwave transreceiver (SSB) for
sending.<BR><BR><BR><IMG

USB<BR><BR>PSKmail is a narrow band mail delivery system used by amateur radio
hams via short wave (HF) communication.<BR>To optimize the reception quality,
you can switch on a narrow 500 Hz filter into the receiver. Most of the
transceiver can be retrofit with a narrow filter into the USBmode control. See
manual. The advantage of a narrow filter is, that the area of only 500 Hz is
bugged and you cant be disturbed simultaneously from serveral different
signals. Additionally or alternatively, you can use a DSP as long as the
recipient provides you.<BR><BR><IMG

PSKmail, what does it cost ?</SPAN><BR><BR><IMG
src="http://www.pskmail.eu/images/Bild%204.JPG"><BR><BR>The PSLmail software,
Linux and Windows are available free of charge. The user only needs the
equipment discribed above. For amateurs usually always available. To connect
transceiver and notebook, you need a small sound card interface. The cost
amounted to 10,00 to 100,00 , depending on the equipment.<BR>Small interfaces
only transmit the NF and turn the transceiver on.<BR>Complex interfaces control,
among other things, the transceiver for a possible server-triggered frequency
change.<BR><BR style="FONT-WEIGHT: bold">See www.pskmail.eu >

System</SPAN><BR><BR>The PSK-APRS-Random-Frequency 10.147,0 kHz dial should be
use by all servers, unless there would be multiple servers installed for
different frequencies. INTERMAR operates five servers at different frequencies
(see frequency-map).<BR>The PSK-APRS-Server is exclusively used for
PSK-APRS-Functions. There is no weather,<BR>email or file-retrieval
allowed.<BR>Special servers, at 20m, 30m, 40m and 80m, are available for these
functions.<BR>Other servers can be connected on the PSC-APRS frequency<BR>Then
you suggest a QSY-frequency and get a new QSY-release to the specified
frequency.<BR>The user has to change the frequency of his transceiver e.g. to
retrieve his mail.<BR><BR>Attention All other functions, WX Email and files on
