ARCTIC-Expedition mit PSKmail geplant !

UA3ATS/KK5NT

Dear Rolf,

I'm Oleg (UA3ATS/KK5NT), a head of radio communication of Around-Arctic expedition "Polar Ring" 
(http://www.ec-arctic.ru/eng/pr/). The expedition usually uses R3CA call-sign on the route (R3CA/0, 
R3CA/9, R3CA/m, etc.). During our last journey in spring 2007, we extensively used APRS technique (as R3CA-7) in 
order to bring our position and hot information to HAM radio society as well as Internet users over the expedition 
web-site. The main parking frequency was around 14.103 MHz (European APRS network). However, our APRS activity in 
2007 showed that such a common approach is completely unavailable for our case. In addition to the weaknesses of 
AX.25 protocol, we got a lot of transmitted stations just on the frequency (as a DIGIs, GATEs of anyhow+). So, less 
than 10% of our spots were captured by APRS stations and even less - forwarded to the Internet+ Here, let me say - 
we thank you kindly for your valuable help: as far as I know, a lot of our APRS spots were captured and forwarded to 
the Internet namely by your control station DL0IMA. Thanks again, Rolf!


Now, we are working hard under the upcoming expedition in spring 2009. Our main goal - the crossing of Arctic Ocean 
from Russia to Canada over the North Pole using the special cross-country vehicles on extra-low-pressure tires.


Thus, currently I analyze different ways to use APRS and e-mail facilities in that expedition. A very long path 
(more than 2000-3000 km) and relatively weak signals (RIG 100W, ANT GP 2,5m on the roof of the vehicle) force us to 
seek for a robust narrow-band modulation and respective control stations. Your PSKmail system and PSK activity in 
general seem to be the most promising ways here. Our route will go through the drifting-ice of central Arctic, 
so, from this viewpoint, our vehicles looks like a Yacht in the Ocean, hi!

So, I would ask you about possibility of our mutual collaboration in APRS and e-mail communication during the 
upcoming TransArctic expedition of 2009.

73!

Betreff: [pskmail] PSKmail development status and plans
Happy new year to all readers of the list!

Happy new year to all readers of the list!

We have had quit a turbulent year with PSKmail. Version 1 of the client has been released, 
and there have been experiments with new functionality of the server.

I think this is the right time to write a few words about where we plan to go with pskmail.
The first pskmail meeting in Zweibruecken, Germany in September 2008 organized by DK4XI of INTERMAR-ev was important to get all noses into the same direction, and we were able to agree on a long to medium term strategy for pskmail. And you will soon see some of the new developments which were started there quite soon.

The most important conclusion was that version 1 of the pskmail client is quite mature, 
and that we split the development path into:

* Maintenance of version 1 of the client (bug fixing etc...)
* Porting the client to a windows version for Intermar-ev
* Porting the client to java?
* Further development of the protocol towards multi connect

What is actually happening at the moment?

* Windows client version *

Rolf, DK4XI and his crew are almost ready to release the windows version of a pskmail client especially made for use on yachts at sea and in harbour. Additions to the Linux client include integration with zyGRIB, a program to show weather charts based on GRIB files or IAC Fleetcodes. The idea is to broadcast this weather information via the INTERMAR network. These broadcasts are in PSK250, and PA0R is developing a special FEC protocol to make reception of the broadcasted files easier, and more free of errors.
The server will get the additional capability to grab the files from the internet (from NOAA). The coding is based on using only the 16 shortest varicode characters, which enables use of FEC without significant inclease of the duration of transmissions ( IAC fleetcodes use characters 0...9 which take twice as long to transmit  :) 
When the INTERMAR servers are not broadcasting they are standby for APRS messaging. All this will enable the use of pskmail for SWL's i.e. yachts and other mobile vehicles with only RX capability!!

* Platform independent client *

We are looking at a JAVA port of the client, which could run on all platforms. If we decide to do it this will mean lots of work, so don't expect anything useable soon. But first experiments show that java may be a practical platform. We will use the present server version as a reference application for the protocol.

* Multiconnect on the server *

First testing is going on at PA0R with a protocol version where the server is a master and the client is a slave. (In fact, this also works peer-to-peer, the calling station is always slave). In this version (> 1.03d) the slave does not poll, and only transmits status info when it receives a poll or status block from the master. First experiments show less overlapping transmissions between server and client. The latest version  (1.03f) still does not work properly, more testing will be involved.
The server does not need to be changed for these experiments.
Long term goal is to use DAMA on the master (normally a a server), so more than one service can be connected simultaneously by more than 1 client without increasing chaos on the qrg...

* Waiting for Fldigi-3.1 *

Fldigi 3.03 has a serious bug when used with pskmail, resulting in unwanted memory dumps on the frequency.
In fldigi 3.04xx this has been solved. Moreover the new pskmail clients use the arq interface, which has not been officially released as it will only work with fldigi 3.04xx or fldigi-3.1 which will be the official release...
The fldigi interface in the server is still to be changed to the arq (tcp) interface.

* Packet radio network connectivity *

PSKmail server 7.21 contains a telnet agent which allows connecting the existing PR network via pskmail.
For this some special middleware is being developed. DA5UWG provides a platform to facilitate the testing 
necessary for this.

* Streaming agent e,g, for DX cluster connection *

We get many requests from contesters using remote locations without an internet connection.
Although it is already quite easy to provide this facility through the telnet agent I am looking 
into a more efficient (FEC) coding to use the broadcasting facility to set up  a DX cluster link...

As you see there is still enough work to be done. Lets hope 2009 will allow us to develop pskmail 
further towards an HF digital network with even more practical use!!.
If you can help, just yell at us via this list...

Rests to wish you a happy, prosperous and healthy 2009!

73,

Rein PA0R

Vortrag: PSK-Mail im Notfunkeinsatz*

Beim 1. Fortbildungsseminars des Distriktes Württemberg in Obersteinbach
hat der Notfunkreferent des Distriktes P, Jürgen Mayer, DL8MA, PSKmail
vorgestellt.

PSKmail ist eine Amateurfunk-Betriebsart die den Datenverkehr (PSK) 
benutzt: Die Client- und Server arbeiten im PSK-250-Mode miteinander und
untereinander. Jeder kann mit jedem Verbindung aufnehmen. Wichtiges
Element von PSKmail ist die Zusammenschaltung von mehreren Betriebsarten
und Übertagungsmedien.

Diese Eigenschaften und betrieblichen Möglichkeiten die PSKmail bietet
können für den Notfunkbetrieb sehr gut genutzt werden.

PSKmail benötigt keine aufwendige Infrastruktur wie z.B. Relais, Digis,
Linkstrecken usw. Gerade bei Notlagen und Katastrophen muss man davon
ausgehen das ein grosser Teil der Kommunikationssinfrastruktur und der
Stromversorgung ausgefallen ist.

MODEM- Windows-Version für PSKmail     fldigi V3.02

Das Soundkartenmodem  fldigi ist eine Software für digitale Amateurfunkbetriebsarten. Z B PSK, Amtor, CW usw  ähnlich MixW. ( Windows Variante)

Wir benutzen das Programm fldigi in unserer Software  PSKmail V 1.0
Mitdem obigen Programm kann man die PSKmail Daten empfangen undmitschreiben. Man hat dann einen kleinen Überblick über die BetriebsartPSKmail sofern man nicht die  PSKmail Version als bootfähigen Stickladen kann.

Notwendig ist ist nur ein Verbindungskabel zwischen Empfänger Nf-Out und PC-Nf IN

Esist geplant eine PSKmail Windowsversion zu schreiben, Basis ist dannauch das hier zur Verfügung stehende Programm fldigi für Windows.

Bitte eine kleine Weile Geduld.....
