[amsat-bb] DUCHIFAT1 - first 'Compressed APRS' tests

[Herzliya Science Center]

Dear all,
We have experienced some problems in the registration process at our web
site.  Our students are working on fixing these problems and we estimate
this might take a few days.
We appologize for the difficulties some of you have experienced and we
appreciate your patience.

Please do not give up, and try again after we will notify you that the
problems are solved.

In the mean time you are welcome to try to receive and decode the
satellite, send us telemetry, and prepare your setup for sending COMPRESSED
APRS packets to DUCHIFAT1 after we will fix the registration issues.
(packets must be 14 bytes long "COMPRESSED APRS".  Regular APRS or MIC-E
won't work here.)

The Herzliya Science Center radio teachers - Shamai 4Z1WS and David 4X1DG

> People with the ability to send Compressed APRS location packets are

> The satellite will collect these packets worldwide along its flight at
> 620km high orbit, and will downlink them from time to time over our ground
> station in Herzliya/Israel.
> Participants are kindly requested to register in advance in order to get
> their packet identified on the map.
> The packets successfully received will be displayed on a map in our
> Internet site and  QSL cards will be sent via Bureau to the stations
> registered and recognized. (unfortunately, there is no way we can recognize
> packets from unregistered stations because the packet is limited to 14
> character at the satellite, so we assign two unique characters to every
> registered station to enable us to identify them).
