TERMINAL EMULATOR AVAILABLE ON CARTRIDGE FOR COMMODORE COMPUTERS
DIGICART>64, a cartridge version of DIGICOM>64, the TNC emulator program
for the Commodore 64 and 128 computers, is now available. The cartridge
features auto-booting, making it ideal for unattended operation; should
there be a power interruption, the program (and parameters) will reboot
automatically. The cartridge is also ideal for Commodore users without a
disk drive.
A unique feature of this cartridge is the ability to rewrite and save
parameters without the need for disk access. This is achieved by using a
2864 EEPROM for parameter and text storage. No battery backup is needed to
maintain data storage.
Each DIGICART>64 cartridge includes a 25-page instruction book. Note that
the DIGICOM>64 modem (see QST, April 1989, page 76) is required for
DIGICART>64 operation.
More information on DIGICART>64 is available from:

MICROSAT/UOSAT LAUNCH DATE PULLED IN
Arianespace officials have informed AMSAT and University of Surrey that the
launch date of the MicroSats and UoSAT D and E satellites has been pulled
in by ten days and is now planned for January 9. The date change is the
result of the postponement of another mission, designated by Arianespace as
V35A, that was planned to lift-off on December 13.
Apparently, there are technical problems with the primary payload of the
V35A mission and it will not be ready for launch on schedule, so,
Arianespace officials decided to use this extra time to prepare for the
next flight, known as the V36A mission. They feel that pulling in the
MicroSat/UoSAT launch date by ten days is feasible because the MicroSats
and UoSATs, along with the primary payload, SPOT-2, are ready to fly.
The launch campaign began on November 27 with the payload integration teams
from AMSAT and the University of Surrey, along with their satellites,
arriving in Kourou, French Guyana. By December 20, all of the payloads
will be fully integrated aboard the ARIANE IV rocket and the teams will
then return home on December 23. After a short Christmas break, the final
AMSAT/UoSAT teams will travel back to Kourou and stay there to monitor
their respective satellites until the launch.
The UoSATs have completed RF tests in the screen room at University of
Surrey and have been exposed to low temperature tests in the clean room
"freezer" at -20 degrees C. Marc Fouquet, designer of the CCD camera
on-board UoSAT-E, has been taking "bench-mark" images for comparison with
orbital images. Totally "black" images have been collected to provide data
for image processing using the Transputer Data Processing Experiment - also
on UoSAT-E in collaboration with the European Space Agency. Additional
solar simulation tests had to be canceled due to the advance in departure
date and the spacecraft are now undergoing final cleaning and assembly in
the clean room.
Uplink and downlink calibrations in an RF anechoic chamber are planned
providing that the chamber can be made available within the very tight
schedule. Numerous visitors from several countries, as well as the UK,
have recently come to the University to view the new UoSAT spacecraft.

AMSAT-NA SPACE SYMPOSIUM
AMSAT held its 1989 Space Symposium and Annual Meeting on November 3-5 at
the Meredith Corporation's facilities in Des Moines. This facility
provided an excellent meeting place for the hosting organization, the
Central Iowa Technical Society. Radio amateurs from around the world
traveled to Des Moines to be part of this event.
The Symposium began on Saturday morning with Jan King, W3GEY, Bob McGwier,
N4HY, Tom Clark, W3IWI, Jon Bloom, KE3Z, and Harold Price, NK6K, presenting
a detailed rundown of the MicroSat program. NK6K gave an interesting
review of digital store-and- forward software, which he, N4HY, and Jeff
Ward, G0/K8KA, are developing. Following the MicroSat discussion, Stan
Sjol, W0KP, and Bill Clapp of Weber State College (WSC) summarized the CCD
camera experiment and other scientific experiments which will fly aboard
the WEBERSAT MicroSat. Also included was a sample high- resolution picture
taken with the WSC CCD. Rounding out the morning session was Dick Jansson,
WD4FAB, who discussed the Phase IV geostationary satellite design effort.
After lunch, Courtney Duncan, N5BF, AMSAT Vice President of Field User
Projects, discussed the many exciting activities related to OSCAR-13, for
example, Operations Nets, ZRO Tests and the upcoming MicroSat launch. Then
Franklin Antonio, N6NKF, presented his satellite tracking program,
InstantTrack 1.0. After Franklin, there was series of papers about the
exciting scientific missions in which AMSAT and OSCAR satellite users are
being invited to support including the Solar Sail, Lunar Polar Orbiter and
NASA's Small Expendable-Tether satellite experiments.
Following these papers came Jeff Wallach, N5ITU, Chairman of the Dallas
Remote Imaging Group, who presented a paper on high resolution weather
satellite image processing. Showing slides of weather satellite pictures
processed on his IBM-AT computer, many of the Symposium attendees were
overwhelmed by the pictures that N5ITU's computer produced. Bill Brown,
WB8ELK, closed the day with his presentation on ATV experiments with
balloons. Bill showed a videotape of his latest high-altitude balloon
experiments in which one of his balloons reached an altitude of 133,000
feet! Attendees were awestruck at the sight of seeing the curvature of the
earth at that height. Most interesting was the trip back to earth after
the balloon burst with impact impending.
After an "attitude readjustment," the Symposium attendees returned to the
Meredith Corporation facilities for the banquet and awards ceremonies.
Over 50 awards were presented to AMSAT volunteers in recognition of their
service to the AMSAT organization, the MicroSat program and the furtherance
of OSCAR satellite program.

MICROSAT MODEM TEST TAPE AVAILABLE
If you are building one of the TAPR or G3RUH 1200-baud PSK modems for the
soon-to-be launched MicroSats, a good way to bench-test your modem is by
using a cassette tape which Jack Mathias, W9FMW, is offering. This
cassette tests your modems without requiring a "live" signal. Also, you
can be sure that the rest of your system is operating correctly before the
launch of the MicroSats. To obtain W9FMW Test Tape For TAPR/G3RUH Modems,
contact AMSAT-NA headquarters at 301-589-6062.

FULL-FEATURE PC TERMINAL EMULATOR AVAILABLE
RTP+ is a terminal emulator program written for the application layer of a
packet-radio station. The program has been a labor of love over the past
four years and has evolved into a very sophisticated program. It is an
enhancement of RTP, which itself was developed from PTP with the intention
of simplifying its user interface, while adding several new features. RTP+
runs on an IBM PC, PCjr, XT, AT or PS/2 with a TAPR-compatible TNC or
multimode controller, such as the AEA PK-232, Kantronics KAM or MFJ 1278.
RTP+ requires IBM DOS 2.1 or later and works with the monochrome or CGA
adapter. A minimum of 256 kbyte of RAM is required. The program is not
copyrighted.
RTP+ provides numerous functions and modes for operating packet radio, CW,
AMTOR and RTTY. The program is extremely versatile and fully configurable
from definition files that the user creates. Functions included in this
program are optionally sent connect messages, optional automatic issuance
of commands to the TNC when starting and ending RTP+, optional automatic
enabling of certain features when starting the program, two or three split-
screen modes, a "Net Master" mode for more than two stations in a
packet-radio QSO, optional connect alarm, background and foreground color
selection, optional filtering of monitored BELL characters, optional
receive and transmit anti-word-wrap (no words will be split across lines)
and a quick save capture for both connected and unconnected packets.
The program also features an unattended personal mini-PBBS, choice of two
cursor types (regular or big block for LCD screens), expanded function key
capabilities, support of non-packet-radio modes (CW, AMTOR, RTTY for
intelligent terminal units or multimode controllers), an optional
personalized prompt on the center strip of the split-screen, configurable
NTS traffic handling function and built-in traffic editor, selectable DCD
detection for both TNC 1s and 2s, configurable scroll-back buffer and
optional installation of new SET (TNC parameters) file from within a DEF
file. Function key editing from within RTP+ is supported and all
definition file commands can be edited from within the program. Other
features include user-configurable tags for function keys, optional printer
capture, on-line help, optional saving of scroll-back buffer to a capture
file, receive and send scroll-back buffers, support for escape to DOS and
return, optional communications buffer purge, performance of predefined DOS
functions or commands, automatic sending of NTS traffic to a PBBS,
uploading and downloading in ASCII, XPACKET, XMODEM and binary, recalling
of previous sent lines, type-ahead buffering, a prompting utility to create
DEF files and full dual TNC support via two COM ports. Also, optionally
combined TNC commands in a file can be sent to the TNC,
