ARLS007 ISS Packet System is Back on VHF
The Amateur
Radio on the International Space Station (ARISS) packet
digipeater system is
again operating on VHF - 145.825 MHz. The
failure of an Ericsson handheld VHF
transceiver on board the ISS
last fall had caused ARISS to shift packet
operation to 70
centimeters. A cargo resupply mission in February delivered a
new
Ericsson 2 meter handheld, to replace the one that had failed,
which
had been used in the Columbus module for school group contacts
and
for Amateur Radio packet.
While the VHF transceiver was offline,
ARISS shifted school contacts
from NA1SS to the Kenwood TM-D710 transceiver
in the Russian Service
Module. NASA ISS Ham Project Coordinator Kenneth
Ransom, N5VHO, said
the VHF capability now back in Columbus can be used in
conjunction
with passes involving the HamTV digital amateur television
(DATV)
system, which operates on 2.4 GHz.
ARISS International Chair
Frank Bauer, KA3HDO, said recently that
ARISS continues to make progress on
the development of the new
interoperable radio system on the ISS "that we
hope to use to
replace our aging radio infrastructure in the Columbus module
and
the Service module."
Packets digipeated in a valid APRS format via
the ISS system and
picked up by an Internet gateway station are documented on
