Redirected to the SAREX group.  I do not agree with all of these point,
however, No standing program should be de funded to do these. Get another
satellite up ASAP is AMSAT's main goal.

Subject: [amsat-bb] A Proposal for ARISS

After posting some thoughts a few days ago (RE: ISS, what the heck
happened?), I have given the idea more consideration.

Proposal (ARISS on ISS):
1)  Install a 100-KHz transponder unit on ISS, with usual digital
2)  It would run mode-UV
3)  Installed internally in the ISS
4)  Replace most of the current ISS ham radio equipment
5)  Could be considered an upgrade/improvement to the existing ham radio on
6)  Use ISS power and existing ham radio antenna infrastructure (no solar
panels)(no thermal requirements for space environ)(perhaps less radiation
7)  Use batteries for stand-alone operation (recharged from ISS power)
8)  Control commanded from ground (no intervention required by astronauts)
9)  Local access for use of astronaut-hams
10)  Provide emergency back-up comms for ISS (perhaps with a separate FM
11)  (perhaps) Use of existing ham-radio handheld on ISS on low-power to
dedicated receiver which would activate astronaut repeater channel.
12)  This FM channel could be used as FM ham repeater when not in use by
astronauts  (means world-wide monitoring for the astronauts as well as
normal Leo FM activity)
13)  Modular design for future upgrades and/or repair (easy installation by
14)  Segmented pass-band to allow packet/APRS digipeating
15)  Transmitters able to be shut down for eva and other critical missions
either locally on ISS or from ground.
16)  Perhaps a special Rx/Tx on ISS eva channel for cross-band repeat in
event of loss of atmosphere emergency (help to sell the concept to NASA as a
comms back-up).
17)  No need for orientation (spin or de-spin), rad hardening, thermal
structures (air-cooled), no propulsion, no launch requirements.
18)  Easily maintained by supply from ground (repairs or upgrades).
19)  Long-Life

Re-direct of either Fox or P3E efforts?  (no launch requirement-rides as
cargo to ISS)
