ARDC has now given 110k to ARISS.
Thank you for spotting and disseminating the grant to this list Bryan,
Hopefully, going forward, (members of) the board will proactively copy
information to the 44net list as a matter of routine course. In the
mean-time it's really useful to have these updates. Thank you.
Spent a bit of time reading and learning of the "Interoperable Radio
System" as a result!...
ARISS / Interoperable Radio System:
===================================
Each unit will consist of a Kenwood TM-D710GA radio (separate "head"
and "black box"), plus a custom-developed power supply, able to run
off all of the assortment of power supply voltages found on the ISS
(Russian, and US segments), whilst meeting the EMC requirements (and
not backfeeding RF into the power system!). Each unit looks like:

The units are being developed to fly on the International Space
Station (ISS) in future:

As of 2017 the expected price for the programme had been, $150,000, so
the injection of $110,000 via ARDC is the vast majority. Other
contributions were obtained via:

The existing Ham-band external antenna groups will continue to be
used with the new hardware.

For those interested, $110k ~= a /19 or 8192 IPv4 addresses.
