I wonder if the 1.66m^2 is the solar array?That would give ~330w of power.The other item is that the statement about 2 arrays (radio), is that 1 array for ground link and the other for sat to sat? Or 2 arrays, an up and downlink simplifying the receiver / transmitter arrangement?
Does the Ettus referred to in the filing refer to https://www.ettus.com/ ?
They will use some fairly off the shelf radios, but the final birds will be far more advanced and will almost certainly contain a huge amount of custom equipment.
The U.S. regulatory decision that denied protected status to satellite systems that have been investing in Ka-band spectrum, and cast doubt about the viability for satellite systems of other slices radio spectrum, has been met with a curiously muted response by the satellite sector.

To update, over the last two months, SpaceX's Seattle office appears to have grown about 15%, with almost all of that growth from mid-March to Mid-April. At least 91 employees.SpaceX's web site shows about 55 positions open in the Seattle office, so for sure they are hiring (with some of those 55 positions maybe already filled and part of the 91+ employee figure, above).SpaceX's Irvine office still seems very small. Unclear from overall LinkedIn search whether it has even been opened. But I note that SpaceX's web site shows a handful of positions open at the Irvine office.

SpaceX keeps constellation options open. 2 sats-inclination 86.6°, circular 625km orbit-get US FCC regs approval; must launch by Aug 2018.
We will also retain the current bond amounts of $3 million for GSO system licenses and $5 million for NGSO system licenses as the final payment amounts potentially due under the escalating bond. We will not adopt SpaceX's suggestion to create a separate bond category for “NGSO broadband satellite systems.”
Most commenters on the issue oppose any increase in the bond amountsabove current levels. 208 Two parties, however, advocate increasing the bond amounts in some fashion. 209Supporting an escalating bond requirement, Boeing suggests that the bond start at a value of $1 million,and increase by $1 million each year if the licensee does not demonstrate compliance with optionalinterim milestones. 210 SpaceX proposes a scaled bond approach for “NGSO broadband satellite systems”that varies by the size of the system: $5 million for systems of 1-99 satellites; $10 million for systems of100-999 satellites; and an additional $5 million for each additional 1,000 satellites. 211 Intelsat opposesreducing the initial bond payment amount for GSO system licensees from the current $3 million value,arguing that doing so could permit entities to obtain a license that are unable or unwilling to construct,launch, and operate the proposed satellite. 212
Perhaps not on the top of the SpaceX building due to the solar farm already up there?

Or 2 arrays, an up and downlink simplifying the receiver / transmitter arrangement?It's talking about 2 solar arrays. Attachement 7 is an analysis of debris risk and how long the satellites will stay in orbit. Solar array area looks to be 6x0.4=2.4m^2. Huge difference in time to deorbit if the solar arrays fail to deploy (39 years instead of eight). Also said these test satellites won't have propulsion or pressure vessels. Attachment 7 can be found on this page: https://apps.fcc.gov/oetcf/els/reports/ViewExhibitReport.cfm?id_file_num=0356-EX-PL-2015&application_seq=66082. (Some of the "Informal Objection" documents are a hoot.)
I didn't read anything about the imagers before. Sounds like a fancy description of a gopro to be honest..

Jeff Foust@jeff_foustMusk: we do have plans for a satellite constellation that could help to fund Mars; now is not the time to talk about it. #IAC2016[/.quote]
