df071c3398 New ECN about clock circuit of atusd boards. Measured (absence of) effect of
adding an inductor to the clock line.

- ecn/INDEX, ecn/ecn0005.txt: new ECN discussing the switch to a
  capacitative clock voltage divider. With frequency measurements.
- atusd/tests/send-20100910: measurement of transceiver performance when
  placing an inductor in the 16 MHz clock line.

b32827dc7e Oops. The atusb boards are of course 20100813. 20100902 was the first
(failed) attempt to make an atusd board.

0a0a50d73d Performance comparison of atusb vs. atusd.
- atusd/tests/send-20100909: conducted performance comparison of atusb vs.
  atusd
- atusd/ERRATA: changed also first board to capacitative divider
