1. Project Description:
Approximately three months of on-the-air tests will be conducted
to determine host well the AS-12 operates, what ionospheric phenomena
permit or prevent it from working, what changes should be included
in future units,and what are the best procedures for operating the
AS-12.

One day of the schedule (26 September) Was lost becauz'e of minor
equipment fail-Lire. It was noticed that the message preambles as
received at the base wore greatly foreshortened. The field sot was,
therefore, returned to Buffalo on 2i- Septem.-acr. A i onostable cir-
cuit in the field set reccivcr-exciter delays message transi'!ission
for 300 milliseconds to prevent transmission during the base sounding
period. A capacitor lead in the monostable had broken, resulting
in "early" transmission (that is, before the base is prepared to
listen).
One failure also occurred at the base. A diode shorted in the
interference detection receiver second I.P. As a result we were
sounding on channels that may have been too noisy for message reception.
This may have caused a lower ratio of message confirms to trans-
missions than that of which the system is capable.
The tests have been running extremely well from the standpoint
of equipment perforr.ance. Nature, however, has not been as kind.
Solar disturbances and electromagnetic storms seem to be norrial
conditions. For several test days we have been "wiped out"
completely. Of course, it is interesting to observe system operation
(or failure) during these unusual conditions, but we have had more
than our share.
