Summer of 1941 first test via Google Earth

The notables during the summer of 1941 first test:

The first test were to see if the signals were stable.  They noted the higher frequencies were more stable in the daytime and the lower ones were more stable at night.

Reception was as far away as Springfield, MO.Montauk station to Springfiled was about 1175 miles and the Fenwick station to Springfield was about 1000 miles.

The monitor at Manhawkin, NJ only reported on signal quality, by phone.  They did not synchronize the transmissions.

They noted that using a circular sweep scope was awkward, if not impractical.

In the late summer,  A.J. Touch of the British Air Command visited the Radiation Lab.  He described the GEE system in a cursory manner.  He also assured MIT that accurate measurements to better than one microsecond was possible with portable equipment.  He also hinted that a multiple trace indicator can provide a means to match pulses on delayed sweeps.
