"Development of technique and equipment for providing day-time service equal in radius to night-time service by use of a single high frequency...status: investigation of E-layer day-time transmission of high frequency has been completed and the use of a frequency of approximately 10.5 mcs. authorized. It is the opinion of Radiation Laboratory that this frequency will give a satisfactory day-time range of service from 800 to 1,300 miles although it is expected that the 10.5 mcs. signals will be some what weaker that 2 mc. signals. A program to obtain and modify transmitters and start a service test on this frequency will be started in the near future."

The experiments that had been in progress for some time in the Laboratory to develop an automatic synchronizer seemed also to begin bearing fruit as about this time one was developed which did not deviate nor lose control through high noise levels including electrical storms. Four of these units were being built by the laboratory and by July so confident were they of the worth of the auto-sync that the Laboratory placed an order for sixty of these units based on their prototype to be delivered around the end of 1943.|a7=Its important to note at this time that the work on the radio navigation project referred to as Project #3 or (Project C) undertaken by MIT did not take place at the famous "Radiation Laboratory" which remains the place where radar / microwave was born. Instead, the engineering team assigned to work on radio navigation moved into the Hood Building in Cambridge, close to but outside the MIT campus.

Instead, the project engineering team worked in the Hood Building in Cambridge, close to but off  the MIT campus.  Further research will be carried out to locate this building. Rad Lab was awarded an IEEE Milestone  ..........
