intership

While there is much experimental work yet to be done before the present system is reliable for intership communication, or before any two systems can work within the same field without each rendering the other useless, such progress has been made by the Government experimenters that, with no interference by private systems, stations can be successfully operated over at least 150 miles of coast line, and they are now in operation on the North Carolina and Virginia coasts, and soon will be instituted between the Farallone Islands and the mainland and Tatoosh Island and the mainland, on the Pacific coast.

VHF channels 2 and 5 are intership channels comparable to channel 40 and intended to be used in the same manner, but for distances of less than 50 miles.

It may occasionally be necessary to call a vessel on channel 16 but the message should be passed on an intership channel.

Though some repositioning was performed during the dual-Doppler scanning, Mirai tended not to move around as much as the Thompson. Moreover, due to the 360° FOV, ship heading did not affect scanning coverage. The above approach enabled the two vessels to perform coordinated scanning by just sticking to the agreed-upon update cycle, which was negotiated prior to the operations period, with relatively little intership communication required.
