The major disadvantage of the system is that it did not indicate the aircraft's location within the beam, unlike a pulsed system where pulse timing can be used to determine range.

After McCabe made use of the " confidential recipient " system to express his concerns, his district superior ordered him to cease use of the Garda Pulse system on 14 December 2012.

While work by Shembel and Bonch-Bruyevich on continuous-wave systems was taking place at NII-9, Oshehepkov at the SKB and V . V . Tsimbalin of Ioffe s LPTI were pursuing a pulsed system.

As a result, modern markers now feature Empire's Reloader B2 and MagnaDrive, Dye's Rotor, ViewLoader's VLocity, Odyssey's Halo, The Q-Loader and the Draxxus Pulse systems, each feeding at rates of 22 balls-per-second or more.

David realized the advantages of a pulsed system, and in October 1938 he designed a 50 MHz, pulse-modulated system with a peak-pulse power of 12 kW . This was built by the firm SADIR.

On 30 December, two senior officers officially traveled from Westmeath to his house in Cavan, an unheard of event in the force, to tell him they were restricting his access to the Pulse system.

They co-opted Oshchepkov's pulsed system, and by July 1938, had a fixed-position, bistatic experimental array that detected an aircraft at 30-km range at heights of 500 m, and at 95-km range for targets at 7.5 km altitude.

For this reason the twelve-pulse system has become standard on almost all line-commutated converter HVDC systems, although HVDC systems built with mercury arc valves usually allowed for temporary operation with one of the two six-pulse groups bypassed.

At the SCB, Oshchepkov worked with scientists at the Leningrad Physico-Technical Institute ( LPTI ) on a pulsed system, the first in the USSR . His work was closely followed by Abram Ioffe, Scientific Director of the LPTI and generally considered the leading physicist at that time in the nation.
