She discusses hams' place in the army and civil protection in the course of global warfare II and the chilly battle in addition to the influence of the pastime on relations dynamics. by way of contemplating ham radio within the context of different technical hobbies--model construction, images, high-fidelity audio, and related rest pursuits--Haring highlights the shared stories of technical hobbyists.

This is now done by means of-a remote control tuning arrangement. Work is now in process on the production of a new control unit, C-85/APT-3, to replace the existing remote control and afford operation directly from the panel of the transmitter. Higher output can be obtained by use of Power Amplifier AM-14/APT with this set. Antennas used with this equipment are quarterwave stub antennas, AT-37/APT and AT-38/APT, and are mounted 45 degrees from the vertical to jam sta- tions polarized other than vertically.

The transmitter is continuously tunable in ilight, if necessary, over the complete frequency band. Two tuning adjustments are necessary. In ordinary use the transmitter frequency will probably be set on the ground and three or four sets staggered to cover the entire band. c. source. The power input of 1500 watts produces an output of 200 watts over the frequency range. The transmitted signal is a random noise modulated signal designed to jam the enemy signal in the frequency range of the transmitter.
