The power supply is a 6 volt type. A microphone sort control box was alternately out there; that is believed to have been the same management box, merely lacking the handset cradle. Produced at least through 1949. The knobs are the identical as proven on the P-69-12 above. Shown beneath is an unusual, apparently early P-69-18 with a blue nameplate and a handle on the higher cover. A naked minute later, as he drew closer to his prey, Jedburgh was capable of discern that the dirigible’s side was embellished with a great flag - a diagonal blue cross, bespangled with white stars and rimmed with white, on a red floor. Then he aligned a mark on the sights together with his prey, and snapped two of the knife-switches closed directly. For instance, some businesses might need started out with Philco cellular police receivers, after which added Motorola T-69-20A transmitters. "A jury would possibly ask for more proof" stated McBryant. Then he turned as soon as more to his machine. Also included in the SP-1 handbook is an instruction on find out how to wire the squelch to also be controlled by the remote head, the manufacturing facility squelch control on the chassis then being unused.

There have been other antenna designs, which had been unsuccessful, resembling a trombone shaped affair which mounted below the auto running board on the driver's facet, on insulated spacers, or the front bumper getting used as an antenna by completely rubber-insulating it from the rest of the auto chassis. There are 16 diode modules for the receiver and sixteen for the transmitter. As originally configured, the facility supply was normally put in on the firewall of the vehicle, subsequent to the receiver and under the glove box, whereas the RF section was positioned within the trunk and attached to its antenna through a brief braided copper rope. This seems to have been Motorola's only AM cellular transmitter, and is a two piece set in which the facility provide and modulator are in a single case and the RF section in a second. It is also believed that assorted particular versions had been made to buyer order, reminiscent of non-customary power supply inputs, mounting schemes and so forth. The P-69-17 just isn't particularly delicate and with the low power of the companion T69-20A transmitter, range would have been somewhat less than that of a modern CB radio. See typical T69-20A installation photo below. There was additionally a "giant" mobile speaker, featured in the photograph of the transmitter installation proven later on this web page.

The NC Highway Patrol gear was used with a sixteen channel scanning control head as shown beneath. Below is a typical P69-14 management head, somewhat clearly a modified automobile radio management head. The FCC additionally issued an order at the top of the war that each one new police radio programs have been to be on the brand new a hundred and fifty Megacycle band, absent a exhibiting of want to stay on the 30-50 Megacycle band. Link was able to promote portions of his VHF FM police tools based mostly on the Connecticut designs to the military for use in armored autos being shipped to North Africa. A number of the earliest postwar 2-approach California Highway Patrol installations started out with a Police Cruiser receiver, and added both Motorola and RCA 39 Megacycle VHF FM transmitters later, in the case of the RCA by modifying the RCA management head to function the P-69-18 Motorola receiver ! A copper or bronze screen was inserted between the "tar" top and the wood slats of the roof, and the lead-in brought down to the receiver by way of the hollow submit on one facet of the windshield. "Sir," he stated, "I take it that you simply had been the operator of that fowl-machine which brought me down?

"I do not believe I understand you, sir" he mentioned softly. Jedburgh smiled again. "I bought him in the long run," he muttered. The day was three hours older when a call from one of the spotters triggered Jedburgh to show a spy-glass on the northern finish of the sea-loch. Jedburgh turned his gaze after which his spy-glass in the route that he heard known as. At first he noticed nothing, and then a flickering speck within the sky; then, all in a second, he discovered his prey. Then Jedburgh tugged at a launch-rope, removing heavy wooden wedges from underneath his craft, and cast these wedges away. Jedburgh could not restrain a cry of triumph as a scarlet flames bloomed across the gas-bag. Jedburgh gritted his teeth and struggled to hold the sight regular on the gasoline-bag. Although he could not surpass the dirigible, Jedburgh in some way felt that he held the excessive floor. Now Jedburgh may flip his attention as soon as again to his particular job. Looking ahead once more, he realised that the ornithopter had now dived to within a naked hundred toes or so of the gray sea. The ornithopter was now a simple glider, and Jedburgh was able to concentrate on the issue of figuring out which amongst its controls had been not efficient.
