Power Supplies A constant current source source can supply a fixed current to a load regardless of input voltage or load change. The LM is quite useful as a constant current source, works on a wide input voltage range, from 3V up to 40V. The circuit is rather simple, uses only one transistor and few passive components and performs well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation. With 12 volt DC it will deliver 1 watt RF power. The most important parts of the oscillator are the transistor Q1 and the tuned circuit, which comprises the inductor Ll and the variable capacitor CV1. When the battery is first connected, a brief surge of current flows from the collector to the emitter of Q1, causing an oscillating i. An oscillating voltage therefore appears at the junction of Ll and CV1. The frequency of the oscillation depends on the values of Ll and CV1, so that varying the value of CV1 tunes the oscillations to the exact frequency required. In order to achieve a high output level, you will need a well tuned antenna, and a large heatsink to dissipate the heat from T2 transistor. Transmitter was mounted in metal enclosure and works extremely well.

The scale describing wind force devised by Admiral Sir Francis Beaufort in , in which winds are graded by the effect of their force originally, the amount of sail that a fully rigged frigate could carry. Becalm To cut off the wind from a sailing vessel, either by the proximity of land or by another vessel. Becalmed Unable to move due to lack of wind; said of a sailing vessel. Before the mast Literally, the area of a ship before the foremast the forecastle. Most often used to refer to men whose living quarters are located here, officers being quartered in the stern-most areas of the ship near the quarterdeck.

Officer-trainees lived between the two ends of the ship and become known as “midshipmen”. Crew members who started out as seamen, then became midshipmen, and later, officers, were said to have gone from “one end of the ship to the other”. To make fast a line around a fitting, usually a cleat or belaying pin. To secure a climbing person in a similar manner.

An order to halt a current activity or countermand an order prior to execution. Short movable bars of iron or hard wood to which running rigging may be secured, or belayed. Bell A type of buoy with a large bell and hanging hammers that sound by wave action. Below On or into a lower deck, e.

It is science, though many times confused as being the same thing. I’ll prove my point. You know that I could never have been inside of your mysterious building out there, and I imagine you can be sure no one has told me its secrets.

Introduced in , the Collins 51J receiver was intended for the military or commercial users that required an extremely accurate frequency readout and a very stable, drift-free receiver that was especially suited for use in data reception, such as RTTY, but could also provide excellent reproduction of AM or CW signals.

At lunar takeoff, this tanker would mass tons, but since it is taking off in lunar gravity, it would effectively weigh only about 62 tons. The composite propellant tanks, similar to what will be used for the BFR, would probably mass only 20 tons, leaving 2 tons for the engines, 2 tons for the landing legs, and 6 tons for the rest of the structure, including the cryo-coolers, sunshade and power system. This provides a structural mass fraction of 8. At this point, we do not know the actual cost of the lunar propellants as delivered to the tanker at the lunar base, including the vehicle development costs, but finally we can compare the relative mass of the delivery propellants.

Assuming that we have not underestimated the tanker mass, the delivery propellant mass from Earth to LEO to L1 is Note that this mass difference is about three to four times larger than the typical cost difference of 15— Cost of lunar fuel would include fuel production costs, transport propellant costs, and vehicle operation costs. Even the cislunar tanker must undergo an aerocapture to return to LEO from L1, while the lunar-to-L1 tanker would encounter only the stresses of thrust and landings.

In addition, propellant at L1 is at least twice as valuable as propellant in LEO, due to the gravitational potential and additional velocity from an Oberth maneuver performed starting at L1. If future lunar entrepreneurs can beat that price, and if lunar water ice does exist in minable quantities, the lunar fuel production enterprise seems assured. Sales of large amounts of propellant for Mars expeditions would assure a robust human presence on the Moon.

However, to assure that the logistics capability of any cislunar or L1 base will exist, the propellant depot and cargo handling capabilities must be a part of the design of the base from the beginning.

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity.

There are two types of hook-up drawing: Process Hook-Up This hook-up drawing contains typical installations for instrument which connects to the process Pneumatic Hook-Up This hook-up drawing contains typical installations for instrument which requires instrument air such as control valve, actuated valve Reference drawing: A good designer can also read whether the instrument tapped in gas service or liquid service.

On the face, this is not particularly offensive if the class exists primarily within the AMYA. But if 99 percent of class boat owners are not AMYA members, and the class specification is approved by a multi-country class organization — then this practice is divisive. As we all know, there are enough challenges to growing and maintaining an RC sailboat class. It is confusing to newcomers and unnecessarily thumbs-a-nose to larger class organizations.

In the past, AMYA members who own one of these two large classes have not attempted to change the class specifications within AMYA, even though they could. But now, a splinter group from the Nirvana class is proposing to vote on a class specification that is not in compliance with the international class rule that Nirvana follows — and tomorrow, it could be the RC Laser specification coming under attack. We see no positive outcome of such a practice and think AMYA should exempt class specifications from AMYA voting where a superior class rule is in effect.

We are looking for your input on this seemingly unnecessary and class splitting action by AMYA. We encourage you to post your comments to this article. Fold in Your Sail? We get calls frequently about how to take a creases out of an RC Laser sail. Unfortunately, this is nearly impossible to do terry towel over sail with iron set to max steam.

Sometimes we get a little sloppy and the sail gets folded when incorrectly installed in the bag.

Artwork drawing of the 51J-4 from the manual Many Collins Radio enthusiasts believe the 51J Series comprises the best looking receivers that the company produced – but, what about 51J performance? Like many pieces of collectible vintage electronic gear, the 51J receivers are now over half-a-century old. Many users are operating their 51J receivers in “as-found” condition. Are they experiencing all that the 51J is capable of?

Supercardioid Shotgun A microphone’s directionality or polar pattern indicates how sensitive it is to sounds arriving at different angles about its central axis. The polar patterns illustrated above represent the locus of points that produce the same signal level output in the microphone if a given sound pressure level SPL is generated from that point. How the physical body of the microphone is oriented relative to the diagrams depends on the microphone design.

For large-membrane microphones such as in the Oktava pictured above , the upward direction in the polar diagram is usually perpendicular to the microphone body, commonly known as “side fire” or “side address”. Some microphone designs combine several principles in creating the desired polar pattern. Omnidirectional[ edit ] An omnidirectional or nondirectional microphone’s response is generally considered to be a perfect sphere in three dimensions.

In the real world, this is not the case. As with directional microphones, the polar pattern for an “omnidirectional” microphone is a function of frequency.

Pilot Electric Manufacturing Company also claimed to be “The World’s Largest Radio Parts Plant” in the twenties and they did build all of the parts supplied with their kits. Though not the first Shortwave receiver kit offered by Pilot, the three-tube “Wasp” was certainly their first really popular Shortwave receiver kit. The plug-in coils selected the tuning ranges that covered meters to 17 meters or about kc up to

A microphone, colloquially nicknamed mic or mike (/ m aɪ k /), is a transducer that converts sound into an electrical signal.. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, radio and television.

As with directional microphones, the polar pattern for an “omnidirectional” microphone is a function of frequency. The body of the microphone is not infinitely small and, as a consequence, it tends to get in its own way with respect to sounds arriving from the rear, causing a slight flattening of the polar response.

This flattening increases as the diameter of the microphone assuming it’s cylindrical reaches the wavelength of the frequency in question.
