Microphones (2021-10-25)<\/h1>\n
By: Dot, AC4HH<\/span><\/p>\nA couple weeks ago Dot, AC4HH, provided another wonderful training session on the YL Net. This one had so much information, I thought we should post her notes for reference. Remember, every week, we have a wonderful Technical Topic and Emergency Preparedness Training on the net, so make sure you join in the fun.<\/p>\n

\n- Ham Radio for Dummies, 3rd Edition, by H. Ward Silver, N0AX<\/li>\n
- ARRL Handbook 2017<\/li>\n
- Several searches on the Internet about microphones and watching a couple of YouTube videos called \u201cHow Radio Microphones Work.\u201d<\/li>\n<\/ul>\n
Like many of us, you may not have given much thought to your microphone. All you do is push the PTT button on the mic and talk. The microphone that came with your radio from the manufacturer is perfectly adequate, right? That\u2019s right. However, occasionally a mic will become noisy or quit working due to a loose wire or something else and will need replacing.<\/p>\n
Some operators just want a mic with improved audio fidelity \u2013 meaning it sounds more like your voice. Net control operators and contesters like the hands-free convenience of a handset with an attached boom mic held in front of the mouth. Hand-held radios are easier to use with a speaker mic attached to the collar, shirt pocket or lapel.
\nA microphone is a transducer that converts sound waves into electrical signals. This means it transforms one type of energy into another. In this case it turns mechanical energy into electrical energy, air sound waves into audio signals.<\/p>\n
Let\u2019s take a few minutes to look at different mics, without brand names or prices, and what makes them work. There are:<\/strong><\/p>\n\n- Manufacturers\u2019 mics that come with the radio<\/li>\n
- Speaker mics you can use with handi-talkies<\/li>\n
- Headset mics<\/li>\n
- Desktop mics<\/li>\n
- Boom mics that can be positioned in front of you and controlled with a foot pedal<\/li>\n
- Wireless mics that have small, battery powered radio transmitters in the microphone<\/li>\n
- Throat mics, which pick up vibrations from your throat. They wrap around from the back of your neck so the transducer ends are snug against your throat, and they do not pick up any acoustical background noise.<\/li>\n<\/ul>\n
Types of Microphones:<\/strong><\/p>\n\n- Ceramic mics vary widely in quality, so a cheap mic is not a good bargain because of its effect on the transmitted power level and generally poor speech quality.<\/li>\n
- A Dynamic mic resembles a small loudspeaker. It converts sound into an electrical signal by means of an electromagnetic principle using a diaphragm attached to a coil of wire. The diaphragm is the portion of the mic that receives the sound waves. It\u2019s the tiny plate that first moves when sound waves hit it. The diaphragm vibrates the coil in response to the sound wave.<\/li>\n
- Electret mics use a piece of special insulator material, such as Teflon. Sound waves modulate the capacitance of the material (that is, the amount of electrical charge) and cause a change in voltage. These mics have been greatly improved in recent years and are used in most cellular headsets and computer headsets.<\/li>\n
- Condenser mics. Condenser mics have a condenser capsule made up of a series of three metal plates\u2014a back plate of brass; another metal plate or sometimes a very, very thin piece of plastic. When you pass voltage (40-80 volts) into the circuit, a plastic diaphragm vibrates when a sound hits it.<\/li>\n
- Ribbon Mics. A ribbon microphone is typically made up of a lighter aluminum ribbon suspended in a voltage field. It has a very low output and is used to record voice and musical instruments.<\/li>\n<\/ul>\n
The frequency response of a microphone can make a big difference on the air. Some transmitters use \u201cspeech processing\u201d, which is essentially a specialized form of speech amplification. As you can see, microphone output levels vary depending on the microphone type.<\/p>\n
In summary, let\u2019s compare the Dynamic mic and the Condenser Mic:<\/strong><\/p>\nA dynamic mic has simple construction with few moving parts, is extremely rugged, and has a lower sensitivity, which means it has a lower output level. Dynamic mics are versatile and ideal for general-purpose use. Dynamic mics are widely used for amateur radio. They are also used by radio broadcast stations because they have a broader sound. Condenser mics are more complex but have a more natural sound and better sensitivity. Of all microphone types, condensers have the widest frequency response. Also, condenser mics usually offer much higher output and lower noise than dynamic mics.<\/p>\n

<\/a>Want to jump in and help?<\/h3>\nWe are always looking for Alternate Net Control operators to help us out on a regular basis, we also need someone to take the Net a few times a year for various reasons!<\/strong><\/p>\nThink about volunteering to be the ANC this week or any week in the future.\u00a0 It is a BIG help to the NC to know that someone else is listening to the check-ins and conversations because, as you have noticed, sometimes the signals are weak or scratchy and it is hard to hear clearly.\u00a0 So the ANC is a BIG help, 4 ears are better than 2.<\/p>\n
What does the Alternate Net Control (ANC) do you ask.\u00a0 Well, you listen to the check-ins and write down their names, call signs, location, how they are coming into the net, etc — just like the NC (Net Control) person is doing. You are a ‘double check’ so to speak.\u00a0 When \/ if the Net Control misses a check in or can’t hear all that the person checking in said, then you serve \/ help as a back up with the information.\u00a0 Finally, at the end of the net, the NC and the ANC compare their numbers of checkins. Usually they both agree. The ANC then emails or texts the list she made to the NC and that’s it.<\/p>\n
It is very unlikely that the ANC has to become the NC, but with the script you will do fine.\u00a0 And not to worry — the NC will not pretend to go off the air just to make you become the NC.<\/p>\n
Usually that is all the ANC has to do — but, if perchance, the radio of the NC goes kerplooie (is there such a word?) and doesn’t transmit or NC has some kind of crisis and can’t transmit, then the ANC takes over till the NC gets back on the air.\u00a0 What do you do while the NC is recovering?\u00a0 Just follow from wherever the NC was on the script.<\/p>\n
