The best way for kids to learn to read and spell is to learn how to separate and combine sounds in words. In this activity, your child will learn to use objects to visually represent the sounds in words.
three sounds: bus – /b/u/s/ bed – /b/e/d/ fish – /f/i/sh/ web – /w/e/b/ bath – /b/a/th/
four sounds steak – /s/t/a/k/ truck – /t/r/u/k/ block – /b/l/o/k/ brush – /b/r/u/sh/ skate – /s/k/a/t/
Step 1: Set the index card, counters, and one of the pictures on the table in front of your child.
Step 2: Say the word for the thing and ask your child to tell you how many sounds are in it.
You might say: “Listen. (bus) How many sounds are in the word (bus)? Let’s say it slowly. /b/u/s/.”
Step 3: Tell your child, “Put a counter in one of the boxes on your card for every sound you hear.” ”.
Step 4: Have your kid count the discs to see how many sounds are in the word.
Put a picture on the floor or table in front of your child if they can’t blend the sounds in the word. One sound at a time, you say each letter in the word and put a counter on the card for each one.
Invite your child to guess which word you are saying. “Listen. /b/u/s/ What’s the word? That’s right! (bus). Count the pennies to find out how many sounds are in (bus). ”.
Choose a picture randomly from one of your child’s favorite picture books. Be sure that the word has just three to five sounds. Say each sound in the word, one sound at a time. Then have your child find the picture that goes with the word you said. Have him then tell you how many sounds he heard.
For example, you might say: “I am looking at the /f/i/sh/. Touch the picture of /f/i/sh/. ” See if he can tell you how many sounds are in the word.
Ham radio also known as amateur radio is a popular hobby that allows operators to communicate with each other locally and globally. But for beginners, all the sounds and signals can be overwhelming. How many different sounds are there in ham radio? What do they all mean? This guide breaks it down into simple terms.
Ham radio uses a variety of analog and digital signals to convey information. While Morse code was once predominant, most ham communications today use single sideband (SSB) voice transmissions. However many other modulation modes are still actively used. Let’s explore some of the most common “sounds” you’ll encounter in amateur radio.
Morse Code
Morse code transmits letters, numbers and punctuation as a series of short and long audio tones, dots and dashes. An operator keys code using a straight key, paddle or electronic keyer. Code readers interpret the modulated continuous waves by ear.
Morse remains popular for weak signal work. It has advantages over voice modes, especially under poor conditions. International regulations protect Morse bands from encroachment by other modes.
Learning Morse code is easier today with apps, websites and audio training aids. Achieving 13 words per minute proficiency is required for higher-class ham licenses. While not mandatory, code skills improve proficiency.
Voice Modes
Voice modes like SSB (single sideband) and FM (frequency modulation) are the predominant ham radio signals today. SSB is used for long distance communications while FM is popular for local repeater networks.
With SSB, operators use a microphone to modulate signals on one sideband of the carrier wave. SSB bandwidth is narrower than other voice modes, an advantage for crowded bands. But it requires precise tuning and a stable signal.
FM modulation commonly supports local VHF and UHF repeater networks. FM bandwidth is wider but it resists interference and fading. HT handhelds typically support FM only while base stations include SSB.
Digital Modes
Digital modes convert signals into discrete on-off pulses rather than continuous waves. Text, data files, images and even video can be transmitted digitally.
Popular modes like RTTY and PSK31 use phase-shift keying to vary the signal phase. Operators use keyboards versus mics. Data speed and error correction varies.
Newer modes like DSTAR and Yaesu System Fusion transmit voice digitally. Most support automatic repeater linking and data services. Digital voice provides features like call signs and messaging.
Image Signals
Slow scan TV (SSTV) and radio facsimile (HF FAX) are two ham radio image modes. SSTV converts images into audio tones similar to analog TV broadcasts.special transceivers display these images on CRT displays.
HF FAX allows transmitting weather charts, news photos and documents over HF bands. HF FAX predated commercial fax machines. Modern software converts images into HF FAX signals.
Control Signals
Some ham signals convey remote control commands versus content. Amateur satellites and moon bounce (EME) systems often use 2 meter CW offset tones for Doppler shift compensation and antenna pointing. Specific tone sequences command rotator movement.
APRS packet networks mark GPS locations using short bursts on specific frequencies. Tracking software decodes these brief “pings” into position data. Similarly, CW or FSK beacons transmit call signs, grid squares, telemetry or messages at set intervals.
Soundcard Modes
Many digital modes utilize PC sound cards with special software. Modulation and decoding occur in software, minimizing Radio hardware. Examples include Hellschreiber which uses FSK signaling to “print” text on special displays. MFSK modes like Olivia transmit text and email at low SNRs.
Soundcard modes now number in the dozens. New variants emerge as programmers create increasingly specialized applications. Their low cost and small footprint fuels experimentation.
Analogue vs. Digital
As you can see, ham radio uses both analogue modes like AM and SSB and digital modes transmitted serially. Each approach has advantages and disadvantages. For example, while analogue voice is intuitive, it requires a relatively wide slice of spectrum. Digital modes concentrate information into narrower bandwidths trading complexity for efficiency.
Understanding the different ham radio transmission types allows making an informed choice for specific operators’ needs. There is no single “best” mode. Hams can smoothly transition between CW Morse, crisp SSB and reliable FM signals as conditions and preferences dictate. This versatility is a key attraction of amateur radio as a hobby.
Getting Started With Ham Radio Sounds
For newcomers, the variety of ham radio signals can seem overwhelming. How do you listen to these signals? And how do you get on the air? Here are some tips:
-
Get a multi-mode receiver – Choose a starter radio covering key analog voice modes plus AM, FM and CW reception. Major ham brands offer entry-level radios.
-
Listen to activity – Set aside 15-30 minutes daily to scan different ham bands and modes. Take notes on active frequencies and operators heard.
-
Learn the lingo – Ham radio has a unique vocabulary. Listen for terms like CQ (calling any station), 73 (best regards) and QSL (reception acknowledgment). There are websites and books explaining ham terminology.
-
Consider digital software – Explore free software like WSJT-X and FLDigi for receiving and transmitting digital modes without buying new gear. Use your current radio with these powerful apps.
-
Study for licenses – Getting licensed unlocks transmitting privileges. Tech license study covers radio technology basics. Local clubs offer exam sessions and ham courses.
Start by listening and learning the ham radio language. Be patient in understanding the different analog and digital signals. With time and practice, it will all begin to make sense! Enjoy the fascinating sounds of ham radio.

What band does a ham radio use?
630 Meter ranges from 472 KHz to 479 KHz. 160 Meter ranges from 1.800 MHz to 2.000 MHz.160 was previously the lowest band used in ham radio and is often called the “top band’ by many hams. HF bands are where the majority of long-distance communications happen in amateur radio. 80 Meter ranges from 3.5 MHz to 4.0 MHz.
What is a ham radio frequency?
A good place to begin is 146.520, the National Simplex Calling Frequency. It’s meant to be a starting point for hams that are not sure what frequency to use. Simplex means radio-to-radio communications without involving a repeater, and it is the simplest means of communicating using amateur radio. What are the Most Common Ham Radio Frequencies?
Is Ham Voice SSB?
(See the AM Phone page .) Nevertheless, most ham voice activity on HF has moved to SSB (see below). Digital Voice is a new technique built around analog to digital converters and codecs that sample a voice signal, compress it, and transmit it as a bit stream.
What frequency is 40 Meter ham radio?
There are currently only 5 frequencies in 60 Meter that are open to ham radio: 5332 KHz, 5348 KHz, 5358.5 KHz, 5373 KHz, and 5405 KHz. 40 Meter ranges from 7.000 MHz to 7.300 MHz. It is considered by many to be the most reliable long-distance (DX) band, and for that reason often has a lot of traffic. 40 is used to transmit CW, voice, and images.
