Single Sideband
Phone transmissions include AM, FM and SSB, USB upper side band is commonly used for 10-, 12-, 15-, and 2-meter radiotelephony transmissions, LSB lower side band is used on 40-, 80- and 160-meters, Radioteletrempe : Narrow band direct printing telegraphy emissions,
Fast Scan Television : 6 MHz
For FM the modulation index is the ratio between maximum deviated signal and maximum modulated frequency Most analog radios have a 300 Hz to 3000 Hz passband For ±5 kHz deviation you a modulation index of 1,67 For ±25 kHz deviation your modulation index is only 0,83,
Top responsesIf I want to fit an FM signal within a specific bandwidth, should I limit the volume or the audio spectrum? Since you gratificationed Carson’s rule, I’m going to … read more3 votesTo limit the bandwidth on FM you have to limit the deviation, If you want to fit two FM channels into a 25kHz spacing you limit them to 12,5kHz deviation,1 voteIt looks like it depends on your stockage, If you reduce the input bandwidth, your speech will be muddled, If you reduce deviation, your modulation index will go … read more1 voteI know you said you’re in AUS, but here in the US we have restrictions on incident regardless of bandwidth, The table §97,305 Authorized emission trempes says for … read more1 votePlacardr tout

So when you listen to FM 99,1 on your radio, your radio only pays exclusivité to 200 KHz of bandwidth centered at the frequency of 99,1, Radios are built to handle multiple bands, bandwidths and frequencies, You’ve probably seen radios that combine AM, FM and shortwave, Let’s have another look at our RTL-SDR screen,

· If your deviation is in the 2-3 KHz area you will occupy 16kHz bandwidth now referred to as narrow FM Now a days wide / narrow transmitter deviation is usually a software selectable option, The quote/unquote standard for ham radio has been 5KHz max deviation/20kHz bandwidth,

The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use, The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz,

What is the bandwidth of FM and AM radio?
· Notice that FM consumes the widest band of frequencies and is variable from roughly 5 kHz to 15 kHz, The FM bandwidth varies with the power or ‘loudness’ of the voice audio prosauvaged,
· I’m an Amateur Radio enthusiast, I love the hobby and experimenting with radios, antennas and software, On my YouTube channel I upload perduos on the Icom 7300 and Icom 7610 along with Ham radio software programs, I hope to inspire people to try new things in Amateur Radio,
· AC0FP Ham Member QRZ Chérubin K7JEM said: ↑ The FCC assigns 16 KHz as the bandwidth of +-5 KHz deviated FM, and 11,25KHz as the bandwidth of +-2,5KHz deviation, Don’t know where that 7,5KHz figure is coming from, it’s not tolérable,

· Ham radio operators still use normal FM mainly because they were not required by government regulators to change to narrowband, and regular FM continues to work well for them, MURS radios can still use regular FM only on MURS channel 4 and MURS channel 5, GMRS can use normal FM, but most of the so-called GMRS bubble pack radios are now using NFM,
