I'm going to get my license soon as well as my first equipment. I wanted to know if anyone had recommendations for equipment. I wanted to have good equipment for all three types, regular radio, voice, and data. Especially data transmission. I got some ideas in my head for You may as well start learning the lingo. The FCC has codes, like A0,A1,... for amplitude modulated schemes including CW and AM, and F0,F1,... (I think) for frequency modulated schemes. I suppose there are various others. I have not really used them but they are good to know when reading the regulations. Hams use more informal terms. My usage is no doubt quite dated, but these are some that come to mind: CW (continuous wave, but keyed on and off) Basic Morse code AM (amplitude modulation) Voice - ancient style SSB (single sideband (suppressed carrier assumed)) Voice - newer style DSM (double sideband, suppressed carrier) Rare. AM sans carrier FM (frequency modulation) NBFM (narrow band FM) RTTY (radioteletype, generally using FSK) FSK (frequency shift keying, think FM equivalent of CW, also used for data) Some others, most of which I have no experience with: PSK Phase shift keying PSK31 A PSK system used for chat and a basis for various digital modes MST3K 0k - not a modulation scheme - just wanted to keep you awake SSTV Slow scan television various digital modes?? Basically, you use CW,AM,SSB, RTTY/FSK, and PSK31 on the HF bands, and maybe NBFM. You use various modes above 30 Mhz, but voice is typically FM and Morse is often, if used at all, sent via FSK, maybe via sound card feed into a microphone input. Digital modes I'll leave to you to investigate, but looks like people like to use sound cards to avoid requiring anything special on the transmitter and receiver other than CW and SSB capabilities. George rigging a data transmission but I'm thinking that there might be hardware for data transmission already so I don't have to get hacky with it. |
