- Voice Of America- the "propaganda" arm of the US Govt.
-

-
- Nope. I think VOR is "Vector Over Radio" for pilots
-

-
- Legend has it that it is a slang from the Brits: "Allo! Didja 'ear
- that Colin got 'is 'amater ticket? Ya' 'e's an 'am now!" And from
- there came "ham" ar amateur radio.

- > What is "BFO to hear SSB voice and CW (code)"?
-
- Radio uses the heterodyne difference between a carrier frequency
- and another frequency to make the sound. It takes two frequencies
- to make it work. Both SSB and CW have only one frequency (CW only
- carrier, SSB only the second frequency) In order to hear either,
- a second frequency needs to be inserted. That's what the BFO does.
- Its full name is "Beat Frequency Occillator" It inserts a frequency
- for the signal to "beat" against, hence, making it audible.
-
- > Why are some frequencies called 'meter', as in 10meter band?
-
- This is the distance between the "humps" in the wavelength. 10 meters=
- 10 meters between "humps". This is the "old" way of referring to
- frequency and is a holdover from the "old days". The 10 meter band
- is from 28.0 mHz to 29.9 mHz

- No problem. A good resource for this kind of thing is the ARRl Handbook
- and the ARRL Operator's Manual. One or the other of these books should
- be available at a public library. The World Radio and TV Handbook
- (WRTH) would be handy for this kind of info (and other info also)
- and any good bookstore can order it if it doesn't have it in stock.
