fm is the primary close range mode for 10m amature use. cw is morse code. am is not used on 10m (bandwith restrictions)

you are using it on 11m cb i presume, am and ssb are what you will be using. fm is good if others have exports like you. (its illegal but so is your radio)

Not quite true. AM can be used anywhere SSB can.The restriction is PHONE not bandwidth. AM is narrower than FM. There is a lot of AM on 10m between 29.0 and 29.2 when the band is open.

In Europe we also have some repeaters which opens at 10meter in FM mode.
Some thimes it is better range of FM than AM, it depends on the conditions. If you run 50w FM on a flat countryside you cant say its short range communnication. On 1w FM mode with a good antennasystem and good positions my record is 49km.

The closest of my locals position is 26.3 km from me. I run daily 4w FM and the reports are R5 S6.

We use only FM mostly because of bigger interference problems with the AM mode.
