Equipment

Related wiki pages: Transceivers, Receivers, Radio/PC Interfaces

Most HF transceivers cover some combination of 10 metres through 160 metres; in some cases, equipment from 11 metre (27 MHz) CB radio has also been modified for use on 28 MHz. The expansion of the US 11-metre CB spectrum from twenty-three channels to forty in the 1970's had left large quantities of equipment newly-obsolete and available at a very nominal cost to would-be ham experimenters.

Single-band transceivers are also readily available for the 10-metre band, as are mobiles with both 10 metre and VHF coverage.

Modulation

Related wiki pages: Modes

10 metres had been a common choice for mobile operation, although decreasing costs for 2 metre equipment has displaced much mobile and portable activity to FM on that band. The 10 metre band is the lowest in frequency to permit both FM operation and the deployment of repeater stations. SSB and CW are also commonly used in the lower portion of the band.

Propagation

Related wiki pages: Propagation

Propagation tends to be unpredictable; while most often local stations would be heard, the maximum usable frequency tends to increase during periods of high sunspot activity and at some times skywave propagation over substantial distances becomes possible. More rarely, the maximum usable frequency may be pushed as high as the low-VHF range.
