10 Mhz Band Plan Notes:

The 10MHz band is allocated to the Amateur Service on a secondary basis only.

Likewise this band is not to be used for contests or news bulletins.

Notes on the HF Band Plans

1.

The expression 'phone' includes all permitted forms of telephony.

2.

If transmitting very close to a band edge, take care not to radiate outside of the band.

3.

Before transmitting, all operators shoud check that the frequency is not already occupied. The normal advice is to use the phrase "Is this frequency in use?" on SSB or "QRL?" on CW

4.

Digimodes are defined as including AmTOR, PacTOR, Clover, ASCII, RTTY(baudot) and AX25 packet

5.

The LSB is recommended on bands below 10MHz, and USB is recommended on bands above 10MHz.

6.

The Region 1 IARU HF band plans are designed to enable the best utilisation of the HF spectrum available.

They achieve this objective because the vast majority of licensed amateurs observe the voluntary recommendations.

In some countries (eg the USA) licence regulations require that specific modes be confined to specific sections of each band.

7.

The frequencies 14.230, 21.340 and 28.680 MHz should be used as calling frequencies for SSTV and fax operators.

After having established contact they should move to another free frequency within the telephony section of the band.
