Notes:
The expression "Digimode (packet preferred)" means preferred areas of activity for packet radio operations. Where several modes are shown in the sub-bands the first has priority. But this has to be exercised on a Non-Interference Basis (NIB) according to the ITU Radio Regulations. A mode written in brackets ( ) means "preferred area of activity".
Remarks:
The expression RTTY shall be replaced by the expression DIGIMODE. The expression "digimode" includes all modes of this form of transmission (RTTY, Packet Radio etc.). The expression "phone" includes all modes of this form of transmission. Up to 10 MHz LSB and above USB should be used on HF bands.
1.8 MHz band.
Those societies which have an existing SSB allocation below 1840 kHz may continue to use it. However, they are requested to take all necessary steps with their licensing Administrations to adjust the phone allocations in accordance with the Region 1 Band Plan.
The band segment 1907.5 to 1912.5 kHz (Japanese DX window) should be kept free for transmissions by Region 1 stations. Instead use the split-frequency technique when operating here.
3.5 MHz band.
Intercontinental operation should be given priority in the 3500 - 3510 kHz and 3775 - 3800 kHz band segments.
Member Societies should approach their national telecommunications authorities and ask them not to allocate frequencies to other than amateur stations in the band segment that IARU has assigned to intercontinental long distance (DX) traffic, i.e. 3500 - 3510 and 3775 - 3800 kHz.
Contest Preferred Segments.
7 MHz band.
The use of Packet Radio is discouraged on 7 MHz band.
The band segment 7035 - 7045 kHz may be used for store-and-forward traffic in the area of Africa south of the equator during local daylight hours. However, the use of more efficient modes than the AX.25 packet radio are encouraged.
10 MHz band.
The use of Packet Radio is discouraged on 10 MHz band.
It is recommended that unmanned stations using digital modes shall avoid the use of the 10 MHz band.
SSB may be used during emergencies involving the immediate safety of life and property and only by stations actually involved in the handling of emergency traffic.
The band sgment 10.120 to 10.140 MHz may be used for SSB transmissions in the area of Africa south of the equator during local daylight hours.
News bulletins on any mode should not be transmitted on the 10 MHz band.
14 MHz band.
The band segment 14.089 - 14.099 MHz should be used for non-automatic digimode transmissions. The band segment 14.101 - 14.112 MHz should be used for store-and-forward traffic. However, the use of more efficient modes than the AX.25 should be encouraged.
SSTV/FAX: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 portion of the band.
