Notes on the 1240 - 1300 Mhz IARU R1 band plan

1. IARU Region 1 bandplan

The following notes are part of the IARU Region 1 bandplan for this band, originally adopted during the IARU Region 1 Conference at Noordwijkerhout (1987), and all member societies should strongly promote adherence to the recommendations made in these notes.

At the IARU Region-1 Conference at Cavtat (2008), Recommendation CT08_C5_27 was adopted which designated the 1240.0-1240.75MHz segment as an alternative narrowband section and makes a series of recommendations for replanning other parts of the band for DATV and Digital Voice & Data


1.1. Footnotes

a. deleted

b. Refer to Beacons chapter for coordination in the beacon sub-band - section 11.

c. In countries where 1298 - 1300 MHz is not allocated to the Amateur Service (e.g. Italy) the FM simplex segment may also be used for digital communications.
 
d. Bandwidth limits according to national regulations.

e. This segment is for simplex use only with no Digital Voice gateways. Embedded data traffic is allowed along with Digital Voice. Digital Voice users should check that the channel is not in use by other modes.

2. Usage

The following note refers to the Usage column in the bandplan. As already set out in the introduction to section IIc, in the right amateur spirit operators should take notice of these agreements which are made for operating convenience, but no right to reserved frequencies can be derived from a mention in the Usage column.

2.1. General

During contests and bandopenings local traffic using narrow-band modes should operate between 1296.500 - 1296.800 MHz.
