Dear Sir/Madam


I write with reference to your Draft Five Year Spectrum Outlook, published recently.

The Radio Amateur Society of Australia (RASA) offers the following comments.

Amateur usage of 1875 to 2000 kHz

We request that consultation be undertaken with the existing user with a view to a secondary allocation, if possible.

Secondary allocation at 5.3 MHz

Our view is that there is very little potential for disruption to Defence systems by amateur operation in the segment granted at the WRC (5351.5-5366.5 kHz).

The segment is only 15 kHz wide and is shared with land mobile services.

Moreover, Defence have many other allocations in this part of the spectrum.

RASA have analysed the band in question, using data from RADCOM.  It would be possible to create an allocation of approximately 13 kHz for amateurs if sharing with three commercial assignments could be accommodated.

Given the isolated locations of these commercial assignments, sharing should present few problems.

There is an existing shared amateur-commercial assignment at 5355 kHz.  This has been allocated since 2007, and no problems have been reported to date.

We therefore request that this matter be expedited.


Yours faithfully

(original signed)
