Hi all,
Been searching the 300 meg range, and stumbled accross this irregular licence.
Licenced to the Department of Defence. The assigned frequency is 361.200 Mhz, but i noticed that
the upper and lower frequencies were so very different, and it turns out that the emission bandwidth allowed is a whopping 51.6 Mhz. Its an Australia Wide, Transmit and Recieve frequency...
Just baffled as to WHAT this is used for and WHY it is one big huge whopping bandwidth.

Thanks Guys
EDIT
Found another one in the 200 Meg range
http://web.acma.gov.au/pls/radcom/assig ... ID=2219327
This one has bandwidth of 32 MHz.. Assigned frequency - 251.000 Mhz
Thanks again

Possibly a huge data transfer frequency, the more data you want to throw in the least amount of time requires more bandwidth.

Re: Millitary "Frequency" - ACMA Search
in this pdf that i use the only people that will know what it is used for is the ADF and even then only a hand full of people will know

Re: Millitary "Frequency" - ACMA Search
Could be used for anything and everything!
Unlike civilian organisations, the ADF have very little outside interference when it come to the way they use their frequency bands, as long as they don’t stray on to Civilian Organisation’s systems they can do near any thing they want – data, voice, video anything basically.
The exception is on the old HF Bands where the ADF are a little sensitive about its use, reason being some radio operators could tune into the ABC Radio to listen to the ABC News while out on exercise, only to accidentally transmit onto the ABC frequency when called by another station/callsign - a big no no

Re: Millitary "Frequency" - ACMA Search
We had that as an example at SES, they were saying that they used to operate on a frequencies that was a little bit out of a millitary one and SES were doing training one day and so was the army.
So the SES operator said something like "Repeat last message" and then there was a loud explosion because apparently repeat in army terms means fire again so therefore they changed it to "Say Again"
Cheers Shane

That is why it got stressed to me during SES training and in ACMA training to never say repeat.Rochedalescan wrote:We had that as an example at SES, they were saying that they used to operate on a frequencies that was a little bit out of a millitary one and SES were doing training one day and so was the army.

Maybe for some spread Spectrum freq hopping satellite use going on there huh??
Australia was using a form of spread spectrum comms for years. The US later adopting the same system
used in the Milsat system
I have a print out of all the freqs and uses for that system. though it's about 10 years old now. But it does make mention of the ultra wide band use
