New Zealand video downlinks
 

Hi there,
I am trying to confirm / find out a couple of things.
1. What is the video downlink frequency from the NZ police auckland
helicopter (eagle) - is it 2.7GHz?
2. I am told this is a standard unencrypted video signal, is this correct?
3. Apparently the audio channel trnsmits gps information of the helicopter.
Has anyone tried to decode this?

Thanks
John Burns

I've have this secondhand, so can't 100% confirm myself.

According to a source the NZ Police HeliTele links are somewhere in
the 1.8-2.0Ghz range. I know someone using an Icom ICR-9000 and he
reckons he can rx them.

Is there any way to confirm this?
I have access to a spectrum analyzer which goes up to 2.050GHz which I may
have to keep at the ready on my desk at work for when the chopper flies
over.........

I cant seem to see a carrier except for the usual vodafone stuff at 1810MHz.
The spectrum analyzer I'm using goes up to 2150MHz.

Any other ideas?
Can anyone think of a cheap way of getting 2.7GHz? I've been told something
about a MMDS downconverter - does anyone know where I could get one from??

Thanks
