[amsat-bb] AO40 5.6GHz uplink?

["Murray Peterson VK2KGM" <vk2kgm@xxxxxxxxxxx>]

Hi Graham,
                    These PAs sound similar to the ones supply by Mini-Kits
in Australia.

http://homepages.picknowl.com.au/vk5eme/minikits/Kits2.html

These ones are 10 watts on FM but 8 watts SSB to avoid non-linearity. They
want about $400 Australian dollars for them which is about $200 USA dollars
and a bit over 100 pounds sterling.

Regards,
Murray Peterson
