Hi Rupert.

There was a big discussion on the BB about a week ago. There maybe some good tips there. Mails are available at

S Band uplink will need a little work but X-Band is available 'off the shelf'

I've attached an article on a suitable LNB, its performance and how it can be modified to make it's stability a little less temperature dependant.

Hi Guys,

Just read some interesting info from the Amsat-DL FB site about uplink / downlink frequencies

for the P4A satellite due to launch end of the year / early next year.

My quick query was around what sort of station (transceiver / receiver / transmitter) will be

needed to work this satellite, will this be with off the shelf kit or will up / downconverters

be needed...?

Also the X & S Band LNB needed to support this sat, are these freely commercially available..?

Thanks for any tips / help here...

Cheers
