[amsat-bb] NF Trimming.

[Terry Carrell <TDCarrell@xxxxxxxxxxxxxx>]

Hi, Has anyone got a design for a simple better/worse noise 
generator that can give usable results at 2.4GHz? 
Or perhaps a link to a source? 
Just something to ensure improvements improve.

Built the "$2" signal source using 80MHz TTL osc ex-486 MB 
and a 1N4148 multiplier - now I cannot live without it!

The "Paper Helical" - mine's 12 turn on the centre roll of a 
plastic food bag dispenser - works like a charm. (Now adding
another roll to make 24 turns for a bit more gain.)

73, Terry, ZL3QL.
