[Paul Bicknell]

Dear all

Could any one let me have there experience with using the 
ADRAT 4110 Frequency difference multiplier

It dues the same as the  TRACOR 527 except it works 
On any of the following frequencies  1 , 2 , 2.5 , 5 , & 10 Mhz

Making it a very useful item in the Lab / work shop 

Also looking for a PDF of the Service manual
