Judging  at the number of emails that I have received concerning the location of
the LSB filter in the PRC-47 AMPL MOD module. I have posted a photo at the link
shown below.
As Mike says    "A picture is worth a thousand words."
It is important to try and keep both filters on  the module board and construct
the  leads to the relay  as short as possible due to obvious problems with RF
and hum and as I have posted previously  you will probably need to do an
alignment of the module using  either a factory or homebrew module extender
system. Obviously if you locate the additional filter outside of the module and
hard wire it some where  on the chassis  this can not be accomplished and this
procedure lends itself to picking up hum and having a possible  "unbalanced
module situation" etc.  And yes the module cover will
have to be bent slightly to accommodate the new filter.
I will try and get more details posted in the future but for now here are the
Before and After pictures.
