[Premium-Rx] Sub-Octave Filters for RA3701

[Ian Ropper]

Hi,

I have a couple of S-O Filter modules for the 3701 and notice a sizeable
drop in signal strength when the module is enabled in the 3701.

Bot modules exhibit the same drop . the attenuator in each unit is set to
0dB.

 

Does anyone know the exact details on these units?

 

Cheers,
