Re: [amsat-bb] AIDC 3733 Stub

Doug,

You are correct about where to put the attenuation, these guys have a lot of 
gain at the IF.  However, there are some out there that don't feel 
comfortable working on the downconverters with the very small components.  My 
information is mainly to reassure them that not cutting the stub will not 
degrade their reception at 2401 MHZ.  An unmodified downconverter works a lot 
better than a dead one.

If one feels qualified, then cutting the stub should be done, plus adding 
attenuation in front of the receiver.  The picture Mark Hammond posted is 
very clear on where to cut it.  I definitely recommend cutting it with a very 
small pair of cutters, I don't recommend unsoldering it anymore.
