Choke filters work well in applications where the load current is 
constant - such as RTTY, AM linear and FM.  With SSB, where the load 
current is not constant,  a choke filter causes a transient V regulation 
problem.  To observe this problem, one needs a DC 'scope.  A 
resonant-choke filter works well for SSB.
