[Icom] PW1 vs 4KL

Wed, 02 Jul 2003 20:32:22 -0400

Malcolm,

Been using my PW-1 (version 2) for past 3+ years and think it's great 
other than the loud fans.  However, I do recall two issues raised on 
this reflector.  First, one ham had some experience running RTTY 
barefoot at 100 watts through his PW-1 only to have a component in the 
amp fry under marginal SWR.  His research indicated that the component 
was significantly under rated even with the amp off.  Not sure how 
this was resoved or the details.  Second, the power supply is integral 
to the amp.  If the PW1 PS fails repair or replacement is expensive.  
Not sure what the case would be with the 4KL given the PS is a 
separate unit, but no longer manufactured.

Anyway some thoughts,

Harry WE1X
