[Elecraft] KPA 500 Fan Noise

[Toby Pennington]

I have had the amp now about a year.  

The cooling fan is just fine when using SSB,   but when on cw and running a while at full output,   the fan comes on and sounds like it is going to take off from the table.  It is really loud

I have the fan speed set to 1,   but wonder what others are doing to quieten the fan a little bit,   or what fan speed you have the amp set to.  OR WHATEVER >    Toby  W4CAK
