[Elecraft] 2nd Report

[Drew AF2Z]

No KPA1500 here but I did replace the fans on my lil' ol KPA3 with 
Noctuas. They are noticeably quieter. If there is a suitable Noctua 
replacement for the KPA1500 fans you might want to compare the sound 
level specs to the Sanyo Denkis.

Wonder if it would be possible to build an active noise cancelling 
system into the rig itself; seems like it would work in that enclosed 
space...

73,
