[Elecraft] [K2] KAT100 + KPA100 power supply in EC2

[Don Wilhelm]

  Werner,

 From prior photos that I have seen, you have great milling 
capabilities, but the KPA100 speaker is exposed through the heatsink (no 
need for any milling).  The only problem for using the KPA100 speaker is 
that you have to run a separate cable for the speaker (and provide an 
input to the EC2).  Most just ignore the KPA100 speaker and use the 
speaker in the K2 QRP cover.

OTOH, if you want a front firing speaker, and are willing to use another 
EC2 enclosure, the SP2 speaker project (that never made production) is 
detailed on the Elecraft website.

73,
Don W3FPR
