[ale] Any ham radio operators among us? Linux in the shack?

[Allen Beddingfield]

I was wondering if there are any other ham radio operators on the list?  
If so, I'm curious what Linux applications you make use of in the shack for logging, digital modes, or anything else interesting?
Also, problems dealing with RFI from PCs and power supplies?  I've got a fairly new PowerSpec from Microcenter that jumps me from S3 to S9  of noise floor on 20m when switched on (complete with bug zapper-like noise bursts).
