Thom and the group,

I have had a terrible noise on 40m for quite a while and I thought (big 
mistake) it was really band noise. 

Last Thursday evening just before the Fox hunt, I decided to really 
determine if it was band noise or "in the house" noise.

The CFL's, computer, and computer monitor were fine.  The last thing I 
powered off was the brick power supply for an external IDE hard drive 
that I use for backups.  The +20 noise dropped to nothing.  Plugging it 
back in produced the +20 noise again.  My K2 with the KDSP2 sounds 
better now than it has sounded in a long while. 

I never realized just how noisy those small devices are.  Hope this 
helps someone else....

Regards & 73
