[Elecraft] K2 Audio Hum Problem (60c)

[K9ut at aol.com]

I noticed a severe hum (60cycle) hum in the K2  after testing a Heath  hw101 
.   it appeared that i had damaged the front end of the K2 ,and  after some 
alarm and checking all things i discovered that i had moved a Small  Alarm Clock 
120vac near the K2 and it was causing all the problem . I have  heard about 
similar problems with Power Supplies near the rig but this is a new  one ! It 
sure caused me some grief for awhile (hi)
 
 So keep all ac coils , Xmfrs, clocks ,etc away from the K2 !
