[Elecraft] STEREO SPEAKER OUT

[Wayne Burdick]

Richard,

The K3's external speaker output requires a stereo plug. Also set  
CONFIG:SPKRS to 2.

Hum pickup is a very common problem with some powered speakers,  
regardless of what they're used with. You may be able to fix it with  
different cabling, moving the DC adapter, etc.

I recommend using non-powered speakers with the K3. It has plenty of  
drive, and this eliminates a few variables caused by powered speakers.

The speakers I use are from Best Buy: "Insignia, 4-inch, 3-way  
surround speakers"; same as the KLH Model 970A or other similar  
models. They're very inexpensive and sound great. Size: about 4"W x  
8"H x 4"D.

73,
