[Elecraft] Excellent External Speaker for K2

[DW Holtman]

Hello,

I finished my base K2 about a week ago. I installed the Noise blanker and 
SSB modules, with no problems. Next I installed the DSP module. The audio 
quality went to Sh**. I spent two days playing around with filter 
adjustments, DSP settings to no avail. Tonight I plugged in an external 
speaker. Magic!! The distortion is gone, it sounds great. For some reason I 
was using a headset until I put in the DSP module.

The internal speaker on the K2 is so bad, it is almost unusable. Unless the 
one I have is defective. I have been having it sit side by side with my 
TR-7, wondering why I ever bought a K2. Now with a working speaker, I know 
why I bought a K2. It really is a very nice receiver.

Best,
DW Holtman
