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

Hi Jim, I'm using a Kenwood SP-230 speaker with my K2. It also has the
audio filters and does a great job with the K2.

After replacing the phone jack on my K2, I have been searching for a
really
good external speaker. One that allows me to use my headphones and mute
the
speaker when doing so. Well, I had an old Kenwood SP-180 speaker that I
had
replaced a bad speaker in with a 4 ohm speaker designed for Collins.
This
particular equipment has audio filters and accepts a 1/4 inch stereo
headphone jack. I cleaned it up and it has been in line now for over an
hour. The audio filters really help with CW in QRN and smooth out really
strong signals that otherwise had a harsh note as they were tuned across.
P49V is on 40 meters and is about 40 over S9 and is smooth as silk. The
1/4
inch headphone jack will help, too, as that is what is on the K3 I have
ordered (due in early July).
I just wanted to pass this along as one can find the old Kenwood speakers
for nearly nothing online or at hamfests and they will help K2 audio.
