Wes,
The most common cause is that the SSB IF filters are not aligned
correctly. Use Spectrogram for a visual indication of the filter
passband. See
http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf. You
will not be disappointed.
If you need Spectrogram, go to my website ww
I have a very nice K2 that I bought as previously owned. It works fine on
SSB on
20 Meters. The audio from the radio's speaker is low frequency for voice.
Sounds good on CW to me, but the SSB tone/pitch is like there is a LP
filter cutting off the
high frequencies. When I have this situation wit
Thanks Sverre, Mike and Don.
Doh!
After cutting the PC's software gain control to near-minimum, it does
appear that most if not all of the odd-harmonic distortion was due
to overdriving the soundcard. To make certain, I will repeat the
experiment on a USB sound card that has bona fide line inp
Ken,
I do not believe that harmonic distortion is coming from the K2 - that
pattern looks like a soundcard overdriven condition to me.
When you reduce the AF Gain at the K2, you reduce the input to the sound
card, and at some point, the soundcard no longer distorts.
Use the PC soundcard mixer co

Just a few questions to understa
I have been thinking that the receive audio from my K2 (#4314) was just
OK, especially on CW when compared to other rigs including a Drake R8
and a K1. It's not terrible by any means, just not as good as it might
be.
