My K2 seems to have way too much gain with the preamp on for 30
meters, OR I have a bad EMI problem here. The noise level stays at 10 to 20
over S9 with it on, and it is not useable with the noise floor that high.
With the preamp off, the S-meter seems to sit around S3. Is this normal for

If you turn the preamp off,
The noise you hear floating across the bands - MIGHT- be one
or more ionospheric sounders. These are transmitters that send
high-power signals ... usually straight up ... into the ionosphere.
They usually sweep upward from frequencies below the BC band
into the higher HF regions and can be
