If you record using the USB the recording is made digitally. Then there should not be more noice if you use a software to raise the altitude.

If the recorded altitude level is to low, you can use programs like Cool Edit Pro to raise the altitude.

Fred, you can try recording using jack to jack wires, from line out onyour KN7000 and to your PC sound card. Recording will now be analog but the ticks will be gone. Cool Edit Pro will work fine for this recording.
