[Elecraft] [Elecraft_K3] K2/K3 Operating Tip: Using SCAN to keep an eye on your favorite (too-quiet) band

[Wayne Burdick]

If there's a high noise floor, try the following, in this order:

- Turn off the preamp, and possibly even turn on the attenuator
   (SCAN is pretty sensitive, so it will stop on real signals above
   the noise floor even with the attenuator on)

- Narrow the filter bandwidth and slow down the scan rate accordingly
   (example: If you set WIDTH to 100 Hz, set RATE to 10 Hz rather than
   50 Hz so you won't miss as many real signals)

- Try backing down RF GAIN a bit

- Use a lower-noise antenna
