That's great and I like the idea, but with a variable S7 to S9 noise floor here, I find the K3 stops all the time - would you expect that or am I doing something wrong? 73 de M0XDF, K3 #174, P3 #108 -- For all our conceits about being the center of the universe, we live in a routine planet of a

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

You could use the SQL control to set the threshold up to the noise floor. I use scan all the time with an S4 noise level, and the SQL helps a lot. matt W6NIA On Wed, 04 May 2011 16:36:02 +0100, you wrote: That's great and I like the idea, but with a variable S7 to S9 noise floor here, I find
