John, Maybe it's -110 dBm average noise, but with -20 dBm static crashes? Normally you would see these as broad lighter areas on the waterfall, short duration.
You may also have a noise source that's peaking high, but outside of the P3's visible span range. If it's anywhere near 40m, the P3 would still pick it up and it might cause the detector to disable the preamp. I've had this happen with SWBC signals on voice peaks. This (or some similar cause) could explain why you have this happening only on 40m. 73, matt W6NIA On Sat, 22 Mar 2014 07:04:59 -0700 (PDT), you wrote: >On further investigation it appears to only happen on 40 meters and I >discovered I had the preamp on.
