Wayne and all:  Sky noise using a 630m inverted-L is -120 dBm at best 
and more often -115 dBm so K3 Rx is satisfactory at 630m with stock 
KBPF3.  I also use a SDR-IQ that has a MDS of -132 dBm which measures 
-115 dBm noise floor from the inverted-L.  Use of Beverage antennas 
or Loop antennas can provide lower noise floors depending on your 
location (southern latitudes are noisier due to lightening activity).
