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).
