W4ZV> On 10 meters it may be 2-3 uV and on 160 it will seldom be
below 20-30 uV and may reach as high as the maximum 192 uV on an
extremely noisy night (storm QRN).

This empirical data nicely ilustrates natural noise level on 160 m being
some 20 dB above higher bands and redundancy of preamps on modern <uV
sensitive radios!  It also shows low RX dynamic requirements for Top band
:-)
