Hello Bill,


0 dBm is far too much for me and some others.

The old WSPR versions go down to - 30 dBm







On LF and ELF not the transmitting power but the radiated power (ERP) is 
entered and especially on ELF ERP powers below 0 dBm are more common than 
higher powers ;i)

Hi Group,



during tests with FST4W and very low power ( 25µW) I noticed that power < 1 mW 
cannot be set in the GUI.

That was different in the past. I just checked, even in WSPR-X, you could set 
the power down to - 30 dBm.

This should be taken into account in a final version.

Hi Joe,

the range of power levels in the FST4W message are the same as for WSPR, that 
is 0 dBm through 60 dBm in steps of 3 ⅓ dB (the numbers shown in the user 
interface are rounded to whole dBm).
