[hpsdr] S meter bug

[Roland ETIENNE]

Hi all, and Doug W5WC,

I have found a little bug with S meter when receiving above 30 MHz. When the
S-meter is displaying S point instead of dBm, I noticed that the display
jump from S4 to S0 when signals are < 124 dBm, and in fact the 20 dB less in
VHF is missing:

 if (num <= -124.0f) output = "    S0);

should be:

 if (num <= -144.0f) output = "    S0);

(in console.cs lines 29288, 30706, 31011, 31226).


Testing a new beacon here on 50 422 MHz was the opportunity to notice this
problem!

73 and thanks for the job on the software, greatly appreciated!
