[hpsdr] High S meter reading on noise floor.

[Ari Thor]

Hi

 

S meter do not change with bandwidth but noise floor get lower with smaller bandwidth ?

So how can S meter give Signal power in bandwidth if I get same S meter reading  in 500 hz or 6000 hz bandwidth ?

Hello Ari,

S-Meter gives the Signal Power in the receiver bandwidth. Panadapter shows power in the bin width.

Hi

 

On 6 meter I have noise floor  -132 dBm      same time Smeter say -114 dBm

and S meter say 5.1      bandwidth is 1.5k

RX1 Meter is set to Sig Avg, I get higher reading with Signal.

Why do S meter not say same reading as Panadapter ?

And how can I have S meter 5  With only noise of -132 dBm ?

And where do Smeter get -113 dBm ?

And why do we have 24 hours in day 😊
