In case of reception of a RS ID by the SdR, it is also proposed to jump to the transmission shifting the bandwidth containing the RS ID to the base band. > The MultiDEM program looks very nice.

There is not RS ID decoding in Multidem as it is not the objective of this soft. > 0.0% to 0.1% is really very low. As there is an AGC, the level in the > standard waterfall must be much higher. The problem with very low level depends on the sound card. If down to 10 bits it is only noise (standard sound card), all the signals (in base band) good or not will be mixed with the sound card noise and they will be bad. Now if the first 16 bits are clean of noise (Multipsk SdR working on 16 bits), the signals (in base band) will be good. The best is to have a comfortable global level, so there will be no doubt. 73 Patrick ----- Original Message ----- From: "ed_hekman" <ehek...@cox.net> To: <digitalradio@yahoogroups.com> Sent: Monday, February 15, 2010 6:14 AM Subject: [digitalradio] Re: Amazing !
