Hermes<br><br>Hi,<br>A couple of small problems running v2.2.3 (single or dual Rx version)<br>downloaded from the openhpsdr website with Hermes and that is that 'Alex' is<br>always selected. This means that within the 50MHz band the dBm levels are<br>out by the gain of the LNA in Alex (26dB?). Tuning just outside the band and<br>all the levels return to normal.<br>Is there a way to deselect Alex properly please? Its unticked in the<br>setup>hardware window, but the button is illuminated on the main screen<br>(button next to MOX and below TUN).<br>(I also get Metis selected, can't deselect that either??)<br><br>Second problem - the ADC overload warning comes on fine with the single<br>receiver version but does seem to function with the dual receiver version???<br><br>What triggers the overload warning, is it the actual ADC overflow output or<br>triggered by the input level exceeding a certain dBFS level determined in<br>software (if so, what is it
-1dBFS or 0dBFS etc??)<br>Incidentally, I notice that there is about as far as I can estimate a -7dB<br>(maybe its 6dB, can't tell) difference between ADC input level (dBFS) and<br>the level indicated on the Powersdr s meter set to read ADC level.<br>I can guess why this might be i.e. each I/Q being 6dB lower than the ADC<br>real level etc, but can anyone confirm the relationship please?<br>Is there any way to observe the actual ADC wideband level in dBFS??<br>Many thanks,<br>Andrew<br>G4XZL<br><br><br><br> </div> </div> </div></body></html>
