couple of small problems running v2.2.3 (single or dual Rx version)
downloaded from the openhpsdr website with Hermes and that is that
'Alex' is always selected. This means that within the 50MHz band the <span id="yiv657549159misspell-1" class="yiv657549159mark">dBm</span> levels are out by the
gain of the <span id="yiv657549159misspell-2" class="yiv657549159mark">LNA</span> in Alex (26dB?). Tuning just outside the band and all the levels return to normal.</div><div id="yiv657549159yui_3_2_0_18_1350330705177105">Is there a way to deselect Alex properly please? Its <span id="yiv657549159misspell-3" class="yiv657549159mark">unticked</span> in the setup>hardware window, but the button is illuminated on
the main screen (button next to <span id="yiv657549159misspell-4" class="yiv657549159mark">MOX</span> and below TUN).<br>(I also get <span id="yiv657549159misspell-5" class="yiv657549159mark">Metis</span> selected, can't deselect that either??)<br><br>Second
problem - the ADC overload warning comes on fine with the single
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 triggered by the input level exceeding a certain <span id="yiv657549159misspell-6" class="yiv657549159mark">dBFS</span> level determined in software (if so, what is it -1<span id="yiv657549159misspell-7" class="yiv657549159mark">dBFS</span> or 0<span id="yiv657549159misspell-8" class="yiv657549159mark">dBFS</span> etc??)<br>Incidentally,
I notice that there is about as far as I can estimate a -7dB (maybe its
6dB, can't tell) difference between ADC input level (<span id="yiv657549159misspell-9" class="yiv657549159mark">dBFS</span>) and the level indicated on the <span id="yiv657549159misspell-10" class="yiv657549159mark">Powersdr</span> 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 real level etc, but can anyone confirm the
relationship please?<br>Is there any way to observe the actual ADC <span id="yiv657549159misspell-11" class="yiv657549159mark">wideband</span> level in <span id="yiv657549159misspell-12" class="yiv657549159mark">dBFS</span>??<br><br></div><div id="yiv657549159yui_3_2_0_18_1350330705177130">Many thanks,</div>Andrew<br>G4<span id="yiv657549159misspell-13" class="yiv657549159mark">XZL</span></div></body></html>
