The 20 dB BOOST check box is for mic input only, not the LINE IN path.</div><div><br></div><div>Now, that's no problem at all as you can easily set your LINE IN path to provide 20 dB boost if you wish. </div><div><br></div><div>Do this: </div><div><br></div><div>1) In Setup > Transmit > in Mic box set Max: 30 and Min: 0, select LINE IN</div><div><br></div><div>This will set the range of your MIC slider control on the front panel for a minimum of 0 dB (no gain, no attenuation) and the maximum of the slider to 30 dB gain. </div><div><br></div><div>2) Set the front panel slider to indicate 20 (20 dB gain). </div><div><br></div><div>3) Now if you put a 2 V pk-pk audio signal (0.707 V RMS) at 1 KHz on pin 2 of the DB-25 connector on Penny, you will obtain full rf power out to the output level at which you have your Drive setting set. </div><div><br></div><div>To answer your question of how I check out the LINE IN functionality, I use an oscilloscope to monitor the audio level at pin 2 of the DB-25 connector on Penny and simultaneously monitor the rf power output of Penny. </div><div><br></div><div>This should fix you up. </div><div><br></div><div>From Tokio's message to Phil today it appears he, too, is having some trouble understanding how things are now set up. When using Metis, PowerSDR does NOT use any I2C commands from initozy11.bat...in fact, there are now no I2C commands in that file any more. Tokio, if you read this, please refer to my posting yesterday explaining how this work with LINE IN in the latest software. If you need more explanation contact me and I'll be happy to explain further for you. </div><div><br></div><div>Let me know how you fare, Kurt. </div><div><br></div><div>73, Joe K5SO</div><div><br></div><div><br></div><div><br><div><div>On Mar 10, 2011, at 8:09 AM, Kurt Tausch wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">***** High Performance Software Defined Radio Discussion List *****<br><br> <div bgcolor="#ffffff"> <div><font size="2" face="Arial">Hi Joe, all,</font></div> <div><font size="2" face="Arial"></font> </div> <div><font size="2" face="Arial">thank you for your detailed description.</font></div> <div><font size="2" face="Arial"></font> </div> <div><font size="2" face="Arial">Everysthing is true, when I use diversity18 and have the 20dB Mic Boost ( Mic Preamp Gain ) aktivatet.
