<p class=MsoNormal>I finally had time to get my HPSDR rig on the air! I’m
absolutely delighted with the receiver and I’m now working the kinks out
of transmit. In running sideband, I have a slight echo on my transmitted
(and monitored) signal, i.e., the “concert hall” effect.<o:p></o:p></p>

<p class=MsoNormal>PowerSDR v1.19.3.1<o:p></o:p></p>
<p class=MsoNormal>I have tried BOTH a computer with Windows XP/32bit and a computer
with Windows 7/64-bit. The same effect exists on both.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I thought at one point it might be an RF feedback
problem. However, I now think not. I can hear the effect on monitor
even with the drive level reduced to zero. I believe the effect is the
same independent of drive level (it’s difficult to tell for sure when I’m
monitoring my own speech).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve tried a couple different microphones that I use
on my Yaesu rig. The effect exists on HPSDR but not on the Yaesu.
So, I don’t think it’s an acoustic effect in the room.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Have I missed something in the settings, jumpers, or
whatever? Any ideas?<o:p></o:p></p>
