Re: [Flexradio] PowerSDR Beta 1.3.13 Released

Ken, Gary, I turned the equalizer on and levelled out the power settings and it now behaves like it should. I need to experiment with the Mic In Gain on the Audio Tab in setup so that I can find a happy medium between voice and psk. 73, Dale AA5XE [EMAIL PROTECTED] wrote: Thanks, Ken.  Actually, I found that I had the equalizer on.  The transmit filter is 150-3000, so its OK.  Turning the equalizer off made it behave better.  I probably used different PSK offset frequencies in the different bands resulting in the variation.  Also, I note that CPDR really  has to be turned off.  Setting it to zero and leaving it on makes the IMD poor.  This in response to what Dale suggested earlier.   I can see that digital modes will now require a bit more care in level setting.  There are many ways to screw it up. ;->   Gary AI4IN -------------- Original message from Ken N9VV <[EMAIL PROTECTED]>: -------------- > Dale, go to your TRANSMIT setting TAB and check > the values you have for the HIGH and LOW cutoff > of your TRANSMIT AUDIO FILTER. > de Ken > > > Dale Richardson wrote: > > My observations concerning psk operation with version 1.3.13.
