Eric please read my post again you'll see that all your questions have been answered. And the drive is set to 100. The one item I didn't mention is I'm using v1.8.0. ----- Original Message ----- From: Eric Wachsmann<mailto:[EMAIL PROTECTED]> To: 'Myrlen Smith'<mailto:[EMAIL PROTECTED]> ; 'FlexRadio'<mailto:FlexRadio@flex-radio.biz> Sent: Thursday, March 15, 2007 5:11 PM Subject: RE: [Flexradio] SDR drive power
What soundcard are you using? If using the Delta 44, it could be that you don't have enough Signal to Noise on the mic input. What does the Mic setting on the TX Meter read when you are transmitting. It should be peaking around 0dB to get full output. Also, make sure that your drive is set to 100 and that you have calibrated the PA on the band on which you are transmitting.
