Here is another test. Using the directions in the Operating Manual, test the output voltage from the sound card and see if it matches the voltage setup for the D44 sound card.
Also try grounding the breakout box (if you are using it) to the shack ground. -Tim ----- Integrated Technical Services -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Anderson Sent: Sunday, January 28, 2007 10:26 AM To: k5nu; FlexRadio@flex-radio.biz Subject: Re: [Flexradio] sdr swr Mike, Here's an experiment to try: unplug, at the SDR, the audio cable from the PC's Line-Out to the SDR (this is the TX audio signal). Now click on TUNE. What happens? (With no TUNE audio, power out should be 0 watts). - Jeff, K6JCA -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of k5nu Sent: Sunday, January 28, 2007 5:08 AM To: FlexRadio@flex-radio.biz Subject: [Flexradio] sdr swr A question for the group. On the "transmit" tab I have the Tune set to Zero. I still have 35w output as I click the Tune button. Is that normal? Also on my external wattmeter, the power out in the "Tune" position, is very unstable. It will "flutter" back and forth by as much as 25-30 watts. This makes it very difficult to tune an amp. With the power out jumping around. etc. All calibrations have been done in the method suggested by various sdr users here on the reflector. My patience is wearing very thin. 73, Mike K5NU -------------- next part -------------- An HTML attachment was scrubbed...
