I did a little more testing with Preview 8 and if I am using VAC (no TX audio chain processing) I get the same power output as Preview 7. Without VAC the output still seem to be down about 40-50%.
Has anyone else noticed this behavior with Preview 8? -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tim Ellison Sent: Monday, December 19, 2005 5:02 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] RF Output down 50% from preview7 I noticed earlier today that my forward power when transmitting on SSB was significantly lower with Preview 8 than with Preview 7. As a test, I ran Preview 7 and tested the RF watts out when I had voice peaks of 0 on the ALC meter. The SDR Forward Power meter showed peaks in the 90 watt range. This was verified on my watt meter as well. I deleted the database from preview 8 and restarted the application. I imported Preview 7's database with out any problems. I verified that the TX settings were the same between the two versions. When testing with Preview 8, the RF power out only registered about 30-40 watts with the exact same ALC values (peaking on 0). My watt meter also showed about a 50% decrease in power. I took great care to keep all the variables the same between the two test cases. I decided to violate Fett's Law so I shut down the radio and did some work that pays the bills and came back later to repeat my experiment. I got the same results. Would there have been an change in the TX audio chain that would have be responsible for this reduction in output power? -Tim --- Tim Ellison <mailto:[EMAIL PROTECTED]> Integrated Technical Services <http://www.itsco.com/> Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell >>> PGP public key available at all public KeyServers <<< _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz
