Eric and Tim; Okay. I've got it working now. The modes have to be switched between digital and voice modes in order to get the VAC to automatically disable. Checking the AutoEnable box while remaining in a voice mode doesn't automatically cause the VAC to disable; you have to cycle the modes.
Interesting........ Somewhere, though, I've seen a short description of how each of the audio gains are setup. There are a RX and TX Gain adjustments on the Audio/VAC tab; there is a Transmit Compression FeedForward adjustment and a Compand adjustment on the Transmit tab. I don't think I imagined it; somewhere I saw a set of steps to set these adjustments using the multimeter. Thanks a million, both of you for helping me with the VAC problem.

Do this. Put the radio in one of the DIGI modes. Open up setup and check both boxes in the VAC setup. Click on Apply. With the Setup screen still open, click on a SSB mode. You should see the enable check box (the one at the top) go unchecked. Check voice mode to see if your mic is working. -Tim --- Integrated Technical Services "You can't close the door when the walls cave in" --Robert Hunter -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ken Klein Sent: Thursday, April 06, 2006 6:14 PM To: [EMAIL PROTECTED]; FlexRadio@flex-radio.biz Subject: Re: [Flexradio] transmit audio` Eric; Hate to say this, but the AutoEnable checkbox on my system doesn't work like that. Voice modes work fine if VAC isn't checked; won't work if it is not, regardless of the state of the AutoEnable checkbox. The voice information I'm looking for is a description of how to set the compander and compression and what to expect from the meter in each of the meter modes; ALC, ALC Comp; CPDR, COMP, Lev gain, Leveler, and EQ. I know I've seen it somewhere! Thanks for the help!

VAC will be disabled in all other modes when AutoEnable is on. The calibration for the transmit chain is the same as that stated in the Delta 44 and FireBox Quick Start Guides. Namely, click the MOX button and watch the TX Meter set to the MIC setting. Adjust your input until your peaks are just under 0dB. That is the optimal setting.
