Re: [Flexradio] Delta 44 & Audio settings in general
Something is definitely not right. Let's simplify things then get complicated. First off, disconnect all outboard hardware. Then set the TX meter to MIC and not ALC in PowerSDR. Then plug the mic directly into the Firebox and while talking in a just above normal voice, set the mic gain on the Firebox until you see the clip light blink. Depending on the mic, you may need to speak loud to get the Firebox preamp to clip. If you can't get it to clip, then add the +12 dB boost on Mic1 from the Firebox control panel. Once you get the pre amp to clip, then back it off a few notches. Connect the rig to a dummy load and/or reduce the wattage to 1-2 watts (to reduce QRM). Set the MIC gain to 5. Turn off the EQ, the COMP and CPDR. Make sure that the TX filter in the TX profile is not set to some ridiculously narrow setting. Click on the MOX and while the TX is engaged and talking, increase the MIC gain until your signal peaks at 0dB. Then turn up the wattage to 100 watts and see what you get out using a peak reading external meter. If it is not peaking reading, you will only see about 15-30 watts output max. If you can't get any output that provides 0 dB on the MIC TX meter, then the next place to start looking is at the cables between the Firebox and the SDR1K. Are you using the Hosa cables? Are you using the 6-pin-to-6pin Firewire cable to get power to the Firebox or the wall wart? I would get this configuration working and then start adding your outboard hardware one piece at a time. Remember if you outboard hardware is line level out, then the input to the Firebox would be line level in (TRS not XLR) 73 de W4TME -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jimmy Jones Sent: Wednesday, May 24, 2006 8:52 PM To: FlexRadio@flex-radio.biz Subject: Re: [Flexradio] Delta 44 & Audio settings in general Brian, My ALC Meter never makes it to zero.

Re: [Flexradio] Delta 44 & Audio settings in general
Brian, Changes surrounding the TX Meter selections have caused some confusion here. The OLD ALC setting (1.4.x and before) is now the MIC setting. It was a tap at the beginning of the DSP chain and had nothing to do with ALC. The NEW ALC setting is a tap at the end of the DSP chain just following the ALC and will give readings that reflect everything before it (such as the compressor, compander, EQ, etc). The correct procedure for calibrating the microphone input on the current software is to use the MIC setting on the TX Meter and target 0dB on peaks. This needs to be reflected in all our documentation. Please let me know if you find places other than the Delta 44 QSG where other methods are mentioned.

Re: [Flexradio] Delta 44 & Audio settings in general
Brian, The MIC meter is before the compressor and the compander in the TX DSP chain. So having these on or not should not affect the input calibration procedure. Make sure that you are using the MIC selection on the meter though and not one of the other selections that are later in the DSP chain. If you are unable to get to 0dB in the MIC meter, then you may need a microphone preamp.
