I am on travel and unable to load SSDR 1.0 at this time. With Preview 16 I still needed Comp to get audio to drive RF power with configuration above. If anyone has been able to configure SignaLink with rear Accessory jack, using DIGI(U)L, no EQ, no Comp, please share!

I am a far better critical care cardiologist than technical radio buff!

I am in your boat.... Comp needs to be on to get enough drive.

SignaLink jp4 jumpered. Windows mixer (usb codec) set to max. 15pin connector used for ACC input.
using WSJT-X for JT65, Pressing the tune on WSJT application, I can dial up to 100 watts out using tx control on siganlink. Using FLDIGI can get up to 80 watts out doing the same thing. (I never use over 30 watts in those modes).
Comp OFF No EQ

One thing to note, the windows mixer setting for the application being used (fldigi for example) may not show in the mixer window until "tune" on the application is pressed at least once!

I was having the same experience until a day or 2 ago. I have it working now without Comp on. After a bit of troubleshooting, I found that I *had not* seated the JP3 jumper that increases the Drive to the ACC connector. All was well after seating JP3 correctly.

Sorry, Brad's right, it's JP3!

I am setting JP3, no COMP, turn off RX and TX equalizers, and bump the power up to 60.
(And don't forget to select ACC)

Still no joy with out Comp

Without JP3 - Windows USB codec speaker device at 100, Flex power slider 100, ACC, No Comp, RX & TX Eq off, Signalink TX max -- fldigi tune power unreadable on Flex power out

With JP3 - Windows USB codec speaker device at 100, Flex power slider 100, ACC, No Comp, RX & TX Eq off, Signalink TX max -- fldigi tune power ~10w on Flex power out

With JP3 - Windows USB device at 100, Flex power slider 100, ACC, Comp 50, Signalink TX adjustable -- fldigi tune power adjustable on Flex power out 0 to ~100

I'm sticking with Comp on

When you first open the windows mixer and select speaker device (USB Codec) you will see nothing under the "applications" section of the mixer window. If fldigi is running, and you hit the "tune" button in fldigi, a new slider will appear marked "fldigi" on the application side of the mixer window (at least in windows 7). You must crank the fldigi slider to max, and it should retain that setting the next time you transmit from within fldigi. It works the same for other applications using the USB codec.

I don't know. You're doing everything right. Perhaps you should put up a suggestion for an input +20db selection for the audio input (similar to the mic +20 db) that could be implemented on the ACC input. That may help until they finish the DAX interface.

Have you tried leaving the TX EQ on and pushing all the sliders to the top?

Just as I expected the TX eq (+10db across the board) accomplishes the same thing as COMP (at 50).

This past weekend I operated the WW DX RTTY contest with just cables between the 6700 and the sound card.

- Splitter cable to take line out from the 6700 to line in on the sound card
- Line Out (powered speaker output L/R) from the sound card to the ACC input

Provided adequate drive with COMP OFF - level meter showing peak just at 0 - the measuring bar (red line) a few dB lower.

If I used an isolation transformer like the in my Rig Blaster, I couldn't get enough audio drive via the ACC connector.

Without isolation, the built in sound card in the computer gave a residual hum level of transmit at -95 dB - with the USB sound card/stick I have (ASUS X3), the residual hum level is -105 dB.
