I used several SDR programs, KGSDR, Spectravue, HDSDR, and SDR-Radio.com. First of all, only KDSDR will currently direct tune the radio. Also set the IQ Offset to around +8 on the DJ-x11 or none of the programs may decode a signal. If you use SDR-Radio.com be sure to set Swap IQ signals setting to on, or USB and LSB will be reversed.
Remark 1
I haven't checked this, but I will.
Remark 2
This is in VFO mode. I suspect this not uncommon to only catch only strong signals that only open the squelch at this speed.
Remark 3
If you are referring to the Fcount / Ftune feature be sure to take a look at the 1,2,3 settings for it. I find that on the 3 setting Fcount / Ftune works about the same as my Uniden scanner.
As far as audio goes its not bad. I would say it is a bit on the wide side, which makes it pleasant for FM and AM broadcast as well as AM airband. It does get a little more thinner sounding on NFM frequencies. You do have a little adjustment with the highpass and lowpass settings. The highpass setting does help to remove some of the hiss from NFM. You also don't have tons of loudness, but it is more than adequate for indoor listening. You probably wouldn't hear it that well on your belt at a very noisy site. You don't get the nice beefy audio as say from the Wouxun 2 meter HT, which is built like a commercial radio.
Hope this helps
In order to use the IQ Offset function, you need to have a firmware version
2.10 or above. The latest firmware version is 2.60.There is a PDF file on the Alinco DJ-X11 firmware page with the exact information you need.
DJ-X11
Once you are at the page, look for the link just after or under the line "[Instruction Manual Update]" This will look like the word "here" underlined.
The setting is found in the "Receiver" settings group. Select "IQ Output" and select enable. The default shift is 0Khz and is adjustable from -24 Khz to +24 Khz.
I hope this is useful to you.

Detected signal output function
Some digital signals, such as 9600 bps high-speed packet communication of amateur radio, use modulation methods called FSK or GMSK. Conse- quently, these signals cannot be received properly with the DJ-X11 which receives filtered audio signals such as 1200 bps AFSK packets. In such a case, you may be able to receive data communication by inputting the signals to a dedicated connecting device (TNC, etc.) or a PC.
IQ signal output function
The DJ-X11 can output IQ signals from the earphone jack. By connecting the earphone jack and the PC's MIC/LINE IN input port with a commer- cially-available cable with ø3.5 mm stereo mini-plugs on both ends (the specification is the same as the cable used for the Cable-clone function described on P. 98), you can use SDR (Software Defined Radio) pro- grams to enjoy reception on the PC using software available on the Inter- net. Since some of these programs offer functions which are unavailable with the DJ-X11 such as DSP (Digital Signal Processor), this function will expand the fun of "watching".
