Just so you guys know....the MHW ProRace 4096 USB adaptor, comes with software that can also internally reduce the jitter...uses a 40MHz 16 bit chip to do it...it also stores your settings so you can jump from PC to PC if you want.
When using DSC, I have also noticed the quality of connections also effects the jitter...so I have to do my best soldering.
Also notice with my 40 MHz testing, that having the tranny aerial down and up also makes a difference. 2.4 is ok.
The software also has a 'check jitter level' in it so you don't have to use the dxtweek...you can change the filter and check the jitter...change the filter again and check jitter again...until you get the best setting.

Here is the manual for it

What are your tricks to minimize the jitter, did you put away the receiver ?
My computer is in a corner of concrete walls and I use FM... some positions of the receiver/radio then give extreme jitter... and I had to use a 'docking station' too... it's easyer to move a 'box', the antenna still right... so the 'docking station' help much to reduce jitter too.

Giovanni, I was not aware this makes a difference..I moved my "docking station" around the area and wow..Now with almost no jitter on FM! Thank you!
Minimizes my jitter, Compromising st/th % ..Open dxtweak, On transmitter knobs/buttons st/trim & th/trim, Align the "direct input" black arrows with the "raw" red arrows. On Y Axis adjust / fine tune in small increments the % of throttle/brake while minimizing the jitter..X Axis to adjust steering %.

Thanks Giovanni for the input, I used this mainly for older transmitters that have limited options, expo, dualrates..Can view the raw data in dxtweak, adjust my rates, and minimize the jitter to a minimum

This soft was presented in tips in the early VRC-PRO when there was no calibration tools in the program, and lot of people were not sure of the calibration... now it has not so much utility as VRC-PRO is with calibration tools... But Graham still using it to check the stability of signal for example.
Thank you for the X64 link and the "run as admin" tip... both go together, as x64 OS is now always with UAC and system tweak always need now admin privileges...
