Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hi Procyon12/All, I can confirm that the LED end calibration increases as the USB traffic increases using the little scroll bars. The start point is unchanged (zero on my camera). Here are my readings: (16bit, 1x1, 640x480) USBtraffic/Start/End: 0/0/4500, 3/0/5500, 5/0/6000, 10/0/7500 (SC 3.1.5143) ...

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Dear All, I find these controls rather non-intuitive. What figures should i be comparing in the screen shots? Please could someone provide a guide to the whole calibration process with annotated diagrams. I would like to understand what is being discussed, and to do the calibration myself. Hopefully...

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Hi Niko, Thanks for this useful information: You wrote earlier... " Tim - what DCF 77 receiver do you use? 'Normal' DCF receivers cannot deliver a precise signal: The necessarily very narrow bandwidth of the receiver causes a sometimes considerable delay of the output pulse. (We have 77.5kHz......

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

Thanks, I see the LED light now. :D I followed some instructions supplied on the CD that came with the camera "174m_gps_manual.pdf" dated 25.02.2019. Not a clear translation, and concluded i would set the values back to their default. It looks to me the values are saved in each setting fil...

Re: QHY 174 GPS Calibration LED issue // USB Traffic weirdness

I have set USB traffic set to Zero and im not investigation its effect. Using an LED pulse from a DCF77 receiver (not decoder) I get a 20ms delay in UT when running at 400 fps. Are there any instructions on using the internal LED pulse calibration? I dont see the test LED at all, even on high gain. ...

Re: Norton antivirus stops Sharpcap web page

McAfee BT-net-protect also warns of virus/malware after scanning the download, but I have ignored the warning on the strength of the previous post - Tim ;)
