OpenGD77

I provided the location for QTH locator JO71SG. I guess I couldn't have made a mistake. Data for the ISS from two sources. Why don't they converge? https://celestrak.org/NORAD/elements/amateur.txt: ISS (ZARYA) 1 25544U 98067A 24007.20598554 .00207552 00000+0 35328-2 0 9994 2 25544 51.6389 37.9443 00...

You're talking about an accuracy of up to a few seconds, but I'm talking about a delay of more than twenty minutes. A few seconds would be ok in this case. What other sources can I download Keps data from? Is it possible that despite downloading data, I still have old "Keps" data on the radio? I hav...

Hello, I noticed in my Retevis RT3S a large discrepancy in the calculated satellite flight times in relation to the actual location of e.g. the ISS station or the Heavens-Above program. The differences are significant and for individual flights they amount to over 20 minutes. I have entered the coor...

Hello. How can I add CTCSS when working via a satellite that requires it? ISS requires 67 Hz CTCSS on uplink. I found: When using the satellite functionality the operator does not need to set the satellite frequency or CTCSS, as these values are uploaded from the CPS as part of the Kep's data and d...

Thanks for making me aware. Regards.

Hello everyone. I became interested in DMR, so I bought a Retevis RT3S radio and loaded OpenGD77. This is why I am here
By the way, I wish you a Merry Christmas and a Happy New Year.

Good morning, I am using CPS OpenGD77 version R2023.11.26.02. I tried to read calibration data from the Retevis RT3S radio. Even though the program seems to be reading something, there is no data in the Calibration window. I have not been able to determine the reason for this behavior. Maybe someone...
