OpenGD77

I was not aware of this satellite, thanks Roger!

For those who use the SatSat iOS app be aware that there are two entries that match the name of this satellite: UVSQSAT and UVSQ-SAT. UVSQ-SAT is the one that you want to use.

I have the Radioddity RS22 and I have issues with RF ingress causing pulsating interference when transmitting on DMR. It's bad enough that I will not use the RS22 on DMR.

Have you followed the instructions to install the OpenGD77 firmware on your DM-5R?

The CPS Integration section is what you are looking for.

* Time calibration option has been removed, because it is now longer needed. Very impressive! My GD77 is now keeping accurate time while in suspend more. With the time calibration option in the previous beta builds I could get it close but it still drifted. I'm curious, how was this accomplished?

How is the GD77 in practice on working sats? I've heard of plenty of people using Baofengs for the easier birds to hit so I imagine the GD77 could only be better, especially now. ISS is easy with GD77 and the Radioddity whip antenna. The uplink is VHF so you can mostly ignore its doppler shift and ...

Can you tell me your Lat / Long, and also what time / date of the pass. Was the shape of the pass correct ? On the polar display ? I'll try to replicate the issue, because the problem is not quite what I thought it may be. 36.736N 86.197W 2021-09-04 04:59:38 UTC The shape of the pass on the polar p...

What Max elevation did you phone report, Some higher number. I think there is possibly a bug in the prediction of max elevation for high passes, which I will need to investigate. It doesnt seem to be all high passes which are incorrect, just some of them. Phone predicted max elevation of 88.7° This...

Awesome job! Many thanks to all involved! I checked the OpenGD77 upcoming pass predictions against the phone app that I use and they were all spot on except for one. This upcoming pass for AO-91 has a max elevation of 89° and OpenGD77 displays a correct polar view graphic but it reports the max elev...
