Hi Hasan,
Many thanks for your observations and for your support of the FUNcube missions.
I suggest you have a look at our January update about Dashboards and other software. It shows a later version of the JY1 Dashboard was made available after the launch of JY1Sat and which should work better for you.

There is something not quite right with JY1 Dashboard software. If set exactly like Funcube -1 and NAYAF-1...it performs completely differently in terms of AutoTune. Even when on the wrong satellite, Both FC-1 and NAYAF-1 achieve a lock to the incoming signal., while JY1 Dashboard hunts and hunts. It eventually gets there, but it takes many seconds to get a lock on the very same signal that lock up the other two softwares immediately.
*All 3 programs are fed with the same audio source at the same time, on the same antenna. All 3 programs are on the same computer. Only the JY1 program is misbehaving.*
JY1 Dashboard Ver: 1.0.1178.1 Rev Date: 2018-11-28 21:30:22
Something is clearly wrong with this software. Hasan

I noticed JY1SAT Dashboard is not decoding as easily as the others ...by that I mean freq tracking. This morning I lost a bunch of frames because the doppler is not tracking perfectly yet. Even though I was set to autotune from 0 to 7500 Hz, as the sat freq leaked down (tones became lower), I lost lock. When they leaked up, later in the pass, lock was not lost.
Neither NAYAF-1 nor, FC-1 Dashboards behave that way.
BTW, the signals from JO-97 were a LOT stronger this morning. LOS was about 5 seconds early.

Hi Hasan, I first noticed this on my original lash up of airspy>sdr#>vbcable>dashboard and I was manually tuning and as doppler marched the signal through the passband I learned that moving it back up too quickly would lose lock and seemed to have trouble re-locking, so I ignored this as being on my end and manual tuning. I now have it running on a funcube dongle and still see it, I'm still getting a feel for the real downlink and doppler swings so my range may be set a little wide, I will try closing it in and see if that helps.
Thanks Kevin

Hi Kevin, I did a TLM run with JY1SAT about 90 min ago and left the decoder
running
(as I do with all my TLM programs) AOS in about 9 minutes here, and assuming the TLM is on, I'll let you
know
if JY1 Dashboard takes off or not.
17:19z , JY1SAT came right up, and it Dashboard is locked and decoding fine. I have about 11 frames and am at 9 deg EL.
Just for comparison purposes, I have my AutoTune range enabled, and set
for
0 and 3500 73, N0AN
Also, the signal has been considerably weaker and with a lot more QSB
than
I see on either AO-73 or EO-88. I'm seeing a LOT of polarization fading
as
I switch back and forth between a RHC Eggbeater and an X200 Colllnear.
Even
at 40 deg EL, seeing polarization fading on the RHC EB.
Also noted, doppler tracking is not as "perfect" as it i s on AO-73 and EO-88. I assume this is due to some slight error in the TLE's
I also just adjusted my tracking Auto-Tune high end to 6000, as it lost some decodes with the high end set to 3500

Kevin,
Yes, I was also running simultaneously the telem software latest
version.

Hi All, Is anyone else noticing any issues with the JY1-sat dashboard? I can start it with the sat present and it will instantly lock and track, next pass it will ignore the signal, kill it and restart it and bam instant lock.
