Question: I understood that the uplink dificulties were related to some issues regarding 67Hz reception on the sat. If the COR mode doesnt handle 67Hz at all and is an "Open Squelch" mode... Should not "life be easier" to be repeated by the sat?.
Hi David,
When 67Hz detection is active, the satellite keeps the squelch open for a minute after it loses the 67Hz tone. In my experience, usually the satellite will keep its squelch open throughout all the pass or most of the pass. The satellite will keep the squelch open even if 67Hz tone detection keeps dropping all the time, as long as it detects the tone for a couple of seconds often enough.
It seems that the problem is not that the sat doesn't open the squelch. The squelch is opened but the satellite transmits only noise or a signal which is too difficult to copy, because the satellite didn't hear the uplink signal so well, but it's repeating it anyway.
That goes as far as I understand. Perhaps people in the Fox team will be able to confirm or comment on this.
