Listening on the 22:24utc pass of AO-51 just now and for the second day
running, the sudden distinct change in sound reception tells me that the
analogue signal is being switched over to digital for TLM collection
just as it gets to me in Florida.
If this is so then could we have a schedule of what passes TLM is going
to be collected please - we only get a few days to work mode L and I am
0 for 2 and I can not be bothered to waste time if the published
schedule is not going to be adhered too!
If its just not working in L/U then forget the rant!
