I think I'm suffering from wet-trees-in-the-line-of-sight syndrome, but
now have what looks like a good and up-to-date set of channels on the
MyGica T230, too. All channels are now in the range 1 to 800 and all
were reported as "probable" during the scan, which started with all
During a sequence of scans all transports locked and found probable or
possible channels; but some unused transports were reported. They
weren't identified, but could be traced. I expect nine. As would be
expected with a poor signal, they weren't the same ones every time. I'm
seeing a lot of "pes length... cannot be queried" errors at present.
The mix of identifiers reported, and the usually long intervals between
needing to do all this, still make establishing channel lists feel
unpredictable - but in master now I find it much better than it used to
be. And then the trees were smaller and there was no need to switch
delivery systems. Thank you!
