In this test of Beta 4 I’ve configured minimum RTCM 3.x legacy GPS 1004 & GLONASS 1012 only, using in situ NetR9 and also a NetR5 base receiver.
NetR9:
NetR5:
RS3 Rover:

The radio log still contains constant complaints from the trimtalk450 parser about EOF not being found, but it is not force reading the complete message and crashing.
Radio log:
And here is a time associated example of a dropout in the Exceptions log:
I’ve also noticed a deeper issue, after some time the UHF appears to hang or at least become inconsistent.

It’s happened now a number of times, here is one event captured in the radio log:
