Oh, that arrived as called for - I have for some time been wondering 
about the "cracklings" in the Rx audio, not being able to decide whether 
it was a HW problem, an artifact introduced with the 3.036 FW, or 
atmospheric conditions, now that has been explained and fixed in one go 
- fix confirmed here!

The audio "bleed through" "problem" persists though, well the above was 
much more important to have fixed - Thanks again John Henry and TT!
(And by the way, it's now again possible to update the radio through  a 
Prolific USB-Serial adapter running from WinXP on a VirtualBox in Linux! 
That was somehow broken with 3.026, but I never properly investigated 
what was wrong)
