[Premium-Rx] WAS: R&S EK070 defect: help wanted

[C. van Ravenswaaij]

Hi all,

Thanks to everyone who has responded on this issue.
It took some time to find a good repairshop, then the PIC637 was hard to 
find _and_ hard to get shipped. Also a few other parts were broken, but 
now my EK070 is working again.

Best 73,

Cornel
