Some fellow HAM’s told me that my transmission sometimes “gets lost”.

Some time ago I have found two possible reasons for this problem.
First possible problem was well known “thermal faliure”. After opening my radio I have found the suggested modification allready made, so I had to look further.
After some search foud an article describing the problem with VIA’s (VIA – latin for path or way, electrical connection between copper layers on printed circuti board), so I made the modification on my radio.

I hope the problem is solved, waiting for the feedback from my fellow HAM’s.
