[amsat-bb] Unable to even call cq on CAS-6

Hi, during last pass over Europe of CAS-6 (2020-06-21 ~20:30Z) I've experienced the problem already reported here few days ago: even with 10-15W EIRP after a couple of seconds in TX trasponder cut off my signal. I'm quite sure to be not over beacon level. The beacon appares unmodulated. Heard few station calling but get only part of callsign for the same problem.
