The 10 MW, 140 GHz, CW ECRH-plant for W7-X is in an advanced state of commissioning and the installation was used to investigate advanced applications for extended heating- and current drive scenarios. The operation of the TED gyrotrons was recently extended to a 2nd frequency of 103.6 GHz at reduced output power and first results are presented. An improved collector sweep system for the W7-X gyrotrons with enhanced power capability and smooth power distribution was developed, results are reported.
