Dear Customer, Ticket 507061 has been resolved. The resolution proposed is: Dear David The testpoint for the 3rd local oscillator in the 3rd mixer stage of the TX board delivers a Voltage of 1.02V which is too high. Limit is 0.2V. Reason for this, perhaps aging or defect of a component. But we cannot repair the CMU200 any more. With best regards Winfried Jansen If you need further assistance on this ticket please login to our Support Center or contact us via email.

This definitely makes me avoid purchasing your products in the future. the right to repair This is something that every company should respect in our day. And it's a shame that you are in the same category as Apple Greetings David Azulay |
