Just wondering if anyone out there has experienced issues with MDR-8000 Local Oscillators or if you are experiencing any other reliability issues with this series of radio?

Thanks!

MDR 8000 issues

I have no experience on the MDR 8000, but will inquire of a friend who maintains a network here in the Northeast. I know they have had a slew of problems with the network management system, and I think he mentioned the LO's as well. I'll get back to you in a few days when I go see him.

MDR 8000 woes

Well it turns out the Alcatel has had a big issue with LO stability in the transmitters of the MDR 8000 series. My colleague reports that they have had a number of issues with the LO's not being stable and Alcatel making lots of changes in them. His opinion was that things are getting better but not perfect yet.

Bon chance!

LO issue

Thats what I suspected! I heard they have a new revision available in the last couple of months. We are experiencing difficulties with failed and microphonic LO's. The number of failures is unusually high. Like some other companies, some of which begin with the letter M, Alcatel isn't revealing much since there often is a customer request for some sort of financial consideration. In this case, replacement LO.

Thanks again for the confirmation.
