Batboard

Don't know if this is true or rumor, but I have heard that the R2600 series is no longer being manufactured.

They're still shown on their web site: http://www.gdsatcom.com/cte.php

Why not call Ed or Doyle and ask about the status of the product?

The core product has had a long run with the RF section having very little changed over the years.
The processor , display and option cards have been updated over the years but the basic chassis stayed pretty constant.
