If your station is using any of those stand-alone Cobalt converters, there is a fix you should know about. The problem presents itself as something other than a power supply issue, but it ends up being a flaw in the design of the connector used by Cobalt on the P/S.
If you notice you have intermittant drop outs (causing the LED to flash), it will show itself as an input issue (like a bad input connector), however, it's not that.
On the DC connector (Wall-wart plug, not the unit's DC jack), the "center" sleve is connected to the tab using a rivet, so the tab can rotate on the sleve's rivet.
The problem is, as you can probably guess, this is not the most secure electrical connection in the world. When the tab slides on the rivet, it causes DC voltages to drop.
A simple dab of solder between the rivet and the tab to stop it from moving will solve this issue. I submitted this to Cobalt but never heard back from them. When I ordered the last device from them, I noticed the same faulty connector with it.
So just an FYI on this one.
