); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] Whats the problem disconnecting your antenna from the antenna port on the Splitter, connect your NTS-200, and then measure the DC-voltage on the Splitter antenna port?
Maybe you _want_ to build a DC-block... ;-) -- Björn On Fri, July 27, 2007 21:11, Jason Rabel said: > ); SAEximRunCond expanded to false > Errors-To: [EMAIL PROTECTED] > > I have a NTS-200 on the way, but one thing about them is their GPS power > output is 12V instead of the usual 5V.
