So absolutely funny today and this thread.
I now have 8 GPS rcvrs austrons, odetics, HP etc
I just built a sleezy 1 X 8 splitter using Home depot 2.5 Ghz splitters.
Have been doing this for years but with a 4 X.
This issue exactly bit me. I put all the rcvrs online last night. One was
acting goofy. Thought, well its old will have to troubleshoot it.
Nope a 330 ohm to ground on a BNC T fixed it right up.
Guess I should take my own suggestion some times. :-)
