What is your voltage on the status page? That should be close to 5 VDC.
Hi Again, The Coax on the GPS antenna is an unknown mini-coax and the output from the GPS module is only 3.2 volts.
The power supply is adjustable and it is set just where the CPU voltage measures 3.25 volts this is, on this board, about 5.1 volts.
The voltage at the e field pre-amp is the same more or less as the input voltage.
The GPS Pre-amp says 3 to 5 volts working, but it is limited by the GPS module itself.
What is more of interest is why something is causing the buffer over run, that does not permit both functions to happen at the same time? 
I have ordered the original cheapy eBay GPS antenna again, 3 weeks wait? As it did work until the landscaper weedwacked the cable! Angry 
For the other two antennas that I got to replace that one, I went a little more up-market and neither of them appear to work?
This would normally point to the problem being somewhere else, but as far as I can tell the board is not showing any errors, except when a GPS antenna is plugged in.

P.S. I see I have lost the station details at the server too. I have not tried to re-assign until I get something that works.
