[time-nuts] Jackson GPSTCXO question

[Tom Clark]

I'm evaluating a Jackson GPSTCXO that was in a Symmetricom Eval Kit. 
It's showing impressive perfomance with just the antenna in the window. 
I'm using either the Z38xx or GPSCon software. Are there commands that 
would allow me to

 1. Force the receiver to do a self-survey and/or
 2. Force the position into "zero-D" mode by locking the position to a
    known value?

Tnx & 73 de Tom, K3IO (ex W3IWI)
