Hi Magnus, thanks for that information. I had forgotten about that Plessey
GP2010 and GP2015 RF chip. The only problem is that you have to do a divide
by 7 on the 40 MHz signal that Plessey did in the GP2021 correlator IC.
Using an old SuperStar RX is a good reconmendation. Thanks. Doug, k4cle.

Don't know what levels are required. However, I do know that Meinberg's
model GPS-ANT is compatible.
It is expected from the use of the Zarlink frontend chip, which takes 10
MHz, locks a 1400 MHz oscillator to it, divides it down by 10 to 140 MHz
which is then used for first and second LO.
Thus, 1575,42 MHZ becomes 175,42 MHz and then 35,42 MHz.
You could hack a GPS module with the GEC Plessey/Zarlink frontend to
achieve this.
Cheers,
Magnus
