Hi
I’ve swapped out the GPS on a couple of them. Not 100% sure what went wrong.

I have a Z3801A that has lost contact with GPS. The GPS module is working -
the list of not-tracking satellites changes occasionally, but it never
tracks anything. I've tried swapping antennas and such but that hasn't

How often does the front end of the GPS module die?

I did a (rather crude - breadboard) experiment of using an analog vs XOR freq
doubler driving a flip flop. I did not see much difference between the $0.10
XOR doubler vs the $6 analog doubler.
Two $0.10 2P4T PCB mount slide switches would replace the relays. The total
parts cost for the
FWIW Re: the relays. I worked through the Omron discontinuation notices
for the first relay (I figure the original was a G5Y series, not GSY as in
the manual) and it looks like the G6K series, easily available at Mouser
and about $4 each would work, though you'd have to use a DPDT.
