Hi
The biggest issue I see is that the module thinks it’s in the vicinity of New
York City.
Since it’s in position hold mode, it’s not going to lock up at your location.
Next step is to watch the module dialog as it boots up. See what the CPU
on the board is doing to the module at power on.
Quite difficult to see. But it appears the gps antenna cable is just
hanging there not connected to what I presume would be a antenna.

Its definitely VC TCXO. For the tests, I disconnected GPS-FC embedded
antenna and connect it to my GPS distribution amplifier. In this case I
could have GPS signal indoor. Its not perfect. But should be enough for
troubleshooting.
I soldered TTL Serail sniffer to GPS-FC and I got
I would love to be there and it looks like a great program - but they have

Hi Corby.
Paul,
For the testing purpose, I connecting GPS-FC to my GPS Distribution Amp.
This is why antenna has disconnected on the picture. When I testing this
unit - i connecting coax to it.
Yesterday, I connected TTL serial to its Motorola Module, to see what is
going on there. Here is
Thanks for the replies! Very informative.

The example circuits given on that webpage will be inferior in every way to
RTL and DTL logic from the 1960's, which itself is inferior to late
60's/early 70's TTL.
A good reference on how to do discrete transistor logic design from the
1960's, is TI's book Transistor Circuit Design. I just poked

Hi
All five of the Wenzel Oscillators have been paid for and sent via USPS.
That was quick.
Thanks
