This project is a GPS locked combination frequency counter/frequency standard.
It's designed to work with the . It runs on an Arduino
Nano and uses a 4x20 LCD display. An Si5351 module is used as the frequency
standard.
. Included is the software for
the "GPS_Counter" program, a document that describes how to build and operate
it and the Gerber files for the printed circuit board.
A second program, "Where_MI" can be run on the same hardware and provides
traditional GPS functionality.
If anyone is interested, I have about a dozen of the PCBs that I am willing
to part with for $5 each with free domestic shipping and about a dozen
earlier PCBs that do not have the preamplifier stage; these work fine for
3V3 or TTL signals. You can have those for $3 each with free domestic shipping.
Email me (good on QRZ.com) if you want a PCB.
Enjoy!
