After reading Dennis' (W7TFO) thread in august about WWV et al getting the axe, I started looking at alternatives. I collaborated with my friend Richard, W4BYT, on this project and many others. Many GPS Disciplined or Referenced oscillators were available on Amazon and the bay, starting around $200.00. Looking at these I decided which features were desirable, but then considered building instead of buying. I find that I learn a lot with each new project I build. Such was the case with the GPSRO. It was a surprise that QEX offered a perfect solution by Elwood Downey (WB0OEW), four pages of information on design criteria and the basic circuit. His website can be viewed here: http://www.clearskyinstitute.com/ham/ and the entire QEX article may be found here: http://clearskyinstitute.com/ham/gps/ I am rather tired of hand-wiring these solid state projects with #30 wire (fishline), so I decided to prototype the circuit, evaluate the software, and then create a PC board to make the build a bit easier. I also wish to explore other methods and components for similar applications, so I am in the process of designing a universal GPS VFO board that may be used with a combination of different components. The cost of all the major components was less than $120 for this build, however it is possible to achieve the same results, sans graphic display, for around $40.00. (This option will be available as soon as the universal board layout is completed.) Major parts required are: $37 GPS module $14 GPS antenna (with amplifier) $39 TFT LCD touchscreen display $16 or $8 for DDS generator, (with or without temperature compensation) $4 Arduino Nano Microcontroller $3 Rotary encoder Other parts include the PC board ($35 for ten including shipping from Shenzhen, China) 2 resistors, 2 diodes, 12 capacitors, 4 regulators (one switcher, 3 linear) enclosure, wire, and hardware I will share photos here of the bare boards as received from JLCPCB, the major components, and the assembled board. In additional posts I will show photographs of the populated board, front and back views of working unit, initial test results, and inside and front views of the completed / packaged unit.
