My poor-man’s 10 MHz reference based on the Ublox Neo-7M GPS module didn’t always receive GPS satellites reliably enough. Since I rely on reception indoors, conditions were sometimes too marginal to lock the oscillator output to 10 MHz. Inspired by the QRPlabs GPS module of Hans Summers (G0UPL) with its large 6 x 6 cm PCB groundplane, I therefore decided to do something similar.
It definitely helped make indoors reception in my shack much more reliable. The first picture shows the unit with the 8.5 x 6.5 cm single-sided PCB ground plane attached with double-sided tape. The picture below shows it prior to adding the ground plane. I also added a small LED to the right so that I could see from the outside whether the GPS locks properly.
This post is a continuation of these other posts about the 10 MHz reference:
