Often times when operating a POTA activation, the Raspberry Pi computer does not have internet access. This can be quite problematic for logging, as well as running digital modes such as FT8, which needs accurate time for proper syncing. The solution is to pull the correct time from the GPS satellites. This can be easily done using a GPS dongle that is plugged into the Raspberry Pi. Per KM4ACK’s Build-a-Pi, this is a nice and easy addition to the Go-Frame.
The photo below is a side view of the Go-frame. I painted the GPS dongle black to blend in with the go-frame. Its located in the upper left corner of the go-frame directly above the PL-259 connector.
This photo also shows the Anderson Power Poles.
One problem I had was drawing too much power from the USB ports. With the Winkeyer, Signalink, and the GPS dongle all getting their power via USB, I added a powered USB hub to accommodate their power requirements. The powered hub is located right on top of the Raspberry Pi computer. I also added a Type 31 2.4″ ferrite to the coax that runs from the FT-857D to the LDG autotuner. This prevents RF ground loops. Its located in the bottom center of the photo.
Some really useful ideas in here. Thanks. I’m stuffing mine in a Pelican-type IP75 enclosure. 73’s de AD6AE
Thanks! There are so many ways to make a go box. I have seen a lot of Pelican-type go boxes, and hey all look great. I’m sure yours will work out as well.
