Fred W4JLE writes that he has just discovered the NEXTION display and he has begun using it on his BitX.
He says “what makes it really neat is the software that can be downloaded from the manufacturer’s site. It takes all the pain out of graphics programming. I have replaced the UNO with an STM32 as in addition to the normal stuff I have added a GPS module.”
The display shows time/location/grid square data as well as using the 1PPS in the GPS module to do a continuous correction to the SI5351a oscillator. The higher resolution allows calculating the SWR etc. with much finer gradations.
Fred says he will be adding a filter board from a CODAN that will allow all band operation which he purchased for $12.00 on eBay.
Fred’s concluding comment is that it is “Amazing what is available to the homebrewer today!”.
We are eagerly awaiting a link to his sketch and to see photos of his uBITx!
