Nigel I am still here and agree the SXB is long gone. But I shared the code
and it was in basic.
An arduino with higher speed will do a fantastic job of replacing that very
simple code. It is indeed simple.
I have no plan to do that conversion but maybe I will some day.
The real trick was the timing chain that offloaded the control proc.
I do imagine that all of that can be done in one arduino.
I just picked up 3 of the stm32 units for $0 pretty much and they run at 75
The SXB was 8 bit so it was a bit messy with some of the counts and such
that were needed.
Hope that inspires you or anyone else that wants to take a run at it.
It does work and runs my LORAN C stuff just fine.
Lucky you to have at least one site running.
