Re: Diagnostic software for uBitx #ubitx
Here's some old threads (rants) on this:
I got a bag of AD8307's from China, they are quite cheap and reportedly work well.
Should make a very sensitive detector for a tandem match swr meter, also useful for debug.
Though have not played with them yet, or acted on much of the above.
I have written a new version of the uBitx code that does tuning and calibration and
sweeps the two crystal filters to be plotted by the Arduino IDE via the USB-UART link.
But not quite ready for prime time.
