I was setting up an LM317 adjustable voltage regulator circuit to replace an old 1.35V Mercury D cell that was inside a Fluke 540B Thermal Transfer Standard.
I noticed that the output voltage was only stable when the input was below 7V, above that and its output increased with increasing input voltage.
I thought I would do a little video showing what I found, it may be helpful to someone that is trying to use the LM317 to build a power supply.

The latest video in the development of my channel expansion board for the cobra 148 using an arduino pro mini as its controller.
This shows my efforts to deal with the noise being generated by trying to use the arduino to directly drive the 3 digit 7 segment LED display.
I have now decided that I have to use the MAX7219 display driver IC, as even with added filtering the nose isn't quite good enough for SSB use.
Give this a Thumbs Up if you like it, it helps to grow the channel, also please share the video with your friends to help the channel to grow !

I will do a live behind the scenes mailbag, have a chat with those that join the stream, and then tinker at the bench with some electronics items, the Tektronix 851 and Arduino automatic camera switcher.
