My present project, is to fix a fine old, but still fairly modern fancy radio receiver. A Yeasu FRG 8800, with the optional narrow filters and VHF band. It developed issues just out of guarantee, in that the display began flashing and all audio would cut off as it warmed up, which is the indication that the PLL has fallen out of lock. Which is a well known issue for the unit. I worked my way through the suggested fixes, but nothing worked and eventually it flashed with the problem near constantly. In the middle of which the VHF section suddenly became insensitive, I then got something more up market and put it aside for when I had more time - like a couple of decades ago
I have just this past week found the time to take another look at it and recheck the suggested mods to fix it, long ago. All were correct, but still no PLL lock, so I'm delving even deeper, with nothing to lose.
Between times, I'm delving into my home heating systems control possibilities - trying to make it a little more sophisticated, trying work out what fancy units are compatible with what I have installed at the moment.
