A series about all things Amateur Radio/HAM Radio.

Picture 1
Picture 1 shows the radio hanging over the edge with the front panel rotated down before rotating it back into place. It shows the cramped working condition I had to deal with.

Link to the YouTube video I used that described the process of removing the two backup batteries in a Kenwood TS-940S. The video was very useful and informative however as usual it looked far easier than it actually was or perhaps I’m just rubbish at taking radios apart.

Picture 2
Picture 2 shows the clock display immediately after first switch on with the display not working properly.

Picture 3
Picture 3 shows the correct clock display after pushing an internal reset button. I think the picture shows the alarm and timer settings. It eventually displays the correct time once it was setup. Unfortunately I forgot to take a picture of the final clock display.

Link to TechMoan You-tube episode where the hi-fi was destroyed by a leaking battery (Sony’s self-destructing MD Recorder from 2070).

Wikipedia article about an S0239 connector. This being the Antenna connector which I had to re-connect before being able to work on the radio.
