 In 1978 I bought an Eddystone EA12 from Tom, G3YTO,
sadly SK in 1985. It used to keep my bedroom/shack
warm - thermal stability, and the glow from the dial
lights was comforting.
  My K2 has been on continuously since June 2005 except
for power cuts and the ARRL Field Day when I joined
three new friends operating 1E, with my transported K2
for a while powered from a solar panel for extra points.
  I have the LCD LEDs off most of the time.
 Short of a rubidium or caesium derived source, keeping
the equipment on all the time is a good way to stability.
