the 2 x AAA batteries completely ... anybody got any ideas (serious
replies only preferred <g>) to show that the power switch is on?
Wire the On/Off switch so that it also activates (via a relay) an air
compressor when turned on. Feed the output of the compressor to a horn from
a diesel locomotive (http://www.trainweb.org/mdamtrak199/PImages_000a.htm)
mounted to the rear wall of your radio room. If the horn is still sounding
when you finish your QRP operating, you left the speaker switch on.
