SolderSmoke Lexicographer

Mike, AA1TJ, is the QRPoet Laureate, but I think we can now officially name Steve Silverman, KB3SII, our official SolderLexicographer:

Hi Bill

Here is an interesting possible explanation for the term LID:

'It's a term that goes back to land based telegraphers, before radio was even used. Some say it has to do with placement of a tobacco can or lid to enhance hearing the telegraph sounder. Such things were apparently trademarks of the poorer ops.'

So there you, using a tobacco can sounder "hearing aid" defined you as a LID, as in using the lid of the can to tune your RIT.  But in telegraph location with lots of QRM, such as in a major telegraph office or along side of a noisy train track, the lids enabled an operator to distinguish his sounder from the background clicks and clacks.  The Car Talk guys would love this explanation.
